How to silence your Jota pipes?

Jotas really aren't that noisy compared to Deliveroo riders 125's and pretend racers with brain shredding exhausts. Some of the cars here, mostly Mercedes owned by Arabs, seem to have an explosive device to start them instead of a starter motor. Then they will sit there for ages with the engine running pissing about with their phones.

Haha. Reminds me of the SS Mangana, an old vehicular ferry that used to service Bruny Island, south of Hobart. I used to catch it on occasions way back when I was a youth.

It had a 2 stroke diesel engine that was started with a 12 gauge shotgun cartridge. It had no gearbox so the propeller shaft was driven directly off the motor. The only way to reverse it was to stop the engine and re-start it in the opposite direction. The start was accompanied by a loud bang and a puff of black smoke from the funnel.

The guys in the crew weren't too familiar with the procedure at first, and it was only a day or two after the boat started on the service that they failed to get the timing of the re-start right when coming into the wharf. They eventually got the engine started in reverse and revved the crap out of it in an attempt to stop in time, but it was too late. The boat was still doing a few knots when it crashed into the vehicle ramp. I don't recall whether any significant damage was done. I was only about 10 years old at the time.

The noisiest of all are Asians on pedal cycles riding two abreast on small roads.

I don't know (and don't care to be honest). I either sit on them or they stay in the garage. When I sit on them, it is more important to me how they handle. The rest is just collecting dust behind closed doors.

That said, there is nothing wrong with a bike looking good, too. It is just not the most imporant thing for me.

Maybe..... just don’t expect me to slip one into Lizzie. But then again, Phil The Greek may have trained her well.

A Greek girl I worked with once said her father always said “ Women are for breeding, men are for pleasure” take that as you may.....
 
This winter I have to quieten my Jota silencers, stainless copies of unknown brand. Will experiment with tube inserts picking up on the advice found here, but also interested in buying new silencers, hopefully TüV approved (part numbered?). Any recommendations? My local TüV turned a blind eye to the current pipes giving me an approval in 15 minutes, but it’s clear from reactions when on the road that sooner or later I will be stopped and then as Piet says the police will simply refer to the 84/89 dB stated in papers and probably lack of a DGM number on silencers. The more I ride the more pressure they will get from the public, you can feel the annoyance as you ride even with a muted throttle. Still using under 5000 rpm as I bed in the motor. Guess the alternative would be a new 600cc approx Aprilia or something electric!!!! Still riding, but not the same.

Hi, the stainless ones do have a different tone than the chromed steel ones. The stainless cans sound a bit more harsch, the chromed ones more "rounded" if you will.

still, both are very noisy... but I rarely get bad reactions on the bikes sound

Field Marshall tractors had the same starting system. Always enjoyed it. Ours was tracked rather than wheels.
