  • 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 The previous version was outdated and no longer supported.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 only starts & runs past 50% throttle, very poorly

TE510 died on me today up a hill climb, tried to restart it and it wouldn't go. Tried bump starting it and not so much as a hiccup until I opened the throttle way open past 50%, then it would run extremely poorly, only combusting once in a while, the more the throttle opened the better it started to run but it was still very sketchy

I only had basic tools, managed to check if the fuel pump was squirting a good amount of fuel and it was. Couldn't immediately see any issues with dislodged plugs or anything but I didn't have a lot of daylight so I just left it as it and had to ride the bike out with the throttle pretty much wide open in 1st gear using the clutch, thought I was going to blow the engine but I didn't have much choice

I had to go back across a river crossing to get out, soon as I hit the water the bike died. So it could very well be a short somewhere. It did eventually start again once it dried out somewhat and I found another hill to bump start on

I havn't booked it up to iBeat yet to check if its reported anything. Any ideas of what to check?
 
Check the intake boot for cracks, sometimes its hard to see that its damaged, use a small board the kinda pry the throttle body back from the head and looks for cracks.

Ok, lets look at basic's, plug out and does it spark ok on turn over = no then the ignition system or plug is the fault. If its not that then next over to fuel, turn the engine over for 15 secs and remove plug, is there fuel on the plug = no then the FI is at fault.
 
Checked for spark and there's plenty of it. Chopped some of the plug wire off anyway as it was a bit suspect, still no go
Checked iBeat and no logged faults, TPS working, all sensors working
Removed tank and went to remove throttle body, the forward boot clamp felt quite loose. It appears the throttle body may have popped out of its place. I checked it and its a little bit dirty on the engine side but really not much. Removed the carb boot from the engine anyway and couldn't see or feel any dust in there, only a tiny bit in the boot itself. Reassembled and it fired up straight away

Bit of a bummer, if I saw that on the trail I could have fixed it there and then. I was in a bit of a rush due to fading daylight. Oh well least the engine appears to be fine, still plenty of resistance in the kick starter
