• 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 The previous version was outdated and no longer supported.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!

JD tuner not working on TE450

Hey crew. Looking for some help. I have an 08 TE450 powered up and Arrow exhaust with a JD tuner on it. Bike had been running great and love the JD on it as it smoothed it out. However, I had a small off trail riding and the bike would not start (been running single track). Pump primmed and bike turned over, just would not fire. I guess I flooded it as fuel was leaking out the exhaust header??? We were out in the sticks, but had tools and took it all apart looking for loose wires and what have you. Finally after an hour of playing and no success, unpluged the JD and went to stock and the bike fired up! Got home no problem.

While at home, took the tank back off and plugged the JD back in. Again flooded the header and no start- wanted to, but was flooding the head. So back to stock and it fired up and ran fine.

I am guessing when I crashed (very minor tip over in the bushes at low speed) I may have hit the controller? but I cannot check the settings as the bike has to be running to do this correct? Seems the bike is getting way to much fuel and flooding it out?

Anyone heard of this? I have not called JD yet as this just happened. Any help much appreciated.

Thanks,

Matto
 
The only way there is gas flowing into the intake manifold and then into the head is that the injector is stuck on full open, either the TPS is saying "full throttle" or something else is connected/grounded in the Tuner that is opening the injector fully and the pump priming is squirted fuel past an errantly open injector into the head..
 
check your wires are not squashed, I trapped some of the wires on my JD between the seat and the frame causing the wires to break within the insulating plastic. The bike would not start at all until I repaired the wires.
 
What freaky says sounds logical. The tuner itself is pretty robust and it would take a pretty big impact to damage it. Where did you have it mounted? Cam.
 
I had a similar experience with the JD tuner. I solved my issue by pulling the ground wire off from under the rectifier and steel wooling the the frame to create a better ground. No issues since.
 
Thank you all for the replys. I will remove it tomorrow and see if there are any problems with the wires first and check the ground also. I had it mounted up on the triple tree near the dash. It did not get hit when I fell as far as I know. It was a light fall off a single track into some bushes.

Only thing I wish it that you could check the settings without the bike running to make sure everything was set correctly. Will report back what I find.

Thanks again!
