Hi M900 97 I would like to tidy up the engine casing and touch up the frame Not looking for concours finish, still like to retain the wear n tear, the casing and frame streaks really bother me, getting the bodywork, tank sprayed , just want to take edge off it
No idea , was like that when I bought it but as far as I am aware it is from the battery overflow spilling down but I have an AGM battery in there so not an issue
Fairly common on early Monsters and often as a result of somewhat exposed alternator and rectifier connectors suffering corrosion resulting in overcharging.
I would still buy an M400 if I could find one at the right price, last one to be crossed off the list, the 400SS I had was glorious at 11,000 rpm (factory indicated red-line). I only sold it because I was aware I was wearing it out quite quickly, you needed to change oil at 2K or less to be safe.
