For the tow. I was burning fuel in prep of pulling the tank, about 25 miles from home. Tach dropped out, hit the passing lamp and got a quick engine cutout. Death followed at the next stop. Is it the battery (1.5 yrs.) or the aforementioned charging sys mods (not done)? A few mins on the trickle and she fired right up. I rode this bike to the MOA last July with no issues.
