Non Honda ATV

I bought the service manual before I pulled the motor out, but during the re-assembly process I broke the electrical connector off the solenoid assembly B and the solenoid assembly linear so I bought a new ones and installed them. Is there any adjustments that need to be made to the solenoid assembly linear (Picture)?  I also removed the valve body and cleaned it out. Could the clutches be sticking and need to be replacd? 

Ok, that actually makes sense.  You have two clutches in that machine (DCT, Dual Clutch Transmission).   One is for 1,3,5, and the other is for reverse, 2, 4   So, given that you started having this problem when you disassembled and reassembled the engine, I would guess you didn't get something back together right on the 2nd clutch.   That said, first I'd do some testing and make sure that the solenoid on the front of the engine is working properly.  The DCT's run off of oil pressure to engage the clutches.   Go to the toolbar at the top of the page, click on the "service manuals" button, and download the factory service manual for your machine.  We don't have one for a DCT Rubicon, but for your engine troubleshooting the one for the 2014-2019 420 DCT should work fine.   Look in section 13, which will show you how the system operates, and then you'll have to try to figure out what exactly isn't like it should be.   The DCT's are complicated, and a PITA to work on, which is why I got rid of the wife's DCT Rancher when she decided she liked my 05 Rubicon better.    

Been a minute since a update but got all new billet internals flywheel a flattop piston  and new carb    waiting on the cam to get there then it’s time to put it back in the bike

Hi @Kyle9076 I would say it's the capacitor for the pull start -- just unplug it -- tape it up good and plug it back together

there should be a sticker somewhere on the frame under the front fender, it will read something like trx420fm-with maybe some letters after the fm. the round connector in your first pic is normally wired into the main harness, if this is the case ?, you will have to buy a whole wire harness to solvet this issue.
