    Curved Drag pipes

    Folks-I'm interested in getting a pair of curved drag pipes like Gordon Scott used to make. My bike has been lowered, so there is no way pipes are going under the bike. I've got custom made mid controls, so running pipes next to the frame rails won't fly. Anybody know a shop that might make...

    Mid Controls and Exhaust

    Hey Gang, I want to mount some OSS mid controls on my '79 Special. The problem I run into is the stock exhaust on the right side interferes with the modified brake lever. I need to replace the exhaust anyway since it the cans are rusting out. The question I have is, if I get the headers by...

    Looking for some exhaust input/opinions

    Hi everyone! I do a fair bit of lurking here and pipe in occasionally. Right now I am trying to figure out an exhaust design to spend a bit of the tax check on. Its based off of the Gordon Scott curved drag pipes but it seems he isn't in business anymore. Another option i hadn't finished is...

    Home made baffles for shorty mufflers.

    Hello Just thought I should share my simple modification to make my short mufflers sound better and be quieter. The bike is a 1972 XS with the stock 650 engine. On the stock head pipes I have two Tapered tip 16 inches long free flowing mufflers. The sound with these mufflers was too loud for...

    Swing Headers Under Engine?

    Has anyone ever successfully swung his stock headers under the engine? I'd like to get that "TT" or "half-mile" look on the cheap. I tried swinging my '73 TX650 headers under the engine, and it comes SO close to working. Any ideas? Tips? It looks like it would work if I could bend the...

    shortie mufflers

    If I change out the OEM Mufflers on my 83 Maxim to shorties or slashes, do I also have to do anything with the carbs to keep her running strong?

    Rights-side exhaust popping & pulling vacuum. Help!

    Hey guys, it's getting colder here in MN at the end of the riding season and i've noticed my bike has been popping on the right side a bit. I cleaned the carbs and messed with the air mix and that helped for a while. It's started again and i'll make a list of symptoms and changes i've made...

    Will rusted out exhaust cross tube/joint cause backfire & stall?

    I've been breaking in my rebuilt motor and the bike has been running beautifully (amazing!) for about 100 miles. When I put the motor back together I used the original exhaust, which is in poor condition; a Knickle sized hole in the left bottom rear muffler past the cross tube, and the cross...

    Copper Exhaust Crush Gasket source?

    Can anyone help find a source for the copper style crush gaskets that would fit the 50mm exhaust port on the xs650? I'm installing an aftermarket header and need to put gaskets in. The wound fiber gaskets that are stock, just don't work the same. And finding the copper ones is proving very...

    Looking for new exhaust suggestions

    Hey all, Sorry for the rather newb sounding thread, but I've looked through the forum and haven't been able to find what I'm looking for. I have a mint '81 650 Special II that I've only owned for a few months, but I love it. The only bone I have to pick is that I could use some more oomph...

    fresh from a 20 year sleep 78 Special

    I bought this from a fellow who had it in his garage for ages. Just put it up on the lift to see if it will start and am impressed at how stock it is - even has the tin straps holding the harness to the top frame member. Using my ever handy CTC Powerbox, was able to momentarily jump the...

    Muffler fell off and bike bogged down :-|

    I'm new to this site, this is my first post. I just got a '77 xs650 and could use some advice. I was cruising at 65mph and my muffler falls off my headers. (I have the Mac 2 in 1 exhaust) Before I could find a place to make a U-turn the bike started bogging on one cylinder. The second...

    head pipe - muffler separation, cause and effect?

    So I was just heading home for lunch, doing about 110 (65 mph) on the highway, bike starts running like crap, coughs a couple of times and dies. mmm.... I'm just about to call in the cavalry (read that as wife), I look down to see the left side muffer separated from the pipe (see pic). Wait a...
