My first TRI-Z

[Nite302]

Hey guys this is my first post to 3ww. I am fairly new to 3 wheelers, I've owned an 84 200m for a while and I just recently picked up an 85 tri-z 250. I took it in on trade, only which I only had about 200 bucks into. Its in pretty decent shape I'd say for the year. I got it knowing it needs a crank rebuild, I've since torn it down and found the cylinder needs to be bored or replaced. I have it down the frame and plan on reconditioning everything I can. If you guys wouldn't mind giving me the run down on these things.. i know they have problems with the fuel pump and water pump. Any advice you can give me on rebuilding these things like what kits I should get and what to avoid. I've only been able to find rebuildable crankshaft kits online. Are these any good? Any help is greatly appreciated thanks!

Ive never had any trouble at all with the tri z fuel pumps and even had the original pump on mine that we race now with no issues . the waterpump impellars are know for coming unglued after years but the new oem are not expensive so whenever you rebuild just put a new 1 in. And i highly suggest using oem crank bearings and seals and just find a good reputable machine shop to rebuikd your crank and you should be ready to ride . welcome and enjoy the tri z they are great bikes

Thanks for the reply. I did plan on going oem with the bearings and seals however I forgot to say that the rod does still spin but it is very stiff and havent been able to locate an oem crank or ANY crank for that matter. I have rebuilt motors before and plan on doing this myself. Are the crank rebuild kits trustworthy?

The hot rod kits is good just make sure you get a good shop to install it
