Why dont you inspect your steering head bearings and adjust them correctly along with tightening the stem nut and road test again. A loose front end like that would no doubt cause problems that a steering damper simply can not mask.Tire preasure is normal , i think there is problem on head staring becouse when i am using fast break in front from front end of motorcycle there is a strange noise i think head staring need grease and its loosen , i will fix this problem but anyway i am interested with damper how can i check if it works ? Anyway such a big wobble is a bit fault of damper also becouse it must prevent such a big whoble even if stearing is losen not ?
Your steering damper is the last thing you should be looking at. What you're asking is same as being shot and asking if a certain bandaid will fit over the entry wound.2.3 bar front 2.7 bar rear
And what about damper is it possible to test electric demfer its working or not well ?
