so when my bike sits for to long i get varnish in the carb,and it dosent want to run,so i take the carb apart clean with carb cleaner and air works great except for the last time i did it.i think the vacumn diphram-needle is shot its sucking air.                                                               

i would love to give you some info on it, but i dont know too much about carbs. the only thing i do know is that when they dont work it sucks!

im sure youre gonna get alot of advice but u can do it without air take your main jet pilot jet out spray them out since u have them out take rest of it apart let it soak,when im done racing at the end of day i turn my gas off keep it running till its empty i run vp u2 it will eat your carb up

when you get concrete in your carb let me know ok, lol

you need to order a carb kit so you have it next time you need to get it running. the soft parts do not take well to sitting. just like a fuel pump diafram with the lever in the same posistion for a long while makes a future tear. 

Before you store it buy and mix "sta-bil" fuel stabilizer in the take and run it until you are sure it gets to the carbs and you will not have no trouble. Or just start it once a week and let it run for about a half an hour.

You also need to get some stuff I believe called the puffer. It is sprayed directly into the carb and coats everything. I use it on my boat and it seems to work, use it along with the fuel stabilizer.

It's called fogging oil that is sprayed right into the cylinder block through the spark plug hole. I've never used it on my motorcycle but I have on my boat also. It keeps the cylinder walls from rusting over long storage. I've always spray it in the carb air intake while the boat is running until the it kills the engine then it is sucked into the carb good then I do the cylinders and thats the last thing I do. 1. full tank of gas with sta bil 2. spray carb 3. spray cylinders.
