Hi all, I'm after some more help & advice if anyone can help?? (and sorry for the long post but wanted to get as much info in as I could). I've got a standard MK1 97 1200 bandit, that I've done the 'Krazy Ed carb mod' on, 127.5 mains, 35 pilots, shimmed needles, pilots 3 turns out, float heights 14.5 & a 2" hole in the airbox. (It had a free flowing race can & K&N panel filter already on it). I've done a few of these in the past with good results, till now :-( On the first test ride it was running good everywhere with improved performance over stock, apart from a bad stuttering between 2k to 3k revs and you couldn't ride at 30mph without it stuttering (chugging along), but it was fine when you opened the throttle and gave it some, lifting the front wheel in first and second off the power no problem and reving/pulling all the way upto the red line. I tried everything, different settings on the carbs but couldn't get rid of the low down stutter (I changed float levels, pilot screw turns & even taped the 2" hole back up). I noticed a couple of the emulsion tubes looked slightly egg shaped (but only slightly) so I changed them anyway for new genuine Suzuki ones and it was a totally different ride. The stutter was more or less gone & you could actually now ride at 30mph when needed without the dreaded stutter, but now I have a new problem that I'm wondering if anyone can help with?? At standstill, in neutral if you rev the bike it now wont rev cleanly past 3k revs without coughing & spluttering upto about 5k revs and then its ok upto the red line, so 3k to 5k it coughs & splutters but everywhere else its fine inc on tick over. Also when riding it @ full throttle it seems a bit flat/hesitant between 2k to 3k but then takes off and is ok everywhere else. I've tried going less than 3 turns on the pilot screws to 2 1/2 turns but it then wont tick over properly, with the revs hunting up and down, from 500rpm to 1.5k rpm. (@ 3 turns the revs are steady @ 1k rpm). When you blip the throttle, the revs don't hang and they don't drop below the tick over either and it doesn't seem to get better or worse as it warms up, the carbs are also spotless inside. I've checked the plugs and they look OK (a bit rich if anything) and the outlet on the end can is slightly sooty but not really bad. So I'm thinking its running a bit rich if anything but it doesn't like me leaning the mixture and turning the pilot screw in, so that's threw me abit and now I'm lost :-( . Could it be float heights are wrong or would the needle heights affect this part of the running (thinking needles are more mid range)? Before I start stripping the carbs and changing things I'm after some of your knowledge and input to maybe point me in the right direction again .......... Thanks in advance :-)

Hello! I have a Suzuki 1978 GS550E. I got it from a friend and it needed carb work. I took it to a reputable shop nearby. Turns out I need a new rack to rebuild them because someone jbwelded one of the carbs and so it’s not usable. Long story short, he got carbs that don’t fit, they are for a 550 not the e version, or else some other slight difference that causes them to be misaligned and not fit. Since then we haven’t been able to find another set. I found a set of carbs for the 550E, but the year is unknown, so what I’m wondering is, does anybody know if any ranges of years of the GS550E carbs are compatible with each other, or if anyone else has any better recommendations! Thanks!

Hi, i am new to this.. (sorry i missed out on the introduction.. fair enough!!) i have a GS1000H from 1980 and my carburetors are used out. I would like to replace it. i found a refurbished carburator form a GS1000LN from 1979 that looks good. my question is, do they fit? my GS1000 has a Mikuni VM26SS and here are the specification from the seller about the GS1000LN: Mikuni 26mm GS1000 OEM carbs (pictures attached) Measurements : eng side : IS = 26.7mm OS = 33.9mm (aprox) Spacing center/center : left / rt banks = 75mm each + between 2 = 96.5mm thank you very much for your help and have a nice day

Hi guys i have bought a bandit 1200 MK1 that has gsxr 750 carbs (look like 1989 model ones with choke on side). The bike is running very rich black plugs running on tick over, bike will throttle up but cuts out after a while. Looking for advice on jet sizes it has 37.5 pilot and 102 main running on pods. Changed pilot to 35 and bike has correct mix at tick over but back fires and won’t rev just cuts out. All help accepted don’t have money to get it to a dyno at the moment.The 35 pilot jet I bought has no side holes the 37.5 has 8 would this make a difference

Hi Guys Another question, i have my carbs back on just want to clarify which one of the lines is fuel and which is vent as its impossible to make out in the manual from the diagram and i dont want to split them at the moment unless i have to. is it the ones closest to the front or the ones closest to the back with the spring over them? Thanks

Other post didn't catch any traction. Was curious for carbs what are able to be out on the 1127 engine and should I keep to the 36mm or possibly upgrade to the 38mm? And if so what can I look at from other bikes to swap onto this one? Any help with carb related info is a plus. Trying to keep cost down as much as I can.

Hello, I want to know if anyone has experience with the base jetting, when swapping out the carbs on a gsx1100 with a pair of bst36ss from a gsxr750. my gsx1100sz has no modification other than a free flowing racing exhaust. regards Morten

can any one tell me the difference between the 5D76 needles used in the Mk1 Bandit 12 and the 5E60 needles used in the 89 GSXR 1100 (UK Spec BST 36 SS)...both are used with the O-8 needle jets (emulsion tubes) cheers John

Hi everybody, I've never started a new topic, so please feel free to take the pi$$. I'm trying to fit a set 38mm Mikuni carbs to my Sladsibe 1100 0 So I thought I'd get them a set of new emulsion tubes from Robinsons. However, when they arrived, they are completely different to the originals. The originals have a series of holes down the sides (like every other set I've seen). The new ones are solid tubes. Also the holes down the centre are tiny compared to the originals. The needles don't fit down them. I contacted Robinsons to check, & the part numbers check out, but they are looking into it. The carbs were suppose to be off a standard GSXR 750 with airbox. Anyone any ideas ?

I have a set of 36mm Mikuni carbs on my Bandit 1200 and am rebuilding the bike which will have a turbo. I need to restore the carbs to standard setting as they are fitted with a Dynajet 3 kit. What are the sizes of jets, needles, emulsion tubes, etc that I need and where is the best place to souce these? Cheers.

I got the bike in December it was never running 100%, after clening the carbs i discovered the previous owned had put a DynoJet kit stage 3, going from 115 main jets to 165, huge jump, I've been trying to do a trial and error since the bike is running extremely rich and my spark plus get fouled really fast. I tried going down to 150 main jets, and 140, still running like shit. I want to go back to 2 over on the main jets, i want to know if Suzuki goes up 2.5 or 5 increments? stock is 115, should i go to 120, or 125?
