I'm pretty sure I know the answer to this, but I'd appreciate any advice from the experts. 1973 850 with 8300 miles. Picked it up last year and had a Brit bike/auto guy work on it over the winter. I've got Tri-Spark and Amal Premiers on it and it's running really sweet. My issue is that it's missing shifts, particularly 2nd to 3rd. I probably get 50% of the shifts in, the others hit a false neutral. Another stab down and I'm in 4th. I find if I stab the shift a bit towards the middle of the bike instead of straight down I'll have a higher probability of hitting the shift. Gearbox was not touched over the winter. Is this my layshaft bearing telling me it needs to be replaced? Pics here: https://plus.google.com/photos/10016038 ... banner=pwa
