TC 250 2010 starting problems.

[ray_ray]

Remember not to 'kick it like a 2T' and get a full stroke on the kicker also ....

I'm thinking the 45 pilot jet is too big. Our bike came stock with a 38. We put a 40 in it with the carb upgrade. I'd try going back to the 40 and setting the fuel screw at 1.5 turns out. If it still is hard to start warm, try closing the fuel screw 1/2 turn.

Also, I'm assuming you are not twisting the throttle at all when trying to start hot. Never twist the throttle when starting hot. This will surely flood the bike and make it impossible to start. Also, as ray ray mentions, it is absolutely vital that you kick this bike with a full, smooth stroke from TDC or one click past.

Have raced 4stroke since 2004, So i know "how to" start the bike.. The problem is something else... never kicked my bike's like a 2stroke.

Talked to some people here in sweden and there's bike's are great - without this problem = something is realy wrong.

And yes if you turn the throttle on a warm bike you are walking home
( Like now ) .


With 40 ( stock ) the bike "boogs" and missfires , with 45 it's just perfect, so if the bike just starts, it should run ok. But yes, maybe 40 is needed for it to start. But it hasn't helped the 10 hours i now have on the bike. sadly.

Will keep you posted, testrun in 2 days.

Sounds like my bike when I first got it...

Mine was VIN #88 and it had some major kickback issues. I got it with 4 hours on it and the previous owner hated it because it never ran right.

I messed with the jetting to no avail, it would never start warm without an act of god or push starting. I ended up having Bills MC plus in Oregon modify the cams. He smoothed out something on the cams to keep them from binding and causing the kick back. It was only supposed to be an issue on the first 150 or so bikes but it sure sounds like yours has the same issue.

Mine now runs great with the following setup

Updated carb bowl drain
Updated hot start lever
Fuel screw 2 turns out
185 main
40 pilot
JD jetting red needle in the 5th position
50 leak jet
thick o-ring on the accelerator pup arm

Later,

Any idea what Bill's did?

Decompression cam, maybe?

Tappet cam mod

My sons bike was binding up 2010 Tc250 ,almost locking up everytime the intake cam rolled to the edge of the tappets.So we pulled the cams in. & ex. and polished a champher edge all around the sharp sides of the lobes.Then we polished the top of the outer edge of the tappets all the way around so the tips cam lobes wernt hitting them and locking up.It worked!! before we did this the kickstart would lock and even bend or break the shaft in some cases.After this mod no more problems.
so now we have done this to several and it works .I saw in cases they locked up so hard they ripped the cam holder in half.
if need picks or more help let me know .MERRY CHRISTMAS !! billf

Wow, that's pretty wild. I'll look into it a little more, and I may take you up on the more help offer.

Thanks for sharing. I'll consider that a Christmas present. Merry Christmas.

thx for the setup tips!

Ran the bike today - without any problems! Started perfectly cold/warm and even after breaking stalling and crashes!

no kickbacks or anything - the bike was now a real blast to ride!

( the change was only a new CDI-box ) . and with updated carb setting and hot-start lever.

a little video from today so that you guys can se how's the wheater here in sweden is

Glad to hear you got things sorted out. The snow riding looks like fun.

 

[MOTORHEAD]

Looks like you guys need to run a snow plow around your track.

That's some deep snow.

 

[Wiegandt]

Half the track was plow'd and half wasn't

You can guess where i'm riding

 

[d251man]

thanks for advice

I have the exact problem with my 2010 TC 250. So the solution is the rejetting, and a new CDI? Or is the hot start mechanism the issue? Mine is bone stock including pipe. Mine kicks back, hard to start cold, stalls pretty easy, and left me pretty frustrated in a couple of harescrambles this fall. Thanks for any help here.

 

[Wiegandt]

how many hours do you have on the bike now d251man?

the updated carb setting was mounted directly when i got the bike, so i have no ide how bad it runs with the early stock setting...

The CDI-box was the fix for mine, but i have seen many other solutions.

I am running the Husky powerparts hotstart-lever now on the bike and it works best with it now i think..

I am also now running a heavier flywheel . It prevents the bike from staling and i think it even helps on the starting issue..
dont use the throttle when you hot start the bike, give it a couple of turns when its cold.. If this doesn't help, contact your husqvarna dealer for a new cdi-box or anything..

It's free!

Where are you from? I am not bashing CDN Dealers but it seems that most are not aware of the carb/jetting update kit available from Husq. The CDN Dist dropped the ball not getting this info to the dealers in a timely manner.

The kit makes a big difference. My TC started on the line 1st kick every single time.

I have the parts in stock if you need them.

Where did you get a heavy flywheel?

 

[gestion01]

I'm just back from Florida and put 35 hrs on my TC in 17days. It's starting way better now than before... I can get it started with 1 or 2 kicks hot or cold every time. Piston still needs to be placed before kicking or you will never get going. None of my friends can start it.

JD kit, with carb update hot start and float bowl plug. 1,5 turns fuel screw. (jd recommends 2)

 

[Wiegandt]

Where did you get a heavy flywheel?

Husqvarna said that there is no heavier flywheel to bye..
So this is custom made.

 

[MOTORHEAD]

Did you make it yourself or have it made? Do you have and pictures or details of how you did it?
