Gas Mileage?
KXcam22:
Dezracer,
Like Gowen, on medium speed single track I can do a full day on a tank, anywhere from 60 to100 miles, 1st to 4th stuff but too narly for too much WOT. Mine is jetted really nice and crisp, 55p 165main at 1100-6000'. Depending on your elevation and riding type going smaller from the stock 168 makes a nice change in throttle response at 3/4 and up. Cam.

Thanks for the info everyone. I think I'm going to check the float level and adjust it if necessary. Anyone know what the specs are for the float level? It's a 97. The bike runs strong and has great throttle response. I think the jetting is close to where it needs to be, maybe drop a size on the main jet. If that doesn't work than I'll have someone else take a look at it. Thanks :D

Dezracer,
Look in the jetting thread. I put a detail of an easy way to set it using an piece of fuel line. Cam.

Dezracer,
I had a thought last night on possibly why some K5's might get poor mileage. I have run my float both high and low and didn't notice any performance difference. What I did notice with a high float, when riding in gnarly stuff, was the amount of gas that comes out the carb overlfow. With a high float level, my bike would piss out a bit of gas everytime it was not perfectly horizontal (ie, when it's leaned against a tree so you can help your buds climb the hills you waltz up, and even on the ride/climb itself). This could amount to a small but significant amount of gas over the course of a long ride. I think I might test this sometime - set it high and put a beer can on my overflows before a big ride. Whatever you do don't mention this to the EPA or the California guys will have to have a govt. certified float level calibration sticker (more $$) to ride. Cam.

Cam SHHHHHHHHHHHHH dont give them any ideas here in CA. My float level right now is high. If I lean my bike on anything the gas will pour out. So I am guessing you probably found the answer. Oh btw I could not find your post on using the fuel line. I really want to do this. I need to lower my float level just a little.
