[QUOTE="Huck Fonda, post: 315697, member: 9687"] Adam, Most likely, that first time it jumped may have been because the gears weren't fully engaged. The shift fork was trying, but if the gear didn't slide over all the way due to a heavy load (got bound up as you were applying throttle), it already had some pressure on it. You say you got it up to around 7k, and without a dyno chart I can't be sue, but that's pretty close to peak power. When you got there, that gear that was only partally engaged jumped out and back in (the dogs "jumped time" once), putting a ton of force on the shift fork that was trying to push it all the way in. Make sense? That one event could definitely bend a fork, which is why you feel the "jump" more frequently now. The sift forks are designed to slide a gear, not really push one, or to hold gears in place. [/QUOTE]
