air

I tried to correct a problem at 1/8 throttle (constant pace on a straight road) that has always plagued my bike. I tried everything PS, PJ, NEEDLE, but it was just a turn around. Then I started increasing the PAJ (PAS) and took it off completely this morning. Now the bike goes with 1/8 - 1/6...

I am trying to understand how this valve works on the FCR MX 41 of my husaberg 650. I have noticed that a spring presses the pin diaphragm which in turn opens a bypass which adds air into the pilot circuit, making it lean. A duct carries the vacuum signal on the diaphragm which overcomes the...

Hi I'm trying to deepen the jetting speech on my fs650 2007. I wanted clarification on the PAJ, which measures you use (I have the 100 but I don't like how the bike goes) and what should change

Just got this bike and discover there is little of none oil on the air filter under seat ? , is this normal or do I put air filter oil on it ? thanks , :

Wanted air filter wash cover for 2010 450 FX.

Hi! In the middle of putting my berg together, and as always when questions/challenges come to mind, i search the wisest for answers/ideas:) Due to some hp increase in my 650 engine, I feel myself in the need of giving it some more air - or lots of it...;) I have been thinking on...

Hi all, I just bought a 2006 FE550E, it's my first 'Berg so I don't know a lot about them yet. When I bought it the shock felt nice but the forks were REALLY firm, there was no 'bike sag', barely any rider sag & the bike skipped off anything the front wheel would touch, there wasn't nearly...

Carb inlet to AF boot, part # 80006026100 Part # 80006026100 boot connects the carburetor inlet to the air filter flange. KTM has discontinued the part. It fits my 2007 FE550E. Does anyone know of a boot that fits properly as a replacement? Thanks.

Hey guys! I'd like to ask where can I find this coolant air bleeding screw? I dont find a proper manual for fe470 2004, heard that it must be close to the spart plug but i dont see any screw there. Could somebody please mark it on the pictures I sent below from both engine sides? Thank...

Hello berg lovers. I need your experience about carburator jets. After I have installed akrapovic exhaust and DNA air filter on my fs650e I began to feel the bike a bit strange and low throttle response. I have pushed the acceleration pump a bit and looks better. Couple of days ago a guy with...

Hi, Anyone have tried this hardware on a Husaberg Fs650? Looks nice. https://www.twinair.com/off-road-performance-accessories.php Thank you

Looking for some WDS forks? Prefer vgc radial foot for sm caliper, axial mount would also be considered

Anyone got a left hand exhaust header pipe for 501/550? It's for an 02 FC550, but I believe they're same for all years 501/550cc. I've got one but the sleeve section that fits into the cylinder head is gone from the L/H one. Maybe I can get a bit of tube welded on, but would be much simpler if...

Does twin air make a preoiled air filter for 09 450? are there any other preoiled recommendations. Thanks

Hello, I am new to this so go easy! My cousin bought a 2015 FE 450 on Saturday, it had done 50 miles from new, anyways drives it back (less than 300 miles now) all good. Next day spotted it had been leaking, so he's started looking and took out the air filter and it looks like a mix...

Hi all, took my carb (FCR 39) off to change the jets as a couple were wrong. Adjusted the float as found this was wrong too and set it to 9mm?? Put it all back together and now have fuel in the intake boot so adjusted the float back to see if that sorted it but still filled up! Could anyone...

Hi This is the carb in my 1997 FE400 It's a VHSB flat side By the locaition of the mix screw it should be a air screw correct ? Meaning that turning in will enrich it and out will lean it ? Thanks Nuno

I have removed my air filter to discover there's a layer of grit/dirt inside the top part of the air box in the inaccessible part of the frame and worryingly close the the hole at the top and the engine vent hole which I can only assume runs straight into the engine, the wierd part is that here...

I've been using either HiFlo or Twin Air filters. Does anyone use other brands? and are they pre-oiled?
