i would like your opioion on this i can't decide what one i want a 38mm pwk air striker or a 39mm pwk wich is better for all around riding because they are the same price
thanks

 

For standard bore, I would recommend the 35mm A/S
For larger bores, the 38mm A/S, possibly taper-bored would be the best way to go


ps: This, and many other questions are answered at

take a look at the new psi big air carbs,they also just came out with genisis big bore kits with vep valves for the 250r.their carbs have a triangle design so they are like a 32mm at low throttle openings and a 40mm when wide open.they have two sizes.price is around 500.00 but you dont have to jet them,they have full external adjustment. psiperformance.com
