+1. I use one of these on the cap of my Safari tank. It even works fine with a Giant Loop Fandango tank bag.

41 mpg seems low, are you bouncing off the rev limiter? What year, how many miles? Stock gearing (15/42)?

Just for reference:
You're getting 41 mpg (108 / 2.6 gal = 41), so you can go 32 miles on reserve (41 x .8 = 32). Are you feelin' lucky?

fwiw: I had the stock tank for 43k miles and I used this system for most of them. My mileage is better than yours, but I live, ride and am jetted for 6k + feet. I also treat the bike gently ().
Yeah I had done the mpg math, and thought it was low. I am not extremely hard on the bike. I do ride around town a lot. Not stop and go, but around town traffic. I am at 200 ft above sea level (so sea level for all practical purposes). The bike is 100% stock with 1046 miles on it.

Thank you for the info on the reserve. The furthest I had pushed it so farwad 11 miles. And that had me nervous. Just because I worry a lot.

Valves needed any adjustment?
Gearing: Stock, although I switch over to 14 tooth CS when going off road.
Oil change interval: 3,000 to 4,000 miles
Oil choice: synthetic or motorcycle blend no particular brand
At each valves check, they have been within specifications

I do ride just about everyday which I think is important for the longevity of any vehicle because it keeps the universal corrosive solvent (water) from accumulating and damaging components.

I also ride mosting on payment in heavy traffic with speeds from 10 to 90 on a typical day. Lots of lane splitting.

With stock tank, I generally look to fill up at 100 miles and hit reserve by 120 miles.

Stock tank and carb set up. Hit reserve around 128 miles. 2012 model. Figure I'm good for another 30 on reserve but don't try to push it. Looking for gas once I hit 115 or so.

Acerbis Grey Tank is on the shopping list.

With the Safari I usually get about 350 miles before I hit the reserves.

I guess I'm not to far off then. This has been a process to figure (mpg, ect ) because I usually fill up my gas cans at one of the few stations that sell ethanol free gas and then fill up my bike from the gas cans.

With my stock tank I'd hit reserve from 125-140 miles depending on how much fun I was having. I put the Acerbis tank on there and now I'm all cocky, just fill that bad boy up with a swimming pool of gas and ride all day. I don't even think about gas until I hit 200. Used to have to get gas every place I could out here, now I drive by gas stations and flip them off.

Carb Work



What the float adjustment looks like. Float is perfectly parallel but the measurement is not what I have seen it posted to be.

New emulsion tube
New needle, clip set in the middle
new slide and new guide

Carb completely rebuilt
Valves set with the Procycle feeler gauges
Two brothers pipe
91 octane fuel
1000' AST

157.5 Mikuni Main
Fuel screw 2.5 turns out

Results;

1/4 to WOT great. Good response up to rev limiter
occasional backfire separate from decel pop
1/8 to 1/4 throttle, lots of surge
Idle is nice after the bike gets warm. I'll put a tach on it to set the idle later in the week.

Dont worry about the popping on decel.

Try another half turn out with the fuel screw.

It seems like everyone is getting a few more miles out of the tank then me. I don't think I'm that heavy on the throttle. The bike runs well but does have the smallest of a shudder during acceleration. I just thought it was the crappy stock jetting. Maybe I should head back to the dealership and have them give it a once over. Might as well take full advantage of that 12 month warranty right? I guess one day I will end up getting an aftermarket tank. Even though I REALLY don't want to.
