This was already discussed on your other "sponsored" thread and you chose to ignore it rather than respond. This was my post.....also backed up by Bluemax and others.
MaximumSled weighed an 07 Mach Z. Wet weight including a FULL tank of fuel was 596 lbs. Without the fuel it weighed 529.6 lbs. This sled did not have electric start.
Where are you coming up with 650 lbs?
Relax Driggs........Let's have some fun with this once and for all, I'm curious as well......My buddy Mark has a 'totally stock 07 MachZ' that he'll hopefully allow us to use as a test mule. When it's convenient, I'll take my (4) scales over, fill his sled up to the proper wet weight and check it. As you know, my race 2007 MachZ was 579 lbs with 1 gal of fuel in the cell, let's see what his is........I'm going to go out on a big limb here and say 600+ lbs!!!! I'll report back ASAP.
