hey there i have a 07 rev 800r that i bought from my bro that put a 860 SHR kit in it... my first trip out on the second day it blew up lots of fun lol, so i had the engine replaced for it was screwed.... now i know the gears have changed(i have the stock ones) and the clutch well it is not stock, i have about 14.9g in it now but not sure what stock is and i am trying to get it set but having problems, jetting well i told them to put it back to stock when they put the new motor in they are 470..... i have been trying to get info on this sled but noboby wants to talk about them.... i think i am going to the dealer so i can get a book on jetting and clutching for this sled.... awsome sled though..
