'03 Blast won't start

Well I bought an '03 Blast knowing it had issues with starting. I had seen the bike just a few weeks before and had taken it for a test ride so figured how bad could it be. Enough said...!!

So here I am now totally miffed on what could be wrong with the Blaster.

Here is what I have some so far and the outcome of my efforts.
  • Swapped out the gas for some high test by draining the tank and carb... no difference
  • Checked for spark... got plenty
  • Checked and set timing using the static method... no difference
  • Totally disassembled the carb and gave it a good bath. Sprayed out all the jet holes and reassembled... no difference
  • Replaced the jets with the renowned 45/175 combination... no difference
  • Replaced the enrichener...no difference
  • Drilled the mixture plug out, took out and cleaned, then replaced making sure I had all pieces in right then set at 2 1/2 turns back from bottom...no difference.
  • Checked the Das Boot(OEM) for leaks and cracks then with carb installed checked vacuum; got plenty....no difference.
  • Tried starting the bike with the gas cap off... no difference
  • Jumped the kickstand and clutch relays...no difference
Some things I did notice:
  • I am getting voltage at the enrichener plug but with the cap and guts removed I am not seeing any movement on the enrichener plunger. I didn't on the old one either; that is why I replaced to begin with.
  • The vacuum piston is not moving up and down during my attempts to start.
  • The bike does sputter and fart while trying to start but never gets up enough momentum to get itself running.

I know there are many Blaster gurus on here so figure I would hope to get some insight on this stubborn beast. I have been around bikes many many years, even rebuilt a few and never had this much fun.

they are known to have vacuum issues, its likely your blast is leaking vacuum and the carb isn't getting its mix.... Check out this site... http://badweatherbikers.com/buell/me...64/150578.html

Been all over the Buell sites and still no luck. I checked the rubber cap on the side of the carb. Its good. I have plenty of suction at the air cleaner if I put my hand over the carb.

Have you tried taking it to the pro's to see what they can do?

I think at this point - considering how many different things you've tried and didn't work..

I'd just bring it to a mechanic.

It's probably the best advice at this point. Might as well save all that time and frustration
