Had the Project out yesterday for a run on Bosch plugs (colder plugs as I thought to eliminate pre ignition from the list of causes) it did run well and I stopped three times to try hot starting, started every time, I am beginning to get a bit windy about the volume of the Goldie silencers though, glorious it is but loud.
Now I reckon it would be toned down a bit if siamesed (wishful thinking?) and I wonder if it would twitter if Siamesed more or better than with twin pipes

Bill, you know the old saying. "If it's too loud your too old". At least if the tintops can't see you they will hear you.
Cheers

I have a plain sausage shaped silencer on my  old Matchy out of stainless steel that twitters on the over run, go figure. I keep back off just to listen to it.

cheers Terry

Mines a mockery of a sham. It's mostly 1949 with '39 girders which are a straight swap!
