So I have a a 1980 honda hobbit with a proma exhaust and dr kit with an 88 jet. (yes I know typical) and everytime i seem to ride more than 10-15 miles it will either lose all power and die slowly or just cut out and will not start for a while after. But after I wait say 1 hour it'll start right up, but it will run rough at full throttle for a little while. The rough running goes away quickly tho. Is this a sign of over heating? and if it is how to I run it cooler.
