rvf400/nc35 power problems(electrical issue?)

Post by peavey » Tue Jul 05, 2011 6:33 pm

Well,
my nc35 is currently only making 46bhp on the dyno and taking a very long time to make it ,the bike is derestricted, it's running with a full tyga system(jetted to suit), carbs balanced, valve clearances done.The guy in the shop reckons that it's an electrical problem .They have tried 2 other cdi on the bike and it made no difference so that is ruled out. Is there any other possible causes for this or has anyone ever come across this problem before?.

vacume hose and fuel line
reg/rec
battery

Yes these bike are prone to the vacume tube collapsing when they get warm (when the vacume tube is old and worn) and this causes fuel starvation. The bike will tick over fine but when you give some throttle it can struggle. What charge are you getting across the battery?

Does it idle okay?
Is the issue in each gear after a certain amount of revs?
Did you have this issue before the exhaust was fitted and jetted?
