I've been having constant issues with my '79 Special II since taking it out hard onto the road for the first time since restoration. A few weeks ago, it started overheating regularly, along with a growing oil leak coming from the vicinity of the crankcase. I changed the oil, cleaned the oil filter and carbs, checked the points, valves and timing--everything seems to be in order. But it's now having a bit of trouble holding idle RPM and surges/bucks when out on the road. The left side valves/piston is fairly loud as well. Floats are set to 27mm for BS38s, which worked well before the bike started experiencing problems, so I don't think it's that.
So now I'm wondering if its an oil/fuel starvation issue and what the signs are of a faulty oil pump. Unfortunately I over-torqued and broke off one of the screws when changing the crankcase gasket the other day, so I can't check the oil pump directly until I get a new set of screws and get the broken screw out of the thread (if anyone has an extra one of the long screws or is selling/knows where to find a set of screws or crankcase, please let me know!).
Does all this ring any bells for anyone? Thanks!
