Exhausted

Exhausted
I have a Harris exhaust with a race baffle. A straight perforated tube with no baffling material around it. If I wrap some glass cladding (?) around it, will this quieten things down a bit? Would I need to retune the carbs?
Re: Exhausted
Yes a bit and possibly?

Re: Exhausted
I have swapped from Harris race baffles and to the street versions on the same jetting without much if any detrimental affects (on a standard engine with std jetting though).
My advice would be do it and run it, at worse it will run a little rich, which wont cause any damage.

Re: Exhausted
Ok, Ill do dat den. Thanks.
Re: Exhausted
I’d assumed that the race baffles are supposed to be be packed with fibreglass, like a dirt bike baffle. They sound much nicer with packing, booming without being too raucous.
Having run with road and race baffles with and without packing I prefer race baffle plus fibreglass packing myself.

That is odd, or am I misreading this ?

No the race baffle is straight through but the tube is perforated you can wrap that, restricts it a bit from no packing and will quieten it a bit. The road baffle is a completely different bit of engineering which restricts the exhaust somewhat more and quietens it quite considerably.
Re: Exhausted
This is what needs baffling. I ordered some material today. Hopefully here by the weekend. Ha ha ha ha! I kill me sometimes.
Re: Exhausted
Back when we all had a Arris, we had one street baffle we'd pass around for MOT time, I still have the said Item, I got it chromed years ago when I was on maintainence at a electroplaters. Saturday afternoon Asian lads, plenty chrome on Jesiboy, they did the Supertrapp for my XT500 at the same time, I had to emery the joints to get it to go back together ho ho, so plenty on very shiney! its somewhere in my workshop I got a stainless race baffle made not so long ago £85 at Zorstec in Shipley

Re: Exhausted
So, I wrapped the baffle today. I would say it has taken the edge off the sound. Nothing more. A bit less harsh,maybe warmer ( as someone said). Cant say more than that. Ill run it like this for a while and see if I get used to it. (Couldnt get used to the un-wrapped baffle.).
Ill let you know.

Re: Exhausted
I bought a second-hand Harris pipe from this forum and have only recently fitted it to my bike. The first couple of ride-outs went well enough but today the bike kept cutting out. It would start again almost immediately and tick over but shortly after I pulled off it would stop / cut out again. Eventually, once I got it warmed up, it was ok but when I went back out later - same thing with a few, loud, back-fires too. Bike was fine on the old exhaust... Jetting problems maybe?

Re: Exhausted
Sounds like your main jets are blocked and picking up dirt in the carb remove brass screws and flush out carbs
Re: Exhausted
Nope, it was the little blue connector that comes from the Dyna S ignition and connects to the coil wire. It had a bad connection that was breaking down when under load. Got lucky finding it as it's something that could've got overlooked while you replace a few other, expensive parts trying to remedy the problem.
