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 The previous version was outdated and no longer supported.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

125-200cc WR125 1999 Oil to Fuel Mix Ratio Question

Hi to all, I recently bought this bike. I downloaded the user manual from the website but could not find the one for my year of make 1999. The new model 2013 WR125 suggests 4% oil to fuel. The guy that I bought this bike told me he used to run it at around 1,2% oil to fuel. He told me that 1,5% oil to fuel will be too much.

I am afraid of destroying the engine with only 1,2% of oil to fuel. On the other hand the previous owner had this bike since 2001 and the bike hasnt even had a piston change yet. Since he is a friend of a friend of mine, he has no reason to lie to me as to this matter. As can be seen from the picture the bike was well looked after. Any feedback would be much appreciated.

With a good fully synthetic oil - running at 40:1 (or 2.5% oil to fuel) is what i would advise. I personally think 50:1 is a bit lean but it can be dependant on the type of riding your doing.
 
Initially I used 50:1 or (2% oil to fuel) and a lot of black oil was coming out of the exhaust until the spark plug died. When I replaced it, it was full of black oil. At the moment I am using (1,5% oil to fuel) or 50:0.75 and it still seems to be a lot if I judge from the black oil coming off from the back of the exhaust. I usually ride around trees in the mountain.
 
If its that bad then you have probably got a jetting problem. Idling around can tend to give that black spooge from the exhaust even at leaner ratios. If you are running at 50:1 and fouling plugs under reasonable riding conditions, then it is probably suffering from fuel fouling and not oil. Also, repacking your muffler, checking your reed valves and the blow by on the piston (seen as its never been replaced) might be worthwhile.
