Just picked up a 2009 Road King Classic. Miles are low (12000) Had to do a lot of cleanup so it's looking pretty good. Bike is supposed to have a tune, has slip ons and hi flo a/c. In a low gear roll on to WOT the bike stumbles or quits pulling. Soon as I let off and shift to second back to WOT all is good. Any thoughts?

Thanks

 

Crap tune would be where I would think first. See if it does the same thing in second when you wind that all the way out.

You can go to a dealer and they can tell you if it has a Harley tune, or a Harley download by hooking it up to the Digital Technician in the shop, and... if it has some other kind of tune, they SHOULD be at least able to tell you that there IS a tune inside.

If they come back and tell you that the ECM is broken... tell them to STOP right there and take the bike home. It most likely is a TTS tune, if thats what they say. If it runs OK, it is NOT the ECM, my friend.

Post some pics when you get a chance. Some of like used bikes very much.

BTW, does it in low gear only.

 

Are you hitting the rev limiter?

 

No, it does it almost immediately.
