bansheesa Posted July 9, 2009 Report Posted July 9, 2009 Hi, Ive been searching on the forum for jetting of a STD stroke CUB 65mm with no success. I am really battling jet the 33mm carbs, and the closest I have come to correct is 160 mains, 52 pilots, cel on center, 1.5 turns. Please if you guys can help me on this one. I have the following: 65mm STD stroke CUB with cleanup, 33mm PWK carbs, Boyesen dual stage reeds, 6" K&N Pods, DMC 916 pipes and I am at sea level. Running gas at 32:1 on belray. Temps from 20-30C Thanks guys Quote
wesw Posted July 10, 2009 Report Posted July 10, 2009 where is the bike acting up at what part of the throttle to me your main seems lil big and talk in f dont know what deg c would be. Quote
bansheesa Posted July 10, 2009 Author Report Posted July 10, 2009 Sorry. 70-85f BTM is sputtering a bit. Usual for a cub, but top power is poor. Mid is just fine. Quote
bansheesa Posted July 12, 2009 Author Report Posted July 12, 2009 Would you suggest a 158 or 155? Quote
J-Madd Posted July 23, 2009 Report Posted July 23, 2009 The pipes are probably hurting the top end. GO up on the mains and see if it runs better. If it runs worse, then go the other way. Do a WOT plug check also. Quote
