I’ll give the background information that could be seen useful. Ducati Dealer did chain and sprocket 3 weeks back. 2 days ago I let my brother take my bike out for the day. He doesn’t ride sport bikes and has some dirt bike experience and i didn’t really want to let him but I did because what kind of brother would I be if i didn’t. Keep in mind, bike had no issues at this time.

Yesterday, I take the bike out, first thing i notice is about 3 times on a 15 minute ride my shift lever gets stuck while using the quickshifter. It worked about 95% of the time, but that threw me off. I rode a lot that day and it was about the same all day and it progressively got worse today and I’m mad that this is happening. Can’t get it looked at until july 5th. Any ideas?

Edit: old owner did put some sort of aftermarket part on it to stop it from having false neutrals. worked great, not sure if that can contribute
 
Check over the bike left side closely. Sounds like brother may have dropped it on left side to bend/bind the shifter…
 
What do you mean by stuck? The lever is getting physically stuck in the downshift position or that the DQS isn't working on downshifts?

Not in the downshift position, DQS occasionally isn’t working on upshifts, but when I say not working i mean it like there’s a bolt completely blocking any movement upwards. it didn’t budge at ALL. pulled clutch in, works okay.

Thanks, i’ll take a look. bike definitely wasn’t dropped hard if anything, but i’m gonna see if there’s any signs that it could’ve gone down in the grass or something, and i’ll ask him if he hit the lever on anything. I feel like everything he touches, he breaks 😭
 
Yeah, that’s the unfortunate truth for many with siblings, as I have/had the experience
