I have also seen the blue head GO 21 3 port for sale in the $67 range new with shipping included are both these motors (21/25)any good for Dirtoval racing. I race on a short track top end isn't that important but smooth power from the middle of the corner off the car needs a controlled slide. Most of the guy's I race with run Dynamite platinum series or regular Dynamite's I haven't seen any higher end motors out at the track that is why I'm willing to try a older GO 25.
I had to run a picco 28 (jammin28) yesterday and it was unpredectable it would get the car loose from the center of the corner to the exit of the corner it was way too torquey motor and had a little too much topend I was having to let off early to keep the car down on entry in the corner
My car ran great with a OFNA force 28 but I have a compression leak from glowplug so if somebody has a worn out force 28 I need the head PM me.

I would say most of the rod problems were from a really tight motor and improper break in. It looks like the motor you have listed is a sport motor, they do not have nearly as much pinch from the factory.
