AFR
Posted: Thu Apr 14, 2011 7:27 pm
Hi All, i have been mucking about with a O2 sensor on my new build motor;rapido classic, 71mm wiseco kdx piston, 60mm crank, LTH reedvalve, 24 mikuni tm through airbox and Ron Moss avanti exhaust.
carb setup with 20 pilot 4DH7 bottom clip and 195 main, i am getting AFR ratio of around 12-12.5 from 1/4 to 3/4 throttle and 11.5 at WOT , in 4th gear (4.7 ratio) i run out of revs @6300 am i too rich at WOT
wondered if any of the dyno boys who use this forum have any input on what i should be shooting for ? i can datalog AFR and RPM if thats a help
Cheers
Paul
