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 The previous version was outdated and no longer supported.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

TC 250 2010 starting problems.

Hello guys. Im desperate for some help and i hope that you can help me.


I bought a brand new Husqvarna TC 250 2010 for a couple of months ago of a Husqvarna dealer here in Sweden.

Everything looked ok, but then the nightmare began..

The bike is almost impossible to start when it's race varm. If you get a sudden engine stop , or take a brake for 10 minutes the bike is almost impossible to start.
NOTHING happens when you kick like crazy. No ignition. Nothing.
The only thing you get for a reply is that the kick "kicks-back" with a hell of a punsh!

This happens about 3/10 times when you try to start the bike.



When the bike is cold, it start's rather easy. ( Not super easy ) . If you turn it of. It might start again in 1-5 kicks, but it might take 30-40 kicks!

Husqvarna said that the bike would get better after 10 hours. But the bike have now ran 18 hours and nothing have rely changed..
The bike runs EXCELLENT when you well get it started. No boogs or miss-fires or anything. Great bike. But, when you get a sudden stop you can just leave it there......



I have spoken to the dealer and Husqvarna Sweden for advise. And this is what we have done:

* checked CDI-box ( some problems with some models. OK model )
* 2011 ignition-cap ( new part number, looked the same to me ).
* Updated carb-settings are mounted.
* Tried 3 different "hot-start levers/buttons".
* valve checked everything ok .

Husqvarna is out of ideas and so am I..
I have always run Yamaha 4stroke before this bike. And i hate to here the word " - i told you so " of my brand change..

So please. Help?

Its too rich...and 4 strokes when they are hot wont tolerate a rich condition.....

probably need a smaller pilot and/ or the fuel screw turned in a bit...

also the float may need a slight adjustment to lower the fuel level in the bowl....I personally like it 1 or 2 mm below the spec

I know what its like to be pouring sweat and out of breath..and it still wont go :banghead:

dont think for a second you bought the wrong bike.....its just a carb issue
 
Thanks for the tips Collins.

But i don't think it's a carb issue (?).
We changed the low jet from 40 to 45. Because of some miss-fires and for not the right "go" in the bike. I have never had a carb bike that runs so good! So i belive the jetting is pretty good. Motocross action runs the same jetting..


We have played a little bit with the fuel screw but in -20 minus here in Sweden it's rather difficult. But the bike runs great as i said, and starts pretty easy cold but with some "kick-back" - why is this ?

It just feels like a ignition problem and not the carb. The bike dont even make a sound when i try to start it warm, except for some "kick-backs"...
And yes. Its fun to stand there like a fool in race and just kick like crazy :)

my dealer will try a new CDI-box in a few days on the bike. And change part after part..Stay tuned..
 
It does sound like a rich condition...reguardless what Motox mag said- everyones atmostsphere and experiences vary... just for fun, next time you get it to that running temp where you know it will be hard to start it- shut it down. Then turn in the fuel screw 1.5 turns or so... then try to start it as you normally would. If there's no difference- then I'd continue to pursue the spark issue. Take off the tank and inspect the coil connections and clean and retighten the coil ground. Ensure the spark plug cap and wire are properly assembled- tight. Give it a new spark plug. Then see if anything changed.
 
I believe Troy is right. My 2010 TC 250 is very sensitive to fuel screw settings. I installed a flex jet remote fuel screw and set it to 1 turn out. As it gets colder, I tweak it open about 1/8 turn for every 10-20 degrees F decrease in temp.

I can't remember what pilot I'm running but I think it's a 40. My bike has the carb update kit from Husky installed. Kickback would occur on my bike when I was trying to start it too rich.

Another thing to consider is your kicking style. These bikes don't like being kicked like a 2 stroke. My method for kicking, hot or cold, is to start from TDC or one click past TDC and give a smooth firm kick all the way through the stroke. Do not "jab" kick with quick short strokes.
 
thx everyone for the support .

I will try everything you guys said tomorrow!
Krieg - You have the bike so i trust you for sure! And when you talk about it , it makes some sense.

I am running 45 now due to the cold. 40 is stock. And like i said, the bike needs it and throttle respons is awsome now!
I will try to do some changes tomorrow and se what comes up!

And i have rode 4stroke now since 2004. So a big punch al the way is the right way that i know :) . If i try anything else he will kick me off :)

Thanks again for the support!
 
I just looked and I'm running close to what MXA says they are running. I have a flex jet and I'm about 2-1/4 turns open. I also installed a adjustable leak jet and I have it down to where it's about equal to the 35 leak jet, to get the bog to go away.

Most of the time my bike has gotten to where it starts pretty easy, but I'd have these occasions that it would just die and wouldn't relight on a bump start. Then I would kick my brains out and it wouldn't start. I'd get wore out and just set there a bit and it would fire right up.

To make a long story short, I tracked it down to what appears to be the check ball in the gap cap. I simply took the ball out and it hasn't happened again.
 
What is the last 3 digits of your VIN? I am positive that Husky has changed the cams from the first build to the later ones. My bike was 192 and my buds was 18. My starts perfectly and his is a SOB with the exact same jetting. We switched cams and his starts up right away.

Go figure... ours is 059 and we've never had an issue :excuseme: I wonder what the cut-off number is suppose to be?
 
My 08 TC 250 was a night mare at first.......it used to shut right off on a jump landing..or hard braking area....then everyone you worked on so hard to pass....just rode right by while you poured sweat trying to start it...tell that was a bummer gang :banghead:

lowering the float and leaning it out a bunch...made it perfect
 
Mine will only start with the piston positioned perfect. You could crank all day and it will never start if you don't do it right. When its cold I also need to give it exactly 3 full throttle turns...not 2, not 4.

Very finicky bike to start. I tried just about everything. Rumor is a kawasaki carb will cure it. Which one I don't know.
 
A little update :

Got the bike back from the dealer a couple of days ago after several testing from there mechanic. A CDI from a great working tc250 10 installed , and they said that the kickback from the kickstarter was gone and the bike ran good. However they don't have the opportunity to testride the bike race-warm.

After getting the bike back it started a little bit better i think. But then again, no.
The bike started ones and died straight away due to the cold ( my fault ) .
Tried to start it up straight away and it kicked back like crazy..

I prepared a big hole in the backyard to berry it the next day......

But then it started on the second kick, and everything was fine.
Ran the bike warm and everything was great!

Tried to start it a couple of hours later, and then it was stone dead - again....

Started after about 50-70 kicks. Fired up warm again after 1-5 kicks.


I will try to testrun the bike this weekend. Due to the snow it's rather hard right now..
But i think the cdi-box change didn't help. The carb setting is checked and rechecked. And propper working..

Out of options, and tired of a brand new bike from 2010 is this bad...

What pilot (idle) jet are you running? What is the fuel screw setting? What is the temperature and elevation where you are located?

stock 40 , running 45 = runs better, better throttle respons. Everything els is updated/stock setting.

temp is right now -10 celsius , but have tested the bike from +20 to -10 . Just some adjustment on the fuel screw was needed..

But like i said, it's to much snow right now so the bike have mostly been tested indoors.

Have the shop check the decompresser hair spring on the exhaust cam.
