carburetors

Hey Guys, I'm back in the garage after I just finally got the engine to kick over on its first kick. Runs like a champ and has a ton of compression. Figured out it was a timing issue under the timing cover and adjusted it accordingly to the crank and its positions. Anyways, I own a...

so i have done cleaned these carbs 2 times boiled them once and also had them professionally hot tanked at napa so i know they are clean as hell inside, no the air fuel screw is 2.5 turns out and it will run but at a idle it dies out, also i looked up the carbs and they look like the bs34cv...

Has anyone had success modifying the stock or fabbing a new H-Pipe that pulls the filters closer to the carbs but maintains their cross-flow and the venting from the crankcase? Effectively cleaning up that 'triangle' but maintaining the function of the big stock H-Pipe. I think Kingjetpack...

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...

SO I want to get some aftermarket cone filters, maybe some K&N's for my bike. The stock ones looks like garbage. What are the best aftermarket air filters, and are there any that wouldn't require an upjet? If no, what are the relative jet adjustments that have to be made? I'm new to this!

Need some thoughts on jet sizes with an open exhaust with full length reverse megaphones..stock XS400 engine...Spad

I was just curious how many of you guys subscribe to Motorcyclist magazine? I have for a couple years now and I decided to write an article for the "Me and My Bike," segment. The editor actually got back to me and said he was going to try to get it in an upcoming issue! So if any of you have a...

Okay when i first got it ran but now wont run engin will turn but it doesnt start any ideas this is my first bike

I have a 78 xs400e that i converted to one carb. I just cleaned the carb and put if back on. Carb is stock bs34. When I turn my petcock to prime there is no fuel flow down the hose into the carb. Petcock works fine and drains when disconnected from the carb. Is there an airlock in my carb...

Hi all, I have an interesting issue......I have a 1982 xs 400 special.....japanese model. It sat for almost 12yrs so first thing I did was take carbs off to clean. this is what I believe I have....will post pictures as soon as I can. bs/38 Pilot jet is stamped 145 I also have a set of...

So I've finally got my 1981 XS400 back together, but it still won't run correctly. We put the carbs back on after a mild cleaning (because I don't know how to correctly do a full tear down and clean; if I did, I would definitely do that), and the bike will start and run with a shot of starter...

hello all, i have a 77' and was wondering how easy it was to convert to the vm34 slide carbs? I've read some threads on here how it's possible to get the jetting to work, but i was curious if the newer carbs bolt right on or if there is some fabrication involved? my carbs are pretty...

Hello, New to this, but hey ho! Basically my good old Granddad got bored of seeing his completely standard XS400 W-reg sitting in his garage so he gave it to me for my 19th birthday, legend! He gave it to me as a non runner, however I have rebuilt and cleaned the carbs, cleaned out the tank...

First off i would like to say hello to you all. I have a 1980 XS400 SG its been sitting for about 4 years untouched in a shed. last week i tried to start it up and it was dumping gas out of the carb so i had a friend check it out and pressure test it, and fix the leaking issue. he replaced a...

my carb is leaking on my xs. its pouring into the air filter how do i solve this? is it the float?

I have a 1981 XS400 Special. It came with two sets of carbs that the previous owner assumed were the same (and so did I, due to less than due diligence during my purchasing process). I've since noticed some subtle differences and I'm hoping someone can identify which set of carbs are the...

Hey guys, this is my first post. I've read dozens of threads on this, but I really am stumped on this one. I'm from Manitoba, up here in Canada eh. I bought this great '82 HS this winter. Price and mileage were so good, I didn't care if it ran or not. Only 19,000 kms. Once I got it home and...

Ive got my carbs torn completely down ready to soak but have a question about removing the main jet emulsion tubes. I know on other CV carbs they come out from the bottom up through the top of the carb. Before I try to knock mine out I need to know if this is how they are held in on these...

so i bought a 1979 xs400 thats been "messed" with already, the PO put on a 2 into 1 exhaust and told me he had jetted it, it was running so rich that the plugs fouled black within 50 miles and it would not start on choke and bogged down at around 5k rpms, just for the heck of it i put on pod air...

Building a SOHC motor, lighter crank, gsxr1100 pistons (500cc final displacement), and megacycle cam, some headwork. Im thinking 36mm carbs, still need bike to be streetable. Any opinions?
