Hey guys I need some help if you guys can, I did a search and what I was looking for did not seem to come up so I am making this post. I just put on the CFM airbox/intake for my 04 ds 650, it had dual K&N filters, I also have a hmf slip on pipe, as well as big gun cdi, this was my first time riding the bike with the cfm airbox and my jetting seems to be off, I am currently 1 size over on the main jets with the slip on pipe, I was hoping I would not have to rejet, I pulled the plug off this weekend it looks to be fine, the quad overall runs good right now but I seem to have a miss/bog on during low rpms, quad runs good when reving up, any ideas should I jet higher? any help would be great thanks!
