Just wanted to see if anyone had done this and whether it is straightforward or not.
spoke to the guy selling them on ebay who says it will only fit on the s1-2 wheel or the 6 stud mota-lita aftermarket wheel. not a problem as have one of those already. I guess i just wanted to make sure that the standard aftermarket boss will fit all series, i.e same shaft thickness and splines - F1 style boss is ?350 and want to make sure i can retrofit it before i buy.
Also, is the s3 wheel a different stud pattern to s1-2, obviously the horn is different. (and i think the horn is the sticking point, in that the new boss only accepts the inserted horn button from s1-2
while we're on the subject does anyone have a s1-2 horn button for sale?
