It's been a while since I've updated this thread, just got done swapping In a 02 CRF 450 engine. WOW, the older TRX engine Is mild compared to the CRF. This thing Is an ANIMAL now. Lots of things needed to be changed. All the motor mount's, slight air box boot mod. The CRF engine Is alot lighter & fits the frame with lots to spare. The crf engine Is one ass kicken engine. Here's a few pic's.
I had to really lean the CRF forward to keep the sprocket In the correct place. Big mods to the cylinder head also to make It work. It was all worth It, I love the power

The TRX is way detuned compared to the stock CRF450. Bet the front end is super light under throttle.

The trx engine can easily make the same power the crf version can, but there are quite a few differences. Cam, head, piston, and others on the primary. Stock 07 450r's make close to 40 give or take, while the dirtbike is making about 50 give or take. The 450 motor is pretty serious technology in the quad or the bike. The quad is just a bit choked up. Anyone thinks they can get onto a quad.
Either way I totally dig this build. From the first ride on my trx450r the only thing I could think of was "this would be the best trike. ever."...glad to see somebodys doing it!

Yes I could do It, but the time Involved Is kinda crazy. The cylinder head has to be modified big time to make the crf engine fit In a 350x chassis. My buddy that owns the ban saw about passed out when he saw what I did to a perfectly good crf cylinder head
I mentioned before, that I saved all the templates when I built both 450's. So anything Is possable, I guess.

Jason you said you had all the templates from the 450 projects right, well I'm gonna dgaf and start this glorious project. I was wondering if I could (if you don't mind) get written down on paper copys of all the materials you used, all the specs and measurements, and every little detail you used and did so I can make this project perfect as possible, without damaging my frame and other vital parts.
I'm first gonna get a kawasaki tecate so I have something to mob while I'm doing this project, done by the master himself Mr. Halls.

As soon as I get my aluminum frame done, I just might have a modified 350x frame & tripples for sale. I have crazy amounts of time In gussoting the stock frame. If you have a stock frame to compare to, you will see just how much has been done to this one.
The Intake has to be cut off the head & moved over about 1" so the carb will clear the frame on the left side.
I don't have an easy way to resize picture's, so It's easier for me to use photobucket. Sorry for the huge pic's & the need to scroll sideways.
