I used 87 when this started. A mechanic in another forum recommended 91 because when there's ethanol in the fuel your 87 is less. I pulled the plug, it's running lean. Cap has been adjusted half way, 1/4 as some have suggested, no help. Only runs good with half choke. Another guy had the same problem, the Honda dealer couldn't figure it out? I'll pull cover off to check inline fuel filter. We can't be down a week or two. This is new and the benefit with Amazon I can get two Yamahas within two days. Honda isn't want it use to be across the board imo. I've owned over 12+ Moto's and cars power equipment in the past is why I went back. There's too many issues with the fuel/carbs with Honda. Not as many with Yamaha, not as sensitive with poor fuel as we have in California (placerville)
Thanks all
