I doubt you'll notice any difference. I've run both one ring and two ring pistons in mine (an '89) and couldn't tell any difference beyond that of having a fresh top end.

ok then buddy thanks for clearing that up for me, just waiting on my flywheel rotor puller to turn up so i can change my main crank bearings. then fit new seals and gaskets and torque her all up lovely job.

I just googled Mitaka pistons because I never heard of them and I have found that they are made in Taiwan and that they have relativly short life span. This doesn't mean that you will have problems, but I am cautioning you as to their reputation. I also found that they are the largest European import of parts and gaskets.

Good luck.

Do you plan on running MX with this bike or just running through the woods?
