first of all, I'm not really looking for an aftermarket swingarm. I'm just looking for something a little better than the '85. I'm on a pretty tight budget right now. I'm looking to set the bike up for handling, not dragracing.
I was thinking of one from a newer gixxer or even a kawi or something. anything that'll fit.
do a search over the last 60-90 days and there are lots of posts on how to mod the early bike for a later swingarm it ain't a direct bolt on you have to make dogbones and a bushing, as to the shock a fox or works, or custom machine to adapt a later gixxer shock to the earlier style which is what I did, as to the effectiveness of the mod it is the best mod to improve the handling of an early gixxer. Mine doesnt get blown around on the freeway anymore and it doesnt weave.
