Last night I used a dremel, a file, and tap magic to remove 0.315" from the inside chain side of the swing arm because the kx motor is quite a bit wider at the rear mount that the yz motor. Test fitted, and the sprocket looks like its centered pretty good with the rear sprocket. But there should be a slight gap between the swingarm and the engine. So I will remove material to get to .375" total material removal. This is very easy to do, just slightly time consuming.
Now the holdup and the hard part is removing this 0.375" from the bearing pin. I couldn't even scratch that with my fancy file, it is extremely hard material. Ill have to take that to a machine shop to throw on a lathe. I found a bearing online that will replace the 2 bearings that are currently in each side of the swingarm, except of course it is .375" shorter that the 2 oem bearings total width together.
Once the rear mount is sorted out, I can move on to the front mounts. Then figure out what carb I want to run.
As a side note, there is a slight bit of slop on the flywheel. Like its not tight on the crankshaft and it rotates until the key stops it. I don't have a flywheel puller for this yet but if you guys think thats pretty weird Ill have to just pull the flywheel and make sure the key isn't sheared then lap the crank and flywheel to fit more snugly.
Any thoughts or suggestions are appreciated. I don't know what I'm doing here
