  • 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 The previous version was outdated and no longer supported.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 TE510 PROBLEMS

The other day I was riding my bike to work and after 10 miles it started missing really bad when I would open it up. I had all I could do to limp it to work the last 10 miles. Later on when I tried to start it it would not idle for long or take any throttle with out dying. When I would crank it with the throttle open it would only run for a few seconds while missing and coughing. Now it will not run.
I replaced the fuel pump about 15 hours ago and when I first turn on the key you can hear the pump energizing so I'm assuming ..... its not the pump. I am stumped as to why it was running perfectly fine one second and bad the next. I checked for loose wires but I really didn't see any. I always run premium gas without ethanol so I assume that is also ok.The fuel pump I replaced was bigger than the stock one so I had to rig it up to fit and I'm thinking maybe something loosened up due to vibration seeing as how I had to wedge it in.
Any thoughts ,suggestions, insights, te tips ....??? Help, my swedish girlfriend is acting up****************************************:confused:
 
why did you replace fuel pump? I would dis assemble and trace each and every step you took, while looking for other associated wiring possibilities along the way...it's a fuel issue or a short.
 
My 08' TE510 did something similar a couple years ago. Bike ran fine,no hiccups. Changed the oil, decided I would prime the engine oil by slowly kicking the motor over with the decompression lever pulled in, key off. Turned key on and tried to start. Would not even attempt to fire up unless i was trying to give it full throttle. Battery wore down to the point that I was kicking furiously. Finally fired up and only would stay running up and over 6000 rpm. Took it around the block a few times feathering the clutch to keep it running to try to recharge the battery. Took the bike to Dan at Motoxotica. Took everything to get the bike running up to 80 something degrees so be could hook it up to the Ibeat. Somehow the TPS got thrown out of whack. Nothing loosened up inside the throttle body. After he adjusted with Ibeat, it has been fine. It still stumps me to why in the world this happened.

Did you pull the fuel pump assembly and look at it?

yea I'd take a look- the pump could be running fine, but something could have came loose. Such as one of your hoses is leaking at the connection and is loosing fuel pressure. It just makes sense to look where the problem has been first. good luck

yea that's strange- only thing I can think of is that the hard stop closed throttle adjustment screw and lock nut came loose or there was no locking nut and it slowly migrated out of adjustment.
 
Very weird indeed. I had already secured the fuel pump. All the connections at the throttle cable were tight. All Dan had to do was adjust with ibeat and it was fine. I do want to pull out the fuel pump again one of these days and do a double over on it and make sure everything is kosher.
 
So learned a valuable lesson this weekend with my bike. I too changed the fuel pump and suspected I might need to replace the wiring loom as the bike would intermittently just die (like it was suffering from fuel starvation), and starting it from cold was a PITA.

Turns out the spark plug was dodgy. So it was not so much a fuel starvation problem as it was a fuel ignition issue. I've heard that when spark plugs die they can play up intermittently at first for a while.

You might just want to check that you're getting decent spark. In fact, plugs are so cheap that you may as well just replace the plug anyway if you haven't changed it in a while. I would STRONGLY recommend going for an Iridium plug as they are not much more expensive, but have a much more reliable and cleaner spark and are less prone to carbon build-up.

Good luck sorting the problem out.
 
That's not a bad thought. I have 2000 miles on mine now. I think I might be getting another part.
 
Good News. The problem was simple to resolve. The hose clamp on the fuel line to the fuel pump had loosened up and the pump was sucking air. I replaced the hose clamp with a beefier hydraulic hose clamp, tightened it up and she fired right up. Whew!!
