the factory kit complete with derestricted manifold, lighter rollers, and a new jet came from the dealer for $150usd. You should have no problem getting that from any CPI dealer. You can find boost bottles on ebay...there are some crappy/ill fitting ones on there so be careful. I have a really knowledgable guy I found on ebay working on a direct bolt-on bottle including manifold...when he finishes I will post the info/link on here for you if you want. as for the rest it was free..just removing stock parts. when i mentioned weight I didnĀ“t mean scooter weight I meant roller weight...you say you hit 1100rpm, I max out at 8500rpm which makes me think I could use lighter rollers.
