Woohoo! Well, we saved money in having to BBQ an entire cow and ice up a couple of slabs of beer for the KSRC Brisbane contingent, as Jeff got the bike going today.

Last week he took a week off work in the pretence of using it to work on the bike, not that a lot got done! He gave it a bit of a general cleanup, checked the spark plugs, battery etc, and that was about it. Today he applied some Aerostart, and then she started, so he shut her down and let her be. He headed off down the servo to get some fuel for the mower and some for the bike, tried to start it again, but again she wouldn't start. In the process of taking the fuel tank off to check something, he noticed that a vaccum valve leading from the fuel tank to the carby wasn't connected. He reconnected that back up, fuel tank back on, started her up and she happily started again.

So, now that we know the bike can run, can the mechanically minded of the forum suggest what maintenance should be done for a bike that has been sitting for 2 years? He has bought some carby cleaner and will clean the carbys next weekend, will replace the air filter, the spark plugs have already been replaced, is going to change the oil and brake fluid. He thinks that there might be a slight fuel leak, which is what Hammer suggested might occur, apparently commonly caused by a sticking carby float. Any other suggestions?

That sounds like the ticket, Esie. A complete disassembly and clean out of the carbs will do wonders for it. Just make sure that you keep the carb cleaner away from any rubber bits, (or plastic bits of the bike, such as the windscreen or headlight!) as it is nasty shit and will eat them! Carb diaphragms are really touchy and cost lotsa $$$$$$$$- $600 for my GT ones. Be really careful not to tear them in disassembly too. A valve clearance check and carb balance would do wonders too.

I cleaned my diaphragms and other non metal bits with Nulon carb cleaner and nothing happened. I'll avoid it in the future just in case, but it's not as bad as people make it out to be.

I did the same on my ZZR1100, before I knew any better- one of the diaphragms stretched and the only way to fit it was to freeze it first to fit it in the recess in the carb body. I guess it depends on how long the stuff is on the rubber, but there are safer ways to clean the diaphragms- I now use very dilute (in water) metho- cleans em up nicely- did my GT ones yesterday- they were covered in oil.(blowby) If you have a bit of clear junk plastic, spray some carby cleaner on it and see what happens- I accidentally sprayed the lens of my bicycle torch- went opaque and useless afterwards.
