JDively910 Posted May 24, 2015 Report Share Posted May 24, 2015 I have a 421 built by k&t performance.. Currently Runs absolutely fantastic.. I have upps on and it really likes them but some times boggs or fumbles around on the bottom(hauls ass on top) would a set of intakes with the built in cross over (k&ts) help the bottom end but not sacrifice the top end .. My bike is really known for the top end..currently I have gone 5.804@103.48 (500ft clay not a good solid hooking track) Quote Link to comment Share on other sites More sharing options...

Nightmare Posted May 24, 2015 Report Share Posted May 24, 2015 Sounds like a jetting issue. 1 Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted May 25, 2015 Report Share Posted May 25, 2015 That intake wont do anything different for you. Tuning like jetting or timing can fix bottomend bogging issues. You dont say whether your bike is on gas or alky but both can bog off the bottom when rich. 1 Quote Link to comment Share on other sites More sharing options...
