I'd like to see what you ppls can come up with as in why when I'm cruising in any gear, but more noticeably lower gears, my bike will buck severely at light throttle where I'm trying to keep the bike rolling. It's never been this bad, and recently gotten worse. I've b;amed PCV for this before as i have removed my previous one and bike seemed to do a whole lot better without it, (it had idling problems as well) But I got it replaced under warranty, however problem has returned. It has a custom tune that's been good for a few years. It's really bothering me, I have gone through 2 sets of plugs, vacuum line checks, chain adjustments, nothing seems to help.
