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 The previous version was outdated and no longer supported.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

Help please, bike is not running very well :(

Hi Guys, I am a bit frustrated with a problem that I am having with my Husky.
I have a 2008 EFI TE450 And recently it has been playing up, its just come into summer here so I am not sure if the temp is something to do with it?
If I ride around at normal speeds the bike is fine, but if I accelerate through the gears hard at the end of the run the bike cuts out.
I can straight away start the bike up again and it will run fine until the next time I accelerate hard.
Can anyone shed some light onto this problem for me?
Thanks
Andy
 
I was first thinking it was a slow or siezed pump, as you say the weather is hot, but if the bike will start up straight away without letting the pump cool down, it might not be that.
I had similar symptoms as this on my 2010 450, and all it turned out to be was a very tiny amount of sludge in the injector gauze filter. It's an easy fix, and costs nothing, so worth a check anyway, as it only takes sludge about the size of 1/4 grain of rice to block this filter!

See my thread 'TE450 bogging and leaning out' in this section.
 
Thanks Tetley, yes I have been reading your thread regarding the sludge and the injector. I am in the process of stripping down my throttle body now so hopefully I might get lucky and that is the problem.
I also found a broken O ring where the body mounts up to the head, not sure if that might also be the cause of sucking in to much air?
Thanks
Andrew
 
Air leaks in the inlet will cause worse mixture problems at closed throttle, not wide open throttle due to the high vacuum present at closed throttle.
Another thing worth checking is all the wiring under the tank - chafes /rub throughs, broken wires, corroded connectors, and bad grounds. The ignition switch, relays and fuses aren't immune from dirt and corrosion.
 
If this happens when only on hot days and only after hard acceleration then I'm willing to bet your top end fuel setting is too low and leaning out.

Reason I say this is because it only happens when hot, so your hotter air mixed with fuel that burns sooner on a hot day will result in a lean mixture. The bike must be set up for either high altitude riding or mostly cold weather riding, and the top end is borderline too lean.

Can you hook your bike up to an iBeat? If so, I can tell you what the settings should be.
 
Hi guys, I ended up bitting the bullet and giving the bike to a tuners to get looked at they found two problems with the bike. One was the water temp sensor, apparently the sensors were a problem on these models. And the guys mentioned that the original fuel maps were a bit ordinary on my model so I got him to write me up a full custom fuel map for the bike.
Done my first track day with the bike yesterday and it ran perfectly all day :)
Thanks for your input guys.
