I read the thread about front fork springs and oil and just had to relate
personal experience on the racetrack in the late 70's.. I had been running
a Yamaha RD250 in the WERA production class and had stuggled with choppy,
underdamped fork action. The front tire would actually hop over rough
asphalt.. a little unnearving in corners. After doing all the normal stuff
(rebuild, new seals, new steering head bearings), out of desparation, I put
90W Hypoid Gear oil in the front.. and the bike never handled better. I used
90W for rest of the season.. Of course, I blew the seals out in the last race
;-). A footnote.. nothing does more to improve the steering "feel" of a
bike than replacing the steering head bearings, and periodically checking
them for proper torque.

 Subject: Re: Replacing front fork springs


The front springs on my '72 Eldo might not have been all sacked out but
I was bottoming out way too often for my taste, especially when two-up.
I had already 'rebuilt' the forks with no improvement. I bought the
Dutch WP progressive front springs from Moto Int. and experienced an
immediate improvement in handling, and less bottoming out. But it still
wasn't where I wanted it. Then someone on the Guzzi list said to use 70
wt motor oil in the forks (50 wt where it is colder). This brought
around further improvements. I wonder now if I had gone for the 70 wt
oil in the beginning, would I have bought the progressive springs?
