Hey, i just bought this 2007 Yamaha R1 and noticed there is fault codes 11, 18, 33, 34, 35, 36. Can anyone tell me if i should contact a lawyer and raise my purchase. Its a vibration noise at 3500 rpm and struggles with acceleration below 4k rpm, which i think is normal, but these fault codes has me worried.

What do you mean by struggles accelerating below 4K ?? I know they can be a bit weak at the lower rpms but they shouldn’t struggle by no means. I’d take it and have it looked at depending on what this vibration noise is??

Struggling by stuttering alot like the engine is working extremely hard and vibrating alot. Above 4k rpm its fine and has alot of power. I noticed in the diag the throttle goes from 15-97 and its supposed to be 16-99. Would this cause my issues? Also the idle is very rough bouncing up and down from 1250 to 1000.

I just cleared all my codes and they have not returned...hoping it stays that way. Currently thinking my issues would be fixed with syncing throttle bodies, but the struggle under 4k rpm has me worried.
