... when you say you're looking for parts for your old bikes, it sorta depends on how fine a point you want to put on it....
For common British bikes (Norton Commando/Atlas/Domi or Triumph/BSA twins) nearly every part to keep the thing going is available either NOS or as a pattern part.
Same for Yamaha two stroke twins (TA, TD, TR , DS7, R5, RD, RD-LC, RZ, TZ 250/350/400 )
Same for Ducati narrow case and wide case singles, round case and square case twins, (but the Ducatista is very cliquey and seem to have deep pockets) (The next series of Ducatis, the last of the Taglioni bikes, the early belt drive 900SS seems to have fallen into a void. There is almost ZERO support for parts, literature and practical experience. It is really weird)
Same for Guzzi round or square heads. Seems the Papal police still use T3 Guzzi's so all the hard parts are easy to get and comparatively cheap.Last year I bought a new, "made in Italy" top end for a 1978 T3 (2 cylinders, 2 pistons, 2 ring sets, 2 wrist pins and gaskets) for $800. If you're looking for a pair of concourse floor boards, or front crash bar for a T3? You're probably not going to find one.
... I can keep any of these bikes safe, running and reliable, even in hot rod form
BUT if you're looking for an original left side cover for a 1978 Yamaha Canadian 3J7 model RD400 you're SOL (The Canadian one was different that year).
Or if you need a crankshaft for THAT bike you'll have to talk to me, AFIK I'm the only one that rebuilds that crankshaft. (cue maniacal laugh here)
There's no pistons for the air cooled Yamaha's, but we all know how to modify Banshee quad pistons.
I'll tell you it's pretty easy to keep most "popular" vintage bikes going/running/safe/reliable, back to the late '50s , early '60s bikes. The problems arise when we start calling them "collector pieces"
Maybe it's the people I associate with. We're all vintage bike hoarders.
When you start talking about more obscure stuff, this all goes out the window...
I've been looking for a pair of mufflers and a right side cover for a 750 Laverda, like the bike Evil Knevil used to ride before he was sponsored by HD, for a few years now.
If anyone had any leads on that.....
