I have a 2008 Cross Bone with a ThunderMax Auto Tuner, Installed. Stage 1 kit with Vance & Hines Short Shots. Bike is as brought apart from changing the oval air filter to an exposed element with a sock on it.

Over the past 5-6 weeks, I have monitored fuel consumption,

All readings are from a full tank.

 

#          230 k’s  Light comes on          Freeway only

 

#          245 k’s   Light comes on          Freeway only. Changed air cover

 

#          256 k’s   Light comes on          City only  

 

#          230 k’s   Light comes on          City and Freeway

 

#          250 k’s   Light comes on          City and Freeway

 

#          230 k’s   Light comes on          City only                      

 

I have filled the tank three times when light come on and still had about 5 litres left in tank. (Roughly 19 litre tank, only need about 14 litres to fill)

 

I understand that riding condition will affect, like weather, head wind etc also loaded bags and how hard I am on the throttle etc.  However, it seems to me that the fuel consumption is high. My Dyna would get easy 300 odd before light comes on and I rode that a lot harder than the Bones. Could be because the Dyna was about 40 kilos lighter.

 

Curious about the figures. Are these about right or does it consume a lot of fuel.

 

Also does anyone know of someone that deals with Thundermax, would like to get the system checked. Bike Pops a lot on some days and some its ok also,  once in a while it will bang on upshift. 

 

Thanks for the replies.

Cheers
