Bantam / Cub Swing-Arm Length

I lengthened mine by 1.5" and it still turns great. I used to feel it wheelied too easily up steel hills and it seems to grip better with the longer arm. Used a scarf cut for strength and inserted a tube for strength - used for 2 years and lots of drop offs/rocky sections and no problems.

Whats a scarf cut ?

Just a cut at an angle, diagonal to the length of the tube (if that makes sense?) - the weakest point will likely be either side of the weld but by cutting it diagonaly the weld is spread along a longer part of the swingarm and therefore the force on the weld is spread.
