2.4 Circle Track!
Tuesday, May 18, 2010 5:54 PM
how many of you out there are running the 2.4 on paved or dirt circle tracks? Anyone have engine problems. I thru a bearing so motor is getting rebuilt and builder knows of oil problems with these motors! I am wondering if anyone has had good luck with these motors or what you are doing to make them last!?

You have to drill and tap some holes and drill a new feed hole. Search in the performance forum. Lots of pictures. A 2.4 pump cavitates (pumps air) at high rpm thus junking bearings and then rods. A 2.3 pump is the only way to make one last.
