Hello new to forum I just picked up 3 tri-z thee all baskets cases but pretty much all there gonna restore one.Just wonder about parts swing arm bearings wheel bearings stuff like that. Also can the cylinder be bored.

[muthey]

the cylinder can be bored up to 70mm and the bearings are available for a fair price on ebay and for a higher price from you local dealership.

Non-cracked clutch covers are very hard to come by. If you have a good one, keep it that way by replacing all the screws with allen head or hex head screws, torque them all evenly and to the correct spec, and use a proper gasket, no rtv! Also, there aren't many modern front tire choices for the '86 model 23-8-12 size.

Thanks i'm still kicking it back and forth on rebuilding one or parting them all. I work at a powder coating place so paint not an issue.I know how to do all the work. I it would be ashame to let them all die.

I remember going thru ebay looking for plastics for my Honda and seeing some yellow fenders and such for your yamaha. How are the plastics?

[sreiley99]

not good was gonna toss those and buy new

[sreiley99]

i'm not even sure if there 85 or 86 is there a differents

[Yamawheeler]

Don't throw older fenders. Use as extra fenders. When bashing through gravel./ gravel pits and mud and winter. New fenders show piece. Or dessert, fields, sand / sand pits. No difference in 85 86. From spec website that is.

Got any pics of your basket cases? We like pics. I'd love to get my hands on a Tri-Z 250 someday.

Transmissions are different 85 to 86

I think I'm gonna part them out if I was gonna build a 3 wheeler it'd be the 250 r.

[Yamawheeler]

Tri z would stomp on a 250r (depending on mods) if they are both stock. Tri-z those things were built to beat the 250r. Now if you say 350 r then Honda take the cake again.
