jetting

I just picked up a 450 and after puting a few miles on it I've noticed a flat/hesitation/sputter spot around 1/8-1/4 throttle. Got it in the dirt and noticed it hard to maintain smooth throttle in the rough stuff, very jerky. Starts easy and pulls hard, gets 60+ mpg DS it. I did notice if I...

My 300 bucks a bit in the 30-50% throttle range. Ive cleaned the carb multiple times with no improvement. I suspect I need to tweek my jetting. Currently it is still stock. I ride in VA, WV, MD and PA so sea level to 1500 feet? It idles perfectly and and accelerates very smoothly under heavy...

Picked up a tagged KSO FE 400 and it was puking gas like the float is stuck/leaking. The problem seems to be a worn needle valve (worn rubber tip) so I'm going to do a total rebuild replacing all the brass parts. The CD1 Type Idle emulsion tube was missing so that will be added and I'll drop the...

I have Taffmeister's kit in and I'm not getting good results right now.... 2006 FS 650C FCR MX 41 Full Ti Akrapovic system (db killer in) Sea Level Here's where I started: Main jet - 160 Idle jet - 45 MAJ - 200 Idle air jet - 100 Needle - 4th from top (OBKER needle) Starting jet - 85...

I have owned a '04 650 since May 2011. It arrived with just 37 hrs and it came with what some consider to be FS jetting, but I believe this to be NZ specs where there are no restrictions. The jetting came as 160mj, 200maj, ekr needle, 45pj and 100paj. I purchased one of Taffy's kits and...

USA TE250's won't be here until Dec or Jan, so need to build up some info while waiting. Anyone in other market who has taken delivery yet? I have no KTM 2 stroke experience and hopefully won't have to wade through an ocean of threads on KTMTalk and TT.

Is there a jetting table for the dellorto carbs like they have in the manuals with the KTM's?

Hello to everybody I Am the founder of Husaberg Italian Forum . I need help. What tipe of jetting do you have on yours Kehin FCR mx 41 ?? I have main jet 178... but maybe it still small. I am 679 feet from sea lever. Thank you.

Here we can share the jetting we have on the Fe650 Have the stock jetting but are going to fit a Taffy kit

Hi Last February I had the jetting set up at HMRacing because it just seemed to be off all of a sudden, after years of running smooth. Well, all was fine, then, a few months ago the SEM stator packed in so I sent it to sparks to mend. Now the jetting seems wrong again, On the first run with...

Is it possible to change the jet needle clip position without removing the carb? Looks pretty close to the frame... Thanks!

Hi Guys, I'm new to the forum-never knew it was online, so glad to find other 'berg sm fans! I'm in Oregon, so don't see too many here. I raced an '04 FS450 for a couple years, then sold it for some reason that made sense at the time (*******). I've seen the light again and stumbled on to an...

i have an fcr sudco 41mm carb. it had a 175 main jet is that to rich? i put a 170 in but i wanted to make sure this would not be to lean. also has modified air box and exaust

I bought a very low hours '05 FE550 last spring and have never been completly happy with the carburation. It has always started very easily, idled fine, accelerated cleanly with no bogs. The original owner had installed a R&D adjustable leak jet kit including ACL pump spring, raised the needle...

I've got a 501 with a dellorto phb 40 and a marving exhaust can. Does anyone have any ballpark settigs for this carb? Just bought t and fouled out the plug mostly cruising around (on the needle). Wot seems to work fine but it would occasionally miss/bog at part throttle. I dropped the needle one...

Hi guys, I bought an Husaberg FS 650e SM 2006 model recently, and installed a DOMA silencer on it (only the silencer, not the headers). The bike runs very well, a lot of power etc, but I thought maybe it would need a new jet configuration since it has the new silencer installed. What do you...

I'm starting to get used to my freshly rebuilt '94 FE350. I have put a lot of time on it clearing trails, where I'll ride a while, and then get off and cut limbs & vines for a while, but it's Husqvarna clutch keeps it from being a really good "finish" trail working bike (putting up and taking...

I am having problems getting this pig jetted right. Most of my riding is about 3-6k feet elevation. I am running 100 octane fuel and that is what I will always be running. I am having problems keeping it idling when hot and starting when it is hot. Can I please get some suggestions.

Hello.I am new to this,site although I have browsed to scrounge information many times. Bought a 2000 fe 501 a couple of years ago on ebay, motor done but needed a tidy up. Anyway tided it up went to go riding, stator failed (started ok at home). Bike sat for awhile (2 years) fixed her up and...

As i read some were on this site all husaberg come jetted to rich from the factory. I have decided to try to jett my carb to get better fuel economy, and do the BK mod. This is what my carb has in its gut. 160 Main 200 main air (MAJ) 45 pilot 100 pilot air (PAJ) fuel screw 2.75 turns...
