horrid fuel effeciency!
 

My 3TB XT400 has a serious problem....it's got a drinking problem! I get awful fuel effeciency! 10km/1lt ......a 15lt tank.....i start worrying about running dry when i have about 120km - 130km on the clock.....WHAT COULD CAUSE THIS!

Surely it should get atleast 200km out of a tank.....and it's a 400 dammit!

Please any help would be great!
