I can comment on the "clunk" issue. This IS the nature of the beast on this machine. If you switch to synthetic oil this clunk will improve considerably. At least it did with mine. Also, it helps to "pre-load" the shifter when going from 1st up into 2nd. That means before pulling the clutch in, apply pressure on the shift lever so that when the clutch is pulled in there will be a positive shift from 1st into 2nd.. Good luck and ride safe!!
