Well, Saturday, I took my ped over to Matt's house cause he has the rack to mount peds on for maintenence. I took off my stock cylinder, piston and head and swapped it out. One major problem though...The piston doesn't work with my crank shaft. The diameter of the piston rod is too skinny for my crank shaft, hence lots of play, and no worky worky. So...I decarbed my stock piston and cylinder like zippy suggested, and put on a new base and head gasket. Now my Grande is running perfect. Plug chops are golden brown, and it is topping out around 33ish. I guess it was all the carbon, and the fact that I previously had no head gasket, causing a major vacum leak. As for the kit though...I am kinda pissed that the piston doesn't fit. Any suggestions on how to make it work? Or am I doomed to buy the malossi crank shaft to go with that piston?
