finally got my model 8 running again, trouble is - a funny flat exhaust note and noticed that the exhaust started to glow when i open throttle.

i have done some searching on here and it seems that must be far to retarted.

is there anything else i should be looking for?, also, the manual says that overheating could be caused by a faulty auto adv/retard unit, but how do i check?

Was the bike being ridden, or sat stationary for a period of time with the engine running?

Sounds like the ignition timing is very retarded.

th bike was on the stand, it was only running for about 3-4 mins,

i assume that the exahust valve must be opening before all the fuel is burnt and some combsution must be happening in the exhaust pipe

Then why don't you check the valve and ignition timing and report back ??

PS Why leave it running 3-4 Minutes ?.

re-set timing - it was way out - around 15 degrees i reckon.

1st kick - purrs like a kitten - a very satisfying feeling after 12 months of on/off work.

I know its an old thread but will a finned ally diffuser on the front pipe against the head stop the pipe from going blue???

Thanks paul
