Yo! First post here. I've got a 2000 Sixxer with about 18,500 miles on it, and had it dyno'ed a few months ago. I live in Denver (high altitude), and the only fuel system change I have made is the addition of a K&N filter to try and get a little more oxygen in there.
The dyno run showed two very distinct stumbles, one around 6-7k rpm, and the other around 12k rpm. The data just flattened out through there, which I found concerning. Overall, the power was lower than I would like to see (around 91hp), and those stumbles are worrying.
Does anyone have any thoughts as to what is causing these stumbles? I am sure there is a good reason related to the jetting and the airflow, but I haven't done any tinkering with that ever. Any advice would be appreciated! Thanks
Unlike women, my motorcycle likes a little gas.
