drop in rpm

[Cerius]

Hi guys, i've recently changed my piston, sprocket on my krr150. And i've noticed that my speed is heavily reduced. initially it runs at 100km/h on 6rpm, now i only runs 90km/h at 6rpm.

 

I wonder if anyone here knows what problem? Or the piston still needs to be run in 1st?

 

thanks in advance...

Bro if I'm not wrong it has nothing to do with ur piston. It is your gear ratio set-up that affects your revolution of ur wheel which affect urs speed. Juz my 2cents

is ur spocket la.

if u only change the piston/rings alone and not change the gear ratio,

it could be worn clutch plates.

So CLEVER ! lol. its your sprocket lah. you changed the size. small for good distance use, big for stronger pick ups.
