I was suprised how small it was and its the 80cc. Fit and finish is not the best but I wasnt expecting Japanese quality. I wonder why honda or suzuki or one of them dont jump on the band wagon and start making bicycle motors like these, sure they'd be twice the price but sweet as. Anyway its very cool, will change all the bolts to better quality high tensile, I'll use a good dirt bike twist throtle, and change the clutch lever to something better too. Pretty much all the periferals need upgrading. Unfortunatly my bike having 3 inch wide tyres the chain will never clear it. Going to buy an electra rat rod like in one of the pics posted on "my first 80cc" posting and fit the motor into that. Keep your knees in the breeze lads.
