Fmfs or very close to them.
I went through this with mine.
I found dyno tuned settings (3-5-.5-8-4-4) on high fives site and tried them, they were too rich off the bottom and caused stumbling.
I leaned out the yellow mode one step at a time untill it ran good off the bottom.
The bike would also cut out while cruising down the road, setting the yellow/blue mode to 6 fixed that, this is a common issue.
I ended up at 3-3-.5-8-6-4
fmf recommends 3-2-.5-8-4-4
Start with one of those they should be fairly close then test and tune it to your likeing.
