RE: Dune Runner 4x4 Questions
Ive got the 2wd version and i love it. I got a non ported 28.9cc motor with a +2mm stuffed crank. Pushin 4.5+hp with a tuned pipe and it rips. Plenty of power with a stock clutch spring. With a higher stall spring it would take off harder but it already spins the wheels. Anyways i love mine and ive got about 4 tanks through it and everything is holding up awesome. nothing broke yet.
