Bad Years?

I have a 02 FX470e also, bought it new. No major problem with it so far, after 25hrs one of the cam bearing just split but didn't give any further damage. At the same time I replaced the rockers for the 03 model with better rollers on them.
I adjust the valves after 5 rides and change the oil every second, Motorex 10W50 full synth. I had the suspension done after a year and from a mechanic of the(former )Husaberg GP team I received a good carb setting I now use. Just let me know what else you like to know.
I had a WR400 and found that the Husaberg had better grip coming out of corners so carefull on the throttle. At first I ended up in the opposite direction a few times.

Hi Javo:

The 01 motor was "all new for 01" and had a few issues. The starter gear required an immediate update and more than a few motors were damaged before the recall went out. Most of the e-starters did not work either for various reasons. The 02's are more sorted out. Be sure to follow the maintenance schedules and replace worn parts with the updated ones. Such as: Roller rocker assemblies, steel cam gear vs. your aluminum one, dual bearing counterbalancer and various bearings. For the most part the 03 parts are the update parts.

Stay tuned to this site and read everything

Congratulations,

Husabutt

I use it for Moto X only also, works for me. I now have 13-48 mounted which was standard but I will try 14-50 to make it a bit smoother.
The FX has longer 5th and 6th gear, the rest was the same. Oh Yeah, and an 18" rear wheel, the FC has 19".
Mine had the steel cam wheel already in it.

Early 2002 bikes essentially had 2001 motors. The upgrades that where introduced in 2002 where done throughout the model year and are often refered to as 2003 upgrades. Does the previous owner have maintanence records? Has the bike had any upgrades? The main things to watch for in my opinion are:

1. Cam follower rollers - the aggressive cams in these bikes chews up the rollers. Adjust valves often. Signs of shagged rollers are large change in valve adjustment. Plan on pulling the rocker assembly off and inspecting at regular intervals, while apart inspect cam bearings, rocker pivot shafts and bushings, and cam chain/sprocket. 2003 models had better bearings in the rollers. Husky rollers will retro-fit in the 2001-early 2002 rockers and give increased life (Husky and Husaberg are still very similar engines and can share some parts, same with the RFS KTM's). A Lineaweaver cam can up performance and help with roller life by decreasing the radical ramp speed of the stock cam. The main reason the valve trains in husky's and ktm's last longer is due to milder cam profiles, since the design is virtually identical.

2. Cam chain adjuster maxxed out. Pull the center bolt and spring out of adjuster, then remove the two mounting bolts. Remove adjuster so as not to extend. Once out slowly extend and count off ratchets. If fully extended cam chain and sprockets could be worn or adjuster needs to be lengthened(They are often short from factory). 2001-early 2002 had aluminum cam sprocket, replace with 2003 steel model when replacing cam sprockets and chain.

3. Main bearings changed from roller to cylindrical. Replace with upgraded part at recommended service interval.

4. Balancer upgraded to dual bearing instead of single. Replace at recommended service interval with upgraded parts, or remove balancer all together (Lineaweaver offers this service).

5. Cracked cases, by swingarm pivot. Mostly only a problem for severe duty usage. ie. Big air jumpers.

6. Kickstart stop plate comes loose. Clean threads with brake cleaner or rubbing alcohol, red loctite, and torque the screws appropriately.

and when it comes time for daily/weekly/monthly maintenance................

Wash it and then remove the stator cover to dry out the water that seeped in.

Tighten the spark plug and valve covers.

Remove and clean the air filter then take a very clean and lint free rag (or paper towel) and wipe out the oil accumulation at the carb intake boot.

Buy some extra stator cover o-rings and valve cover gaskets.

Help is always just a post away .

I knew I forgot to add something crucial to my post above. Keep that stator dry. Dry out even if you don't wash it.
