    525xc bogs on full throttle when on low speed in high gear

    Need tips:
    The bike ran great until yesterday: if you hit the throttle when in too high gear the bike just cuts out and dies, if you don't release the throttle and shift down. Any ideas what I should check? Can it be the valves that need to be set? The carb is now out of the bike for cleaning, maybe thats the problem, but I doubt it.


    Update: the valves were conpletely off, adjusted them, added new carb lines, cleaned the airfilter, checked the carb to head boot. The first run it did hasitate a little when in low speed and high gear, second run it was much better. Couldnt try so much more because the rain was pooring..
    Dirt in the tank maybe?

    setup: 525, 43.5mm carb, FCI intake, ktmbillpipe.

    If the carb cleaning doesn't fix the problem then do a leak down test to verify the valves are not cupping and the rings are still goood.

    Mine did that when my carb to head boot was cracked. I didn't see it till I actually bent the boot then I seen a small crack. If your sure its good the double check the tps. Also whats your carb set up ... leak jet, main and pilot jets?
