From my limited knowledge on the subject, I have always been told that you want everything parallel with the ground... bottom of the frame, a arms, swingarm... your ability to work the clutch will also play a big part in it

been thinking about the concept of everything being paralel for a bit. What about when you run tall tires like 79 or 81 ro. The swinger will run uphill to the tire. Would you set up on stands with no tires first?

A -6 degree angle will cure that. That's kinda the standard in a lot of places.

We set the weights up based on different factors. We generally move weight around in 2 lb. - 10 lb. increments in different places on the quad.
 
Here's an example: pulling low 1.30 60's with front brakes on bike. Took the front brakes off bike went to mid 1.40 60's. We placed the weight bar on & went back to low 1.30 60's with no front brakes.
 
The bar is made up to allow adjustment of weight with lead shot. We used a section of black iron pipe threaded on both ends. One end cap is tack welded on, the other is just screwed on to allow shot to be added or removed. There's many different ways to make/use ballast & adding weight in the right places can make the quad quicker.
 
IMO, minimum weight to use without a wheelie bar would be 5lbs. & make it so you could add weight to around 8 lbs.

did you notice any quicker e.t.'s/mph gain with front brakes removed after you got the 60's back in the low .30's?

Lots of good tips so far!

 

We use moveable ballast in all our race vehicles. This is a weight bar we made for the quad. It fastens to the front lower bumper mounts on a stock frame. This is where you want it for your issue. It can be used in other places also.
