I just installed progressive springs in my Venture (to replace the air ride) and I have an extra liter of BelRay 15w fork oil.
So... I go to thinking, although I have no problems, I'm sure Fiona could use a fork oil change.

Maybe someone can answer so questions

1 Can I use this 15w oil in the 81 750K?
2 My Yamaha holds 409cc in each fork BUT the procedures called for filling the forks 5 1/2" from the top  of the fork tube while they are compressed. Is there a similar procedure for the DOHC?
3. Would the 17psi in the front forks be maintained at that level?

I was thinking of replacing the oem fork springs with progressives on Fiona as well but she still rides nicely

Any help would be appreciated.
