well here is my problem,i just ordered a hmf slip on for my 06 dvx,when i called them they said to run a 145 main jet,2 1/2 turns on the air fuel mixture srew,and to take off my snorkel,well now as i read on i hear from alot of people that the jet sizes that they recommend are 10 times to small,this is where i get confused should i go with hmf says? and if anyone has a 06 z/kfx/dvx with a hmf slip on please out post what jets yuor running,i would only like to change them once not a million times

My friend has an 03 z400 with intake/exhaust hotcams stage I and 13.5:1 weisco piston, yoshi slip on and uni airfilter and we just put in a 152.5 and it seems to run great so i would say you are probably around 140-145
