My bike bucked like this too. When purchased it had been sitting for a long time. The bucking had nothing to do with clutch adjustment on mine (leaking clutch pushrod seal was the first repair I did)it was impossible to pull away smoothly and my bike only had 30k.
Worn cush drive, chain and sprockets, clutch basket plus dirty injectors and poor state of tune all factors I believe in my case.
I’d do the Werks basket and pull the injectors and have them rebuilt, pull the tank and do the filter bypass and external filter mod first thing on these bikes then you’re not chasing your tail.
I bought a ultrasonic cleaner and my friends have all pulled their injectors and cleaned them, all amazed at how much crap comes out of them. Any injected bike I buy in the future I’ll clean the injectors first thing from now on.
Sitting bikes always have a small amount of water in the tank and worse. The tiniest bit of water will exacerbate these symptoms and go away after the bike running for a while and reappear after cold start.
Off idle poor fueling, sudden varying torque inputs and my bike was a chuddering, bucking mess.
With the Werks basket and a tune it’ll feel like a completely different bike.
