Ya. I know about the 4 stroke air cooling stuff.

I thought about a whizzer kit. But too much.

Whats the diffrents between ebay engine kits. And the onein the bike stores on here?

Some of the sellers here have better customer service, like thatsdax. If you do a search, there is a giant thread about which vendors (here and on ebay) offer the best customer service....without it, you buy a kit that has parts missing, bad casting, ect. you are on your own.

Is that worth the 20 dollar savings?

Hi, u can get a slightly over bored piston & jug from Rock Solid Engines. They have been taken out to an actual 70cc, not the normal 66. They come in 3 different "stages", HP1,HP2 & HP3 & u get the gudgeon, clips, quality bearing, piston & jug. I believe the piston has properly spaced bosses 2 fit the bearing properly. HP2 & 3 pistons r ceramic coated (skirt). I recieved an email off Tony at RSE recently telling me not to order just yet as they will soon b releasing more Hi Perfomance products. Cheers
