High Altitude Benders Jetting

[intoodeep]

Anybody running the Bender pipes, what do you guys run for setup from mains all the way to fuel screw settings? I've been playin around with my Variflo and I forget what Bender recommends for baseline jetting. I ride 5000-8000 feet. I use the Variflo to lean down when goin up high or on warmer days, but would like to know what you guys do. Also heard that Varilfo leans down the entire circuit?? Is that true??

Currently setup as follows: 140s across, needles in 3rd setting washers over and under, 55 pilots, .7 air jet, fuel screws 2.5 turns out.

I have the reed spacers, airbox mod, and one head gasket layer removed.

Thanks for all and any help.

I would reccomend that you call Mtn Performance they are great to work with and will give you any info you need to make your Yamaha haul ass.

When i ran benders in my piped (bender) ported 01 700 mm at 7k i ran 141.3 mains, 60 pilots, fuel screws out 2 turns, needles in stock position. The tempaflow & variflow will lean out everything including the pilots.
