Measure the I.D. of the exhaust port. That'll give you an idea of whether its been ported or not. I don't remember what it is out of the box, but most builders open them up more. Get a measurement, and I can compare it to one of mine. Quote Link to comment Share on other sites More sharing options...
lowriderb Posted September 30, 2009 Report Share Posted September 30, 2009 measure the sleeve side of the exhaust port, width and height from the deck. then measure the highest point on the transfers (which should be even across them) to the top of the deck. the casting flaws is usually all thats cleaned up in the intake runners.

RadarRacing Posted October 1, 2009 Report Share Posted October 1, 2009 You can send it to a reputable builder and they can check it out for you each builder does something different as far as porting. Quote Link to comment Share on other sites More sharing options...

LT ROOKIE Posted October 4, 2009 Report Share Posted October 4, 2009 I have a 4 mill cub with 39pwk alky carbs and run 6.7's @98mph in the 1/8 mile. I think 6.2s will be pretty hard with a 4 mill. If u want a fast drag bike that u will be satisfied with for a while build a 10 mill. This is my first drag quad. After three trips to the strip I am bored with the 4 mill..

kubitza123 Posted October 29, 2009 Report Share Posted October 29, 2009 You can't really go by those 5's your seeing on the 4mill. If they are run by who i think they are they are from PR. Also you really have to have a good nitrous setup and know what your doing to run that big of a shot and not destroy your engine. It can be done but by few. And chassis and everything else has to be setup perfect to hit numbers like that . Its not easy . Theres some DM'S That people can't even get to run numbers that low yet.
