stock sleeve boring

[mcleod]

how much can be bored from stock sleeve before need to be re-sleeved?

much of the brand does 96mm piston when stock bore in 04-05 if 94!

i found only one decent brand that does 95mm one! but compression ratio is not what i was looking for...

i was just wondering if 2mm overbore can be done to the stock sleeve?


thanks

None, if u bore the cylinder at all you need to get it replated with nikasil.

Theres tons of available 94mm pistons out there for the 04-05 bikes. From what I've seen there is more pistons out there for the older bikes then the 06+'s.

Any distributer for CP or JE should be able to get u any compression 94mm piston you want.
Boring and replating a stock 450r cylinder normally costs as much as a new cylinder.

ok then! i know there are some 94mm that have nice compression, i was just thinking that we can oversize the stock sleeve like a 400ex !

mine doesnt burn oil, but i need to open it for the crank/rod !

thanks for the info, im going to stay with a 94mm
