If you don't already have the service manual, get it here:

HUSABERG Pure Enduro - Older Documents

Download everything you can find that will be of use... we don't know how much longer it will be up on that website.

Oil - 5hrs is quite short for the oil changes. No harm there, just $$. Also, the oil filter doesn't need to be changed everytime, but again, if you have the $$, do it.

Valves - Frequency as per manual. Every 3rd oil change is a good bet (talking 8 hr oil changes). If you want to do more frequently, no problem. More frequently will ensure that your valve train doesn't get a hard time with tight adjestments (or too loose).

Special things to watch for - There is nothing too crazy to watch for. If you have a breather mod done (top of crankcase), then watch for oil spilling everywhere at high revs. If no breather mod done, then watch for excessive oil entering the airbox at higher RPMs.

If you start hearing weird noises, common issues are the bearings on the balancer shaft and cam chain rubbing on engine case (too stretched). If there are weird noises on starting, the starter gear (sprague) has issues.

As always, watch for foreign materials on the drain plug, in the oil screen, and in the oil filter.

When you are taking the clutch cover/side case off, be super careful not to disturb the kickstarter shaft. Keep it pressed inwards. It has a tendency to want to push itself out of the engine slightly... once it does it wreaks havoc inside the engine. Just be sure to keep positive pressure inwards on that shaft when doing anything with the side case off. To access the mechanism in question, the clutch basket must be removed. If it feels weird, pull the clutch out and check it. Better safe than sorry.

Lots of discussion on oil, but the main concensus is that high end oil is preferable and more frequent changes are preferable... so strike a balance between quality and frequency.

Piston, bearings, camchain - These are usually good for 100-200 hrs (or more in some cases). The piston shouldn't really be an issue unless contaminents get in there (dirt, carbon, etc). Bearings... the main crankshaft bearings are sometime troublesome. Again, watch the drain plug for any weird materials. The balancer shaft sometimes has bearing issues, but it is truly case by case. Since 04, there is an updated balancer shaft (one large bearing instead of two small ones). No concensus as to whether Husaberg changed this as a result of a design update or due to parts availability. Camchain... replace it every 100 hrs or sooner. Go off the service manual if you like... but a chain is cheap and it is very important to engine longevity. A new chain will help the valve system to stay timed properly.

Some months ago I was "retarded" when it came to maintenance, but I did a lot of research and tore down my own engine without issue. It is an easy bike to work on if you're motivated. Tooling isn't too specialized. Most stuff is available at the hardware store... or can be improvised. The parts are getting scarce, but Taffy has tons of stuff and is a great help. Check out:

Taffmeisters - Husaberg, KTM, Husqvarna, Gas Gas, dirt bikes - servicing, tuning, rebuilds, parts

Overall, you seem to be very cautious which is a good thing I suppose. Ride it hard and have faith. Oil changes are your best friend for longevity in these beasts.

All above info from a newbie... but a seasoned newbie.

Öljynvaihto 5h välein on ihan ok, jotkut vaihtaa suodattimen joka toisella kerralla. Se pitkä ohut metallinen öljynsuodatin joka on öljypropun vieressä kantsii paineilmalla/tms puhistaa aina kun vaihat öljyt.

Venttiilit kannattaa tarkistaa 30-40h välein, riippuu ihan, että liikkuuko ne välykset. Puhtaalla ja öljytyllä ilmanputsarilla on iso vaikutus pysyykö ne välykset kunnossa ja muutenkin yläkerran kestolla.

Koneesta kannattaa tarkistaa venttiilikopasta niitten heilureitten laakerit jotka tulee nokka-akselia vasten. Englanniksi näitä kutsutaan cam roller bearings:ksi

Myös kampiakselin päittäisvälys kannattaa tarkistaa varsinkin tässä mallissa. Ota staattorin koppa irti ja koita työntää ja vetää vauhtipyörää sivuttais-suunnassa, välystä kannattaa olla noin 0.5-1mm ylös-alas välystä ei tietenkään kannata olla. Jos päittäisvälys on liian pieni, kampiakseli työntää petilaakereita sivuttaissuunnassa kun se taipuu ajossa, jolloin se paskoo rullalaakerit nopeasti, josta samalla usein lentää metallihileet männän alle joka raapasee sylinterin samalla naarmuille.

Nokkaketjun kunnon voit tarkistaa ottamalla nokkaketjun kiristäjästä sen keskimmäisen pultin pois ja ottamalla kiristäjän sitten irti, siinä kiristäjässä on sellanen tanko jossa on lovia, mitä enemmän se tanko on ulkona niin sitä kuluneempi nokkaketju. pitäs jos on yli 7-10 lovea ulkona niin kannattaa vaihtaa nokkaketju.
