I have a set of YZ 1977 straight wheels , incl backing plates and axles ,if you are interested. Not sure if they are the same as the TT , you would need to check .
Hi Walt the front and rear hubs would be the same lots of Yamaha models ran the same front and rear hubs

I thought it was only the 2 stroke Hondas that had those stupid tin covers but anything is possible with Honda. Can't understand why they would fit them onto 4 stroke as the Crankcase volume isn't important. I have a jig for the 2 stroke ones but I'm not sure if the XL500 would fit. What are the main shaft diameters. 

The gearbox bearing with a groove may just be the same as aftermarket bearing that comes with a circlip.
Dimensions of a 6205NR will give you an idea.https://www.bearing-king.co.uk/data/images/45278.jpg
If the bearing has just a shoulder on one side it can be machined into a normal bearing but ceramic tooling is required.


I will have to measure the crank shaft later today
Thanks for the tips on the bearing I will chase something up and see how I go .
I have seen the tin covers left off the XL500 cranks ? Not sure if this is wise or not ?

While I’m at it , I’ve ordered a Carrillo rod , pin , thrust washers and bearing From the states but it’s a two mth wait , these XL500 have the tin cover set up on the crank half’s do you do these sleepy ?
I want it balanced etc .
One of the oem gear box bearings has a groove machined in it for a steel ring to go around it to lock it
in the cases but this bearing is no longer available, I’ve heard someone buy the same size bearing and machine the groove into this one .

Thanks for all the info guys , it’s a XL500 bottom end and some of the oem bearings are no longer available. Sounds like C3 grade is my best way to go .

Vintage Track / Re: XT500, de rake? Better turning?
« on: March 15, 2019, 05:24:54 PM »
I de raked a TT500 frame years ago 27deg it turned better but it lost it original look and value.
The Flat track TT500 bikes in the USA are all de raked 25-26deg but this isn’t mx riding .
