RG125FUN '94 Piston Kit

Hi Guy's,

Paul Smeeton's Bitz4Bikez is advertising oversized piston kits. I think my bike is due a new piston anyway, was just wondering if I would have to modify the bike in any way to fit the O/S piston (2.00 I think)?

Another problem I have with the bike is, in 1st and 2nd gear, when I pull the throttle back, it reaches 5k revs, sputters for a bit without any accelleration, then the powervalve kicks in and flies like stink. Could anyone advise what might be the cause of this?

Thanks

I dont have a clue if its been rebored or not because its a jap import full power model. If it isnt, how much do you reckon it would sting me to have it rebored?

The spluttering could be caused by:

wrong mixture settings, (wrong needle position, leaking float chamber, clogged air filter)

Powervalve not set up properly

Anything else out of the ordinary

Apparently the spluttering could just be a flat spot from the guys in chat.

Another thing I noticed is a funny grinding noise when I'm in 4th gear. Any ideas?
