drr 70 jetting

[Abennett]

Looking for a baseline for jetting a 28mm pwk carb.
My sons Drr 70 has a malossi replica top end. And a malossi full stuffer crank. And a proformance pipe on the way. Currently running stock 21mm carb. Looking to put on the 28 on with new pipe. And looking for a little advise on both jets to get us started. Thanks

If woods racing would stick with stock 21 mm big carb will hurt bottom end power we ran that combo last year in gncc good budget combo but keep in mind it won't keep up with rt or two fast no matter what

Local flat tracking. Nothing in that order.

24 may work better to pull thur and off turn a 40/42 pilot 120 -125 main should be agood starting point
