Last few days my husaberg 450 has been a nightmare to start once its warm, keeps spitting huge flames out when im trying to start it aswel. But when its cold it starts perfect, any ideas? Thanks

What is different when warm: valves get tight, check quickly when cold with you thumb and index finger. Ie click up and down on all tappets. Note if too tight or too loose. Do a proper air screw adjustment. Then change the plug no matter what it looks like. Oh turn the fuel off and then on with choke and see which one starts better?
Let us know what happens?

A quick check to do. (Especially if you are broken down somewhere).
Remove spark plug and tighten electrode gap to a nearly touching, If the bike starts you have just diagnosed an electrical issue.
I have used this many times on Canam, Yamaha, Husaberg etc.

I adjusted valves as shown is this youtube vid http://m.youtube.com/watch?v=TnKYEbRzKic
And now it wont start at all ha ha! I've also put a new iridium plug in
What year is your bike?
Did you set the valves on TDC compression? Sounds like you set them on overlap if the bike will not start at all.

Hi Pablo
Again, check the carb, if you have some air passage clogged and making it too rich, maybe the engine can live with it cold but when hot probably not.
Just a thought ... not so hard to do ... and a clean carb never hurts :mrgreen:

Does sound like values not sealing, check that you had the decompression lever not effecting that adjustment. Failing that it could be the stator particularly if sem type. They when damaged could start perfectly when cold but not when hot. If you stall when going slow this may point to ignition. What I mean is why are you starting the bike when hot? Is it choice or due to what you think is flaming out. One more thing, take the air screw out and make sure the o ring is not torn. That simple thing could be the cause.
