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 The previous version was outdated and no longer supported.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

310R popping & hard start

Here we go again. After first few rides on the season, I see that the problems persist, but are worse: After warm up to operating temp, the bike will not idle more than a few seconds. Tight single track riding is not fun, as the issues are worse in low rpm / low throttle running. It wants to die often when the throttle is closed. Runs great with throttle opened more than 1/8.

Have checked TPS, set to .68v. Resistance across TPS is 700 ohm closed, 1400 ohm at open.
Checked resistance across injector connection pins: 9 ohm. Do not know correct resistance & do not fine the number in WSM.
Checked coil resistance: About 0.1 ohm across pins. My meter scale does not go down to deci ohm. Reads to spec - 5700 ohm on secondary. Do these coils tend to go bad when hot?
I have read other threads re. similar problems & symptoms which were fixed with new coil or injector.
My first choice to replace would be injector. I'm open to suggestions & info. Thanks

I'll give a few quick answers: TPS at full throttle should be in the 3900ohm neighborhood (so look hard here; also make sure you measure the correct 2 wires), 700 ohms is good for closed throttle. Injector resistance is 10 or 11 ohms... I think you're okay with 9ohms. Coil primary resistance sounds fine; also there are not many reports of the stick coil failing. Speaking of coils, the pick-up coil can go intermittent on our bikes and are not available separate from the stator (sometimes you can find them aftermarket though)- and they do cause a lot of weird voodoo.

hot idle should be 2000+ rpms. Adjust as necessary

This thread is kinda old now, and you never really answered any questions about the history or solutions.... why don't you start a new thread with a description of your current problems.

good luck.
