Buell Blast 1st gear

norub41 · #1 7th December 2009

Hi all, I have a 2003 Blast with 4000 miles. When I put in into first gear and let out the clutch the bike engages the trans and rolls about a foot or so then jumps like the clutch was pulled in and quickly released. It will also do this if I let off the throttle and roll it on while in first without touching the clutch. It almost feels like the belt jumped some teeth. The belt seems ok, the clutch cable has been replaced. I have taken the clutch apart to inspect it and all seems ok. The shift plate is ok. And the primary chain was adjusted properly as the clutch was also. Just wondering if anyone else had this problem before I take the cases apart to inspect the trans. Thanks for your help.

Does anyone know the outcome of this?

My blast is doing the exact same thing

My 2000 C did something similar, intermittently, and traced it back to grooves worn on the inside of the clutch basket.

Those are classic symptoms of of worn engagement dogs.

Unfortunately, a Blast does not have a trap door transmission.

My bike is a 2003 with only 3600 miles. its hard for me to believe that anything is worn out. but i just bought the bike and it was the previous owners first bike.

How expensive to replace the engagement dogs? or how hard to do yourself?

Here's what it looks like:

When the corners of the engagement dogs get worn like this, the transmission will jump out of gear (and generally back in) when you apply a load.

The parts aren't overly expensive, and in the older bikes it's not even a very big job to change them. But on a Blast or a Buell XB or a 2004-up Sportster it's a full motor tear-down.

That sounds like a pain. lol is it bad for the bike to continue riding and just take it easy in first gear. I do not feel the symptoms in any other gear. I just bought the bike as a commuter for work and back.

Well, it's only going to get worse. It's also putting pressure on the shift fork when it hops out, which isn't good for it.

Thanks, I guess i may take it somewhere to get fix or start tearing it apart myself

So, is this a trans, or motor issue?
