    Opened Valves -- Found a Squirrel Present

    I guarantee this is a new one... Finally got my valve spring compressor in the mail and went to town taking the valve springs and plungers off. Everything was going swimmingly, I have to say the valve spring compressor was a fantastic purchase. So I get to the exhaust valve on the right hand...

    Exhaust Louder on One Side

    First post. 1981 XS650. The bike has a long history of sitting for long periods of time. I got it running 15 years ago after sitting for 10. Then, due to a family feud too long to describe, the bike sat again for until two years ago. Changed the oil, rebuilt and cleaned the carb and some...

    For Sale - Delkevic Header

    Brand New Delkevic Header for sale. I have had two of these because I thought I was going to need to chop one up for the creation of a unique header system on my bike. Turns out I didn't need the second set. So now I have a Brand New set of headers intended for a '79. I believe it will fit...

    exhaust leak at flange...

    I've had a pesky exhaust leak with my xs... It leaks right at the flange. I cleaned the surface with sandpaper, and I've tried a couple new sets of gaskets. tried double stacking them, even rtv copper as a last resort, but nothing will seal it. Torqued to spec every time. Anyone else have this...

    Backfire through right side intake

    I have a 79 special that wasnt running to good when I purchased it so the first thing I did was tear off the carbs and give them a good cleaning. The bike ran much better once the carbs where clean but it sometimes will backfire through the right side carb at about 1/3 throttle. I didnt sync...

    Left cylinder running hotter than the other side

    Okay, so a bit of back ground on this before i start. I have rebuilt this TX650 motor, inside and out with .25 over pistons, new wiring with pamco and brand new VM34's mikuni carbs. Now, i've had it running a few times and i immediatly noticed that the left exhaust pipe is hotter than the...

    Plug chop, too lean I think?

    Hey All, '79 Special II, all stock engine. Earlier this year I de-restricted my exhaust a bit (punched 1/2" hole in the stock baffle) and have really enjoyed the improved "Oomph" in the motor...and the sound is perfect for me. However, the other day I was thinking that perhaps I...

    Will an XS1B exhaust "fit" a 78/19 engine. I'm not talking a perfect fit but the exhaust ports, length of the pipe drop ??? tim

    Baffles for 1.5 inch inside diameter pipes

    I have some custom straight through drag pipes on my XS with an inside diameter of 1.5 inch ( 44mm ). They need some baffles as they are raising the dead. All the slip in baffles are measured based on the O/D of the pipes, not the inside and I'm struggling to find any that will fit in my pipes...

    Early XS Head Pipe Differences VS 74/75 units?

    I (like a lot of others) am having trouble finding a set of OEM double-walled head pipes for my 1972 XS-2 restoration project. The only concrete differences I've found are from this PDF: http://www.biker.net/70-73_650_parts/engine/70-73_exhaust.PDF, which shows the following for the early head...

    XS 'Commando' bolt on performance?

    Hi there team, I have a stock 78 xs650 standard which I have just purchased. It runs beautifully but was looking for a different sound as well as the chrome flaking off the exhaust in some areas. If the Commando Style Megaphone Mufflers from XS performance were bolted onto the stock...

    Fuel in my exhaust

    I have a 1980 xs 650 that I hard tailed, installed a pma and Pamco. I have rebuilt bs34s with stock jetting. The jetting that was one step up fouled my plugs within minutes and caused soot and fuel out of the exhaust. I adjusted the cam chain, valves and timing. The floats are brass and at 27.3...

    Let's play: Quiet down CoconutPete's exhaust.

    The origin of my exhaust is unknown. By the looks of it - it could be a MAC 2 into 1 header. Who knows. It doesn't sound bad. Just a little loud for my taste. I don't want the bike to sound like a vacuum cleaner, but just not so loud. Does this thing look familiar to anyone? If it...

    Ill start from the beginning. I bought this bike as a stock 1980 xs 650 special and i was 19 years old. i originally went with the brat set up from visual impact because i planned on this being my daily rider and my old man thought a hard tail would be to much as a daily rider. I installed a pma...

    Complete Bobber Exhaust, $22.99

    I'm in the process of getting my '74 TX650 ready for a TC Bros hardtail. After removing the extra long stock mufflers I notice that the stock headers are in very good shape. I scrounged around town for some exhaust tip turn downs (turn outs), the only things available are flimsy 2" ID. My stock...
