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 The previous version was outdated and no longer supported.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

Hi guys I am having trouble kick starting wr250 2013, (the Italian made model) It backfires and kicks back and won’t start. I can run start it and it runs good but doesn’t like idling. It has a mikuni carbi and I have put a new kit in it to try and see if that will fix it but no joy! I have put electrical grease in any plug or spade I could find. When I take the spark plug out after kicking it it’s always wet, perhaps too wet and I have had the spark plug out when kicking it and it appears to be sparking fine. Any ideas would be much appreciated
 
Check every detail in your carb before moving on. Float level correct, pilot circuit jet AND passage ways cleared, all vent lines unobstructed, fuel needle valve seat and o ring not leaking, reed petals all in good shape without any warping or damage. You will probably find jetting specs in the jetting chat sub forum here. You didn't say what kind of jetting kit you installed, but you need to make sure that you have the correct sizes of everything, including the starter jet.
Get a good NGK waterproof spark plug cap to install. Check all grounds related to ignition.
 
Thanks dirtdame for your help. I have cleaned out carb about 4 times including all passage ways and jets, I change float height a couple of time as I had fuel dripping out overflow pipe but that has now stopped. The carb kit I put in wasn’t a jetting kit just new gaskets, orings, fuel neddle and seat etc. I have inspected reeds and they look in good condition. The only ground I have checked are the ones attached to regulator are there any others?
Thanks again.
 
If it has compression and air+gas in a decent proportion the only part left is spark, maybe there is none/weak or at the wrong timing. Have you tried pushing it down a hill so you get a little more revolutions ? My WR300 was a bit** to start sometimes when the jetting was off and pushing it down a hill was way easier than wrecking my right leg kicking it :D
 
the 2013 Mikuni has some pretty smaller vents for the pilot jet
consider cleaning the carb with a sonic cleaner, like a jewelry cleaner only larger
 
Hey I found the problem eventually, it was the magnets in the flywheel had come loose and slid round a bit and put the timing out slightly. I’m having trouble finding a new flywheel anywhere! Does anyone know where I may find one? If not how can I set the timing ? Thanks guys and girls.

get an owners manual or a service manual, they will have the instructions and timing settings
