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 The previous version was outdated and no longer supported.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

I took my bike out last weekend and went riding for 15-20 min fine, then suddenly on a climb it started sputtering and crapped out. I was low on fuel, probably less then a quarter tank. I opened the petcock on the right side of the tank and was able to get it started after a few tries. Then I proceeded back to camp, but only able to crack the throttle just past idle before it would bog out....so I rode back 2miles or so like that. Once at camp I filled the gas and the issue didn't disappear. Any ideas?
 
Not sure why you had either petcock closed but keep both open so the fuel stays leveled in the tank. Maybe you have an air leak somewhere. Some folks have had rubber manifold caps crack and leak so worth checking you manifold nipple for sealing. Best to use a threaded screw in any case.
 
Yes, as Johnrg mentions, both petcocks should be open, all the time. They're only there to share fuel between both sides of the tank, without having to rely on it splashing over.

Did you have any other symptoms, like a flashing FI light?
 
Usually the petcock is open idk what happened there. No other issues. No Fi light. I will check the plug I guess...have 1500 miles. Oh the charcoal canister it burn a hole in it....from hitting the head pipe. Although, that had no effect to the motor running.
 
I'd inspect that manifold hose for cracks then that goes to the canister. if it idles well but worse when you turn the throttle, maybe the fuel pump, injector, filter. Check your tank vent/hose also in case it's kinked. Maybe check the battery as well.
 
years later, I'm having the same issue. I've checked and cleaned my injector, seems fine. I have a new fuel pump in there (less than a year old), I checked the pressure and it's 45 psi to the throttle body. I've popped my fuel tank cap off, just to be sure - no effect. Checked the airbox and throttle body and it's clean with no restrictions. Like the other rider, I went out for a ride and it was working perfectly - took a break and it fired right up, but the longer I ride, the worse the bogging gets - right off, it's not bad, but will pop, but 20 seconds later nothing much more than an idle.
 
You can have a fuel filter issue. The cheap one in the tank. George changed mine out and voila….power restored
