Shifting Issues
My bike shifts great going up throw the gears, but on down shifting, I feel allot of resistance in the shifter. Are others feeling the same issue?
I have issues with metal slivers getting caught in the shifting mechanism inside the engine causing it to hang in gear. The dealer has the engine almost completely apart on the bench but could not find the reason why or where all the metal slivers are coming from.
I told him that when downing shifting that the shifter feels much tighter than up shifting.
Curious to see what others are feeling when shifting the 14.
P.S. Shifting my buddies' new generation Busa is like butter both ways.
TIA

I've never had an issue with shifting. Actually now with 56,000 miles on the clock she shifts better than new!
I can barely hear or feel the 1st to 2nd engagement. The rest of the gears up and down are the same and effortless.
Sounds like you got a typical flat rate mechanic that is overlooking something.
I think you might have a bent shift shaft or could be a defect in the engine cases themselfs causing binding.

Due you have first hand experience with a bent shift shaft?
Sounds like this could be a issue if one of the shafts is "out of sycn" with another one.
I guessing that one shaft must move to release/engage a gear and the other to engage/release the other gear at the same time.
Thanks for the info.

Yes I have had my experiences with bent shift shafts.
Most have been been because the bike got tipped over and fell on the shifter or was in a crash and bent it that way.
It goes unnoticed mostly cause you need to completely remove it from the engine and inspect it.
Even if its a small bend it will cause what you are describing. And it could have been bent leaving the factory.
