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.

did you check the condition of the diaphragms ?

did you have the vacuum pipe plugged when you had the tank off ? and did you have some sort of fuel supply as its running ? got to keep the float bowls full at all times

rev's that hang is a symptom of an air leak or a lean mixture when it comes to carbs.

first off set the idle when the engine is at working temp. if the rev's are hanging and then dropping is sounds like its running lean (to much air), have you tried the mixture screws ?

yeah seen them, don't know how good they are though !!!!

if you mean the Mk2 bandit clocks you will need to rig up some sort of speed sensor off the front sprocket cover, and wire the rev counter to an ignition coil. if you use Mk1 clocks then you can use a speedo drive from the front wheel.

I think the GSX swinger is a tad longer but not sure ? but the pivot width is the same. the wheel goes in easy but the sprocket carrier needs machining down to get it lined up. not got the bandit engine in yet though.

I'm building a GS1000 based project atm, it has a GSX1100 swinger that fits straight in with a bandit 600 wheel.

I think it might help if we know what bike

I disconnected the hose to the calliper on one of my bikes and took the top part off, then made a plate to tidy it up, if you take the top off the antidive their is no fluid just a little plunger thing, but the plate just tidy's it up. zoom in on this pic. or click to get a clearer view.

she's already mentioned it Toni
