is it like a dune/play port job??? Get some CPI in frame drags with the appr carb jetting. Maybe upgrade to a bigger carb. Possible get a 4mil stroker. Do the timing +4 but with the adj plate not the key so you can really dial it in. Coolhead yes, 21cc domes maybe??? Not good with any of that stuff.lol. Other than that sounds good. You shoul get a decent power gain and have a nice little rocket. What suspension are you going to run??? Ext swinger, axel. You doing this for sand, mx, drag what???
