exhaust

Just got some universal slip on mufflers. It came with the pictured adapter. If I don't use the adapter, I can't seem to tighten the clamp enough to secure muffler on the header. If I use one of the 3 concentric adapters it is very snug but still leaks at the adapter rings S joint. Do I use some...

I got these (http://www.dimecitycycles.com/vintage-cafe-racer-caferacer-bobber-brat-chopper-custom-motorcycle-exhaust-parts-17-inch-reverse-cone-megaphone-muffler-80-84030.html) from dime city cycles I don't plan to change the air filters will I need to rejet? Would that be up on the main, the...

I need to remove the exhausts on 2 different Maxims. It's tricky because the crossover tubes underneath are rusty, and it's hard to pivot everything to remove it because of the head studs, and the studs on the rear pegs. I've tried lots of whacks with a wooden broom handle from opposite sides...

Hello Guys, First of all sorry for my english, I dont practice it often. So Ive changed: 1. My stock air filters with k&n style filters with H pipe 2. Stock exhaust, with shorty mufflers 12' Attaching only one photo that I have in this computer. Im at work. The problem is that after a...

I need to swap out one of my headers for one that doesn't have a dent in it and I was wondering if I can reuse the heat wrap again? I was thinking to soak it in water again to gain some of ots flexibility back on hopes of wrapping the new header with the old wrap. The wrap is only 1 year old

Hey everyone, here is another thread about having problems with an XS400 :doh: Anyways i'm having 3 major issues. 1. No power below 2.5k 2. Slight hesitation at around 7k 3. Coughing and no power @ WOT (no matter the RPM) I had the carb ultrasonically cleaned as I was having worse issues with...

My xs400 has 2 into 2 'sport' exhausts on and I was wondering if I created more back pressure, would it run richer? I have a little lean issue. The carbs are all stock jets. Would a free flow exhaust cause this and can I fix it with added back pressure?

anyone give me a pointer to a supplier of exhausts in the UK - or do I need to order from the US ?

I was thinking of using a muffler hanger with a swiveling strap and drilling a hole at the "x" to attach the strap. Think that will work?

Can anyone suggest replacement mufflers for a 1982 XS400. If so, can you provide a supplier.

So I am riding the bike now and when I get up to about 40mph a scratching noise starts to happen and the faster I go the louder It gets. It's kind I hard to describe so I will post a video shortly. This didn't happen before I put the exhaust on (or maybe I didn't hear it). I shook the exhaust a...

Hey everyone! I am sure this thread will rattle some of us, but I gotta ask... ...are your headers blue? I was just looking at the Sanglas thread, and the picture of that bike from the magazine has blued pipes!:confused: My understanding is that these double wall pipes should not blue, and...

I have been planning on working and making mods to my bike but I haven't found a lot that In can do performance wise for the 400cc models, but there are parts for the 650cc. Any idea if the parts would fit my 400 or where i can get performance parts?:shrug:

I just picked up the emgo shorties and know that they are an exact fit to the stock header but Ive seen those universal muffler reducer sleeves online and was wondering if they actually work or are just a gimmick. Anyone have any experiences with these? Should I get them?

Hi all, I have a dent right in the curve of the header pipe heading back to the exhaust. (looks like the PO ran a curb or something?? :yikes: ) I've done some googling and found some have success with pushing dents out of their pipes by removing... filling with water... ensuring no air...

ive owned my 77xs400 for about a month now and have put around 500 miles on it already. hopefully this has just started, but i noticed there is a little puff of white smoke that faintly smells like oil when i goose the throttle sitting still. Also there is a bit of backfiring/ popping around 3k...

I'd like to buy new exhaust, preferably more oriented towards performance, and was wondering what you guys liked, didn't like and would recommend. '77 XS400 Max Price - $250

I recently installed exhaust baffles, which were missing, but the left side baffle doesn't set in the muffler all the way. It is slightly too wide (or more likely the muffler for some reason is slightly too narrow). Regardless, I was wondering if anyone had suggestions to make it fit? I tried...

Hello everyone, I am new to the site and a new motorcycle owner. I have a 1980 xs400 special with 5600 miles that I just picked up a few weeks ago as my first bike. I've taken it for a few rides and it seems to run good. The only problem I've found, and I don't even know if it's a problem, is...

one of the guys had posted about how on one side the flange that has the gap and holds your pipes on, wouldn't come off bc it seemed to be bent down.. well i had that problem too, my inside bolt was bent inward and down.. finished putting one pipe on, then decided to try and bend the other one...
