Thank you Taffy !

But Less than 182 ?

The Husaberg (Promoto eshop) told me to use 42 or 45 Iddling jet.

Gabki · Nov 7, 2015

And please tell me Is the needle position ok (6th from the top) ?
And 42 iddling jet is right ?

Taffy · Nov 7, 2015

yes.

When is the needle position on the 4th (from the top) the mixture is poor ?

And when is mixture poor the exhaust is shotting or not ?

I have Husaberg FE 550 2004 with original (stock from 2005 husaberg) pipes and tube and I have FP exhaust ( the same as this: http://www.qubar.se/wp-content/uploads/2007/10/DSC_0026.jpg )

(Sorry for my English)

you have so much fuel that it isn't burning it off. you are a mixture of wet and super wet and that is why you get the flames.

Ok, thank you, but Why the engine is very hot after 5 minutes from start and the water is boiled ?

Is the FP tuned exhaust ? Or is it stock exhaust because in the manual is Main jet 182
Pilot jet 40 (I have 40, 42, 45) and Needle OBDVR 5th from the top, but when I set from the manual the spark plug is yellow.

When I set the Needle on the 4th from the top and use 42 Pilot jet and 182 Main jet i don't destroyed my engine ?

And last question is :

My set is 182 Main Jet and 42 Pilot jet and 6th from the top and when its dark and I turn 1/4 a gas I see hot and red Exhaust collector, Why ? Because it is a very poor mixture ? BUT Spark plug has very good brick color .

And How many turns on the mixture screw ? I use 2,5 turns

Thank you very much .

never go by the plug colour.

unleaded fuels ruin this old way of doing things.

most of your combustion is probably taking place in the exhaust. it is so rich....

Is it Fe650 or Fe550?
