White Knuckle GP-1 System

[RX-1ND]

Anybody running this exhaust above 6,000 ft with the ECP filter kit and if you are what jetting are you running? I know that when you run the stock exhaust with the ECP filter kit above 6,000 ft you are to run the 160 jet, but when you purchase the GP-1 from White Knuckle they recomend when you are running a stock airbox to jet from 135 to 140, so I was wondering if that consept applied to when you are running the ECP filters + the GP-1.

My friend and I are both running 165 with the ECP. My friend has the White Knuckle QC-1 and I have the Bender.

We both ride from 7,000 to 12,000. Checked our plugs, they could be a tad rich but not worried for a four stroker.

Also I would highly recommend getting your carbs synced ( two minute job ), all our sleds were way off----------thanks again for Freddies advice.

Running 160's on mine and no plugs look great.
