I would like to start a "Problems" thread for the '08 R1. Correct me if I am wrong, but we can not create sub-forums; only threads. There is not a sub-forum yet for '08 R1 mechanical issues, (or if there is, I somehow missed it).
So far, after doing some searches in this forum, these are some of the problems that '08 R1 owners have mentioned. By the way, if I accidentally picked up some '07 problems, it is because most of these guys are currently posting in the '07 Mechanical Problems area.
'08 R1 Problems:
Stalling, misfire, throttle-lag issue, still there on some '08 units, even though problem was supposed to be corrected with updated ECU/ECM.
.
EXUP Valve malfunction.
Bad valve guides.
Mystery "check engine", overheating, engine code light illuminates. Owner takes bike to dealer, dealer clears codes, dealer says nothing is wrong, code/light comes back shortly thereafter.
Unexplained ticking noise coming from engine.
Clutch rattle.
