Hi mi husaberg 450 is not reving .

carb cam valvs and intake are ok

the stator is new and al the values ar spot on when messuerd.

so stator to is ok

timing is spot on when its on idel

this is how it sounds when i try to give it gas (rev it)

the sparkplug is perfeckt colur when iv had the bike standing on idle for a litle time but as soon as i try to rev it the sparkplug gets black and bad .. so it is getting fuel.

and the bike is very easy to start and runs whitout choke

watch the link and pleas give some advise.

first thing i would do is pull the carb apart, check to see if the needle clip is still in place and while you are there, look over the slide. also see if the main jet fell out.

hello

carburetor has been disassembled and all parts cleaned in an ultrasonic washer.

all parts in the carburetor is good and right.

the bike has previously worked with the stator.

stator is an aftermarket one.

have somewhere read that these can burn the cdi

so the carburetor is unfortunately not the problem.

have tested it whit shokes in and out but still the same and
I have tried to spray starter gas into the carb but still no difference
this shuld have given it a litle more rpm if it was a carb issu or am i wrong.

but thanx for the replye

evidently you have the odd year. what ignition was original? sem? did you change it to an electrex? if so, then you have probably just answered your own question? what carb does it have?

mansa

i dont have the name of the carb but its the one whitout electric pluged in to it,

the ignition system is SEM and cdi is stil oroiginal SEM the stator is a replacment for the sem so it bolts on whitout mods .

the bike has worked perfect whit this setupp . so somthing has changed inside some part probobly the cdi but im open for advise on other things that can do this to the bike.

did you check it with a timing light to know timing is correct at idle? if so when you did that did you try to rev it then and watch the marks advance, the cdi box is the only thing that advances the timing, its at idle or it its advanced thats all you get. with a timing light you will see the mark then you wont if you rev it when you look through your little hole thing on the stator cover, i dont have a hole on my stator so its different for me and i dont know you exact timing procedure. i do agree with you it doesnt sound like its advancing or like ned said your needle isnt attached to the slide anymore but i think it would go very lean and stall, definatly wouldnt make your plug black at this point....i would watch the marks with timing light to see if it doesnt advance, if it doesnt then its the cdi and if so then you may want to think about the correct stator so it doesnt ruin your replacment cdi coil. i have had carb issues and have had base timing issues but with either one the timing still advanced properly when watching with a light. this problem started all of a sudden? it wasnt just all taken apart or something right?

yeas i have cheked the timing whith a timing light and in idle it is wher it suld and when i rev it te timing advances but sems tu be jumping al over the place so i think its a cdi issue .

the bike have bin apart but we have cheked al moving parts and marks are spot on when its in tdc so this is the reason i think its electrical.. iv tryed disconnecting al cables exept the ones you need to run the cdi . still no god

I think that it is the stator not producing enough ooomph!

check the numbers

red to black at least 2750 - anything less and your in the amber zone where the bike does just like yours is.

Hi Mansa,

Very unlikely to be the cdi, these were the analog type, they either work or they don't, I've never seen anything in-between.

What make of aftermarket stator do you have?.

what about electrex stators, do them really burn CDI?
