nope... ur wrong...

guess ur self...



^ giv u some clue ^

of coz lah... 

i use Disc type... 

yup.. Racing Boy Rear Brake System Ver.II

Depends on what type of CDI la. Mine BRT, forgot which one, if buy new one at sentul also i think max rm220 IINM.

However i can only feel my powerband smoothened by using this CDI, and some power rush (kinda like V-tec rush ) at higher rpm from 1st until 3rd gear. 4th gear not much diff.

TryX: Thanks mate. I'm thinking a Lagenda mod, cheaper bah. RGV not much spares or mod parts around, let me know if you know any. Mine is still thoroughbred stock loh...

Suhail, for long distance, I would prefer smaller rear sprocket. Reason being higher cruising speed at lower RPM.

In fact, I just stocked some chains for myself, O-rings and 428Hs which taukeh say good deal, just asking if any of you interested. Mind you, these chains are heavier, and need maintain every 500km.

Right now, pickup is very light, topspeed 140 at 8k RPM. So plan to change to smaller rear sprocket to bump up another 10~20kmh. Rarely full throttle, half at most, coz doesn't seem to benefit pickup, topspeed stuck at 80% throttle. My guess is the engine really has much room for improvement.

What's your current size, is it stock?
I would reduce 3~4 gear on the rear sprocket. No need to change chain if not loose. To test this out, tarik the chain that is around the rear sprocket, if you can lift it off the sprocket, the chain is loose.

use 15-37 or 15-36 if you always cruise on highway.
