wild HP 300 rebuild

[case-racing]

Well guys it's time to rebuild my much loved wild HP300 quad, so far i've rolled it, squashed 2 mufflers and twisted the balance shaft, after much reading i put the motor back together without the balance shaft which cracked all my engine mounts and learn't me a few lessons on vibration. so my question to you guys is while my majour rebuild is going on what mods should i do.

Vibrations are crazy without balance shaft, haha,

A larger radiator is a must, if you want to run fast!

Have you fixed the upper a-arms, to correct the castor, and reducing rider arms fadigue?

What all is involved in the castor fix?

[2stroker]

Cut the upper a-arms and install uniball bearings. Know you can adjusting the nuts to correct the castor angle to normal values, lets say 2 to 4 degrees. Original setup has about 20 degrees!

I will send you a picture of my quad if you want.
