Wow !!! Doin' a billet 2 stroke. Schweet !
Ahhh, it should do more hp than that. You sandbagging ?
If port timing and exhaust pipe is done right you should be 190+ anyway.
My wife's Polaris 600cc has 125hp at 8100.
My stock Polaris 855cc has 149hp at 7500 on 89 octane fuel.
Here's mine doing a rip down my lake.
