450r bogging

[DEVINF450R]

I have an '05 450r that just now started bogging all of a sudden when I land a jump that is over 40-50' and has a "hard" landing. It is those types of jumps that you are on the throttle when you land soo I don't know if that is where my problem lies or if it is a hard landing?? :confused:

oh and I have not changed anything before the problem started except for an ASV clutch lever, and a new kill switch

Run the petcock on the gas tank on reserve, this seemed to help a lot with ours.;)

this is a bad bog...like make landings really hard. it wasn't normally there...actually it is more like the bike cuts out.
