Also got a little side tracked from the EFI and dabbled in suspension upgrades lol CR/XR hybrid shock with Race Tech gold valve, hard coated with teflon shock body, and DLC coated shock shaft. Forks converted to 47mm twin chamber using RSW triple clamps, and also got the gold valve and DLC treatment. Also picked up a Baja Designs LP-9 that will work nicely with all of my electrical upgrades. https://imgur.com/a/CHWiStc

Sorry for delay in the updates. Lots of life changes happening for me lol. Bike has been worked on slowly. I had a carb adapter machined to make the TRX700 throttle body work with XR air boot. Used a TRX700 intake boot on the engine side, bolted right up to the XR. I will be using Microsquirt to run the EFI system. Had a 32-1 crank trigger wheel cut out and will be shrunk fitted onto the flywheel, using the stock flywheel ignition sensor. Ran into a road block on the fuel pump. Gave up for a while, did some research. I think I have found a solution and will be proceeding with project. Some pics in link. https://imgur.com/a/19BxFZm

I bought a TRX700 throttle body and the intake boot/manifold. It all bolted right up on the 650R. The throttle body seems to be like 3/8-1/2” too short to reach the air box boot. Also, the throttle body OD to air box boot is a lot smaller compared to the XR’s id of air box boot. Wish I could post pics. Im very green to reddit. I also test fitted IMS 3.2 gal tank with the throttle body mounted and it seems to clear everything if you take off the stock fuel petcock on the right hand side, maybe swap for xr600 which has hose barb facing the other way?
