Hi guys, just orderd 2 IMS tanks from Just Gas Tanks 3.1 gallons,as far as fuel consumption goes first ride on the WR 450 I got 70 km and hit reserve, the next ride was after I had set the carb up as per Nutty Professors specs and you wouldn’t want to know I used 6.2 litres for 127 kms,single track, fire roads etc etc could not fault the bike at all. So when the tank arrives should be good for 200kms or more.:lol:
