i disagree that straight-through mufflers on big thumpers are anti-social.

If anything, i believe they are an essential safety feature.

Commuting on my thumper, if anything, i don't scare motorists because they can hear me coming, i don't silently appear out of nowhere.

I have had almost no issues with motorists cutting me off when driving behind them in a low visibility area.

(The high visibility jacket and high-beams might help too )

I think there's something about the noise of a big thumper with a straight through pipe that sub-conciously demands much more respect and space on the road, than say, a silent two-stroke scooter.

Anyway, at least we don't use Harley straight through "drag" pipes that are 20 times louder than a thumper and definitely mucho more anti-social.

I did a Christmas toy-run ride-out last year, and spent a lot of time riding next to a Harley on drag pipes. Much as I like a nice fruity pipe, this was awful. It was a hard-edged hammering sound that quickly got unbearable. If you've ever fired up a bike with no exhaust headers on (just to test it, like) you will know the sound. The trick with an exhaust is to get it loud and yet mellow. Reverse-cone meggas used to do this on Brit singles and twins. Haven't seen any for sale for years, though.

Glad I spotted this thread!
I was on my way to the gaeage to fiddle with my '03 XT. A previous owner removed the baffles from the stock 'pipe and I fitted a K&N filter. Was followed all around Spain and Morroco by an irritating burble and pop on closing the throttle. Just been saved hours of messing.

My mechanic has suggested turning in slightly more, maybe half a turn to richen up a bit for the straight-through pipe.

Turning the mixtures screw IN makes the mixture RICHER? Not the other way around?:confused1:

I thought the carburetors sucked gas out of the “mixture” hole so more open equaled richer..( opposed to the air-screws in simpler carbs, like 2-strokes)..

Its a CO/fuelscrew, therefor:

Screw out = more gas (richer)
Screw in = more air (leaner)

If it was an air screw, like on a typical two stroke, for instance your're moped, its the other way around, cause then its a airscrew.

Fuelscrews are often in the front side of the carn, airscrews on the back (typicalle behind the idle/rpm screw)

When I bought the Arrow pipe for my 99 XT600E I was told there was no re-jetting required, I bought the bike used and recently when I had the carbs apart for cleaning I noticed the Pilot screw was set at 1-3/4 turns out from seated.
