Back in late January I picked up an R75/5. I really like the bike. It runs well once it's started and it's way smoother than my BSA, especially at higher speeds! However, I've always had a problem starting it even with the enrichener and the problem gets much worse in lower temperatures. With that in mind, I rebuilt and rebalanced the carbs. I replaced all the jets, making sure all circuits were open. I balanced them with a TwinMax, tuning the idle mixture in the middle of the mixture screw's very narrow in/out range. I also checked the valve adjustment. The left intake and right exhaust were slightly off, but only by very little-about a thousandth. I also replaced the battery. Next I went to adjust the points. Lo and behold, the PO replaced those with a Dyna III. The timing was off-too advanced at idle, too retarded at 3k. So I replaced the advance springs, which fixed the problem. Timing is almost spot on, with a little ghosting. The idle was still off so I added the springs to the slides as Snowbum suggests. No difference, so I took them out. A few weekends ago I replaced the timing chain, tensioner, tensioner spring, and crankshaft and camshaft sprockets and re-timed the bike. No change. I figure the ghosting I should be able to adjust out by moving one of the pickups on the Dyna III. Argh! I think the starter also needs to be rebuilt, but, taking the starter out of the equation, it's still a bear to start with the kickstart. I'm not sure if this is normal, but it seems like it wants to fire on one cylinder while starting it. Kinda like a whir-whir-whir-boom-whir-whir-whir-boom. So, I'm now begging you guys to give me some more ideas on what else to check.
