Ok temps have come down a bit and I did a two-up ride last night and worked her over pretty good to test out these new carbs. One change is I did a 50/50 mix of 110 octane leaded fuel with pump 93 octane fuel. Vast improvement from pump gas performance, this bike thinks she’s a queen God forbid it’s should run on average pump fuel. Anyways afternoon solo ride felt good, idled OKish, pulled pretty strong. But am I crazy or is this psychosomatic I think it sounds different and pulls a little bit less. So would 2mm make a difference or can this be a jetting issue that can be adjusted? No pinging pulling out when heated up like before, still a few pops through the carbs and erratic enough “tickover” pulling up to stoplights that I do t trust it to just leave off the throttle. Two-up ride went smooth worked it hard as I could with a passenger. No pings pulling out, no pinging when twisting the grip coming out of the curves. Still pops through the carbs when you “goose it”before letting clutch out at light etc (prob a bad habit I know) my big twin Harley with an S&S two throat carb hated that, liked a smooth roll on throttle. So here’s the list of new questions.
What causes the carb pop
Was pinging issue low octane issue or lean issue
Is the sound and feel really different due to 928’s and not proper 930’s installed
Thanks in advance and yes I’m going to start getting my hands dirty on this bike because this “free warranty work” is starting to cost me a lot of time and money. I can make more money, but not time.
