I put a significant amount of time into the CAD files for both the version that is 20 years old and the one that is 2 years old. The originals were machined out of aluminum and used a Mikuni adapter flange. It was simply not possible to replicate the shape perfectly due to the space constraints to mount the adapter. The airbox had to be modified to move the carb. I started the new intake based off the CAD file of the original. I added in the carb mount. Once all one piece, it allowed another 10mm of length to blend the transition from a circle to a rectangle. It only got me back to the fit of the original. I printed multiple revisions to get the carb fit perfect. I then printed 3 revisions that were mounted to an engine to check fit with the last left installed. With an unmodified airbox connected all the way to the carb, putting a large screwdriver behind the float bowl and twisting caused an audible snap when the carb seated into the intake. I ran that for a year before listing on the website.
With stock shocks, the suspension barely moves. Install a $1000 pair of shocks and that U-joint will break. It will break one of those shocks. It will also very likely rip the U-joint through the ears of the dog bone or the outer stub. So you will not even have an axle to put the more expensive joints in. It doesn't really matter because too many people have had the same attitude. I can't get those joints anymore. I think we have 2 left. I have multiple people, including other vendors asking me to make replacement axles. I would have to sell for $800 each. People will complain about the price and buy used axles for $350. So there is no incentive to make the investment of both time and money.
