What did I screw up?
Just finished a major service and on my ride yesterday noticed a significant hesitation when starting from a stop. The harder I accelerated, the worse it was even to the point of getting a small "pop" backfire a couple of times. Stalled it once when not paying enough attention. Generally clutch out at about 3K RPM when starting off.
Haven't cut the brown wire, so have experienced the hesitation in the hot months and this is similar, but more pronounced and it was only in the mid 50s yesterday on the ride, and have not experienced that hesitation previously except when the temps are high.
So, I've come up with some suspects, but not sure they are the right ones or how I could figure out which one to chase without tearing it apart and doing the service all over again.
Bad fuel - did I just get a bad batch of fuel in the tank?
Bad fuel filter - I actually took the tank off and had the dealer install the fuel filter, so would think they did it right, but perhaps not, or the filter itself is bad.
I'm pretty sure I got all the hoses hooked up correctly, but perhaps not.
I have not overfilled it, but perhaps gas got in the canister, have not performed the canisterectomy. Would this be a symptom?
Spark plugs. The backfire makes me think suspect a timing or spark issue, but at idle or revving on the side stand, don't hear anything abnormal, only hesitation seems to be under load.
Oh collective wisdom, where do I start?
