yes I'll get porting done..

high lift cam ??
damm, things keep on increasing..

so in my to do list the things are..

1- buy an Apache 180's block
2- buy spark plug (stock)
3- buy jets (115)
4- buy gaskets and three bond paste
5- get poring done
6- get boring done from 57.5mm to 62.5mm of the middle area which is the combustion chamber.(correct me if i am wrong)
7- head unit which holds the cam shaft also needs to be widened?
8- carb tuning at the end of everything.
9- buy a can of elf moto pro gold..

i intend to keep the stock air filter and the stock exhaust even later..
free flow one is useful on higher revs only (as much as i know)

am i missing something?
correct me if i am wrong..

and where is bprags, i wanted to know what mileage is he getting from this mod, just for information only..

Guyz today i got my front disc pads changed. it cost me 350bucks!! now the fronts brakes r working fine!! there is one point i wanted to tell u all is that our bike silencer will not be available any more, even if u place an order at the company. the company(TVS) itself does not have it!!! Shocking isnt it!

correct me if i am wrong. this was told to me by the service center manager..

oohh my god..
how can that be?

parts should be available until 15 years from the time of discontinuation legally...

damm.

ya i know, parts should be available for 15 yrs after discontinuation of a particular model. the manager told me that a F2 had come to his service centre and that guy wanted to change his silencer since it was badly rusted. they checked all the TVS godowns in Pune and didnt find one, so he placed an order to the company. the F2 owner had to give the chassis and engine number which was forwarded to TVS company. This process is called VOR (vehicle off road). But even the company unfortunatly didnt have the spare.

But i would like to mention that one friend of mine (also has a F2) was lucky to get a new silencer through this VOR process (abouts 1.5 yrs back).. He had actually met with a accident, where his original silencer was damaged..

Scratch off points #6 and 7.To put it simply,just ask the lathe guys to match the head with that of the bore of rtr180.
Forget about high-lift cams.I was just merely telling you what are the things which needed to be done in order to exploit the full potential of a bigger carb.Actually some are saying stock valves are ok and that there's no need to increase their size either.
The pic below shows the head and the combustion area and don't worry its not of a fiero. Just ask the lathe ppl to enlarge the area circled in red.

@nanotech

You are right ,if you put a free flow exhaust then there won't be any back-preassure so the engine will loose out on initial and mid range a bit.Which is where the engine needs power in city conditions.
The same thing with a bigger carb as well.I am going for a bigger carb so let's see how it performs in my set up .But i am sure initial and mid range will go down.
Regarding the silencer of the f2,why dont you guys go for the apache150 silencer, i know that the silencers are matched for the engines .But i think it should do just fine.

dude..
tell me 1 thing..
our engine's block is 3 parts..
the lower part, joined by packing directly to the engine..

the central part joined to the lower part with an aluminium gasket.
bolts are there here which help in joining.

the top part which is the head of-course joined by a paste..

now if i buy a apache 180's block..
will i get only lower part,
or the lower and central part?

because in my boring those guys took out both the parts the lower and central and bored it..
in apache's block will we get both of these as 62.5mm or only the lower one??

i am confused..

The three parts of the engine:-

3. Main block/bore-kit(RTR 180's which you'll be buying)
2. Head (which needs to be matched with the bore)
1. Head/cam cover

The block#2(57 mm) has to be matched in diameter with that of the block#3(62.5mm).
I've used the pic uploaded by remortr

yaa even i had this in mind, but picture cleared all the doubts.

thanks gixxer .....

so match the middle area, and hatch the head are too that's all that needs to be done..

it shouldn't take more than a day it seems.

@ vishal..

dude i can come this Saturday to get all the work done for my bike, i.e upgrading to 180cc..
are you free??

will your mech be free?

can you call up those carb tuner and porting specialist and ask the timings in advance for this Saturday..
because i believe there's a holiday so i doubt they will be open..

please let me know man, i am dying to ride a 180cc fiero...

@NANOTech

I enquired with Atul Scooters and he has the 180cc cylinder kit ready with him. It will cost you Rs.2375/- which will include the following:

• 1 cylinder
• 1 piston
• Piston rings & pin
• Gaskets

What we need to do is get the engine opened up.Take out the head & the cylinder and take them to the turner(lather guys). Buy the new cylinder head & take that also to match the size of the cylinder and the head. We can get porting done(if you want) with the same guy. This guy is based in Dadar and the carb tuner is in Grant road itself.

Everything depends on the turner whose going to work on the head. If he gives us the head back even in 2 hrs, we are OK with it. We rush back & ask the mech to start building the engine while we get the carb tuned.

But my friend, this saturday it is not at all possible, due to some reasons. First thing is it will be the second day of Eid, so mech will not be there. Plus its Ganesh Chaturthi, so the turner will also not be available. Thirdly(You are gonna kill me for this) I am going to Pune to enjoy the long weekend, so I will also not be available .

The week after that I will be in Mumbai and will be getting the disc installed on the bike. I have already fixed this with the mech and he has the complete day reserved for me .

I am also dying to install the disc, but something or the other comes up. Even I am desperate to ride the 180cc Fiero and "Feel the Difference" so I can understand your excitement too buddy. But maybe you will have to wait for another week or two to get things sorted out.

Till then happy riding & enjoy the LIGHTS.

@vishal

I think you just ruined nanotech's whole week.Yaar gagandeep ,i know the feeling man,i'm even more impatient than you are.The carb is getting delayed and i am feeling helpless .As i want to get the silencer job done soon and i can get it done only after seeing the affect of the bigger carb.

its okay vishal..
maybe next week ..
oops but you are already installing disk brakes that day aren't you ??

please please please try on some WEEKDAY next week or a week later as i am TOTALLY free on weekdays..
if you want I'll kill your office's server from my place and you'll get an off for atleast 2 days..

all expectations are from you man...
sorry to be a burden to you dude..

meanwhile i am enjoying the lights
atleast feeling good on SOMETHING..


and 1 more thing..
i read your bike issues in skype..
see your CDI is powered directly from battery, so whenever battery goes a bit down, there should be a slight problems in idling, but previously when your battery was entirely dead as we checked it, showing 11.1 volts, then it didn't have any CDI related problems then, so it shouldn't have any problems now too..

just see if it happens again sooner or later or more frequently, if it does, then we might check your pulse generator (black thing on top in the stator, who's screws are damaged) if needed we'll replace it..


@ gixxer.

hey dude, i am already working on the block, and i am waiting for your inputs on the bigger carb as well.
tell me one thing..

if in case i swap my carb to BS29 one and swap the silencer also to Apache RTR 180's
even the CDI of A180's to cancel out revv limiter..
than will the bike perform EXACTLY the same like rtr 180??
if we ignore the chassis and gearbox...

i don't plan to do all this atleast for a year maybe, but asking just for my knowledge..

eventually my 7 year old carb will give up, and as tintin mentioned silencers for F2 aren't available (which is the best thing i like on the F2) and with time it will give up too then i might have to do it to keep my baby alive..

sorry for interruption may i know whats actually going?i guess gixxer is going to fit 180,s kit to the fiero may i wrong correct me!

Thanks for adding some fuel to this . Gagandeep is already burnt now.

Ok....This happened just yesterday and never before. Today morning I just opened the battery side panel & thought of changing the fuse. The fuse box between the 2 battery terminals is the culprit here . I had a loose contact. What exactly happened yesterday was, while crossing the signal I happened to put my bike through the pothole & that is when it happened. Today again I checked with the lights ON and there was no problem . I need to change the fuse box today. Also can a 7.5amp fuse take the load instead of a 10amp?

The problem is I cant bunk office even for a day. Travelling season has started and my team member will also be on week's leave & then our team manager is on leave, so 2 weeks gone there. Still, let me try & see if my leave is approved, I will let you know. Please bear with me on this.

If you say this again, you are gonna get a kick from me . We are here to help each other, so take it easy mike.


NANOtechnology is planning to upgrade to a 180's kit. Gixxer is already running on a bored engine & using a ZMA piston kit.
