Rear cylinder is still not playing the game. With idle set 2000 rpm It idles 5 seconds then the rear cuts out And runs on the front for 10 seconds at about 1000 rpm and keeps doing this. "Seems" to run ok 2500 and over.
The coil checked ok I put a wire across from the + front coil to the rear to ensure both has the same voltage supply.
new HT wires, plugs, and end caps, also swapped coil from a later model bike just to test(same)
The intermittent nature of the fault makes testing a bit inconclusive.
I put a inductive timing light on the rear and it continues to flash when not running on the rear but as the revs increase back again the light stops twice while revs go up (how weird is that)
I reduces the plug gap to it spark easier to see if that helped it didn't.
I pinched the vacuum pipe going to the fuel pump and the petcock with no change
Any thoughts
I am stuck at the moment
Thanks
