Hi there again,
interesting dicussion, anyway.
From the mechanical point of view there is no doubt that a 03 model has nearly the same reliability than a 04.
Maybe, and that shouldn´t be understand as bad critics that a Husaberg becomes more and more a KTM, the crankshaft is now made by Rotax like the KTM one, and the cylinder head is very similar to the KTM one.
If this is an advantage or disadvantage I don´t want to value.
Surely, the engine has been improved every year to become more reliable, but since
2002 the mechanical side of the engine is very reliable. You can´t compare a sportmotorcycle like a Husaberg to a Honda XR 600. Obviously a XR 600 doesn´t need the care that a Berg needs. You have to maintain your bike carefully and regularily. It´s only allowed to rev high a warm engine, change your oil often, check the valve clearances and always ride with a cleaned airfilter and you will have much fun with your Berg!
From the electrical point of view there are some advantages. The 04 ignition is better. Mikst you´re right, the KTM Kokusan ignition runs in oil and the Husaberg one is running dry.
Some people had probs with the Kokusan when getting hot (me too), the soldering joints were smelted, but you can resolder it very easily. So the stator is repairable and you don´t need to buy a new one. A SEM stator is
not repairable, at least it´s not possible by using normal tools with normal skills.
So, if you get a 03 as bargain, then take it. I think you can buy a lot of SEM stators and Keihin carburettors for the money you saved.
I wish you many many hours of fun with your new bike.
best regards
