parts that inter change with TRI-Z 250

[MTS]

Howdy....

The YZ 490 swap was mentioned a couple of times in this thread.....
What year 490?
Air cooled, or water cooled? Was there ever a water-cooled YZ 490? Sorry, but while I have spent a ton of time on lots of different bikes, my 490-nese is sorely lacking...
What about the rear-kicker design of the 490?

A 490 swap is not in the cards right now, but it would be something pretty darn interesting to do later on, as I have access to a couple of different YZ/IT 490's...

PS: Does the Banshee rear brake rotor work on the Tri-Z? There are some interesting wave rotors for the Banshee out there....

Go for the IT 465/YZ 465 the the yz is a 4 spd the IT is a 5 spd they where late 70's earlier 80's produced, the 490 has a awful head design that keeps it detonaating no matter what...(personal experiance along with other peoples views) the 465 is a much better motor as it dont ping and makes bout the same amount of power as the 490

My .02 cents

I think the banshee brake rotor will work if you use all the parts from the banshee like the carrier and stuff. It will not work if everthing on your Z is stock.

Actually they don't unless you have wear on at least one of the parts. Fresh you could barley them on.

. i have 2 banshees,had 1 warrior and still have a 250x, i have 2 sets of honda 250x,300ex and 400ex hubs.i have put those hubs on all my yamaha axles, which banshee and tri-z have identical axles.so i guess it all depends on your tri-z vs. another.but i KNOW FOR A FACT, that i have done it.my stuff fits tight on all my bikes, no matter which way i mount them. i have had no problems. my advice,get 250 x or 300ex hubs, they will probably be a little worn and easy to install.

Do YZ250 crank bearings and seals interchange?

[Tri-Z Pilot]

I'm pretty sure that the bearings and seals from 87-94 yz 250's are the same, I may not be exact on those years but it's something like that. I used a right crankcase seal for a 92 yz250 on my z, so that is definite, just havent cross referenced the parts in a while.

[Yamahauler]

I cross referanced the parts from the 85 yz to the tri-z, they are the exact same.

thanks

[Tri-Z Pilot]

Yeah, it's like 85-94 maybe even 97, yamaha likes to use a lot of the same stuff.

[Yamahauler]

You can buy Moose crank bearings on DK for the YZ and they say fits machines 1979 - 1987. Maybe they changed them after that.

Also, it says the 85 YZ clutch fits on there. Is there any aftermarket billet clutch you can get for the YZ that will fit the Tri-Z?
