On my 2008 F6 - sometimes when I take off or when I slow way done then want to accelerate, it will bog and sometimes stall. To get it going I have to keep butterflying the throttle then it runs fine.
first clean power valves may be sticking open then go over clutches check rollers first check spider any kind of binding.
if not all the time but getting worse those are good bets
This seems more like a fuel problem. I know the throttle lever is quit sloppy. When I hold the lever front tight against the handle bar it does not do it. But if I hold it back a little from the handlebar it does the bogging thing.
Could a worn throttle and handle or a stretched throttle cable cause this?
it would feel like cutting out if the throttle safety switch was engaging and yes with a sloppy throttle it would activate the sensor U can unplug it and see
