yep these motors can catch people out thats for sure with this needle just by the advise people have been saying and the tuning tips on massive mods web site is dam good advice , my brothers 7 port in his buggy is insane now blows most os ninja away ..........

i think my bro just needs to learn a little throttle control but he drives it like he stole it

i also like what people said back a few pages about idle gap to .6- .9 that also makes a big differance when tuning the with a long needle still on the bottom end that was good advice also
