As stated not sure what to run on k&t 421 and a 521.. Never ran sand only made 2 passesin 300ft.. Ran 3.8 @ 87.82 on the k&t 421 on VP race fuel.. Any tips would help I'm running a h.o.d chassis and I weigh 170lbs... Any gearing and tire size would be appreciated for both

video would help. Depends on the tire youre running and if youre just smoking the tires all over the place. I run or will be running 14 paddle extremes with 72 RO on my 421.

also start with 14/41 to start. I believe that is correct. Then tune from there. Take a video and upload it here and people will be able to help you dial it in completely.

This was on hard packed clay/dirt also... I also have a 5.804 @ 101.35 backed up with a 5.86 @ 102 on the same bike.(500ft @ bbdr in pa).little bit out of gear. Just want a shot to run with the big guns next year. Maybe Kentucky if I get it fast enough
