exhaust

A while back I bought a couple ten packs of aftermarket exhaust gaskets. These are the ones that appear to be a coil of thin green foam wrapped in metal foil. They are not working well and easily crush down until the pipe collar flange is touching the head. My local Yamaha dealer does not...

Took the wife on a date Friday night, it was a glorious 10 minutes before the bike started back firing when I would decelerate and then after another 5-10 min, I would have to keep on the accelerator a lot to keep it running at the light. Stopped had dinner, got her running, but 5 min into...

Know how when you see a bike you want, you tend to look at it through rose-colored glasses? And after you own it for a short while you realize every Phillips head screw has been rounded off, among other problems? Well... that's me... hopefully not you! Anyway... I'm going through...

I have a '78 with mikuni vm34's, mac 2 into 1, 700cc, shell #1 cam. Carbs have 6f9 needle clip set in the middle (counting up from bottom it's #3) 159p6 needle jet, 25 pilot jet, 180 main, 3.3 needle valve. Has PMA and Pamco. It ran when I bought it, albeit a bit roughly. About mid range...

Roughed this out, pipes squared up with sharp 90 and 45 bends. 1 3/4 diameter looked a little more stout than the stock 1 1/2. The used Harley pipes only cost $25 pair. Will have to put some miles on them if all OK thinking of having some made up in stainless.

Tried to contact Gordon on his web site, says he's out of town til June ?? Now I see some of his posts here. I sent him a PM is that the best way to reach him and is he still doing exhausts? Gordon Where are you ?

I got a set of these machined up this week for the exhaust system I'm building. They are designed to work with the standard, finned clamps (hence being shorter than the tc/bros, pandemonium supplied dealio). You should be able to take this drawing to any machine shop and have them turn the...

I'm looking for some Triumph style pipes. I saw a nice set but don't remember where it was LOL. Done dealing with the tire kickers, Lowballers and wannabes so what's one more bike in the garage.

Looking for high exhaust, left side, something along the lines the Omar's was supplying.

I blew out my exhaust end yesterday on my 73 TX 650. Its the left side and just the end part of the cone. I'm looking to find a replacement part or possible advise on what is compatible as a alternate if I cant find a stock replacement. Any advice on where to find a part or what would work in...

After putting pod air filters on my '83 XS650 I am wondering what to do with the engine breather hose that used to run from a port on the engine back to the air filters. Do I just remove it, or is there anything else that needs to be done? Thanks

Just bought my first Yamaha 650 XS 1977 all appears to be original 17000 miles American spec , bike runs ok apart from a few flat spots during acceleration , have made no adjustments to the carbs to date. Have noticed both the exhausts have drain holes , exhaust gasses are passing through...

Hey guys, So I'm running an '81 with stock headers, but with no pipes and no baffles. Just engine and headers (surprisingly, it's not THAT loud). Am I losing power or performance? Some people say that motorcycles need "back pressure" created from the exhaust pipes or the baffles. Any truth...

G'day, Looking to grab a pair of Gordon Scott 2-1 Exhausts. Was looking through the xs650exhaust website but couldn't find a email address to contact him. Any idea if he's still in business? can someone pass me on a contact? Thanks Mike

So I see the OEM#447-14715-02 muffler clamp for a 1975 XS is no longer available. I see MikesXS has different sizes but nothing by that part number. What size was the clamp? Thanks!

I'm fabricating a pair of head pipes and don't have an old set for reference. Does anyone know what the correct length is for the collar on the head pipe? I'm guessing about 1", but I'd like to be exact. Thanks

building a 2 into 1 set up with 1.5 main tubes my question is what what size collector pipe 1.5 1.75 2.00 ??? I had a street 2 into 1 that has a 1.5 out let it just looks too small. would it breath better with a 1.75 or 2.00 or is there a reason it's 1.5 ?? ps' I forgot it's a 680cc 277...

Just wanted to share, harley supertrapps with no baffles sweet sound but to loud for me. Best regards from Denmark.

I'm just tri'n to figer out what exhaust to build what's the best for the every day run of the mill hardtail 680cc 277 rephase 2- 1.5" no baffle 2-1.75 some baffle 1.75 2 into 1 or 1.5 2 into 1 noise is not a problem, not sure on carbs yet I have a vm36 2 into 1 set up and a good set of...

I have finally re-commissioned the xs2 and had the engine running. Like a lot restorations of old bikes the real faults that stopped it all those years ago surface. The engine starts well off the kick start and does run evenly on the choke for a short while. I should point out that the engine...
