Out of curiosity: how did the Webcam timing finally turn out? I ended up doing the last one as a 50-50 split, so it came out like an old Dodge V8 engine ("A" blocks) cam, with equal opening vs. closing for the intake valve degrees. When that was done I checked the exhaust(s) and they were also 50-50 degree splits, so I left it that way. The owner noticed it immediately when he rode off.
He installed it into the stock cam sprocket bolt holes about 2 years ago when he rebuilt the engine (836cc low-compression version) and it became a high-RPM engine. This bothered him because he has stock springs, so he wanted the power brought down somewhat in the band. I measured the stock setup as being 5 BTDC intake opening and [a whole bunch, like 50 ATC closing], so when I slotted the sprocket I moved it to 22 BTC and about that many ATC. I had to skip a tooth or two to get it there, as my slot was limited by the lightening holes in the sprocket.
After all this, it started almost as soon as I touched the start button, a major change. He said it pulls much better in the 4000-7000 RPM range now, too. He's afraid to go over 8000, probably good considering the tall lift (it's a 41a cam) and stock springs. He has had several nuts come loose on the adjusters, though. The whole bike is coming to me in April for a "fix these things" tour, including the oil leak that cropped up on the front of the head gasket.
