It's a 79' YZ400 with a 3mm big bore. 85 bore x 75 stroke = 426cc
Mods:
Full DG exhaust
Lightened flywheel
Flowtek porting
V-force reeds 3- yes Moto Tassinari made them for me.
milled head
polished exhaust port
race gas
Like most I'm just wondering???
thats just a guess, i figure its a older model and but still a big bore, the newer 500s were somewhere in the 50-60 range so i would say somewhere in the 40s, maybe 50
very cool blaster, looks like a sleeper Im sure you will be able to hang with stock banshees and 450s, but i doubt piped shees and 450s...still very sweet ride. Im sure it is somewhere in the mid to upper 40s hp, are you happy with it?
I built this entire quad for the price of a good 450 exhaust
I ride with a friend who has a wolverine 350 and while he's bangin gears contantly on the trail I just keep mine in 3rd the whole time.
