Most questions now are Fiero specific...and actual owners who had done most of the mods like Gixxer and Nano are more likely to give the correct replies..... since I don't own one, my replies cannot hold good, and hence the silence from my end...

As the bike is drinking oil, its high time that the bore has gone bad.
Get the work done before you spoil your cam.
You can opt for a stock bore, go for the rtr bore only if you have the option of getting the head work done easily...
Either ways it will cost the same!

As your buying a new bike already go for stock bore and keep the bike fresh, it helps a lot...

Thats not any easy anyway in a small town like ours and also had read in many of your posts that reliability does take a beating while going for BB so opted out .
Going for a new bike but not in the near future may be in a year or six months.
No bike impress me now don't know why? was waiting for cb150 streetfire and it went a disappointment after the launch of updated dazzler.

@psr thank you buddy for the replay.

And to all of you guys what other bike can be bought now can wait for good launches also not at all in a hurry.

@Psr @Nano

Well since Ava rose has taken a sabbatical from SBK performance after becoming a mom,i've been on the lookout for someone else with similar chassis. Jokes apart,my bike's clutch plates have worn out,so i have decided to go for the china made, 200 buck crap which comes as OE now. Next time around i will upgrade the whole clutch assembly to that of the RTR which should cost 3k+ with the clutch cover.What it'll do is solve the weak clutch issue we have with the licensed FCC made in china one.The stock clutch plates of the fiero were made in japan by FCC and used to cost 1,500 bucks back then.But TVS has from a long time has been importing the cheap crap from china and hence the issues associated with it.I have MOTUL 5100 bottles with me,but since there's no guarantee as to how long the chinese ones will last,i'll go for the diesel oil recommended by Psr or the gulf pride w50 for now.

@ gixxer_junkie_m buddy you guys are surrounded with good mechs to do what ever you wish to do, then best of luck for your clutch work.

If possible pls be active in this thread bro .

I wasn't aware of this forum for a long time else I could have made many mods in my bike in its early stage itself.

Btw this is my boy a1.5 years ago.



this one after restoration



look at my handlebar for trademark 007


more recent pics with fz handle bar will follow in coming days

A very well restored bike.She sure looks good with the apache front.Yes,bangalore has a lot of people who are good at these things.I am glad too that because of these guys i can get these modifications done.Fiero has a engine design which makes it a popular bike for modifications and whatever TVS has come out till now,or will come out with in the near future will attest to this fact.So when they say a certain modification can be done,then you and i can be sure that it will work.Similar with the RTR bore mod,all it needs is a good knowledgeable mech and a decent enough lathe.There are hundreds of fieros running on streets with the RTR bore here,their reliability is equal to stock!! Think about it,the bore kit is stock and when a RTR head is installed along with it,where's the issue about reliability?The prob arises when other things are done like K&N etc.But yes,if there's lack of good mechs,then such works are better left alone.
Do keep active in the thread and then guys like Psr will become active too.

I think its not too rich carb, its the throttle slide getting stuck, or the float getting funny. Used to happen to my carb until one day it decided to drain all the fuel that's left in the tank, even while riding.
Send the pics of the spark plug here and just get your carb cleaned once, the float will be re-fixed and the slide and everything will be nicely removed and fixed back. If its a stock carb, I think that's all it would need to get working back again.


Hey,yeah I didn't think of the slide. Last time around I cleaned the carb (it's stock) - it was sliding fine. Will check it soon. Will get around to posting the pic of the spark plug too as soon as office life permits :P
Congo on the new chain drive, enjoy the newly-resurrected torque!

Why don't you try the KTM 200?

And your bike is done up very well. It looks showroom new. I see that you have added the FX turn lights to the Apache cowl.

KTM200 ? no buddy r15 v2 also no no. I ride with pillion 60-70 % time daily 40-50 kms. but thank you for the suggestion .

about the fx turn lights its a long story .

we all know how useless the oem headlights are, I had it for about 5 years and the night visibility dropped a lot due to that met with with a accident and broke my wrist bone so decided to go for fx headlight setup 2500rs within one week my brother in law broke the headlight ,was very tight with finance so went for max100 head light 500rs but the turn light stayed there and it is still there even after the apache setup . kinda liked it so left it like that.

I guess CBR 250R is the best bet.
Has great torque and nice acceleration, best suspensions and really really comfortable...
Not to mention, still does 140~150 with ease.

Yeah
i have a lot of interest in cbr250 but the price is way high atleast by 30-40 k above my budget (if no other alternative can adjust) and my cousin who owns one claims of 22 kmpl (cannot adjust ) which is again not practical for my riding so confused a lot so will wait for 6 months to 1 year then can decide and for now I have good friends like you all to advise me to get the best for my buck.
Thank you Nano

@gixxer_junkie_m so in your point there is no problem about reliability na? but no one here is ready to work even if I am ready to take the risk ok one big question what are all the things should be changed if i had to go for rtr bore ? pls make a list if possible.

Really nice work. But IMO, the Apache headlamp and Thunderbird/FX indicator doesn't seem to have good chemistry. Keep it running!!

BTW, Sold my Thunderbird and got myself the Suzuki GS150R. My obsession over the Fiero is the reason why I went with the Suzuki. Lets hope it is nearly as good as a Fiero.

Well, to be honest I too was in the exact same dilemma as you are right now.
I own a Ninja 250R currently.

The thing is that if your willing to keep the fiero, for the new bike the milage isn't an issue as big as it seems looking at the number.
CBR is a really soft and friendly ride, not to mention comfortable too, a friend of mine is getting 30 KMPL on his CBR on average riding, I get somewhere in the 25ish range on my green bike.
However after being used to the small size and easiness of the fiero, you wouldn't ride the CBR as often as you think you might, even the service interval (oil change) of that bike is around 6000 kms.
It all seems very expensive looking from the outside, but believe me its not that bad.
You wouldn't ride your CBR to work everyday and negotiate in traffic, you would prefer relaxing and thrilling rides doing justice to the bike you bought.
Plus either ways a biker inside you deserves something next gen and latest, rather then trying to re-learn the art of riding on a 10+ year old bike.
I do love my Fiero more than the green bike, but now-a-days I don't abuse it the way i used to as I have something which has enough juice to quench my thirst.
Once you ride something really really better, you'll understand the limits and possibilities of your machine and your own too.
It would develop your skills in such a way that you'll get sensitive to the response of the bike and would inturn find yourself much happier on the bike you rode this far.
You would keep fiero as a secondary bike to go to nearby places also in traffic and take it to places where you can't park your CBR.

You'll end up using the fiero only and only when you need to commute, for real biking and real pleasure, you would always ride the CBR, which will make you grow and provide the much needed pleasure for the biker inside you.
I would really recommend you to go for it.

Also if possible, do test ride the Ninja (if your up for a used bike) as spending a bit more of money, you can get a used Ninja which is much much better.


Congrats Vignesh...
Any particular reason in mind for picking up the GS?
Seems really soft to me though, with not so good brakes.
but I must admit the engine can give the R15 a run for its money.

I am sure you already have some ideas for putting the GS under the knife.

1. Do you really think so ? well pls forgive me to leave it as it is
2. Suzuki GS150R. Really surprise for me also I think it is a soft but good bike. but you are a dirt racer you deserve a way better ride atleast a ktm 200 if not a ktm390 any way congo for your new ride and happy miles munching .


1.Yeah I know you own a ninja and had read that posts more than twice ( I like the way you narrate buddy )
2. Definitely my boy will be with me even if I get a busa
3.don't know why but I am so much concerned about mileage ( middle class mentality may be )
4.my office to home is 18 kms in that 14 kms is state highway but you cant cross 60-70 kmph mark cause of sudden surprises ( populated villages on both side )and four kms is narrow town roads cant cross 30 kmph .
5. Not much of tourer because of family and nature of work and my family wont allow me in bike for long rides .
6. leave alone test ride a ninja, I am yet to see one in my town even spotted a hayasung .

What about cbr 150r the story of lack of low end keeps me away from this bike .Will seriously consider cbr250r from now onwards.
BTW what do you think of speculated Suzuki insuma twin cylinder 250cc ?

@Max

I think that,it'd be better if you get the fiero block re-bored for now.For RTR mod,the easiest way would be to go for RTR bore kit,cam chain tensioner and get a used RTR head assembly.

@Vignesh

Good choice.Suzuki makes some of the smoothest mills around and GS is a typical suzuki engineering example.I wouldn't be surprised if that engine is designed on the same lines as that of the fiero,meaning lot of potential in the design for modifications.Check and see if it has oil cooler addition designed into it.Recently an uncle of mine bought the suzuki hayate and that engine is built to take abuse like anything,i mean we took it on national highway and riding doubles it can hit 100,sitting upright,with a two up weight in excess of 180kgs and cruise all day at full throttle without any sign of NVH/engine fatigue!It even has a replaceable oil filter.Subsequently another friend bought a hayate too a month back after test-riding it.I mean both of them are mileage conscious and not interested in power etc,but one thing's for sure,suzuki engines certainly are more capable than what the specs on paper might suggest.
