Horrible Gas Mileage

[platinumnj]

Hey All, I recently put on the following upgrades to my bike:

• BAZZAZ PERFORMANCE Z-BOMB TIMING RETARD CALIBRATOR
• BMC RACE FILTER
• POWER COMMANDER V- WITH BROCKS STREET MAP
• DROPPED 1 TOOTH ON FRONT SPROCKET
• BROCKS ALIENHEAD FULL EXHAUST

I can only get about 120 miles on a tank of gas using 93 octane. Is the bike just running really lean? and I need to get it custom tuned on the dyno? If so let me know...

Thanks,

Also Is the Z Bomb Timing Retard hurting my bike at all, and my performance?

You've dropped a tooth and are running different maps, so I'm not surprised that your fuel economy has changed.

BTW, if you're using lots of fuel, isn't that called "running rich"? (Serious question.)

that was the first thing popped out to me too (running lean).lol....I put the Brocks Alienhead on with a PCIII. I get about 160-175 miles to a tank. I'm still running the factory filter though.

My vote is to let Adam come over and do what he did to my Xtre

I will be taking the Zbomb off tonight, and will let you guys know what happens.

Drop the Z-Bomb

i stay around 36 mpg wich goes for 160 to 180 miles per tank. i'd lose the z bomb and see how that affects it. good luck

I'd make sure the map and your new full exhaust are working together and are suited for one another.

At least that's my best guess.

my own bike is doing about 20 mpg
its got a k&n,custom exhaust system,air box mod,pair valve removed,power commander
and got it tuned up last week.
killing me in juice
its over 6.50 euro a gallon over here.
o the joys of it

Gen1 or Gen2?

Gen1 does much better on 87 octane
