Just got a new brain.

My News Years day ride was cut short. It just stopped running. Had to trailer the LT to my local dealer. They replaced the main computer (to the tune of $1600, under extended warranty, thank you God).

Anyway... Just rode it for the 1st time this Sunday. My friends (on Harley's) said they smelled gas at the red lights. And it got an abismal 34 MPG through 350 miles.

I'm going to call the dealer and take it back in this week, if need be.

Any tricks to make it correct itself?? Like disconnect the battery and click my heels together 3 times? Or twist the throttle 4 times with the key in the on position? Or... just take it back to the dealer and let them fix it!

Thanks and safe riding,

Paul - Houston

Re: Just got a new brain.

Hey, Chann - couldn't he just pull the Motronic fuse (bottom fuse in the fuse box nearest the brake side of the bike) and leave it out for 15-20 minutes; reinsert it and then do the TPS dance to see if it helps the situation. Least that's what I do on ole Toad - a '99 model year. Not sure where that fuse is on newer model year bikes.

Re: Just got a new brain.

Check to be sure the QD's are seated properly and not leaking
Not that mine have ever leaked

QD's ??

This one's a 2003 model, BTW.

I disconnected the battery and tried the procedure. Seems a lot better now. I did not get a chance to ride yet, but it did not smell "gassy" when I started it. I'll take it for a good ride and check milage on Saturday.

Thanks everyone!

Thumbs up Re: Just got a new brain.

Ahhh! QD's... quick disconnects. Yeah, just replace both of them 3Q08. They are fine.

Thanks again!
