When the bike seems to lose power, pull over and carefully touch the exhaust downpipe from each of the cylinders - if one is cooler than the other then you can determine which is not firing. If all ok then i'd look toward the coils, and if no problem there then check the air-intake for the field-mice/hamsters/gerbils etc  (i once had an intermittent blockage here with a rag in the airbox intake, so it certainly does happen...).

Did you check the fuel bowls in the carbies? I'd say there is a god chance they are half full of water and/or dirt.

Yeah, I got water in the carb of my F650 and it caused very erratic problems like the ones mentiones here. The little drain hole inside the fuel cap got blocked.

If the gas cap is anything like the KLR gas cap then the little rubber valves might have gone bad. Have you tried riding it with the gas cap off or lose?>

Problem seems to bee solved. Thanks guys.
I checked the breather hoses, no kinks
I checked the air system. No mammals or other stuff inside.
I checked the sparks. Looked good.
Fuelfilter in the fuel tank. Clean
Tanks gap. Mmm breather holes might have been a bit clogged. So I soaked it in water for a day and the gently blowed it clean.
Carbs. Gave the screw a few turns and a stream of clean fuel leaked out. So no problem there, the other carb didn’t though. It dripped verry slowly so it must have been clogged. So I hooked up a hose and inhaled. Bloody hell fuel tastes horibele but after that it worked ok again. Could have been some water inside or some dirt which became lose and flushed out.
So the bike runes ok now . Thanks for the tips.

Glad I could help Luuk. Seriously though, it's no good just emptying the crap out of the fuel bowls through the drain plug, because you won't get it all out.
Take the carbies off, and remove the fuuel bowls completely and give them a good clean. It's almost certian there will be more water or some grit, dirt and corrosion in there.
Unless you clean them out properly your problem will recur again.

A compression test requires a compression gauge like this one:
It allows you to see if a cylinder has a healthy level of compression. Compression is the only thing that makes you bike go fowards. Without it everything else can work and your bike will still not run. It can indicate piston ring weat, valve seat wear, etc. I would not say it is essential to finding your problem, but if you did one and noticed that one or both cylinders were down on the compression, it would warn you of future problems and maybe explain why your bike is more likely to loose power.
Have a look here.

Check the tank breather - if it has a blockage or wasps nest in it, it will create a vacuum over time and use; as soon as you stop the bike the vacuum will normalise and will allow you to continue until the vacuum is again created. Another thing that can happen is pinching the line when you incorrectly route it when replacing the tank.
Just a VERY common complaint with a VERY common solution.
Let me know what you find if its anything different.
Cheers
Ian
