Steve, Tony,
I didn't mean to imply it was the bike's problem - I realize it's MY problem with my desire for low RPM.
I was out at a get-together of our local club, and spoke to one of the old-timer guys about this. He listened to the bike and gave a supporting opinion that the problem was carburation. He also said the same thing you two have about RPMs: drop a gear or two, keep the RPMs up and damn the neighbors! That's simply the design of the bike.
I think what's going on is that I'm unwittingly compensating for the carburation problem by keeping the revs low where the torque is low and before the engine goes through it's "warp shift" as different jets come into play. While doing that largely avoids the jittery problem, it is doing the bike no good.
Steve, I'll send the carbs down to you as soon as I can afford to, but as I want the cam kit as well, and based on our phone conversation, there's no point in my doing it twice.
On losing fluid in the Motion Pros I watched their video on using it, and read some comments on the web: a larger engine you suck some of the fluid right out of the tubes if the air gap at the bottom is too big and the level is set too high, and especially "don't blip the engine".
But the Morgans have steel rods in the tubes, no fluid, damps the pulses really nicely. What say you about them?
