Has anyone used the 88 kit from Sterdy Products that just changes the piston and cylinder? (not the kit that changes the head and carb and more) I have a 70 with low compression and just wanted a cheap way to get it back up to par and maybe have some extra power. I do not want to build a rocket; I have another that I am going to building that is going to get a big motor. Or what other ideas do you guys have?
Thanks

It is the 88 bore up kit, well worth it for a 100.

To get the best results from a 88cc kit a new or rebuilt head and a new bigger carb is needed in my opinion and also maybe a change in exhaust from my experience.

Can't speak to the kit you are looking at but I have put the full 88 kit with the head carb clutch oil pump and I am very happy with that. Able to gear it up and still have lots of power. Working on a 125 conversion now and will post about that after the holidays.
