Today my son apparently shot a turn wide and went down on our white 919. Tough getting that phone call that starts out "I'm ok"... Best news is he is a little sore but otherwise unscathed. Wearing his brand spanking new AGV helmet he just bought yesterday! From what I can tell he managed to keep it vertical off the berm, down through the ditch and finally lost it in the field where it low sided until it grabbed then it flipped over onto right side.
No easily visible major damage--We hosed lots of dirt off the left side. Windshield got ripped off and left mirror glass is missing. Chin spoiler is cracked. Sliders might have saved the bike even in the dirt.
My question is he said when he picked the bike up the shift lever was around vertical from the normal 9 o'clock position and he bent it back down. the rod has an arc in it. any chance of internal damage to the shift mechanism? I didn't want to try and ride/shift it until I give the bike a thorough going over in the shop. Bike started back up ok and ran. I trailered it home.
Thankfully your son is OK, that is #1 by miles from #2.
As for the bike...................
Suggest you try to dial the shaft of the gear shift spindle right behind the outboard splines that are for the gearshift pedal link. (Unless it's so visibly bent you can easily tell)
Do it at a couple of points, through as much travel as you can get from the spindle.
If it's good to go in terms of indicated runout, you can relax.
If the runout indicates a deformed 'spindle, then it needs to removed and adequately straightened or replaced.
The bent rod between the links can be straightened or replaced. (if you try to make one, you'll need a left hand die for one end).
The shifter pedal (lever) being a mild steel fabrication, can easily be straightened.
