im looking to upgrade my caburetor because the stock one has the bowl treads stripped and it seems to me that now is the best time to upgrade, i do mostly mx and some trails
mods as follow
kor port and polish
kor head mod
toomey b1 full exhaust
vitos +3 crank
open air box uni filter
14/40 gears
what do you guys recomend me for an upgraded carb, ive been looking in to the pwk but i dont know jet
 
I have a 28mm pwk on my blaster and love it . You can find them under $100 on ebay . Get them off a yz85 or kx 85 dirt bike . You're going to need to get the JJH needle for it . As for jetting...70-80 degree weather and 500 feet of elevation mine is 155 main and 45 pilot 1.5 turns out . And the needle clip on second slot from top . Runs unbelievable . Throttle response is like fuel injection lol .
