I don't have a problem but I can see my other half getting the hump and my neighbour is a decent bloke so I don't want to upset him if possible.

It may have sounded louder as I had it running just outside my open garage door which may have been reflecting the sound back towards my house. My daughter said she could hear it in her room when I got it running.

If you want a quite engine to run at home get a Wolseley WD2 .

Oooo... You've got the posh cast exhaust - it's often just pressed steel, and they are even worse.

Stick with what you have, and take it out in public for paying punters to "enjoy".

I think it may sound quieter in a field rather than my enclosed garden. How do I go about finding out when and where the shows are? Is there a go to place or person to contact that you could recommend?
Thanks

The answer is obvious - don't run it at home; get yourself booked into some local shows! You'll soon get into the swing, meet some folk, have fun - and do it some more...

Thanks Martin. It is a substantial piece of metal. I'll just have to get used to it. Thanks for the info. I'm guessing posh means good from your comments

I have this mushroom silencer which was on my Bradford until I made something closer to the original. As you can see, it has fancy spiral fins on the inside. Not sure how much they contribute to its silencing properties though - the American term 'muffler' is probably more appropriate.

Nick,

I would suggest that the fins are not for noise reduction but to accelerate the exhaust to cause a pressure drop to help suck the fumes out.

Wow, an extractor exhaust - must be worth another half a horsepower.

Isn't that a Bentall Pioneer exhaust, Nick? Would you like to sell it it to me? Please!?

Those cast Amanco silencers are supposedly copies of the original early ones. They are bloody awful things to look at and sound worse! You can buy an authentic pressed steel one as advertised in SEM. Much nicer looking.

As for the noise, if you want to mute it a little for home running, unscrew the exhaust tappet screw a couple of turns. It'll labour a little bit, but takes the 'crack' out of the sound.

Though it wouldn't stay in too well....for running at home you could stick a few stainless pan scourers in the exhaust to muffle it at home....
