Once again the easiest solution was the best. Had the front wheel balanced today (60gr ) and the wobble was gone!
The front suspension is great now, racetech spring upgrade was well worth the money as now the front feels as good as new.
Thanks for all the advices guys!
I can`t be sure if I allready had the problem before the rebuild as the front was in quite horrible condition, so it could have been there for a while but I just hadn`t noticed it. I´m pretty sure I installed everything back to their places, or atleast I didn`t end up with any "extra"-parts... :thum...
Yesterday I installed new Racetech .95 springs, new seals and Motorex 15W fork oil with the oil level set to 100mm from the top. Now after litle trial and error with setting the correct preload and sag the front suspension feels just amazing after riding with leaking pogo-stick it used to be, BUT......
The reservoir swap hasn`t done any damage. You should check the coolant for any oil directly at the radiator. If there is oil on the coolant it is definetly the headgasket. If the headgasket is broken there are quite few thing that may happen: white smoke from exhaust, oil & water get mixed = "baby ...
Your oil has water in it. Check if your coolant level has lowered, if it has your cylinderhead gasket is probably broken and your coolant gets mixed with oil (if so it is likely that the coolant will have a film of oil on it).
