What's up dude The problem you have is in the setting of the koso copy speedometer, this motorcycle has 2 coils (not like modern motorcycles that have 4, 1 per cylinder, yours has two, one for cylinder 1 and 4 and another for cylinder 2 and 3 ) and you have to adjust it to two coils, you will see that it will work well
Thanks for sharing your thoughts! Ride safe!!
