Message: [QUOTE="dre10dancer, post: 694498, member: 42789"] Here's a question that is so simple, you must know the answer. But I don't. I installed a Boeyeson Rad Valve and FMF system on my KDX220R. I went from a 145 stock main jet down to a 138. It starts fine, idles fines, revs fine ---except: It stall when the throttle closes. This can be a real bitch on a single track downhill into a turn. I'm sure that its some simple little thing that you've seen before, like needle height, or pilot jet or whatnot. If you have seen this with these mods, please let me know. Thanks. Andrew [/QUOTE]
