Yz125h 1981 restore

[Simintrev]

Hello everyone ive started restoring my old mans yz125 1981 motocross bike! Seems theres a few parts ill need and i hope some people have some knowledge about these old machines.
It seems they dont make the steering headset seals.
And i also need a new clutch basket and plates as the basket has some nice big groves in it.

Cheers everyone!

Checking the one review the guy asks for return address as they didn't fit but the company replied in a professional manner. Send them an email.

Awesome thanks for your help! I got my hopes up thinking i found some seals and then went to cart to realise there discontinued. Cheers for that ill do a measure up and double check! Now the dam clutch basket is next on the list.

Also do you guys prefer to powdercoat or paint your frames?

Personally after finding that there was an all balls kit I would just buy the all balls kit.
Shit it looks bloody good nick.

If it's going to be used in anger in VMX, paint so as it can be touched up after the inevitable dings.

[Simintrev]

Its the same case of does it come with the rights seals as it looks like the ones in photos are just dust seals not the single acting lip seals to keep the water from escaping out the headset. Ive emailed those sites anyway just to double check. Thanks for the quick replys everyone!

Harhar typically the cleanest part of the whole bike is around the headstock.
