Running smoothly.
Decided to install a Red Centre ignition system.
Current bean can is on the limit of adjustment to get S mark aligned at idle - approx. 950 rpm.
Fitted the Red Centre, can get it to run OK but at the limit of adjustment and can only get the Z mark showing in the window and at 1150 rpm.
I am wondering if the cam chain is off by 1 tooth. Would it even run if so. Records show the chain was replaced approx. 10,000kms ago but not by who.
There is record of a persistent 'surging under load at high revs' issue in the last 10,000 kms (after the chain replacement) which may be unrelated. Records show the bean can was replaced to solve this issue but no mention of whether replacement was a new or s/h unit. Notes say surging problem returned.
I can chuck the old bean can back on and ride around happily for now but I reckon something is amiss.
Hoping to get some input before I start disassembly to have a squiz at the cam chain in case I am totally off track.
