jonny500:
when i put my piston in the bore it feels very lose, is this a forged piston or a 500 thing. i have loads of experience building 2stroke motors but never used a forged piston or built a 500 (they just not very common over here)
kaw rider:
I would measure the bore and piston to be sure what you have.
Motorrad:
I always check the work of the plater bore etc,..
Not everyone has a bore gauge.
You can kind of fake it with those feeler gauges you have..
Not the best and most accurate way.. But better than closing your eyes and slapping it together...
jonny500:
yeah i think you are all totally right. i just dont have the equipment to accuratly measure it here. i can take it some where to have it done, i think i will do that as it better to be safe. this thing has cost alot and i plan on keeping the motor for years to come, i will just keep puting it in newer frames as they come along.
