Im going to be building a stock cyl 4 mil drag motor. goin outframe pipes in a lightened stock chassis. I am hoping for mid to low 4's if possible. I am wondering if an override is necessary or not? If so which one? I will be running 300 ft sand maybe the occasional dirt but very rarely. Also not sure about carb size? What would you guys suggest? I am right at 3000 ft elevation. Any other input on setup options are greatly appreciated. This will be my first drag motor.

While I'm not going to say never....but it would very very, very difficult to run low 4's on OEM cylinders without an override, on a stock chassis.
If you're going to drag race, it is pointless on these bikes without an override and lockup...
Rather than start the whole thread up again, here is some good reading and different opinions on overrides.
A well built 4 mil OEM cylinder is capable of that kind of performance in the right hands, by a very good tuner, light rider, good chassis setup...

I think the general consensus is if you're going to only run 300ft, 2-5 is ideal. If you have the urge to run longer, say 500 foot, 1/8 or 1/4 mile, 1-5 is a good choice.

Thanks Dave thats exactly what I was looking for. I read that whole thread, whats the deal with your buddy that cuts overrides? I'm thinking a 1-5 would be more suitable for me.
