If you put the 14 or 15 teeth gb sprockets then you wont be able to pop wheelies in front of collages. which i think you will miss!! That's why the suggestion to revert back to stock in cities.

What happened to your "goon-bike" plans?? knowing you ,why don't you convert your f2 to a "goon-bike" replica ??

That's ok buddy-I'm not into that anyways.
What I wanna know is will it cause any harm to the engine on a long ride?

I have converted myself into a goon-that's inexpensive&even better!

Yaar what a downer i was looking forward to seeing you ride that "goon-bike" must be something eh?

No it will prolong engine life if you make the gearing taller,but it will loose all acceleration if you go for 15 teeth that is.I think you would be able to manage 14teeth one.

How many teeth on stock?
I will go through the sprocketing threads&call you in a few days time.

Stock f2 is 13/40. Yeah go through the sprocket thread.

Totally no hope of "goon-bike"?

bprags's posts are giving me a tight scare...

however my new bore has run 5000 kms, and have done a 478 km tour too recently, had no issues, but i would never wish to have a problem like that...

i am having knocking issues on sudden throttle opening, what should i do ??

i already have an extra gasket as you all guys know, should i go with Vishal to the bore guy and get the issue sorted ??

i would NEVER want to have any more issue with my engine atleast...
what should i do now ??

Nano have the patience to read the earlier posts...I had requested you many times to measure the compression ,and also to add one more gasket since you have a run on of engine at 8K RPM.Your piston and bore are getting ready to commit suicide....you decide what you want to happen to your bike .

Instead of adding 1 more gasket and allowing more oil to leak from the block base (as in my pictures), isn't it better that i rather work on my head, finish the issue once and for all ?
i am somehow not finding this gasket thing soo reliable..

In my previous visit to a bore guy, he explained me all the ill effects of modding my head, proving that my current head cannot be modded in any way.
so i would now go to a different bore guy, the same one who worked on the valve recesses, and ask him to work on my head, since I'll tell him that even with an extra gasket, it still knocks. Maybe he'll understand what to do....

and i might get my head ported too...

isn't this a better solution ?

since you were reluctant to do the head,I had suggested the gasket as the stop gap solution to prevent a disaster.If you can do the head mod,then additional gasket not necessary...Always take a compression reading and keep it within recommended stock spec.
I hope you remember Bprags posts on this

Nope, as gixxer said, If you make your bike taller geared you will achieve more speeds for specific RPM"s, so by putting 15t for eg you can do say 80kmph in 5k rpm which you will achieve only @ 6k rpm

This sounds great man! 80kmph is something that I cannot sustain for more than 10-15kms.with the current setup-the engine will be overheated very soon.
But is this as good as it sounds?
If not, then why don't they make the stock bike like this?
I will go through the Sprockets thread&also discuss with you guys. Lots of time left for that.
Are you talking about changing only front, or front&rear sprocket?

Companies decide on sprocket after taking in to consideration after lot of other things & I am sure our's ( biker's ) will be the least to be considered.

Now coming back to topic, You can either change only front or only rear or both,that can only be decided only when you know what set up would you want for your bike & the comparabilities available.

Classic Fiero set up is 13/39, after riding CBZ for more than 9 yrs I felt fiero Initial torque is just too much for me to handle & it lacked for me in High speeds, i.e to say I felt less power in higher rev's & what I did now is by putting a 14t front sprocket Spread the power more in to Mid range & High range compromising on the Initial.

Fyi, I did all day long 80, 85 & sometimes 90kmph in my fiero on my recent trip to vellore & it felt butter smooth through out the trip & my breaks frequented as long as 100kms between each.

I finished a total of 465kms in a span of 11hours with 10-15Mnts break & one long break of 1.5 hours in Vellore

Now in your case you can go for 14t from yamaha Crux which is a direct fit & i am using it, and for 15T you can try from RX135 which Gixxer used for sometime ( I am not sure if it was from RX 135 or Rx 100) Gixxer can confirm on this.

With 15t you will have to loose a lot on Initial, but Highway riding makes life much easier with achieving high speeds @ relatively much lower RPM's

Cool! This is very informative!
So I will speak to you guys soon!
Thanks!

@ all

I have a query, my TVS fiero Classic 2002 model.

for the past 6 yrs my fiero is with 100/90-18(MRF zapper Y ) on Classic pulsar 180 Rim.

I am planning to get back to 3.00x18 ( stock size) since their isn't much space after putting 100/90-18 & also removing the tyre for fixing puncture is a tedious task.

I was wondering what are the advantages or disadvantages of putting 3.00x18 on classic pulsar 180 rim,

I managed to see what is the rim size & all I could find is 2.50x18 - I am not sure if this is the exact rim size.

Pour in your thoughts

Guys, I am currently running a 13 / 40 setup ... did not know anything about sprockets and its effect on the gear ratios and speed. Just bought whatever I got ... Insisting on Genuine!!!. I suppose the guy gave me F2 sprockets. OEM, Genuine TVS etc were written ... so I bought it. Did not even bother to count the teeth until Gixxer told me.

Feedback..........
I guess the initial pickup has not dropped as it still has 13 front. I have also not tested the bike to the max speed with this setup... I feel cruising at 80+ will not be a problem. It's just that the chain needs tightening visits to the mech's every two week or so ... though the frequency has dropped now after readjusting and tightening the front sprocket.

Requesting your views ....
What can be the outcome of a 40T rear? drop in speed, effect on cruising etc... I have no idea.
