Well first off. THANKS Dave! This is my 2 year with the Team but have been running Radical motors for about 5 years. I have 3 different types of heads in my motor box. Not much has changed on the inside. I run the glow plugs that Dave sells and the Radical pipe also. The inside of a Radical motor is a piece of art. Go to the web site and √ out the pictures there of the inside of the motor. Thanks again Dave for supplying me with a GREAT motor. Also Thanks to Mike Stanton.
