[QUOTE="joedrum, post: 139464, member: 98"] well i hate to bust your bubble on this ..but ive got way to much experience to know that blanlket graph table means nothing .... try to get a flow rate with cam not hooked up ... on milder way just change cams ... like changing a jet on a carb it will be entirely different... with all the experience i have with these cams heads and port sizes ...it makes a huge difference ... sheesh 1100 cam shut down flow big time at higher rpm ....and gose flat ...carb wont help that ..but a better cam dose ...because it flows more and it not peaked out .....in general your flow chart has some merit ...but its at the lowest of level and should not be considered something to go on as deciding factor ... but i try to keep things real here ... that flow chart gets way more credit than it can back up with so few numbers to go on ... statements like flow not needed and carb to big is bad ...when neither of these lables are even comes close to the this dft series carb ...statement like this from me slants a different way but is more true... yes if you want to run like stock bike .. then just run on the primary barrel ....but if you want to get everything the motor has hook up the secondary and find the rest of the horses in the oldwing motor ...one that cover all the peaks of all the rpm from 0 to redline ..... :BigGrin: sorry but to me that chart knows nothing of the oldwing motor flow needs ...people who read me posts will get my opinion on such charts :cheeky: :mrgreen: :mrgreen: [/QUOTE]
