carburetors

Greetings all, First off, incredible site. Hats off to all of whom contributed to this site. I’m currently working on restoring XS360 1977. I bought this from my friend’s uncle. Though I wasn’t certain I was capable of restoring the bike, I couldn’t help leaving such an awesome bike...

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:

So, I bought this bike a few weeks ago. Replaced the starter motor this weekend, because I couldn't kickstart it to save my life. Now, the bike will start after a few seconds, but then will slowly wind down till it dies. After a little research, I decided the carbs needed to be cleaned. Took...

Has anyone welded in a new fuel cap into their petrol tank. Im looking at a round screw in style. Can it be done?

I got my 80 xs400 About a year ago. Got the carbs cleaned at a Yamaha garage immediately and it has been running great, until recently. The bike has always been hard to start up when its been sitting for more than a few hours. It usually takes me 5-10 kicks on a warm day, 10-20 in the fall...

So I'm pulling my carbs apart, cleaning em and rejetting them for the first time. It doesn't look as bad as i assumed it would, but I noticed some small cracks along the edge of one of the diaphragms. I tested it by putting a finger firmly over the oval hole on the front of the carb and it...

So it´s been running fine for a month but then suddenly became harder and harder to start when it´s cold or been sitting overnight. Now it is impossible to start. I have to roll it and engage second and it starts right away. No problem when the engine is warm either. Could it be the valves...

I ordered some new diaphragms for my carb, (could see through the old ones) its the ones where u reuse your slides and put the new diaphragm over the slide it fits and looks like a good product, while i was waiting for the diaphragms i cleaned my carb at work in an ultrasound cleaner just to do...

So After about a week of tinkering, frustration, blood, sweat, tears, the whole 9 yards, I thought I had it. I took apart everything I could with the tools I had available, cleaned things, check wires, fixed potential problem wires, everything I could think to do. For the last two days it hasn't...

Hey guys got a quick Q, my carb boots are old and cracked but look to be clean from cracks on the inside. But im having a hard time getting the bike to idle on the felt side. I know the bike will run lean if its sucking air on that side but will it keep it from running ir its sucking to much...

I have a 1980 sg and I'm having a hulluva time getting it started. When I bought it the guy had it running and I even took it for a spin. With the bike came an extra set of carbs with a broken post, but good for spares(except they are a different model?) When I got it home I took the carbs...

I just bought an xs400 and it has carb issues. It does run, but rough. Behind the idle screw, where the throttle cable attaches there is a flathead screw that looks like brass. What does this screw do? It appears to be all the way in but looks like it is an adjustment. I have looked at the other...

Hey guys, When I’m at a stop light and in 1st with the clutch in the bike rev's up until I let the clutch out and lurch forward into gear, then it idles fine. I’m going to tear into my carbs this weekend because I got new boots to attach to the motor. I’m going to clean them while I’m in...

Hey, I finally got around to starting up the bike today. She starts perfect on the first turn off the starter with no choke (new plugs and filters) but after about 5 minutes at idle she decided she wanted to rev to 3k and 4k if I don't turn her off, again choke or no choke she does this even...

Hey, Last fall along my travels a hair-line crack in my stock exhaust turned into a full disassembling of my left exhaust. It got loud :eek: . So...I just put on some new pipes, a sorta fits-all type, that still look good and are about the same size. Now while they do have some fiber-glass...

Well I just got my xs400 last week and am finding out the previous owner was an idiot. After building a new fuse box (he had the stock box rigged up with electrical tape) I got the bike running on full choke. If i moved the choke in.. it died, if i nudged the throttle.. it died. So now here I am...

I am really sick of pulling my carbs and trying to cram them back in. I'm considering dumping the air box and switching to pods just so its easier to put the carbs back in the bike. So question is what is the downside/upside of switching to pods and the downside upside to keeping the air box...

SO without my filters it runs amazing.... when i put the Pods back on... hesitates when i gun it!! i rejetted up and down.. all cleaned up... going to check now to see if there is a inner lip on filter any suggestions???

my carbs have been sitting for awhile and i really dont feel like going into them, so for about 200 i can get them rebuilt by someone else, or for 300 i can buy the flat slide kit from mikes, my question is, will they fit and work right? i know jetting would be different, but has anyone done it...

I noticed the price drop on fuel this weekend (~$0.55) and thought "yay, cheaper gas!" I fill up my baby and head out on the freeway, she starts getting bogged down about a mile down the road and I start to panic (please don't be oil). Pull off: nothing seems wrong. Start up: idle was low...
