OK,
For those who dont recall - 1981 XS, all new wiring and PAMCO + e-advancer.
Had carb issues which I have solved by having them completely rebuilt.
The copper cup for the e-advancer spun a bit and threw my timing a little (still rideable but popping on decel and then started to 'pop and miss under load)
Got a new copper cap... pulled out the advance rod, put on the new cap (the way I was advised by PamcoPete) and even used locktight on the little pin to make sure it doesnt move again! All looks perfect, threw on the left side and tightened it up.
Now, bike wouldnt start, strange. Started messing with the timing and if I put it on FULL retard it starts but idles low, grumpy and pretty bad all around. Tried turning the plate to FULL advance, it starts, idles, revs (pops when you let throttle off) however when I try to ride it, it pops, and stutters under load (if I wind the throttle on slowly its not too bad, soon as I try to 'go' it pops, backfires, stutters, etc)
Ill hook up a timing light on Sat and try and check the timing but I find it strange that I cant get it started unless its fully retard or fully advance (or almost full)
Fuel, carbs, etc are all untouched and it did over 200kms on a run last week (before the copper cap got damaged)
My questions really are:
Timing.
1. When trying to set the timing I have the left piston at TDC then put the advance rod in and everything lines up. Is that right? Having said that, I dont see how with the pamco you can set it wrong, the pins simply line up and thats that, the copper cap doesnt allow me to put it on wrong... am I missing something here??
ie/ You cant 'adjust' the shaft, copper cap, and rotor with pamco, the only thing you can do is rotate the timing plate.
2. Advance rod assembly. I have done it as per Petes instructions (put on washer, then cap, then washer then washer then spring washer... and tighten it up... then put it in then put on the rotor side... when I tighten the rotor side up, I have absolutely NO freeplay in the rotor, cap, advance rod or anything... it turns nicely with the motor, but there is no play in/out or left/right... is there meant to be any at all? All seems good to me but just checking.
Cheers,
Peter
