Thanks Jason, Ed

can you post pics of how you had to modify the trx sub frame and a descripion?

[Jason Hall]

The subframe I used was from a 05 TRX, that was bent. I cut the weld loose on the rear tube that holds the two sides together. That was the only part that was bent. I then used the exhaust to hold It In place while I made the mounts. I just made some flat plates, then sliced the square tube Installed the plates where I wanted them. Then I made mounting tabs and welded those to the crf frame. Once the mounting tabs were welded on I tacked the plates to the subrame. Then pulled It all off and finish welded everything. Once all that was done, I moved the front seat mounts out so the seat would mount just like the quad. I did cut about 3" off the mounting side of the subframe, then sliced It & welded the plate's on.

Here's a few pic's.

Edoggy, I will get you up some video this weekend

Cool, Thanks

I thought I saw an old video somewhere of you riding....can't seem to find it. Or maybe it was somebody else.

[Jason Hall]

Here's a couple short video's. Nothing at all special, but It's something. Our practice MX track was a washout, I will get some better video once we can get out there. My 11 year old Is on the 88 250R.

Awsome! Jr. is gonna be passing you soon by the looks of things. Must be exciting to watch your boys progress with their riding.

[Jason Hall]

BigGreenMachine, Jr Is a little bit nutty LOL, but he Is so much fun to watch. It's out of control when my 2 oldest boys get racin around our small yard. Here's a couple pics of Jacob up north on the 85cc 3 wheeler. The pic's are blurry, but he Is getting real good no matter what he ride's, dirtbike 3 wheeler, or quad. Honestly, I would park my bike just to watch my boys LOL. It Is AWESOME to be able to watch them get better

from the pictures it doesnt appear that you used the seals for the front swing arm mount, is this correct and any issues so far? also whats that extra tab that you have welded on the lower left side of the frame below the swing arm mount? awsome project

[Jason Hall]

Audioworks04, I did not use the origional dust seals on the outside of the swingarm. I bought 2 extra seals that Honda uses to seal the Inside of the steel collar, I then Installed those to seal the outside of the steel collar. I used the stock trx thruss washer on the outside with hardened washers to keep the steel thruss washer from rubbing the aluminum frame. So there are seals sealing the needle bearings on both sides. I hope I explained that good enough to understand. I have had 0 Issue's with this setup. I did the same thing with my 350x/450 and ran that bike hard for a couple years with no Issue's either.

The Tab you are refering to Is where the stock CRF footpegs were mounted. It Is a raised flat boss casted Into the frame, I welded the bolt hole shut.
