exhaust

I have a 77' with unknown miles that I recently acquired. Changed all fluids, set lash and cam tensioner. Built a set of baffles for the chopped stock pipes, and once it quieted down I noticed a couple of annoying noises. The first is a pfft sound (put your lips together and blow out air) at...

i have a 1981XS650 SII. i can start the bike up and ride or let it idle. but after about 5-10 mins then engine races, rpms go higher and i don't know why? Then when i shut it off i cant get it started again?? it just wont fire up.. I don't know why? Could the 2nd start be that the battery is...

Hi my name is Scott, I live in Boonville near Columbia Missouri and I recently bought my first xs650. :D I would insert a pic but I am new and could not figure out how to do it quickly. It passed inspection and runs great. I bought it to make an old school bobber but that will have to wait...

not sure if everyone has seen these for your restoration needs http://www.xs650.fr/index.php?page=echappement-xs-650 Price seems to be 380 Euros (get you converters out)

I purchased the Mikes Reverse Megaphones and the inside diameter of that pipe is 1.73228 and the outside diameter of my original headers are 1.5748. I need to fill that gap and then clamp them together. Mike's sent out one of those multi--shim things but even when I put that on my header pipe...

I thought maybe a few of you might be interested in this little exhaust mod. Thrush 1.75 in and out glasspacks, stock headpipes, and a bit of welding. The only modification to the bike itself was cutting off the studs that the passenger pegs bolt to, then drilling those brackets out to allow a...

Hey simple question about exhaust wrap. i have a 81 Xs650 SII. engine, exhaust and carbs are stock. i like the look of the wrap on the exhaust, im going for a "cafe" kinda look. if i wrap the exhaust will that affect anything? will i need to Re jet or anything like that? mess with the air fuel...

Hi, I've been working on an newly acquired 1981 SH for the past week and this forum has been an incredibly helpful resource. I'm getting backfires out my left exhaust. She'll start up just fine but when I open the throttle it starts backfiring, going back to idle it'll backfire some more...

I Know this may not belong in the garage, but I wanted to mention how fantastic Dan, and Pandemonium Cycles is. I had some issues getting my Ya-Mama exhaust after ordering as a result of people being out of the office, and after getting in contact with Dan he went above and beyond to accommodate...

Hey everybody, first technical (read: begging the advice of guru's) post here so bear with me. I got my wheels off to paint and yanked the exhausts as well, as I bought some heat wrap to do the headers. Now that the stockers are off, im hating the look of them & the connecting tube is kinda...

I want to wrap my exhaust, but I'm not sure how much wrap to buy? Any pointers on working it out?

As the title states, I put new exhaust gaskets in and bolted up the pipes. Now the flanges are not seated flush to the head. I know these are crush gaskets and will have a bit of give but there seems to be a decent enough sized gap to cause me a little concern. I'll try to post some pics...

Anyone order one of the gordon scott 2 into one under bike exhaust systems? I think it looks pretty sweet just wanted some opinions on fitment and sound. Sent an email to him yesterday and waiting for a reply on price.

Sorry for the noob question but this is really bothering me... I was hoping someone could help me out with the exhaust on my '76 XS650C. It has stainless headpipes on it with the normal finned exhaust flanges, but there is nothing actually holding the head pipe to the exhaust port on the...

I talked with MMM for a bit yesterday while ordering new chain, sprockets, and some other bits and pieces. I always enjoy ordering from 650 Central because I end up learning so much during the process. I am currently running stock 17/34 with just the headpipes. I mentioned to MMM that I...

I have just fitted a Hugh's PMA and wired it (via the regulator/rectifier he supplies with it) to the battery - a fine, bright spark from both plugs when I turned the engine over with the kickstart (plugs out, and laid on the engine top to check the spark). THEN I disconnected the battery...

Hi guys, and girls, im a new to this forum and forums in general. Figured it was time to find some inexpensive help. right now im riding a 77 xs650 and it definitely needs some work. I understand that with new exhaust the carbs will need adjusting and cleaning. However, im not sure what to...

smoke coming out my left pipe and popping sound what to do cheers and do all xs 650 make a tapping noise in engine thks shane:) mines a 78

I have grey (not black) smoke at start up, and some miss-firing at low revs. Looking at the threads these symptoms point to low-level oil ingress. There are various suggestions: valve guide seals, head gasket, and the oil scraper piston ring. I am inclined to valves. This engine hadn't run...

Has anyone ever used Harley dyna mufflers on an X650? I found two dyna mufflers for $50 on CL. They are 1 7/8th outside diameter but I could need to put an upturn anyway so I would just use that in between the stock headers and these mufflers. Ideas? Thoughts?
