What are you in need of walshy also state condition that you require the part to be in (for the benefit of others).... I dont have much stuff for an F as i gave it away when i sold mine.

Hey Brett, I'm starting at the front. I need a front brake shoe plate, front axle, spokes kit ,cap/air valve to top of forks and handle bars. This would get me a rolling frame to get started. The condition I am after I guess would be fair to good? So long as they are complete.I'll be looking out for a motor as well. If you can piont me in the right direction I would appreciate it. This is all new to me!!
Regards ,Steve

Are you going for a proper 100% original resto, or a ride bike?

The basic motor was only used in 1979 model YZ250/400, and 79/80 IT250/425, FWIW.

Front spoke kits are almost universal among Yammies of the era - everything that had the 322 or 1K7 front hub uses the same spoke kits.
Front brake plates are much the same. Any single leading shoe YZ/IT brake will work, providing its from a bike with a conical hub and leading axle forks.

For the 'bars, passable copies are available if you look around. Originals are rare, but you shouldn't have to pay much if you find them. For a ride bike, just get some 764 Renthals and be happy.

Walshy,

Seeing that your at the roller stage, Make sure that the bush in the rear brake backing plate spins inside the housing cause if it doesn't then the rear suspension will not work. This one got me stuck for a while... Also look at casting marks (numbers) on various items. some may be passed on from previous models (i understand that yamaha did that a bit) but be careful with certain components like the cylinder etc..
Have you built bikes before? There is some real basic step by step things as you pill things apart or assemble. Manuals will tell you some stuff. Guys here will help a lot.. I know of a link to show diagrams etc on a fische. do you need this?
 
Nathan knows a great deal about yammies.

Best assembly manual for any bike is a parts manual!!
