Just the footpegs, or with the brackets too?
If you only need the pegs themselves, then basically any early Yammie ones will do the job - I have a spare pair of the correct pegs (same as D, E and other F models, if you're a train-spotter).
If the brackets are the same as D/E, then I've probably got a spare pair of them too.
Kick-starters are avavilable new from Speed and Sport ($$$), but if its a race bike, then new genuine DT175 levers fit straight on and work fine for ~$80 from you local dealer.
Don't f$%k around with the after-market ones 'cause they're rubbish and they're not much cheaper than genuine...
Airbox cover, I can't help you with.
