Thanks,Duck!Well,it is a good bike,but old-looking due to the abuse I've dealt it.(probably more than 11,000 miles on the bike)If it runs really well with this kit I may put a `mirage' paint job on it like MADDOG and STEELTOAD speak of.The kit from Polini came with a reed valve,so low-end power should increase,and that is what I want.When I removed the old piston I checked the rod bearings and they're perfect!The tranny gears are perfect too! The Cosmo Colt I got the engine from only had 200+ miles registered with speedo broken,and I'd bet with my 2000 or so the engine-tranny has little more than 4000 miles.It has needle roller bearing sleeves in both rod ends.I replaced the wrist pin bearing anyway with a new one.I ALSO changed the front sprocket to 13 teeth(it was 12 tooth).So I should cruise at around 35 mph,no problem.How ya' been,Duck?Is your moped running good?I forgot what kind it is.Tell me about it.(:^)
