drr 90 horsepower?

[newblue]

Pallpark guess what does a drr 90 stock have for HP?
I am putting a dirt bike motor in my sons and was wondering if I should use a 65cc or an 80cc. Thanks

Bound to be some old dyno runs around here, but I would imagine tune 2 stroke 65 or 85 would be more than the stock cvt engines.
More importantly what can the rider handle?

I tested an 06 or 07ish apex 90, it had 10 hp at the rear wheels.
