Spoke to a mechanic today from a store that sells 'Retro' motorcycles like mine at super inflated prices.
He said if it was the condenser it would be damaging/dirtying the points or something like that and that my symptoms don't sound like that. He said it wouldn't idle fine when the problem starts to appear. However, my bike still idles pretty smoothly even when this problem is happening, it only stutters under load/acceleration.
Can someone give me the run down on exactly why this might be a condenser? I've been enjoying playing around but lately it's started to give me the shits.
