Well, finally got to test my mods against a stock BF 750. When we took off I was actually out front , then just like when I was stock he came up along side and started walking on me , I think I held on a little longer this time though, I know ,I know ,I will never make the GRIZ 660 as fast as the BF But I will make it to hang with it in the short run, I have as set of griz 600 clutch weights, and I will put the stocker tires on and the day will come when we run again, I just like taking the underdog quad and try to make it run with the faster ones , I guess I got that from racing the sleds. That friggin BF flys though.We rode just over 40 mi. and I must have done something right on the jetting cause I am getting great mileage , I had 1/2 a tank left , cant wait to go on a ride long enough to run out and see what I get per tank. I know I could figure it out mathematically but I want to know for sure , real world conditions. How many miles do you get per tank on the 660 GRIZ? [img]i/expressions/face-icon-small-happy.gif[/img]
