As far as I know, the engine has never been apart and has 22000 + km's. It has been compression tested at 120 psi on both cylinders. I've recently had the carbs cleaned by my local shop and set the float height to stock 13mm. I had to replace the float valves as both were sticking with aftermarket parts (I assume from China) but OEM are on the way. I also had to replace a bad rectifier and connecter on the wiring harness. Running on 91 octane (the highest pump gas available here), new spark plugs and new Mottobat sealed battery.

Another thing, the bike is now getting harder to start...30 kicks last night. When cold it's a b*tch but starts up first kick when warm. Could this possibly be a symptom of the dreaded NSR crank seals going bad?
