but I have spotted a sound at cylinder head, suppose dat a wooden piece is stuck in brake drum and the periodic noise it will make when wheel starts rotating, exactly this kind of noise I have spotted at cylinder head.
when i asked tvs people abt this, they said this bike has roller bearings at tappets which make noise and gradually it will decrease. but I don't agree with this point..a bearing is meant to reduce friction n noise..
n secondly the tachometer pointer starts fluctuating when it reaches 3000rpm mark..can't figure out why these problems are there...
Please help me to sort out this..

N i saw many discussions in this thread that some bikes couldn't cross 8.5k rpm in 5th gear....how should i check this...is it ok if i raise the accelerator to full in such new condition?


That '69' 250fx is being ridden by my friend, KP (Aravind KP) for National Supercross Championship. Well, they are not carbbed and compete in the 'Foreign class' against the Hondas and the Yamahas. The Japs 've a little edge over the desis. Nevertheless, TVS MX bikes 're brilliant and above what rest of the jokers from Indian auto families can conceive.
The 160fx (Indian class) has the block from 160. And it can eat Impulse for breakfast, I reckon!
