    Hello Ron Bell here. you'll see me as Stump Puller in the forum. first post so here we go.

    I have a 390 that is being reserrected. tore it all down, sandblasted the frame, new paint, new Piston and bottom end. now the slow task of going back together. started with the Forks tonight. had to build a tool to hold the dampening Spindel in the fork tube. 3/4 inch pipe and the grinder is all it took. worked better than I expected. used case seal on the stepped washer at the bottom and low strength thread lock on the bolt. (found the PDF's available very helpful)

    Any recommendations for oil weight for trail riding? I bought 10wt, but read 20-50 engine oil in the manual. thought that kind of strange.:confused:

    my Fork tool is a little Barnyard, but being 3 feet long I could stand the fork on end when sealing the bottom bolts. will post more pictures as the project moves along. wish I had taken a few before I started. It was a sad case. rescued by my brother from the Junk Yard in Idaho.

    Hi Ron,

    Welcome to the Vintage forum.:thumbsup::cheers::applause: I have heard to use either 10 or up to 15 wt 6" from the top but I'll let others with more experience answer in here.

    Post up some more pics of your barnyard tool , how you made it in detail.... a lot of people will benefit. Most people will tell you to hit it with an air impact and then you don't have to worry about it spinning.

    You have a great bike to work with!

    Classic.... everyone has/uses the same means of supporting the swingarm.... soft baling wire !!

    It looks very good. What kind of Bars? Bar Clamps?

    Keep the Kitty Happy. You never ever want a pissed off Kitty......

    Depends upon your weight, riding ability and so on. If your over 200lb, I'd go 15wt-20wt at six inches from the top. Springs out, tubes collapsed. You can always add a little more oil, if you still bottom too easily.
