Well, got it all broke in and running really good.  Only problem that I have is that it sure loves to boil the rear tires!!!  No sand here so i need to run holeshot copycat tires.   Pretty happy with how it runs.  But I personally don't care for the 87 ratio 4th and 5th gears.  I acquired a stock-ish 88 zilla and I like that gear spread much better than this one.  As far as the pipe, it seems to be rusting under the clear coat.   I am surprised that it is doing this.  The clear was cheap and I figured i would try it.  No big deal.  Can be blasted off and hot jet coated.  Elka had or still has a super good deal on shocks right now so I ordered a set of stage 3 shocks for it....That should make a big difference right there....
