ummmm since when did they make a high compression piston for a 2 stroke? :eek2:

i really don't know much about two strokes so i figured to run some vp110 you needed the piston:confused: what do i need to do then?

To run race gas and it be worth it, you'll need some heavy port work and your head milled down a good bit. IMO it's not worth having a bike that runs on race gas unless it's strictly a race bike. I've had bikes that ran on race gas and it sucked sometimes. You couldn't just go ride them, that was why I had to have a practice bike.

I got a good price on a 55gal drum on craigslist of vp110 and I need to rebuild my motor so i figured i could run 50/50 with it and I live close to a vpfuel dealer. what mods to make reliable?
