I'm following with great interest as I have never seen a 4 valve Guzzi opened up.Are the rocker arms bronze, copper plated, or?
Outstanding thread. You do nice work Chuck.Kurt
It's a lovely casting, isn't it?
ChuckTube between the front fork leggs seems missing on the second last pic....
I think you'll have better results leaving that brake lever at rest. The relief port is closed when the brake is applied keeping fluid- and air-from returning to the reservoir.
You are right, of course, but my theory is that the bubbles work themselves to the top in the pressurized line. When the lever is released, they go into the master cylinder. I've always done it and it works for me. <shrug>
Nice one. I used to do the cable tie trick on my 82 1100 Katana. Royal PIA to bleed with the brake fluid controlled fork anti-dive.Kurt
changed a bit more regularly
True, some do it. I'm not sure how well it works. I have mine on, and if tight, you can firm up suspension. Not that I think that is needed on the Lario. Stock suspension has that possibility both front and rear. I have stock at the rear too with this option, but may replace it some time.
Hi Chuck,I've had issues with sticking pistons before. Mine haven't been water affected but the seals have swolen, probably due to incorrect fluid being used by a PO. I've always managed to get them to work.DOT 3 is more slippery than DOT 4. It isn't as heat resistant and should be changed a bit more regularly but it works fine for a road bike. Doesn't affect any type of seal I'm aware of either. On a really reluctant Grimeca rear M/C on the Morini I fitted a smaller inner spring that did the trick for the piston return. It has a left hand foot brake so I can't meter out the pressure evenly anyway. Simply a coordination issue as I'm right handed. A bit more resistance helps me to not overdo the rear braking. Most of the time I'm better off forgeting it even exists. :DCheersRod
Great thread. About the rear master cylinder, the stuck piston problem you ran into once happened to me. The first time I bled the brakes on my LeMans IV, a few years after purchase ;D, I did it by the old open-the-bleeder-and-pump-the-pedal method. Not only did that not work, the first pump stroked the piston down to never-never-been-this-far-before land where it got stuck in the old marinera sauce.After a rebuild I learned to bleed as you did, from the caliper and also made a nifty cover for the front end of the master cylinder from some old rubber bit I had laying around. ;-T
