  • 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 The previous version was outdated and no longer supported.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 2012 WR 144 OEM Mikuni vs. Keihin pwk

Thanks for the info guys.

The oem Mukini seems to be working decent, but I am getting fuel spill when leaning on the stand (alot of fuel), and my freind says also a little dripping riding over rocks and rough stuff. So I guess I have to check the float level and maybe lower it a little.

Would a high float level cuase any low speed sputtering untill I clean it up with some revs?

A high float will also cause poor gas mileage.
 
I screwed with jetting almost every ride with the mikuni, put on the motosportz PWK and havent touched it in 2 years. That said, I gave my stock mikuni to my buddy on his yz125, and he loves it. Go figure.
 
Yeah my float level was way off....I don't think it was ever set properly at the dealer. I had to lower it, and now it only drips if I lean it past the stand. Thanks guys.

Thanks. And will the carb have TMXX stamped on the side? Becuase like I mentioned my 2012 has TMX stamped on the right side of the carb.

TMXX was just a name we have given to the newer carb to help differiate them. The older TMX has the rectangular slide. The newer TMXX has the rounded-shape slide.
 
I have done A LOT of carb testing on my 11 wr300. And I now like the tmxx better than the pwk. If you want more snap from the Mik, take a small grinder or file the the small half hole on the reed side of the slide. I made mine wider, not deeper and it made it very snappy.

Can you post pictures of this? Did this mod help off idle response?

There is always one guy who is different All my Husky be it my 125 or my 165 or my 250 or my 300 run the stock carb
Both the 2006CR 125 and the 2008 CR 165 run the same carb same setting same everything.Runs perfect every where from sea level to 8,000 feet.Watch my last 2 videos and tell me the bike does not sound like it is running great.Then there is my 2006 WR250 also stock carb My 2010 CR 300 which was the motocross action bike
which pro circut but the big motor and keihin in I purchased that bike but now with a stock motor still cr electronics but it had the keihin carb.The bike ran bad even afte I purchased a JD carb kit I still could not get it to run correct.So I took the 2006 carb off the WR 250 installed it on the 300 and it now runs perfect.Then I had Walt find me a old 2006 mikuni which I set up like the now 300 carb and bingo the 250 runs great.As for the keihin I traded it off for another stock carb.
So I am the odd one out my bikes run fine to me with the stock carb.I also run race gas and some where around 35 to 1
 
I have the stock mikuni tmxx on my '10 wr144 and it runs very well with no bogs or blubbering. I am just fine tuning the jetting now to see if I can make it even better. All it took for me was patience and learning how much each circuit over-laps another,plug readings ,and listening to the bike (it will tell you what it wants if you listen). I got base-line settings from the jetting threads in this forum and adjusted from there.Once I am satisfied that I can't improve the jetting any further, I will post my settings in the jetting thread and hopefully help out others like they helped me. That's what's great about this forum:applause:!
 
I am on the fence abut the PWK it did help my wr 125 down low but missed the revvy feel of Mikuni .
Has anyone got the older TMX to run well on a wr 125 ?? I dont think the same rm needle trick applies . I guess the divider plate is the go .
 
can someone recommend a good source to buy a brand new Mukini for a wr125? I want to keep the stock one and send another one to RB.

There should be lots of them laying around from riders who switched to Keihin. Have you tried the wanted section here on CH?
 
I've got a basically new tmxx I'd sell for $100. Includes stock needle, RM needle and whatever jets I've got left over.
The pwk36 is magic on my 125, so the tmxx has been sitting around collecting dust.
 
mine works really well but has the cr ignition, timing advanced 3 degrees, diy divider plate and slide reshaped and the jettting is 27.5 pilot and 370 main.i will be fitting a bigger main and lowering needle to try and clear up some loading on long slow sections (2 nd gear just off idle).
