  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

TE 449 Engine won't return to idle

Im not sure if there is already a thread about this but it seems to be a common problem with these bikes. During a ride, when you have to shut the throttle off to negotiate a situation, the engine will hold the throttle slightly on which can make for some entertaining situations. I am used to it now but would rather it not be there. Just hoping someone has figured out the cure.
 
This old advice worked for me:

TPS Quick Reset
- Fully Warm Motorcycle
- Disconnect the battery for approx 2 minute, then hook it back up again.
- Turn the ignition key on.
- Turn the throttle to full stop and then back again.
- Turn the ignition key off, wait 5 seconds, and then turn it back on again.
- Start the bike without touching the throttle.

TE511 Air Bypass EFI Adjustment
- This is the big brass screw high up on the side of the EFI body
- 2 ¼ turns out for a TE511 (+/- 1/8th of a turn) should put the minimum air bypass back in range.
- It is the only screw on the throttle body that should, or can, be touched without major drama.
- If the screw is too far out it will push you into a corner like having the throttle open a bit.


I will be surprised if these 2 procedures do not help. Do the TPS reset twice to be sure.

Also, just a thought but take the EFI cable cover off the side of the EFI main body and check if all the cable adjusting screws are tight and that the cables wind around the cam correctly through its full range of movement. While you are there you might as well check for the correct cable backlash/freeplay. There is a section in the owners manual that touches on this.

I had same two years ago. Too high idle rpms. Turn big brass screw on throttle body.
 
Try the simple stuff first and work from there. The procedures listed by Gillies are quick simple and free. I wouldn't go removing the butterfly yet until you've exhausted the other possibilities.
 
Thanks for the info guys, ill let you know how I go, great bike by the way, its a crying shame it didn't see a few more years of development.
