As far as the motor goes in that video it was completely stock. I will be racing this weekend with the built motor, we are trying to see how fast we can make it with the stock piston on pump gas. So far I hit 89.7 MPH on the rev limiter with 22'' Maxxis Razr's and Tire Balls and stock gearing. As far as other mods go we put an Alba fuel programmer and HMF pipe. Most of our improvement is on the suspension side, the last race in Baja that we won a couple of weeks ago was done on a stock motor with a filter and a pipe our biggest benefit is the suspension set up we have hundreds of hours and thousands of miles into testing. And we have our whole package working so well with are Houser arms and Elka shocks it makes racing so much fun. As for the stabilizer it is an Elka, we are using DWT 11'' wheels , Maxxis 22'' tires , Renthal bars , Houser front end and stem soon to be Houser rear arms and axles , Streamline brake lines , PRM skid plate that is most of it.
