I'm in the infant stages of planning a complete mx build that will most likely be done in a Laeger or Lonestar chassis. Curious what all you trail and mx guys are running for motor and pipe combos I've had a stock cylinder unported with FMF's and T5's, ported stock cylinder with T5's, Stock cylinder 4mil with Shearers, and current setup on my duner is a 421 ported Serval with Shearers. I have dyno charts for most of the motors I've had so if you have graphs of yours, it would be cool to see for a comparison. This will be a long build so I'd like to get an idea of what potential engine and exhaust components I should keep an eye out for. Thanks.
