Engine stuttering after 6000RPM
I've got a 2012 Versys 650 with 11K that started stuttering when I would accelerate past 6000RPM. I'm don't know what is causing this. I changed the oil and filter, put in new spark plugs and replaced the air filter with a BMC performance filter but still no change in the condition. I thought I might have
gotten bad gasoline and I put in a fuel cleaner additive but that didn't help it any either. Any one have any experience with this problem or suggestions as to what the problem may be?
I'm thinking the engine is choking for gas. Unfortunately, there is no way to clean the filter which is imbedded in the fuel pump in the gas tank. I'm not positive that it's a fuel delivery issue.
Dealer wants a few bucks to diagnose the problem, and I'm afraid I may have to take them up on it. I can't eliminate ignition problems without having new parts like coils or ECU for diagnosis.
Your help and advice, dear forum members, is greatly appreciated.
