This view shows the tank with plastic and resonator removed.
This shows the chain case cover that I received from Black Diamond Xtreme for my project. This is a billet aluminum piece weighing 1.7# compared to the 4.7# of the magnesium cover and tank. As you can see it will include the mounting area for the speedometer pick up unit. My molded plastic oil tank will be mounted high on the cover...hmm better get a hold of Seth at Trail Tanks for this project. Also you will notice there will adequate room for my tunnel exit exhaust.
4.7# for the oem cover/tank and 1.7# for the billet aluminum. The production piece will also be magnesium and should bring the final weight closer to 1#.
