Yep, you'll need to :-
Blank off the clean air then swap rocker covers
Swap generator and pickup
Swap gear position/neutral switch
The oil cooler doesn't fit with a few exhaust systems, if you blank it off (Yamaha sump plugs
remove the restrictor from behind oil filter.
Swap thermostat housing (from memory) as temp switch is different and stat diff temp.
Oh and an M4 system won't fit as sump is deeper and it fouls on cooler blanks so def can't run cooler.
