Rm250 67mm bore?

Hi guys 

Any of you ever  just bored a 2 stroke cylinder 1mm  and just bought a 1 mm larger piston?  

How would that work out. how  would it hold up.   Its a rm250 2006. 

Thanks

Can't do it, your cylinder is plated.  You might as well go with either a 265 or 295 (300) kit.

Both 265 and 295 kits are very good, it just depends on what your looking for.
