Is there a suspention upgrade for the pw80? My son is bottoming it out on jumps. Or should I just not let him jump the 80?

well, it's not quite made for jumping.
Check the PW 80 Questions thread.

Page 28 (post 278) is the front suspension upgrade, still working on the rear.

Smacaroni (or anyone else that has a picture or two!!), please may you post a picture or two of the position where to drill for the top rear shock mount.
I would love to get just a little more height for my daughter so that the bike doesn't quite feel so small.

Oh, yeah, I get absent minded sometimes.


The reason I drilled this in this position is so it could be drilled again above that point for a slightly lower seat height, if needed. I'm guessing most people just drill a new hole straight back. The left side of the photo is the front, the original hole is also towards the front. I forget what I size I used, either 5/16", 11/32" or 3/8". Stock size is 11mm, IIRC.

That is almost exactly where I drilled my daughters bike last night.
The worrying part was where you drill thru just the edge of two layers of material. I was worried the drill might skew off slightly and then not line up all the way true, but I got there quite easily in the end...
Thanks again for the pictures. The US$25 Extender + shipping to where I live is just not worth the costs.
A Jeep brake rotor gives the stand a perfect height to lean on - without it the bike almost topples on it's stand. (I'll get to extending the leg at another time.)
Amazing how much just 1" difference will make to a total picture and outcome!!

Obviously it's too late now, but I drilled the whole way through both sides with a 1/8" bit. Then, I moved up a size or two and drilled one side, then switched over to the other. This way if it does walk, it should walk in a nearly uniform pattern.
The stepped-steel won't affect the rigidity, since the single layer part is in the area of the least stress.
