I have a couple of questions for you guys. First off I have a yz426 in a quad frame it is using the first generation fcr carb the head is from a 400, on the intake there is an air tube that is unused in the quad. If I hook a hot start button to this would it do the same thing by letting in fresh air? Also I just bought a set of cams with adj. intake and I was wondering how to degree the intake cam,What power band changes does advancing/retarding the came make?
