Back firing through exaust when COLD starting...08 FE450

Ok, just so that y'all know I DID go through the owners doc, previous posts, etc. before starting this topic.

When cold starting (below 30 degrees hey I live in MN!!) I have a loud scary back fire through the exhaust when using the e button. If I push on with the starter and twist the throttle I can get it started but I know that's not right and don't want to risk damge, so I need some advice please.

I have synthetic oil in (10W50 Amsoil) and would like to change it to 5W if I can get it started :evil:
Plug good, compression good, valves checked (I set them this fall), spark good, fuel 91 with Seafoam, I use the de comp lever to find TDC then give it a good kick as best I can I'm on the short lite weight side since I'm a chick with a Husaberg!! It does turn over great with the e start but I give it a break after a while and when it starts Backfiring 8O I do clear out the spent fuel in begining with de comp lever in and clutch in.

What Am I doing wrong? FYI I NEVER have trouble starting it off the e button in milder weather and it runs awesome, no bog, no backfiring etc. Also notice that the clutch drags when it's this cold and when I try to break things loose but putting in 2nd and bumping it the rear wheel just skids.

Husabutt, The bike has winter blend in it now (I used to work for Conoco ages ago). We start winter blends early since it's always so COLD here in the Northland. I suppose it wouldn't hurt to drain gas and dump in fresh yummy gas. I could put the old gas in the ATV's they burn anything and with FI they always start!

Ned, I'll check on my pilot jet setting...does this mean I'll have to pull the carb?

Thanks guys for the help, Colleen the Husaberg **** 8)

Ned37, Do you mean the FUEL MIXTURE SCREW, next to the idle speed knurled knob? That was my next check to see how lean that was set. Looks like stock setting is 1 1/2 to 2 turns out. I was going to try this when I went back up to NW WI this next week.

I'll bet it's accessible, this bike was a GNCC bike b4 I got it and the 2009's came out so they ran the new bikes. It has a lot of nice bits on it! I do think that I'm LEAN on choke when I try starting it...esp. COLD and that when I pump in more gas via throttle I can get it started but then the Backfire which is a no no. :roll:

Ned37, Yep I'm clear where the fuel mix screw is, but pics help! Looks like a common FCR/upgrade and I'll pick one up tomarrow at my local shop. Thanks you guys rock :headbang:

Here's the update, it turns out that I do have a Zip-ty like knurled knob style adjustable fuel mixture screw on the bike...Yeah! Looks just like your pic Ned!

I adjusted it richer by 1/4 turn to about 1 1/2 turns out as far as I could tell and that definately made a difference. It's fun trying to get cold fingers in there with the silly bracket for the idle speed screw in the way. After giving the bike a few warmup kicks it started off the button and only one complaining pop. I'll probably turn it out richer another 1/4 turn next time I'm at my property :wink: I changed the oil to 5W40 and it looks like I'm on the right track thanks to everyone here :bow: :cheers: :bow:
