I Am having a start problem with my Husaberg FE400

My bike starts very bad, especially with cold or semi-cold engine..
My procedure:
-Both fuel loops set to 'on'
-Pull my choke out and twist it 90 degrees so it stays 'on'
-Switch my contact key to the right
-Press my foot on the kickstarter, pull my manual decompression switch, push my kickstarter +-10cm down, let it come back up and kick it all the way down.
But this won't have anny effect??, I was't able to start the bike one time with the kickstarter...
If I try to start it with the elec starter it is very hard too. But when it runs af a while it does run very smooth and there is just no problem at all, I dont hear any cracks or odd sound of the enine.

Can this be my sparkplug which might be worn?
Or do I have to ajust my valve's play?
I tried to get my sparkplug out of my head, but i can't get to it with any tool?? My special bougie tool can't get in the head??

I did already read the 'hard starting guide' and will clean my carb and check my valve's tomorrow..

Apparenty there art a number of 02-03 dellorto equiped 400 models that are missing the emulsion tube above the pilot jet.It results in the symtoms you describe.Worth a check for sure!

Ok..
Where can I find that emulsion tube?
I need to open the carb itself or can i see it from the outside?

FE400s are notorious finicky starters. Keep the battery fully charged. Mine stays on a battery tender at all times. When I kick it over cold, I pull in the decomp lever, 2-3 kicks, release lever and give it a good mule kick. this works 80% of the time. The other 20% take two healthy kicks.

Thanks for the advice.
Do you have any explanation for this worse starting issue?
Is there a fix for it?
 
RE: Re: RE: Re: RE: Starting problem Husaberg FE400

theres a thread somewhere about problems i had with my '03 400.
at the time i was ready to dump it in the street and set fire to it.
tried everything.
then found a local chap who was husaberg trained. gave it to him for a morning and it was sorted.
what he explained was that there was no 1 thing that was really out of whack but several small things that were very slightly out and this meant it wouldn't start.
if i recall the valve clearances, decompressor settings and carb settings were all very slightly out and the combination of the 3 caused the problems.
this could be another cause of your starting problems.

my advice though would be to get it going then swap the carb to a fcr39. about the best mod you can do

Hee Snorremans,

I have the same bike.
It had the same problems and it is not really one item that goes wrong. Sarting with this model is poor anyway and what you can do best is to keep it in perfect condition. That means set the valves regularly, clean the carb, especially the idle air circuit, change the sparkplug cap if you don't trust it and make sure the ignition is OK. Check the resistance values of the ignition coil. But the best advise is indeed to get rid of the dellorto. With a properly set up keihin it starts and goes so much better.

Thnx arjen.
I will clean the carb this evening and set my valves if I have enough time..
I was looking for a Keihin FCR39 but i can't find it second hand.. And a new carb is too much $$ for me.
I saw a Mikuni TMR40 (is a carb from a ktm 640), can this be a good alternative for the dell 'orto?
 
RE: Re: RE: Re: RE: Starting problem Husaberg FE400

no.

keihin FCR or nothing.

i'll keep an eye out for you on ebay.

The FCR is the way to go.
Unfortunately, i have to share it between my KTM620 and the Husa! So at the moment the Husa is running with the Dellorto again. (The dellorto is even worse on the KTM....)What helps a lot by starting it from cold is to lay it on it's side untill the petrol flows out. Don't tell the Green Party though! Just like the good old days when you had to push the float of your Bing or Amal down untill the petrol came out of the overflowtube.
And keep your fuel taps closed when transporting it on a trailer.
