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 The previous version was outdated and no longer supported.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

TE/TC 2015 te300 jetting recommendations

Picked up a new te300 and bought a jd jet kit. The new bike came with a 172 main and jd have me a 165. I'm a bit nervous with such a big drop. Any experience here? Thanks.image.jpg image.jpg
 
The stock jetting on my bike was way too rich. According to the table in the manual I was supposed to run a 172 main, 35 pilot and the N8R G needle. I ended up using a 170 main, 35 pilot and the N8R H needle in the second clip. I'm still a little rich and I think I'm gonna try something a little leaner. image.jpg
 
A lot has to do with your mix ratio. I leaned my 250 quite a bit but still run a little rich because I run 50:1 with motorex. You can call or email JD and ask what ratio they made the jet kit for.
 
I would also check the float height mine was way high out of the box I was getting less than 15 miles to the gallon and if I tipped my bike like 15 deg to the side fuel would pour out of the overflow tube.
wow kind of big changes from 14 to 15 interesting.
my 14 bold print box is as follows ASO 2, IJ 35, NDL N4D J, POS 4, MJ 168.

that MJ size really is strange, from OEM 168 to OEM 172 in the same temp/altitude box, did they find more airflow for 2015, or does that different needle make that much of a change???

by the way my settings are set at the next box up from the bold which again is totally different than the 2015 box. we ride mostly in the spec box above the OEM bold standard box, avg temp 65 alt 3k

But Im actually even leaner on the main using an M162 per JD spec that I have with my older JDK014 kit . Next week Im going back into the carb to try and get the bike to come off the bottom very smooth and clean like all the Beta300 Ive seen and ridden in the past year, my benchmark for what I want from the Husky/KTM 300 motor is Beta like of idle clean electric power.
 
Tried out jd jetting red needle 3 rd clip, 38 pilot, 168 main air screw 1.25 out.I also adjusted my float height so float was approx 1-2mm lower. I can lean my bike over 45deg without fuel leaking. I am at 500-1000 foot elevation. Bike runs much better. Still loads up a little on slow up hill trails. Cleans out easy though. Going to try jd blue needle in 4th clip next ride. The bike lugs like I can't believe!
 
The float level can have a real effect on gas mileage. Many don't notice but their bike will loose fuel constantly out the overflow hoses in rough terrain. My favorite setting method is to gently blow air (by mouth) though the fuel inlet then it is easy to tell at what float height the air flow is stopped by the float needle. Cam.
 
I also start most of my rides from around sea level. Anything smaller than a 172 main on these new 2015 bikes will be super lean on top. Anything larger than a 35 pilot and the bike will load up in the technical stuff. I tried the old KTM 300 go-to jetting of 38 pilot 168 main and got the same results as you did. I run a Suzuki NECJ needle 3rd clip in my bike. It should be pretty similar to the JD red needle. After the bike breaks in a bit, the jetting will be much less finicky with temperature and elevation changes.
 
I use the jd specs. Seem to be close, if not a tad rich. I had a 158 Mj in it last fall and it was still pretty fat above 8k. Jd recomends a 152 at that elevation i believe. Im riding 4k feet tomorrow and will use the 162 main, 38 pilot, and bulue in the number 2 spot.

What bike is this jetting for? A WR300 at 4K feet? I'm pretty sure a 2015 TE300 at 500 feet would seize with a 158 main.
 
Fact is if you jet exactly like the OEM manual shows you will always be safe, the factory is not going to risk having buyers lean seize and get hurt as well as having engine damage issues to deal with. And for as many bikes I have used JD jetting that also goes along with JD jetting as well.

The only really big thing that's strange to me is that 2014 TE300 and 2015 TE300 charts are so different, the 15 is a couple mains bigger in all the boxes! Did they find more airflow??
We are talking specifically about the TE300 White Husky that's it.

not sure where you got "500 feet" from. I was riding summertime temps (65 to 90 degrees Fahrenheit) at 8000 feet plus and it was rich. Would load up fairly bad at times and had so much drool off the silencer it was dripping on the swingarm. With a 158 main. I'm jetting a 14 te300.
 
Here is the info JD sent me for the TE300.

I spoke with JD about my problem loading up just off idle. They told me to go back to stock 35 pilot, a 162 main , and keep red needle 3rd clip. Took short ride today and feels a lot better. Need to take a good ride to make a determination though.
 
The difference between the 14' and 15' is huge for jetting. 3 or more sizes up on the main, and one smaller on the pilot is the difference from 14' to 15'. I got 500 feet from the original post. That is who I was trying to help with jetting.
 
I'm curious to what changed between my 14 and his 15. The OP asked about the large difference between factory spec and his JD kit. I run the kit, so i shared my experience with it. Like I said, 158 was even fat at elevation. Yes, you are correct, at 500 feet I'd have a 165 or 168 even depending on temps. Keep in mind JD does spec a 38 pilot. Not a huge factor but still could play a small role in a smaller main. I could be wrong though. Would a different slide change the jetting on the main? Maybe the 15s have a different slide?
 
The carburettor setting has been revised for MY15 and guarantees smoother power delivery. The TE 300 engine features a .......

This is from the 2015 TE300 factory advert. I am interested to check all the specs of the 15 as opposed to my 14 after seeing these large jetting differences. I have been chasing my personal fave setup and so far I have M162 P35, AS2, forget what Keihin needle and pos with a FMF gnarley and OEM stock muffler, long smooth power is what I want and shes getting closer and closer. By the advert it sounds like found an even more smooth even power setting for the TE300
 
Wondering if there is any new jetting info for the 15 300's. Finally got this beast out for a few laps around the neighborhood and it seems fat on the main for sure. I live in the Chicago area which is 300ft. you would think the 38 pilot and 172 main would be on the lean side, but the temps and elevation call for a 38 pilot and 178 main. given that its having trouble clearing its throat during 3 gear roll ons I am hesitate to jump that high on the main. Any thought or suggestions? I am also curious about the big differences in jetting from previous years. Seems there is no concrete reasons why the big jump richer?
 
I'm in the Seattle area so about same elevation. Jd red needle mid clip. 35 pilot and 165 main. Still feels a bit fat but cleans up easy and has no bog of throttle.
