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 The previous version was outdated and no longer supported.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

2008 TE450 running rough after maintenance

I did a big tear down for a few different reasons but during the maintenance I pulled the engine, suspension and pretty much everything electrical got disconnected. I shimmed the valves, and put everything back together. Bike was running well before. It has the P/U kit with 02 sensor installed and emissions stuff removed.
After putting everything back together the bike would not start with the fuel nob pulled out. I pushed that in and bike fired up, but immediately when to a high idle condition. The bike got hot quickly so I could not play too much. The idle will go to normal but it is hunting all over the place. I have had the low idle flame out problem but not high idle. I checked my connections and boots. I do not see anything yet. Has anyone else seen a similar problem? I have not found anything on search yet. Anybody with a bad 02 sensor has this issue?

Thanks for any help.
 
No I did not go that far. Another symptom I just found, is that when I rev the engine will sometimes stay that the rpm for a while. I.E. I got up to 4200 rpm and the bike stayed there after I had rolled off. Got to be electrical right? I looked that the throttle cables and they are fine. Probably does not matter but the bike has around 4k on it.
 
One more piece of info, I unplugged the 02(lambda) sensor this morning and ran the bike for a few minutes. The revs up and down were gone, it stayed at a consistent high idle. Going to put a resistor in this afternoon and see if that does the trick.
 
No, I'll probably tear down the intake to the engine and check everything, if the sensor trick does not fix it. I did not think about rechecking the valves. 99% sure I set them properly. Any reason to recheck?
 
Alright so I had two issues going on. One the lambda sensor was bad(Probably got something on it during rebuild). Two my throttle was off the idle stop(poor inspection when putting together). Time to go play with my new suspension, brap on :banana:

Thanks for the helpful thoughts OHR!
 
Good work Mate. Always great to get these matters resolved. You deserve 10 beers and a big ride
