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 The previous version was outdated and no longer supported.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

More Carb news, TMxx info this time

OK, I just contacted my super secret inside guy at JD (also my new suspension guy) and he said they have the kits done and built and ready to go but not on the web site yet. They are $98.95 which is a little more than the other kits because it includes a nozzle that was necessary to make them run right.

If anyone wants one of these kits Email me and I'll get it coming to you ASAP.

I will be picking one up Friday and testing it shortly. thanks.

does the nozzle = emulsion tube?

I may be talking out my ass, but dealing with my wetbike, thats what the dudes over at wetbike.net call it.

The emulsion tube is part of the needle jet. They seem to like to call the needle jet an emulsion tube more often on fourstroke machines, than on two stroke bikes. If you look at most OEM parts lists for two stroke motorcycles, the part is called the needle jet. The top part is called an air dam, by the way.

As usual, I look forward to your report! Is the jd jet kit for a certain displacement or does it cover all the 2-stroke huskys witha tmxx?
 
The needle jet he sent me is a larger diameter to work with some needles he already makes. I ended up with a 5.5 slide also.

The jetting on the 125 and 250 are almost identical and the 300 can't be far off. I would think a few jets ether way would get it done.
 
This is going to be interesting. First, the APT test, the Lectron test (hopefully today), and now JD making a kit. Whats next, a new PWK, or DI?
 
Jake just stopped by and grabbed pistons, rings, pipes (KX125 and Doma both for husky) and the TMxx JD kit. He has two TMxx's so he will JD one and swap it out with his slightly rejetted stock carb. His bike is a pretty stock 09 CR125 that is fresh and runs well. I also encouraged him to try my KX125 and Doma pipes I has laying around here. This should be interesting.
 
So I just updated the original post to show...

APT - Rules
Lectron - Rules
TMxx with kit - very good
Stock TMX - works fine on my CR

I just got a "from the field" report mid test from Jake (thats how the Motosportz team rolls :>) He had his stock TMxx on hos 09 CR125 dialed as much was he cared to. Seems to run good but he is running the stock pipe that I hate. :) Anyway reports were very good. Said it was much better but lean at first. He richened the needle and said it was real good bottom to top.


So, the JD jetting TMxx carb kit seems like a very nice alternative as well. Look forward to Jakes report.

I'm sure this will get viewed as my transparent attempt to crash Lectron sales :lol: (carb fiasco joke)
 
Maybe. With my short exposure to the APT and Lectron they both offer "more" to me. The throttle response and roll on power and overall smoothness both the metering rod carbs have me convinced so far that they are a step ahead of the game. Might be some extended mileage with them too. Need more time on them. Spoke to Jake again, he is pretty please with the TMxx and JD.
 
Kelly was supposed to be there for this little test session but he had family duties... So he had a different kind of fun.

He is much better at reporting this type of stuff but I will do what I can.

I had the TMXX dialed as good as I could with the RM needle and #5 slide. It ran good enough but had a bad stumble after down hills and would take a bit to clean out.

I have a spare TMXX so I set up the JD kit in the spare and swapped them after a quick warm up. The plug check after the warm up was showing a bit on the rich side.

I had a little 1 mile single track at a friends house that was perfect for testing, I knew right away if there was an improvement.

The JD settings in the instructions were for a 250/300 so after talking to Dave at JD I started with one clip richer on the needle. I noticed immediately it was crisper and ran better but a bit too lean on the bottom and it had a pretty good bog. So I dropped the clip 1 more and it ripped but still had a small bog if I got stupid with the throttle so I turned in the air screw a half turn and rode it. It runs much much better, feels like it comes on the pipe about 2krpm sooner and is really fun to ride. The bottom might still be a bit lean, I will fine tune that a bit more. I didn't do any long top end runs but the top end feels great, pulls long and hard.

Plug check after the ride was perfect, a nice cocoa brown color. Makes me a happy camper.

I will post some before and after videos when they upload, until then here is a mid ride video.

Here are the settings I ended up with at the end of the ride.

420 main
32.5 pilot
Jd red needle 4th clip down
#4 slide
air screw 1 turn out

I rode the APT and hope to try out the Lectron soon, the APT was electric smooth almost like fuel injection. I really hope the current setup with the JD kit will be consistent with temperature and elevation changes. If it doesn't I may have to pay the piper for a Lectron.

Later,
 
So, Jake, it sounds like overall the JD kit is a sufficient improvement over stock, to the extent that it's worth the $90 (or whatever)? I am very interested in this. How did it impact idle/starting, which I think is a weak point of the TMXX?

I think that the main "benefit" of the JD kit is just cost; it's way cheaper than the APT/Lectron!

It is a huge improvement over stock, and a good improvement over the RM needle and #5 slide combo I have ran for the last 2 years. I just hope it is a bit more consistent with this setup. Idle is a bit lower and it will die after 10 seconds or so. I am okay with that on a two stroke, the previous setup I had the idle cranked way up.

Here is the first run with the RM needle setup, it is crackly and rich.

More of that run after clearing trail trash...

Here is the first test with the JD kit...

More of the same after clearing more trash big lean bog trying to climb this hill...

And one more after raising the needle much better but still need to work on the low end a touch.

This one was after gaining 500 feet in elevation and dropping about 5 degrees, the bottom that was already lean was just on the edge of bogging. I turned in the air screw 1/4 turn and that is where I left it.
