Thanks Big Guy -

So it is all about timing and duration - I need t learn more about these little motors and the principals ..

I noticed you don't have the RB AR/Oil listed on your site you were showing me - should I just give you a call when I need some?

I'm going to throw that FMS with the different crank into my Truggy to see how it runs - I know the track is short but I am curious to see what it does - which of those pipes/header combos do you think would be the ..um .. tamest of the bunch?

So what bearing is that in the FMS use one of the 16002/4 or is it something different?
