Well the subframe on my prp had seen better days to say the least, it had been wrecked hard a few times, had been bent and cracked and fixed one to many times.
So since Zeb was too busy i decided to just build it myself. In hindsight i would have waited to use the correct tools for the job but i had it in my head that i needed to do it last weekend. It did turn out good and rides SOOOO much better,.
The plan was to #1=lower the seat height 1.5-2" than what it currently was. Ive always had troubles in the corners with this bike and i blamed it on the seat height. #2= change the airbox/intake setup (went with a easier to obtain 400ex setup) #3= mount the airbox better( used 4 tabs with shouldered screws and nyloc nuts) #4 change the hinge design so that IF i was to wreck it agian it wouldnt have any funny business to get bent up in the back.
I used 3/4" and 1/2" .065 wall 4130 chromoly tubing and then threaded pipe adapters with 5/16-24 heim joints for adjustable mounting to get the height just perfect.
Enough talk here is how it turned out
the old
