For anyone with rough shifting...
With just over 2500 miles on the bike, the only thing that I found troubling was intermittent rough shifting. It did not seem to follow a pattern that I could detect, but it seemed to be worst when going from 2nd to 3rd. I was thinking it was getting slightly better as the miles piled on, but I was still trying to figure out if it was really the bike needing to be shifted a certain way that I was not doing, or if it was me, or both.
Earlier today in the UK forum, Magnon, who I shall now consider to be a prince among men, and whose shifting was similar to mine in its poor "quality" posted that he had discovered that his clutch master cylinder was grossly overfilled. He removed some fluid to bring the level down to where it should be, and now his bike shifts nicely.
So... I had to go check mine. And here is what I found. No sooner did I get the bolts holding the master cylinder lid loose (T-20, BTW) but fluid started flowing out!
Put a towel down, as there is quite a lot extra!
I couldn't find my little squeeze-bulb thingie, so I just used a couple of paper towels to soak up fluid and pull it out of the master cylinder until the level was about half way up the inside.
After buttoning it back up and cleaning off the bike where a few drips managed to go, I took it for a little test ride. I only rode a few miles on small backroads, but there was no traffic, so I was starting and stopping and running up and down through the gears constantly, using different rpm shift points, varying rates of acceleration, varying speed of moving the shift lever, and stayed out long enough so the bike was up to running temp. My opinion is:
SHIFTING PROBLEM SOLVED!
The bike now shifts as I would expect it to.
