HEY THERE ARE SOME GUYS USING CR 250 PIPES TO CLEAR THE RADS ON THE 500 AF CONVERSIONS. MY PIPE SEEMS TO BE VERY CLOSE TO THE RADIATOR. 1992 CR500 ENGINE IN A 2006 CRF250R CHASSIS ANY IDEAS?

Just curious, why would a 250 pipe not work? I havent set the pipes side by side, but from looking at them installed, the stinger outlet looks to be of similar diameter, and the beginning of the pipe also looks to be close in size. But, I am going going off a quick glance here

Imagine eating authentic mexican food for ten days after getting five stiches in your asshole to close it up. It might work but the results are not desired. Shit needs the right flow (adn pulses)to make the motor run properly.

Ever run a DG pipe? Same situation. It's way too small. My 87 had one. It'd idle, it'd snap the tire loose, it'd fall on its face at 4000rpm. If the pipe isn't scavenging the cyl there is a build up of spent gasses which will over come fresh fuel and it just won't run past that rpm.
