1979 XS650, PMA, Pamco electronic ignition, no battery, kick only, mikuni round slides 34s.
I just got this ride put back together and I have a few issues that are keeping me from being comfortable riding this thing.
1. My advance shaft - When I tighten the nut on the advance shaft to what seems to be a good snug fit, the shaft will not advance. The centrifugal force will not open the springs when above 3200 RPM. When I loosen the nut to where it is barely on there the shaft will advance. I was going to just put a lock nut on there loosely and call it a day but something just doesn't seem right and I don't want to cause further issues. I feel as if I installed the ignition and the new advance assembly according to the directions so im just lost here.
2. I got the external oil cooler mod kit and it is leaking like crazy. Again, it was installed per the directions I received but I cannot get it to stop leaking. I've torqued it properly from what I can tell but not sure if I have something incorrect here.
3. I purchased the 34 Mikuni Round Slides and they came with a stock setup. 175 Main Jet, 15 Pilot, and a 6pF?? Needle I think. Anyways, I know I need to road test this bike and get the jetting and air screws dialed in but I was hoping to start with something close. I don't want to purchase a bunch of main and needle jets for testing if I can get it somewhat close. I live at 75' above sea level and it's hott (Tampa FL). I am running pod filters and cutoff exhaust. Cut just under and behind the stock foot pegs. The engine internals are bone stock. The bike runs ok now but I want to get it perfect so I am hoping that someone has a great starting point for me with these jets.
Anyways, once I get this stuff knocked out I feel as if I can actually get out and ride this thing further than just around the block. Which is about all I feel safe doing at this point. Thank you all so much in advance for your help and support. Please let me know if there are questions you have for me and I can reply quickly.
