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 The previous version was outdated and no longer supported.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

Sorting out 310R hot start struggle

Hi to all Cafe Husky users,
I'm having some problems with the hot starts of the 310R; in the beginning of this year I was lucky enough to find a oem Husky GET ECU for a TC250 2013 (red cdi) and to have a shop load a map for the 310.
Bike runs good and starts fine cold on the very first kick but when I need to restart (hot engine) there is no chance of it firing with the kicker and the e-start takes some rivolution to start (too many against what I was used to the with the OEM CDI).
To give the complete picture before the GET cdi I had the OEM keihin CDI running on map3 and the power commander and the hot start was not a issue, I could immediatly restart with one or two kicks, e-start was also quite immediate. I've already checked valve clearences ad set the left that operates on the decompressor a little below 0,20, TPS is set at 650 mV and idle is above 2200 rpm (for e-start I also have a 245 CCA battery and it spins fast).
With the ECU they gave me the VT1 programmer that allows you to edit in a small range the % of fuel, set tps value and adjust the advance.
What parameter you think I can change with the VT1 to improve the hot start or what other things I should trace to be able again to hot start it with the kickstart (obviously without going back to stock because the power gain is notable)
 
The timing curve probably needs to be difference for the initial restart, but that is strange. Is there any chance your battery is getting weak by coincidence or a ground issue? Wiring is just as critical when hot.
The other thing… not familiar with the newer 310, but the older style had a compression release/hot start lever.
 
I just remember there is a similar issue with the JD racing CDI on the two strokes for the FBF maps. One you literally wouldn’t hardly be able to start it hot or cold due to the ignition timing. The same principles apply for ignition.
