It depends on how u ride to I can bet a 500 ac and hang with a gizz 700 and ride right behind a raptor 700 just play around and see what works for you, me I get out of 1 as soon as the wheels start truning hold 2 for just a little bit then 3 for like 2 second hold 4 as long as I think I need to then 5 but I also mash the crap out of the throttle.
