Around 40 I think. The top engines are making closer to 42hp. Is that what you were after?

Yea 40hp would be assuming everything running perfect and in good conditions (cold, clean air etc) so 33-35hp is probably more accurate

Fucking heaps. I got to ride one after the guy who owned one couldn't kickstart it, so I got to use my wicked sick bumpstarting skills. Man that thing has got some grunt. What a laugh it would be in a roadbike.
