Use your GPS speed Blister. I would trust it before a chinese speedo. Mine GPS at 42 and some change. As for the weight differences. Besides the obvious of motor position, battery placement etc, is your shocks. Crank the preload up on a shock and the weights will change. _________________

Blister,
just an observation from someone who doesn't know much. When I was looking at buying our first cart, a local guy that sells Twisters had a 05 150 and a 05 250, and I can tell you without any doubt that the 250 was a lot faster than the 150 out of the box. These were un modded carts, so this is the best comparison I have to give. So I think that Twister may have some things figured out that not everyone else does yet. But then again, I think they used basically the same sized frame, which is tight for me, on both carts.
Just food for thought. _________________ 2 Twister 150's

The difference there mobuggy is when Blister and I raced our 250s against our 150s, the 150s were modified to the gills. This is why the 250s got smoked. BUT and thats a big BUT, TJ Powersports have figured stuff out...they build proven quality buggies. IMO they stuck with the slightly modded rear end of the 150 frame because it was a good size for a 250 motor. Most of the 250s frames are built like they need atleast a 400cc motor. So yea I would agree that TJ does there homework and if there buggy sucked, because they do test the crap out of them before they hit market...they wouldn't sell them. _________________ ~~~~~~~~~~~~~

Well, I finally received my MOC paper yesterday (after purchase in January) for my Dune 150, and it lists the weight at 617 lbs. I DO have 2 old bathroom scales and will weigh it myslef and report back when I have a chance.

I weighted my challenger 250 single seat with bathroom scales to come up with the weights, full tank of gas, oversized battery, oversized tires, estimated (on the heavy side) about 5# of reinforcing steel added.
left front-86
right front-112
left rear-189
right rear-175
total-562
Someday I'll get it to scale to get a accurate weight.

I can see where you add all the weight readings of the scales and the total is right but as far as being acurate for that corner the elevation of the scales need to be the same. Put a level across and set the tire pressure. I would adjust the front springs until the front wheels had a more even weight distribution because two wheels putting more down force diagonally will make it want to rock back and forth diagonally around the corners similar to removing a wheel at opposate corners. The weight of the motor should not be as big a factor on the front with the swing arm setup because it doesn't pivot so the frame shouldn't lean except for a small amount for tire deflection. Independent systems would be different. If you have less down force in your left front when you make a hard right the left front will sink and you will be prone to roll over. We set our suspensions an even number of spaces as if the frames were perfect. Just my input I am sorry for carrying on and I don't even have a scale to use yet.
