I bought this kit because it was cheap and I was heartbroken that my 50c gr1 kit threw a circlip. Little did I know this thing is a serious blaster. Just as fast as my Gr1 Kit but way more power all the way through. Close to 2k miles on it and it still rips, never seized it even though I was running it at 425-450 degrees WOT for months and months and months. Only reason I gave it 4 stars and not five is you gotta use a few base gaskets, I believe I have 2 1mm gaskets under it to get exhaust port right. Oh and my break in on this was just build it and rip it, dont be like me. Break your kit in proper.

Product pics are old, pistons are dual ring now. I thought polini W had big transfers, humngo. Its honestly not fair what these things can do.

i suggest weighting your front forks or rims with cool bopper toys like bells, cup holders, maybe some spikes here and there.... (just to keep the front wheel down) beware of bumps, i pop up like a street bike!~ took us 3 gaskets, indexing plug and got a windscoop to lower surface temps below 200* from 350*'s Friends all knew this day would come, eat my dust! 2 days delivered... WOW! Who cares if it seizes one day, it puts a huge smile on my face.
