what ya talking about willis? ha ha.....
pj not sure what/who your talking about here?
NO carb will be properly jetted out of the box unless your lucky or they prejet it for a specific alt,temp,etc.
if your refering to the pwk's being properly jetted for honda your right- i doubt it. but a great alternative to mikuni if your willing to set them up......
if your talking about them being properly jetted for brit bikes(bsa,tri 650's) they are sold for your wrong....they have a great track record of being very close from the box and we(jrc and dealers) include proper jets to start with for the specific bike you own but in my experience of selling about 50 of them - not one complaint, only raves about how well the bike starts,runs,idles, accelerates etc (guys on britbike.com who have used them all like them also)...i installed one on a wide case 250 duc and i only had to go down a few sizes on the main to make it work good....plus price,parts availability is great also-peronally i have been sold on them...
later,joe
