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 The previous version was outdated and no longer supported.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

Bike idling too high after small crash

B Class
I took an easy spill yesterday and after I started the bike again it was idling between 4k-5k rpm. I tried getting it down to normal idling conditions by adjusting the idle screw but it didn't help. I then realized that the hot/cold start lever by the clutch was extremely tight (too tight to even get it engaged). Is it possible that somehow the cable got stucked? If so, any ideas how I can confirm this and get it fixed?

Thanks in advance.
 
What bike do you have? EDIT::: I SEE it IN your SIG NOW- Just ignore the carb refferances

The lever by the clutch-

should be a manual decompression on most. This lever will NOT cause a high idle. However, if it is not working properly and is say half pulled and sticking you could cause wear to your valvetrain.... inspect this further- follow the cable from the lever to the head on the right side where it attatches for damage or cause...

But if yours is carbed someone could have modified or added a hotstart lever- which opens up an air circuit in your carb- this could cause a high idle. simply follow the cable to where it goes- to the Head or to the Carb​

Things to check with your high idle at 4-5000 rpms:
I would check the throttle cable and ensure it is not sticking partially open- if you have handguards they could have gotten tweeked and are simply rubbing on the grips. Throttle should smoothly open and snap back till it hits the throttle stop.
Check your intake manifolds (air box to throttle body/ or carb) and Throttle body/ or carb to head) If you have a leak or tear in the manifold it will add air- for carbs it will cause it to lean out and rpms will rise- with efi more air= more fuel= more rpms... First Inspect the manifolds by looking for obvious things- then Start the bike and then spray WD40 around the boots and see if the idle changes- if it does you have an intake leak. Inspect further- Loosen and reattach manifolds and ensure they are not damaged... Also ensure the Crankcase breather hose is attatched properly- (and if you have the Charcoal Canister installed yet- the connection to the throttle body may have come loose) If you took off the charcoal canister- you plugged the inlet nipple to your throttle body most likely with a rubber vacume plug (or your dealer did) it may have came off and is causing the leak- take this inlet nipple off by unscrewing it (standard screwdriver -if I remember right) and match up the right bolt size and thread and replace with a bolt- If I remember right its an 8mm- I cut a bolt to the same thread length as the brass inlet nipple and replaced that instead- NO more ever worrying about that...

:busted:also make sure if you have EFI that you don't have your Air bypass knob on the left side of the throttle boddy pulled out- cause that could simply be it... (I am sure you wouldn't have overlooked this but obvious stuff sometimes gets us all)
:thumbsup:
 
It's your hot start lever. It's stuck open, which is like having the throttle cracked. Figure out what's wrong with it and you'll idle will go down.

The cable is easy to pull from it's ends, so start there.
 
Thanks for the feedback guys. I'll start by looking at the hot start cable as it is suspicious that I can't pull it back (engage it) and it's probably a quick thing to diagnose. If that isn't the culprit I will follow the other suggestions and hopefully something checks positive so that I can fix it prior to the weekend (signed up for an Enduro on Sunday).
