Pictured is my 83 xs. It started out riding it 7 years ago as pictured fully assembled. then 5 years ago I decided to take it apart and rebuild it right to my liking. It wouldn’t go over 50mph before guessing because it had stock jets with pods and straight pipes. It was on pause because of life in general. But now I’ve been working on it. Repainted everything. Rewired the whole bike. Now I’m at the point of rebuilding the motor. I’m stuck on the idea if I should order the 750 kit from mikesxs or just rebuilding it as the 650. I’m already set on carb kits from reading the posts on here and knowing who I’m going to get them from. The motor now is bone stock. Never been bored. But the pistons definitely look like it had a long life in this motor. So what are your guys opinion on what route I should take with this engine rebuild?
