Re: husaberg fs 570 "project"
Mate, the engine is the sum of its parts, just sticking a big TB on it will not magically endow one part of your power band. Cut a hole in the seat and get the 450 map, if you go the big TB route you need the other engine components to compliment it, like the worked head and fat cam. I learned this the very expensive and hard way. If its a wailing top end you're after maybe a jap 250 is the answer
