I just picked up a 1982 Yamaha yz250 and am in the process of changing the steering bearings. I notice the lower steering seal is pretty rough. I believe the part number is 93107-30009-00 and is no longer available. Anyone aware of other options that will fit or sources to check for that exact part? Thanks!

Those seals are an oddball , leaving most bearing houses scratching their heads. Have heard of using two generic type seals of appropriate sizes, stacked, but not sure if it would hold under pressure from the system when hot.
Also, the steering stem must be near perfect for any hope of any seal being able to do it's job.
But I did find the size on another site...

I couldn’t find this particular brand but used the dimensions and located them on another site for $3.00 from http://www.avxseals.com. They seem to be the same so we’ll see.
Thanks again for all the input!

Ended up buying one radiator and a hose and they really mangled up the radiator to twist the fitting so they could run a long hose up to the top.
I am debating making a kit with both the radiator and different hoses that eliminates going through to top triple clamp.
