Im about to ultrasonic clean my carbs but since tha cleaning bath is so small ill have to disconnect the 2 carbs. Is there any easy way for this or will i end up in a broken or leaking fuel T? Plz help!

I installed a pamco with e advance on a xs650 that was running with a kickstart battery using hough PMA and battery. It had a boyer before. Battery melted and i reverse polarity on the batterh and fried the ignition. I re wired it all and now the bike starts and run no battery but i camt get...

I have been reading allot of stuff on carbs and jetting and it seems that these carbs or at least the BS34s -38s have issues with most people on the xs650 mods such as pod filters and custom mufflers seem to have a drastic effect on the the carbs in some way shape or form.:doh: I am aware that...

Ok so as some of you may know, I've been fighting to get my bike to idle properly. Last night it started coughing back out of the air filter on the right side. Pulled the carbs today checked float height and idle jet, both clean and in spec. Start it up, chugging along ok with choke. I then...

I have a very clean 1983 xs650 with 7400 miles. Purchased it early July of this year. Bike had sat for a number of years unused and the carbs were synced and cleaned by an independent mechanic right after I purchased it. It has run 1200 miles flawlessly until today. Started bike fine as...

Ok guys, I'm having some serious headache inducing rage instigating trouble trying to tune the vm34 carbs on my 71 Xs to a strong idle. I've read both the mikuni manual and the other member written manual everyone suggests. I've adjusted the cam chain guide, valve lash, and timed the bike...

that is the question.:) How much pain do you wish to experience !..... I inherited my 79 Special which came with pod filters and have struggled for 2x years to get the damn bike to idle properly when hot. I have had the carbs off and cleaned, adjusted and overhauled them at least 8x...

Hey guys. Just curious what size Mikunis are you running on your 750 conversions? Just wondering what everyone is doing and opinions. Thanks. Chris

I've had my BS34 carbs apart for a while, but only just recently noticed some surface aberrations on both sliders. I probably should replace them yes? Also the rubber part feels pliable and I don't see rips, but they seem bent kinda funny - partially from them sitting outside the carb (in...

Ok friends. My stock 1980 has been running rough, and it has been progressively getting worse. I've cleaned the carbs good and changed the spark plugs and it's still doing the same thing. Most of the time it will run pretty good and then after 20 minutes it starts sputtering real bad in first...

well I've searched for a couple of hours or so and not found anything very helpful on this topic but maybe I'm using the wrong search criteria. I was wondering if there were any reasonably priced alternative carb options for the XS ? that don't require extensive machining,... frame...

Hi all advise and wisom needed. This is the situation just got my rebuilt engine Thanks Smed Speed basically everything inside is new plus it a 707cc now not a 650. I am going to fit the standard Mikuni 34's do i need to re jet the carbs I have fitted strait through reverse cone cafe racer...

Hey gang, Just got myself a new XS! An early model too, 1971 xs1b! It's got its problems, and I need some help to find solutions. So lets start from the beginning... I bought the bike from the third owner. He says it was the perfect runner, started first kick every time, and the strongest...

ok i know i shoud know this but i just cant remember, whats the diffrence between vm slides, 2.0 2.5 3.0 and will 3.0 slide work or do i need to order 2.5 slides

Well the 77D I was working on is now going to take a back seat to a '78 Special I bought early on in my accumulative activity and never really touched except to add in a new Mike's glass fuse kit. (I know better now). It is very complete, I have a burgundy tank for it, looks like the side panel...

I recently purchased a 1981Yamaha XS650 Special. The bike came with a bunch of extra parts and included a set of Richard Getman billet carb connectors. I would like to install them and would like to know what connector/gaskets/hoses are required. The bike has the stock carbs. Will these even...

Hey guys, So I snapped a throttle cable two weeks ago. I ordered what I believed to be the correct cable from mikesxs... The cable housing length was slightly shorter than what was on the bike but it seemed useable, except that the the length of the cable was too short, thus not allowing the...

Hello Everyone, please see my new ride. Quite the find and I am so incredibly happy. Have done a few long weekend rides and cant seem to keep from riding it. I have much experience with bikes but this is my first XS. The bike from what I can tell is mostly original even down to most of the...

This may or may not be related to carbs but I'll throw this out there. I've just finished a rebuild of a stock 72 motor. It has 76/77 carbs on it which had one size up on pilot and one size on mains which ran fine before the rebuild. Since the rebuild she is running rediculously lean. She...

Hey Fellas, I have been reading throughout this forum for about a month now and I haven't been able to find my issue listed. I have checked the carb guide and read through most threads. I am not very mechanically inclined so please break down your answers. I purchased a 74 xs650 with only 6,100...
