the bandit is running on 3 cylinders and smoking a bit. I've checked the exhaust temps with a wet rag, the #4 exhaust (right most) is cooler than the rest, the other three hiss, it just slowly evaporates the water.
I've tried changing the plugs, I've tested the coil's resistance (both similar). I've cleaned the float bowl and jets of the carb for that cylinder, they seemed clean anyway.
I think I last checked valve clearances around 10,000km ago, the manual recommends checking them every 6000km (but last time I checked them at a larger interval, they were ok). So I'm planning on draining the coolant, pulling the rocker cover off and checking the clearances.
I checked the compression, all the cylinders were about where they were last time I checked it (around 110psi which is admittedly low, but I'm not sure how accurate my gauge is).
The only thing I can think to look for is to see if the valve clearances might have gone way off, but then wouldn't that affect the compression test?
Maybe I've missed something in the carbs? I had a look at the diaphragm in the #4 carb today and it looked ok.
I think this might've started at a trackday earlier this year. I remember the engine sound changing at one point and finding a piece of broken exhaust mesh stuck in the end of the muffler, so I thought the difference in engine noise was because of that, but maybe something else has happened inside it?
Any ideas?
