When I purchased my Blast, it had a D and D exhaust and sort of jetted carb. I finished jetting and added Dan's Superboot and Intake system. Still had issues with staying started and keep the Carb on the manifold (fart and blow right off). I have changed the Boot a few times and played with needle position and jets. Still no success. Recently I changed the whole carb out and put on a normal CV with manual choke and fuel pump (dont think its called a fuel pump). It starts and stays started, just seems like it takes forever to warm up. When you really crack the throttle, it bogs so bad. It almosts works normal if I leave the choke out a little while riding. Once in a while it'll still blow that carb right off the manifold. Where do I go next? The local Harley dealership wouldnt touch it, they said I wouldnt want to pay that much to get it fixed. I had a different local shop do the carb change over, but am waiting to see what you guys say before taking it back to them. |

OK. The symptoms you describe are classic 'too lean' conditions, confirmed by the much better running w/partial choke.
I am not familiar w/Blasts, but you need to look for air leaks (i.e. does the boot mount on a manifold? If so, there may be a leak between that manifold and the head.) Also check the timing, and confirm that it is correct. Is there proper fuel flow from the tank to the carb?
Check with the folks in the Thumper forum, and check the B.R.A.N. for Buellers in your area who may be able to help. The Thumper folks will know what jetting works, ect. |
