Ok my 4×4 is not working ,so I have checked almost everything and the clutchs are not to be activating. I have checked all the electrical and its good ,the magnets are both working ,but the clutchs are not grabbing ,my question is,,,, Could it possibly be the hubs? and is it possib;le for both hubs to be bad at the same time . I had a hilliard clutch issue when I first bought the bike ,I had 3×4 ,I changed the hilliard and it was all back to 4×4 ,now I’m 2×4 . Any other thingsI should be looking at,don’t want to spend money unneeded.
