I just bought a 2000 Buell Blast Off a friend who I harrased because it only has 3500 original miles on it... I know, a shame. Anyways I have two major problems with it so far. It has sat since 8/08 outside in sunny northeast PA. I drained the gas and put in a new batt. and new spark plug. I also thought that the two black tubes by the left foot peg that one was fuel and one was oil. Well I was wrong, one was oil and one was something very dark with some white in it, and only about a table spoon worth came out.... any ideas about that???

Also now when the key is on and I sit in the seat the electrical shuts off (EVERYTHING) when the seat is off I push around on everything and depress the suspension and it won't do it, only when the seat is on.

My number 2 problem is that I can get it to start if I let it sit for a couple of minutes but soon after it starts (less than one minute) it will come off high idle and then die. I then can not get it to start unless I wait about 5 minutes. It will just turn over and over and over occasionally firing, but not more than twice.

So I guess I have 2 problems and a question.

I am going to pull the carb off this weekend and spray it our because it sounds like something is stuck shut. I pulled air cleaner cover off and everything is SPOTLESS.

Thats all I can think of right now, let me know what you think!!!!!!
THANKS!

Problem #1 is a electrial problem.
My bet is the seat pan is shorting out the battery when you sit on the seat.
Make sure you have the battery seated all the way into the battery cavity.

Problem #2 is most likely a clogged pilot jet.
The carb needs to come off and be disassembled and cleaned.

Check the Blast Knowledge Vault for tuning tips. Since you have it a part, you may as well rejet it so it runs better.
The jets will set you back about $10 or less.

The reason it dies is that it has an auto enricher. Basically kind of an automatic choke. When it closes the carb goes lean and the motor dies due to the clogged pilot jet.

BTW, you will probably get more responses to your questions if you post them in the THUMPER Forum.
