reboring one clylinder out of 6

[hookless]

On a rebuild if you only bore the bad cyl to .030 and leave the others standard will the engine not last as long as if you made all 6 .030 and balanced. I have seen some engines with only one cylinder bigger than the other and was curious if it had a shorter life. Thankyou for any input.

As long as the piston and ring assembly of the bored cylinder weighs EXACTLY the same as the rest, it will not affect engine life in my experience and what I've heard.<br />Good luck

I read something a while back that if all cylinders are not bored the same and one is over it will not last as long as a balanced standard sized engine

With todays 2 stroke pistons all sizes are within OE spec as far as weight. It is perfectly acceptable to bore one larger than the rest.<br /><br />Now we're talking weight here -- not wear tolerances and cylinder size. That was the question - weight.
