carburetors

New xs400 owner here, my first bike! I'm a bit of a hobbyist mechanic but I've always wanted an old Yamaha, I just love older Japanese bikes. Anyways, the owner was a super nice guy who let go of this bike for $300 and a chicken sandwich (I got the guy fries too for giving me such a killer deal)...

Hello everyone, Long time no see/post. I have been away in a career for a bit, and thankfully haven't run into troubles with my bike (80/81 xs400sg) nor really needed to break into the carbs...until now. It turns out, one of my adjustable needles snapped because the prior owner had replaced...

I'm pretty new to bikes and am learning as I go. Bought the bike at the end of December and haven't had the opportunity to get it going until now, with the warm weather and all. It was running in December when I got it and I could start it with the kick start. When I replaced the spark...

I'm in the process of rebuilding my peacock as described in out wonderful how too. I have found however that I have no in tank filter nor hosing, just a pectcock with its oval ring. The manuals description is quite vague and no exploded view of it. Internet pictures seem to be just a hose...

Now I know this is an xs400 forum but I don't know anywhere else to ask , I have been fixing up an old enduro (ct1 175) it's a 1972, fun bike anyways , it runs fine until I've been riding for about 10-15, minutes and all of a sudden it will just sputter out and die , it won't start again unless...

Skip this first paragraph if you don't want the backstory and only want to help me with my problems haha. My uncle gave me his 1980 XS400. I was beyond excited but am and have been working on my 79' GS750 for about 4 years now. As that project is nearing an end and as I've collected several...

I did a re-jet on my carbs because the slip-on mufflers I installed have almost no baffling. I took the pilot jet up to 45 and the main jet up to 140. I also got some basic pod filters on the h-pipes. Upon re-installation I set the petcock to prime for a min as I read to do. This must have been...

Hi Everyone, I'm still pretty new to working on bikes and need a little help. My intake boots are cracked on my '78 XS400 (2L0) and I need to replace them. I was looking on eBay and found these...

Hey guys, I've been trying everything to get the carbs on my xs360 running right. The bike was running too rich no matter what I did, especially in the low and mid range. I did a bit of digging, and I found some talks on a honda forum (blasphemy!) about worn needle jets. They were saying over...

I have myself an 82 xs400 Seca, i have 2 of them, been piecing them together to make one beautiful Seca... anywho finally got it to start and run and idle yaayy, but last time i rode it for 1.5 miles it started to bog down and when i start to move it seems to loose all power and shut off only...

Hey guys, I have the XS400 R Seca with the "Gear-Looking" (as opposed to the football-looking one) and my gas cap is broken on the outside. I can still open it to fill it, but some of the "gear teeth" are missing from the outside. I wasn't too concerned about it until I ordered a used tank...

I bought a 1989 XS400 for 450 dollars after it sat in a barn for a few years. I replaced the air boots on the carb and put new sparks plugs in it. Also drained the gas and oil and filled the tank with good gas and gum out full system cleaner. It idles now but it goes up and down and has 0 power...

This is my method for mounting pod filters onto the rubber intake runners allowing for more clamp purchase to the rubber components. (I Can't get photobucket to upload images properly so just follow attached images by step) 1) I took a spare intake cross over tube and cut the flanges from...

A while back while I was cleaning the carbs, I noticed the pilot jet was stuck in there. I didn't want to press the issue and create any problems so I left it in there. Afterwards, I synchronized the carbs with vacuum gauges and got her running pretty good. All of the jets in these carbs...

A month ago i bought my first bike a yamaha Seca xs400. The guy told me when i bought it he had the carbs completely rebuilt, new battery, new spark plugs, and flushed out the gas tank due to it not starting. When i bought it it seemed it ran and started just fine until i got it home it was just...

mostly for my own edification, want to have these all in one spot... might help others clean carbs / tune carbs Carb Part Photos Cleaning Guide: http://www.thegsresources.com/gs_carbrebuild.htm Guide: http://www.amckayltd.com/carbguide.pdf Walk Through with photos...

I want to check my 'theory' of what is wrong with my engine before I clean the carbs (yet again) 1) Engine is quite hard to start, especially when warm 2) Idle is poor and will die after a while 3) If i pull RHS spark plg from engine while idling it cuts out completely 4) If I pull LHS...

Pulled carbs back apart to reject and clean should have put them in bag I don't know what those bugs are that like to live in bolt holes and such. Any way with my old eyes it looks like i have 135 mains and 155 pilot jet does this sound typical. I'm gonna start 1 up on main and see what I can do...

Hey guys so I changed my car jets to 142.5 mains 42.5 pilot and set the idle air to 2.5 turns it has pods and a high flow exhaust. Bike runs better now and has way more power in the low revs, when I changed the jets from 149 and 46 I cleaned the carbs since they were out of the bike. Now I...

I have an 83 Maxim. So the box just behind my carbs is my air filter box, correct? What about the "filter" below it shown in the picture. Is that also an air filter and if it is not, what is it? I see a lot of bikes in this forum with "pod filters" replacing the box. They do look cool but...
