you are bang on their, i found the problem mostly with the 600's though, still had a few 1200's as well. a can't remember the amount of 600's ive had this problem with but its a lot !!!!! no matter how good you dry and clean them even leave them for a week and they still wont work ?????? and they are new plugs that just got wet (with fuel) bang another new set in and it runs like a dream, go figure

i was thinking about the swingarm end float adjuster, could the shaft be seized to it ? it might be worth taking the lock ring off and see if the spindle will screw out. just a thought.

should of completely drained the tank and got all the old fuel out, the bandit coils are pretty reliable. my guess its a fuel problem. the bandit carbs are getting on in life now and ive seen countless problems with the float valves, the rubber tip wears and fuel can leak in causing a rich mixture and lumpiness but runs good at speed as the extra fuel is being used. check the colour of the plugs.

i used the OEM sprocket carrier from the GSX ET wheel in the B12 rear wheel, fits perfect and is further in that the bandit so the chain JUST clears the frame. you will need a front offset (expensive) sprocket too !!!! a 530 chain should just about fit but a none O ring is slightly thinner or go down to 525/520 chain kit.

blasphemer

thats shocking

water has a skin so could mask a leak, you need something thinner.

what about a GS/GSX 750 engine to keep it old school ?

ive used them cheap Chinese RFY piggy back shocks twice now, OK they are not the best but they do a job and all for £40. plus they are height adjustable and if they are no good you havn't lost a fortune this is them on my inazuma project.

i think the all depends on how bad they are. ?

one thing i do know is, grinding 16 valves in is the worst job to do on an engine

we are talking about (i think) a 40 year old engine, if he gets a %100 seal with grinding paste then i'll show my arse in a shop window. I better go and give my arse a wash and a shave now ive said that !!!!

you can't expect two metal surfaces held together with a spring to be 100% sealed especially the exhaust valve seat, as i said petrol is very thin and can leak through the smallest of gaps. if it holds for a short while before you see a damp patch then you have a pretty good seal. im only going on my experience

does that include my BROWN one ?

yeah, i do know that Suzuki where struggling with sales in the 90's so they had to use what ever they had to hand and make the rest on the cheap, hence the bandits that helped them out of a rut. i know a lot of you guys dont like em but they sold thousands of them and it helped save the company. i think they are a great bike but thats just my opinion.

when i was in the bike shop i just used the degreasing fluid out the the cleaning bath, seemed to work well.

we know the bandit is a parts bin special and being the "unicorn pre production bike" they would of used whatever they could lay their hands on till the final setup was reached, thats my thinking

try a new plug, and check the cap for damage.

the mk1 carbs have just 2 screws holding the float bowls on, but if you take them off in situ the plastic float frame drops out. not easy to refit. best with the carbs out and upside down.

using petrol can give you a false reading, its one of the thinnest fluids about and can seep past almost any gap unless their is an O ring holding it back. if you do use petrol and it doesn't leak straight away then its probably ok but if you leave it some time you will see damp spots

i use 6mm dowty seals on mine, never had a leak yet

how do they check that ? the mk1 and mk2 engines share most of the engine components

pretty much the same wraith.

it would be a good idea too while the top end is off, you said its burning oil that could be the rings as well. after you measure the piston to bore clearance and the ring gap and they are in spec, don't rule out the oil control rings.

are you putting new rings in ?
