[keifer185s]

I was just wondering what the speed would be on my 1983 185s if it was tuned perfectly and running good.. I have had it at 80k but i was wondering if it would go faster??

Not sure how fast 80k is but i hat mine topped out at 45 with stock exhaust and gearing
And 53 with a straight pipe and air box delete.
