In 2003 they(Yamaha) changed the swinger from silver to black... It was slightly different.
However, I have a used 2002 swinger in my garage.(which will fit your bike)
I bought it with the plan to change mine as a chain snapped on me and took some chunks out of mine.
As some thick car driver pulled out on me, i never got the chance...
Still have the spare one and I'll let you have it...
Make me an offer - and if you don't live close enough you can pay postage.
I have lots of other parts as well, Front Mudguard, Levers, bars, Screen, Original Exhaust.
Oh and I have a Haynes manual that may be of use to you as well!!!!
Drop me a line
