Hello,
I am restoring a 1979 SF 1100. It's been sitting a while and I thought it might be time to run some gas through it and turn over the motor, splash some oil around the crank... She was in a front end collision earlier this year and I am slowly getting her back on the road.
I had to squirt a little starting fluid into the carbs to get her to turn over, but the battery is holding charge - which is an extra good sign as there are some mysterious electrical wirings and there were a lot of loose ends after removing the fairing - and the starter/ignition seem to work fine.
With the choke and throttle closed, however, the engine races like it is in full advance WOT. I didn't notice it at the time, but two of the boots between the airbox and the carbs (the outer ones) have slipped off and are otherwise not sealing the inlet side of the carb. Maybe this is causing a lean mixture? I'm gonna truss them up and we'll see what happens...
Anyone ever have an engine race out of control after storing for a while? Should I dissasemble the vacuum advance to make sure the timing linkage isn't stuck? Seems unlikely... I've gone over the contact breakers in the older, smaller XS bikes a bunch, but haven't ever tackled the XS11's. Before I start tinkering away (don't worry, I have a gorgeous LG I can still ride just wondering if I am looking in the right direction?
Thanks!
