The engine has had some port work I did and basically a straight through exhaust with a well tuned NT carb.... 9000+ RPM several times but I tey to keep it toned down a bit so it will last a while longer.
On a basically stock engine 37mph with a nice cruise speed at 32-34mph is not bad.
That's true as long as I can keep with traffic I'm fine "you can only push a china girl so far"
