  • 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 The previous version was outdated and no longer supported.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 My New 2013 WR144 with Lectron

I am super stoked! Just picked up a leftover '13 wr144 with a dealer installed lectron.

What are the important hop ups?

Tips on tuning lectron? (Running really rich)

How should I break the motor in?

Thanks this forum was pivotal in my decision, almost went with a 310 but came back to the 144 with the recommendations of this board




 
Get the suspension set up for your riding and person

pretty much done deal after that.

if you are interesting in pimping up the bling factor then there is a whole list to follow.

are you familiar with the lectron? where do you feel its running rich? is the float level riding inside the markings on your bowl?

I am not familiar with it. But Its smoking alot! it could be because its new??

I have no idea which is idle, metering etc.. I have no instruction and the dealer wasn't very helpful
 
Go to the lectron website and download the tuning guide. Has all you need to know to set it up to the best tune.
 
Love the fact the reed block is on the cases and not the cylinder!
Keeping my eye out for 125/44 in uk
 
yes very easy to tune. its smoking, but does it run well? i would not base my carb tuning on how it smokes. check out the lectron site and it you have questions we can help. you should be somewhere around 40:1, maybe 32:1 if raced. when jetted correctly i have had no smoke or spooge problems with 40:1.
 
Thanks, I will try to figure it out tomorrow.
It runs fine but I have excessive smoke and Spooge at high rpm?

When the idle screw is 1 1/2 per motosportz thread it idles super high.

I'm sure I just new to get it adjusted properly.
 
Basically you adjust the Lectron from idle all the way through 7/8 throttle by lengthening=leaner or shortening=richer the needle. Once you have that done you adjust the wide open/last 1/8 by turning the power-jet clockwise=leaner or counterclockwise=richer. Set the idle where you want it and you're done... altitude has very little effect on it. If I'm going to ride in the sand all day especially on a cold day with good air I will turn the power-jet screw out 1/4 turn to make it a tad rich so it's easier on the engine when you're pinning it all day.

The lectron webside will explain how to turn the needle and then re-index it so the the flat side is facing the engine.

I don't know, lectron was installed by dealer when I bought it.

I can see the carb doing it unless it's injecting way to much feul at high rpm wich is the only time its spits the grey

Could it be un burned fuel??

Pretty much spot on. All I can add is don't forget to play with the external powerjet as it has more overlap than you might think on some bikes.
 
the hole for the powerjet is halfway up the carb body, so i thought the powerjet is operational over 50 percent throttle.

Thats the choke hole the powerjet hangs down into the top 3rd of the opening.
Or am i again confuddled.

it depends on which nozzle is installed. mine hangs down right at halfway. i have seen some that the nozzle only hangs down a third. im guessing this is how you tune when you want to powerjet to work. my manual states the purpose of the powerjet is to"fine tune mid to high throttle positions"

edit: i see lectron offers two different nozzle lengths. one must be half like mine and the other upper third like you have. i need to try the shorter one
 
Do you guys have a recomendation for what plug and gap to use for the 144 with lectron? Even after leaning out the PJ I still seem to have to much unburned fuel

Thanks
 
i guess it wouuld depend if you want the powerjet to work in the top half of throttle, or just the top third.
