Just shot a hole through the 440 and now I’m looking for an entire new top end. Was a 440 kit with a stock carb and porting with a stage 2 hot cam. 11/1 Wiseco piston. I was looking at an 89mm 12.5/1 compression piston from Wiseco and a stage 3 hot cam. I need a new head and cylinder as well. What do you guys think would be a good kit/ parts list for the rebuild? Looking mostly for top end and a decent mid range. Most trails I ride are very rocky and slow, so low end doesn’t concern me much, but I do occasionally let it open at a friend’s house and may go to an Mx track sometime. Race gas isn’t a problem for me, so give me some ideas.
