Roker Arm and Follower Bearings Trouble (see images)

This is from my Berg which was purchased 14 months ago brand new. I have meticulously changed the oil and airfilter all the time as well as regular valve clearance checks performed by Dealer. No warnings and this is what has happened. I have done 3000kms on it so far. I am chasing up Husaberg Australia about this and will keep you all posted.

As you can see both the Arm is no good nor the inside of the follower bearings. I am looking at having to purchase 1 new arm and 2 new follower bearings.

You may want to update now to all 03 rocker arm assemblies at this time. As you are probably aware of the 01-02 rockers are prone to failure and the 03 update is the cure.

Sorry for your misfortune.

Why does my dealer not know this I asked him about some sort of 03 update and he said there was none said the roller bearings etc are all the same code. I also took him the sheet Taffy has worked on earlier and he seem to think it was all a load of rubbish. I am unsure who to believe anymore. What am I to do?

I suspect that the 01-02 part numbers are superceded to the 03 part number anyway. I am pretty sure you must get the 03 complete assemblies though. That is you may not be able to put a 02 roller on a 03 arm or vice versa.

If your dealer doesn't have this information kindly tell him. I have an 01 470 with a lot of hours and no failure yet. I try not to rev it. Thats the key. Rev's take their toll.

Get both 03 assemblies and you should be in good shape. Easy on the RPM.

P.S.

You may want to add a Lineaweaver cam as it will help extend valve train life. If you ride on the street and rev it a lot one of his cam grinds should fit your riding style and help with wear & tear on those new rockers

I have the KTM numbers in my gallery for the updated rockers. They seem to be a little cheaper $$ from the KTM dealer. I imagine the cam is damaged as well, it might be a good idea to go with one of Dales cam grinds as stated.

Why would my cam be damaged?
Is there any way to check (will tell my dealer how to check it).

The cam is part of the equation in the problem. The severe "ramp up" as Dale calls it, of the stock cam, contributes to the pounding that the valve train takes. Dales cam smooths out the opening and closing of the valves.
B.O.S.S. (Bozarths Offroad Service Specialists) of this site puts 05 cams, cam sprocket and timing chains in the 01-03's.

What does the 05 cam give you? Did they change the profile?

The 04-05 rockers are different from the older bikes(At least one of them is). KTM's use the same rocker as the 04-05's.
