[QUOTE="BigBore, post: 98247, member: 16143"] When I got my 650 home yesterday, I installed the following Power Up parts and mods: -Intake manifold -Carb needle (clip in middle position) -Removed snorkel and restrictor plate in air box Instead of getting the Power Up exhaust insert, I used a 2" hole saw and drilled out the baffle from the stock spark arrestor. Got that idea from here. [url]http://members.nbci.com/bhoth/nonepa.html[/url] The Power Up kit came with a 175 main jet. So I put that in. Rode the bike, and it was running way rich. It would really lurch and blubber when you'd back off the throttle. So, I went down to a 165.....a little better, but still quite rich. So now I'm down a 160, and its still acting rich. Any ideas? I wouldn't think I'd have to go any smaller than a 160. I thought maybe the air filter was over-oiled (there was oil running out of it), so I dabbed some of the excess off. Maybe I should just clean it and re-oil it correctly? Thanks in advance. [/QUOTE]
