what tuning is that ? all the jets are the same size in all 4 carbs, also the emulsion tubes, and all 4 airbox rubbers are the same as well !!!!

yeah i never found out what the mid (power jet) does ?????

the Mk2 does have a mid jet (power jet) #28 in the pic. CARBURETOR for Suzuki BANDIT 1200 2001 # SUZUKI MOTORCYCLES - Genuine Spare Parts Catalog (bike-parts-suz.com)

yeah they are fuckers for taking carb inlets/starter/genny off and sell them separate and still ask silly money for whats left.

some breakers ask way to much for an engine !!!! i picked up a complete B12 in a million bits for £500, the engine hadn't run for nearly 10 years but i do know the owner and bike with less than 30.000 miles on it, i did a compression test on the engine (it was out of the frame) and they wern't to bad, its now in my bandit as the bandit engine i took out has a dodgy gearbox !!!! it runs sweet. so good ones are out their. buying one with no history is a gamble but should be cheap.

I use dowty washers (seals) never had an issue yet.

yeah they are a great bike, nice and revy !!! look good with a few mod's as well.

not got the info you need but if you are genuine then good luck in finding him.

my guess is a sleaved down DR125.

sounds like its still running lean, try wrapping the filters a small amount with tape and take it for a run and see if the flat spot at 3500. if its better then its defo running lean.

yeah he has shares in the "ACME" bomb company

I have an aluminium shampoo bottle on mine !!!! polished all the logo shit off first the tube from the engine fits tight in the top but i drilled a few small holes round the top so it can breath.

yeah thats how i see it

i bought a cheap one for one of my bikes, it worked fine for a while and then it was intermittent, had to strip it and sort out the contacts under the barrel !!!

after staring at it for some time i can see how the whole thing works but it looks like the shock doesn't compress much !!!! but if it works, it works

haha

not in the exhaust in the inlet rubbers. the reason why i said is ive fitted some restriction washers to other bikes is, a 600 bandit rev's and rides just exactly the same BUT when it reaches around 80-85 mph it won't go any faster.

might be a long shot but ive fitted a learner restrictor kit to 600 bandits, they are just big washers shoved in the inlet rubbers with a smaller hole in the middle, im probably way off but worth a look, who knows whats been done in its history !!!!

have you got a gear linkage on your bike ? if so make sure thats free and smooth before you delve into the engine.

you do get a certain amount of popping in an exhaust on carb'd bikes on the over run, but its masked by the standard exhaust so its hard to here, but on a free flowing exhaust its more noticeable.

try and weeken the mixture screws off a quarter turn (in) and try it. and sounds like you have clutch drag !!!!!

always pays to double check cam timing

having an air filter on or off won't make much difference at idle with the bike stood still, the compression isn't the best but it should still run fine at that as they are all fairly equal. a balance might help if they are way out. but as Jonny said if you can, try another set of carbs.

what where the compression readings out of interest ?

I think the next step is to check the engine, do a compression test just to rule out a mechanical issue.
