Re: Fiero/FieroF2/FieroFx

Congrats man that's a neat looking bike

Re: Fiero/FieroF2/FieroFx

Thanks. Bike will be collected tomorrow. BTW what's your opinion on my planned mods. Also eager to know the opinions and suggestions of the regulars on this thread.

Re: Fiero/FieroF2/FieroFx

Well I don't remember too much of u r plans or upgrades that you have posted. One thing is for sure man IMO keep the stock bore and head aside and go for rtr180 set up and work on it on increasing capacity etc with p220 piston etc. Gixxer has run on zma piston and now running with rtr180 set up. He has done most trials and errors on fiero in this thread and you can close your eyes and follow his lead cos he has been there and done that. I have known him and his bike for last 6yrs and have ridden it in all its avatars. The compression of 220piston on stock head is too much and you will have hard time kick starting the bike or jetting it to make bike run perfect on max 29bs carb. So if I were you I would have kept it simple and gone for tried and tested set up of rtr180 and bigger bend pipe for silencer with a bs29 carb. Other disc brakes and swing arms are very much needed with increase in power

Re: Fiero/FieroF2/FieroFx

Just look at the previous page.

Shouldn't that be either go for rtr180 set up or increase the capacity of the stock block with P220 piston etc. I'm not going to buy a brand new 180 bore and then rebore it. I'd rather rebore the 70K used stock bore.


And that's precisely why I am on this thread. I'm not planning on doing any trial and error. People have already spent enough time and money on that. I'll just copy what has worked for them.

I don't know him personally but he has contributed enough to this thread for me to trust him. Same with you and the other regular contributors to this thread.

That's precisely why I'm asking for suggestions. Though using a P220 piston will give me bragging rights, I want a bike that useable and reliable. So if 180 is the better option, that's what I'll do. I don't intend learning from my mistakes. I want to learn from the mistakes others have made. That's the beauty of forums. Also someone suggested to wait for the Apache 200 bore kit. I may just use the stock 150 set up for now and concentrate on the other mods and go for this bore when it's available.

Anyway the bike is being picked up in a few hours from now but I'll only get to see it by the end of June when I get home.

Edit: The bike is finally mine!

Re: Fiero/FieroF2/FieroFx

Thing is stock bore and head is hard to come by so I advised to keep it stock. And you don't need an brand new rtr180 bore and head to work your way up. A 2nd hand bore and head would be good considering your final plan is to put bigger piston. Well Apache 200 is here but I guess it should at least take an year for the bore or head to reach gujris. Keeping aside stock bore and head will give u peace of mind of reverting to stock anytime without the headache of running around for precious spares.

The bike needs some work. Theirs rust in silencer and rear suspension has some rust too. Get it back to good shape and you can take the engine work for later after you have clear plan of how to go about it.

Wait for some more advises from other seniors as they might have better suggestions

Cheers

Re: Fiero/FieroF2/FieroFx

OK. But then the Apache 150 bore and head is the same right? At least that what I thought I read somewhere in this thread.

I'm not sure I'll find one in Goa. The RTR 180 is not such a common bike and being a reliable bike, finding 2nd hand bores won't be easy.

I was thinking of a brand new Apache 200 bore and head.

If I ever need to revert to 150, can I not just use a new Apache 150 bore?

I'll probably just replace the rusted chrome parts. Works out almost same a re-chroming and lasts longer than re-chromed parts. The Chassis is definitely going for a paint job and probably the engine bottom and wheel hubs. The Tank and body panels will probably be ok with a good polish. Front indicators will be needed.
Can the F2 tail lamp be fitted in place of the stock tail/turn indicator combo without modification to the panels? If so then I'll do that and go for separate turn indicators to match the front.
Also got another crazy idea. If I find the tank and body panels of a Samurai or Flame etc in scrap, I may just fit those.


Looks like they are all busy with newer bikes these days. Waiting for comments from Gixxer, Nano and others.

Just as [MENTION=15687]abhilashabhi12[/MENTION] has put it,p220 piston with stock fiero head will need a lot of work when it comes to dealing with compression.The fiero bottom-end can take the compression,but it will need proper jetting at the least.He has ridden my bike in all those settings and after having experienced it,he opted for the 180 set-up.

First take a look at my bike's pics,it will give you some ideas.

Disc brake is needed and i'd advice you to go for the pulsar disc set-up.

Tacho? it's needed and go for a analog one.Right from a long time,as you can make out from seeing the dates when the pics were taken,i've been trying to get that cafe-racer look.

Swing-arm? Victor glx is the shortest and it will be the easiest to set-up.If you go for longer swing-arms,then they will need sprocketing to be done to ensure the chain slack is right. Unicorn mono has already been done and it will need other mods too.Like putting a different air filter,which will once again need changes to carb tune etc and if not done properly,then it will ruin the performance as you know very well. RTR and other bikes swing-arms can be put as well,but they will all need different sprockets and most importantly the alignment has to be maintained with proper welding work to fit the rear shocks at a different position.If not done properly,then as you know,it will ruin the handling and wear out chain sprockets and even the bearings of gearbox.Extending the swing-arm will get you aesthetics and stability on long turns,but it will rob the bike of it's characteristic sharp handling.

Apache 150 was clocking slower than a stock fiero on the straights of the race tracks,hence tvs racing team in stock category,they were still using the stock classic fiero when apache 150 was there. Classic fiero was hitting 118 kmph actual speeds on the straights,that too with old testing equipment of overdrive mag,which was heavy and was mounted on the pillion seats back then ,when they were doing track shootouts of the bikes.What apache 150 head will give you is instant pickup.

Silencer mods will be needed depending on what set-up you opt for.It will need both bend-pipe mod as well as silencer mod.My bike is running with a 32mm inner dia bend-pipe,with the baffle removed and end-pipe dia increased.

Me and Raman were at Venugopal's place a couple of days back and he was saying SUZUKI FXR150 heads can be sourced and as i had mentioned earlier he had fitted it on his fiero as well. So that's also a option which me and Raman have been thinking about,along with the RTR 4valve head option.

Re: Fiero/FieroF2/FieroFx

I tried searching the net for the Pricol unit but could not find it

I'll probably keep the stock 150 bore for the time being. Once the Apache 200 bore becomes available I'll decide between the 180 and 200. Will drop the P220 piston plan.

For some reason I am not able to see most of the photos in this thread.

Any idea of the current price. My rims are also rusted and I'll need to change those. Should I buy the pulsar front wheel so the disk is a direct fix. What about putting a set of either Pulsar or Apache alloys. If the difference between new spoked wheels and new alloys is not that much I'll go for alloys.

I have already ordered a small digital one from Aliexpress. See my post on the previous page.

Any advantages with this one other than looks?

If it's not too difficult I may opt for this. Any advantages over the Victor GLX or stock?

Ok. I can safely drop this from my options list then.

If I find an Apache 150 engine in scrap I'll just put the 180 / 200 bore on it and plonk that engine into the bike and keep the stock engine as spare. With the Apache engine, I'll get the 5th gear and self start. How much is the going rate for scrap Apache engines? Keep an eye if you find any and let me know.

My set up will be either a 180 or 200 Apache bore with either a Fiero or Apache head depending if I find an Apache engine or not.

Do you have the specs, so I can get it fabricated?

Is the baffle and end pipe mod reversible? Don't want to spoil the original silencer in case I revert to stock 150 set up. Alternatively can I buy some other silencer and mod it?

Head is not a very big item. I can easily carry it in my baggage in case I visit a place where these are available.

Re: Fiero/FieroF2/FieroFx


I'll start with the alloy wheels options first,because choice of this will decide not just the disc brake kit,but also the entire fork itself.

If you opt for either the RTR alloy wheel,or that of the pulsar,then both would need the entire fork to be changed,preferably to that of the RTR's.The other option is that of going for the cbz extreme's,it might be narrower than that of the rtr/pulsar's,because cbz extreme's speedometer worm is the one which fits with my bike's pulsar disc brake hub.I personally prefer wired wheels over alloys,as i want my bike to have that cafe-racer look.It fits the idea of classic british cafe-racers,because fiero has been modified mechanically ,just like the 50's and 60's ,when guys were modifying their rides themselves to suit their style and on a budget.

It's not my job to discourage anyone's enthusiasm to modify their rides.In fact, i perhaps am the one in this thread who encourages modifying for the sake of it! So,if you were to ask me,i'd advise you to go for the mono suspension set-up,it has been done and it can be done easily.It's just that i was giving you a idea as to what it entails earlier.

Coming to the silencer mod.The stock fiero has a inner-pipe,that is in all bikes there will be a inner bend-pipe which has a air-gap,such that the bend-pipe doesn't become too hot.In case of the stock fiero,this inner bend-pipe is 18mm. What you can do with the 180 set-up is,you can get a bend-pipe fabricated which is 29.5mm. Bigger dia bend pipe as you know will mean less initial and mid-range.But it will make the engine breathe freely on top-end. My bike has bend-pipe and it's 32mm.It doesn't have inner pipe that is.What i've noticed from this mod is that it has increased engine refinement drastically and the engine revs freely at the top.It certainly has increased top-end performance,but has reduced the initial and mid-range.
This bend-pipe mod is very important,because without it,the engine will feel choked past mid-range.You can get a used RTR 180 silencer for 1k,but it will be a used one and hence will have issues of rusting,as powder coating generally doesn't last as long as a chromed one.Then you have to remove the cat-con from the RTR silencer,because such silencers aren't as efficient performance wise ,in comparison with the megaphonic silencer which the classic fiero comes with.
You can see in my bike's case that the silencer externally,looks stock,it sounds beautiful and it's more free flowing now too.

Yes the silencer mod is reversible and it's a matter of welding work.

If you can find a FXR150 head,then get one,because nothing improves performance like a engine head.Depending on what price we can source FXR150's head here,it is me and Raman's first choice.

Re: Fiero/FieroF2/FieroFx

Why entire fork? I thought only the lower portion of the right fork would require changing due to the Disk Brake mounts.

What's the advantahe of this over the Pulsar/RTR set up?


I'm fine with spokes too. In fact if my wheels were in good condition I would have stuck with a spoked set up. It's just because the wheels are rusted and I have to change them anyway, that I kept the alloy option open. However if alloys are significantly more expensive than spoked wheels, I'll go for spoked.


I'm not to keen on the Cafe Racer look for my bike.

Let me re-think this then.

OK where can I get this larger bend pipe from?

I'd still avoid modifying the stock silencer if possible.

I hope I can find one.

Re: Fiero/FieroF2/FieroFx

Alloy wheel and it's speedo worms of the RTR/pulsar need wider forks.You have to go to workshops which modify silencers for the bend pipe and get it custom made.Usually such shops will have measurements of RTR bend-pipe and they will replicate the same on pipe bending machines with the diameter you specify.Then you would have to get a collar made to fit it to the head from a lathe.

Re: Fiero/FieroF2/FieroFx

I'm now reading this entire thread for the 2nd time trying to gather enough information. Trying to compile the following information so I can go armed with it to the mechanic.

1. Disk Brake: For now decided on a Pulsar unit. I gather from the thread that I need the following:
- Pulsar Classic Right Lower Fork tube
- Disk
- Calliper
- Hydraulic pipe
- Brake lever
- Hydraulic resevoir
- Fiero F2 Hub (Can I use a Pulsar Classic Hub?)
- CBZ Classic or Yamaha worm
- Anything else?

2. Big Bore: Tentatively decided on the RTR 180
- Bore kit (Bore, piston, rings and gaskets)
- Cam Chain tensioner
- Stock head to be matched on the lathe (can someone post a pick of a stock head and one matched to the 180 Bore)
- RTR head is another option (photo please so I can see the difference)

62mm bore= 175cc.(RTR160 bore kit)
62.5mm bore =177cc (RTR180 bore kit)
63.5mm bore = 183cc (CBZ classic piston)
65.5mm bore = 195cc (ZMA piston)
67mm bore = 204cc (P220 piston)

3. BS29 Carb: Already know that I have to buy it from Bajaj or the UCAL distributor
- Do I need to change the jets?
- Intake manifold of the RTR 180

4. Swing Arm:
- Victor GX (1240mm)
- Victor GLX (1260mm)
- Fiero F2/FX(1270mm)
- Apache 150(1260mm)
- Apache RTR 160/FI(1300mm)
- Flame (1320mm)
- Apache RTR 180(1326mm)
I think the Victor GLX one fits without any mods right.

5. Oil Cooler:
- As per the Apche thread
- Edit: Just read that Gixxer has done it on his Fiero

6. TCI Conversion:
- TCI unit= 650 Rs .
- Ignition coil = 450 Rs.

7. Exhaust mods

8. Cosmetic mods

9. Other minor mods like FZ handle, rearsets (what exactly are those),

10. Equivalent parts for the Fiero from other TVS or non TVS bikes to replace hard to fin Fiero parts or to improve the bike.

I would appreciate if everyone could contribute info and one person compile it all into a sort of a guide listing each and ever mod that can be done to the Fiero in the following format:
- Name of the mod
- Brief description
- List of parts with approx prices
- Procedure and labour costs

This can be a pinned post at the begining of the thread which can be a quick reference guide to anyone wanting to do it.

And once more can someone Please Please Please share a PDF/Scanned copy of the owners manual and service/workshop manual.

Re: Fiero/FieroF2/FieroFx

Knock Knock. Where is everyone. This thread is gone dead. Can someone help me with my newly aquired Fiero?

Re: Fiero/FieroF2/FieroFx

1. Disc brake:

If you choose pulsar disc,then you'd have to get pulsar classic's hub.Your other options are classic unicorn,the spoke one.The speedo worm will differ with each option you go for.Classic pulsar set-up will need any of these cbz classic speedo,splendor,cbz extreme,ZMA as well.You have to do some leg-work yourself,classic bullet comes with spokes,so you can find out whether it's hub will fit or not. Then there's the most recent one with spokes,which is hero off-road bike,which is so rare,that at the moment i can't even recall it's name!So you have to do some research and find out as to which is easily available.If you opt for the f2 set-up,then speedo worm will be difficult to find and that means you would have to get suzuki zeus's spares.Even suzuki zeus came with disc brake,so that's also an option.

2. I have the stock head modified to match the 195cc,so i will post it's pics soon.

3. Jetting has to be done whenever you make any changes to the engine,without it,there's a serious risk of you experiencing what nonotech did,which is pre-ignition and seizures .Jetting is something which is to be specific to each set-up.So you have to get it done on a trial and error basis.On the other hand,if you decide to keep the stock carb,then you can simply install the rtr 160's 105 main-jet and be done with it.

4. RTR swing-arm is the one which will give your bike some serious presence.But none of the above will come close to a mono-shox set-up though.If done properly,this will improve handling and dynamics of the bike as well.Glx's swing-arm is the one which will need minimal changes of the lot.

Re: Fiero/FieroF2/FieroFx

This reminds me of the IT department of most companies. If you report 5 problems with your computers, they will fix only 3, leave the other 2 as they are and introduce 4 new problems into the system.

Just for curiosity sake, how much was the asking price for the RTR engine.

BTW I just ordered a Quick Action Throttle for my Duke 390. I was wondering if the same mod can be done on a Fiero.
