I run an adjustable cam, adjustable ignition is soon to come.
Why would you need a six piston rear caliper to slow you down? I can lock up the rear end easily at any speed.
Why isn't the front disk as important, they are rotational mass.
I read in motorcycle consumer news that 1 pound of centrifical weight and three pounds of dead weight were equal.

I personally would want to lose the the rear brake. You want to lose as much of the driven rotational mass as possible. You can lose more weight by dropping the front brakes but that weight isn't as important. I heard that every pound that is saved from the rotaional mass is worth 10 pounds of dead weight off the vehicle. That might be an exaggeration though.

Now this is what I have missed seeing on here!!!!!!!

Chromoly frame purpose built -30 lbs
Lightened crank aprox 5 lbs off recip
Flywheel lightened, charging system removed 3-5 lbs off recip and no generating drag
Total loss electrical system would necessitate battery charging between rounds though.
Yah I don't have much to do either.

I'm not positive but I believe that since the rear disc is rotational mass that is driven throught the powertrain, it is more crucial. I don't know, maybe the rotational mass on the front is as important. I'm glad you brought it up...hmmm

it might have picked up a few thousands of a second. and a 1/4 of a mph. i'm at a point with my bike it is hard to get it faster, a stock bike would more than likely pick up. don't think in tenths of a second. a tenth is very hard to get. 650manica went from running all shocks to struts and picked up .030 (5.20-5.17)seconds in 300 feet. i think that the struts is the best way to get better times. after he and i didn't pick up very much from the struts i run my shocks at the sand drags now.
on a 2 stroke weight really seems to help. i think it is because of my power and torque that the weights don't seem to effect it.
i have let bigger riders than me drive it and they think that weight doesn't effect it either. to go fast is in the motor more than the weight of the bike. if you lost 100lbs you would be able to tell a difference in 300 feet. but i don't not know of a 100 pounds that can be deleted from the bike
