not to jack this thred but i have had a chance to take both the bikes out together.
first is a 02 same bolt on's as my RZ besides carbs, i ran 5 of them 450's a yfz, Z450 2 hondas and a kawi. the o2 came up about a bike short of them all off the line with a 2nd gear start and i couldnt pull any of them in i go to the trailer and get the RZshee now we all lined up again with a 3rd gear start and the story takes a change. the power the rz has it out in front of all besides the kawi and and they couldnt pull me in. the kawi we stayed together all the way down and every race before i got into it the kawi took first with them all. im running 30mm carbs and in 5th there drying up, the track isnt long enouph to get into 6th but i would think the rz would pull from them all up there if we had the room.
i didnt change the trans in the rz and went with a 12/41 gearing the o2 has 13/41
RZ has 30mm carbs with K&N the o2 stock jetting with K&N
RZ stock bore the o2 is 20 over
both are on PT mids and were running on a sand/dirt mix 32-1 on benol / 93octain and im 240lbs
next time im going out there one of the guys is bring a 410 banshee to see where the RZs at with it but i will have rockets, reeds, and duel pingal on there buy then. will take the camra also
BennBB thanks for all your help getting it here.
