backfire

Dear members, I'm having trouble with my 2010 Husaberg FE450. I've got the bike for a couple of months now but I'm facing some problems I can't solve... It all started after I washed the bike. The bike started to stall and I've had difficulties to start it again. After I dried the air...

Hello reading this forum for a while but this is my first post as i have found all the answers i needed without asking up until now but now I'm stuck. I have a Husaberg FE450 from 2009 with 101 hr on the clock that cranks but wont start. Last time i used it it started almost perfect and had...

Hello again! So I have bought another 09 FE450 after few years break on a two stroke, as I liked the previous one so much and never had any issues with it. This one has about 200hours on it and I have maybe done 15, but it always had taken a few more revolutions to start than the previous one...

Took the 570 out today. Should not that it is a snow bike and I've taken measures to keep the engine at or above 150F. (primary cause of most snow bike failure is a cold engine) Anyways rode out to a friends cabin. 10-15 miles. ran fine. tons of power as always. Shut the bike off to go inside...

Update: problem solved, thank you all for the help! Changed the fuel filter and cleaned the injector, ran better but not perfect, borrowed a "know good" injector from a friend and it run perfect again. Did a few more tries to get my injector to run but ended up just buying a new one, can´t let...

Hey Guys, just bought a new to me 2010 fe 450. Had it out this last weekend and noticed it backfired quite a bit on deceleration. Checked the exhaust and I dont feel any leaks. Any ideas? Thanks in advance :occasion5:

Hi Guys, Got a question, my 2010 berg sometimes likes to pop from the exhaust, most of the time it does it when engine is nice and warm, it does it when I ride it and roll in gear with throttle shut for about 20-50 meters and then sometimes when I open the throttle or even without it just...

Hi guys. I'm kinda desperat. Today my bike died when i stopped at the gas station ( i full fueltank.) When i tried start it did backfire and was hard to start. I put the bike in 1st gear and rolled it back and forth, and after a while running the starter it finally startet. Later i got simular...

This problem developed on my 04 fe450. When starting cold, the engine will kick back starting and runs very rough after it starts for about 10 minutes. More time that the choke is needed. Then it is like a switch is flipped and the engine will run perfect and the bike will start smoothly. If...

2011 fe 390 with just over 3 hrs of life. I get a backfire at low rpm and applying the throttle. it has happened 5 or 6 times. Any ideas?

I have a 08 450 and have had this problem once about 8 month ago and now. I have been riding in the bush fanging and it's all going great then. Everything is sort of ok but the exhaust noise change to a bbbeeerrr and it's gutless when giving it more than say 1/4 throttle or more then it just...

I have a FE 350 that runs well but when I rev it and let off the throttle it backfires which doesn't really bother me however it also blows a small flame out of the tale pipe that can be seen in dim light. it has the Big Gun exhaust on it and i wouldn't be shocked if there is some small leaks...

Hi, I hit a rock the other day, see pic, quite lucky i guess. There is a quarter inch dent about 1" diameter behind the carbon shield and the bike now backfires a lot. I loosened off that section of pipe at the sleeve and unbolted at the head and noticed the seating is distorted between...

hi I'm new here i just brought a 98 600 FE off a mate of mine but when you open the gas and snap it closed it does a large backfire and blows the carby off the intake this is my first dirt bike in many a year so my trouble shooting is a little rusty for 1500 bucks the bike seems ok it just...

Finally I'm starting to get the jetting on my bike good. Only some small problems to solve that I know you can help me with!!! :D My bike was a bastard to start hot or cold. After some tests I found out that the bike was getting flooded with gasoline, That is now fixed and she starts nice...
