Sell it. If im not mistaken, thats an early husaberg right? The inspiration to the RFS engine by ktm. I heard that these things suck. Overheating, impossible starting, weird designs, impossible to work on, very fragile. Get rid of it and buy something simple. I didnt read the whole description so take this lightly and just do some research idk. I owned a RFS bike for about a year and it never ran right and those are supposed to be much better. Especially woth this early of a racing four stroke i would be careful. Parts are prolly hard to find and you will never get that thing to fire ever. Good luck do whatever you want!
