If you have spark ( should be bright blue) on both plugs your ignition is working. All that is left is gas and compression. The left one should be a bit closer to the right psi. Check and see if you tci pickup coil off the cam is set correctly and tests ok.

Yes spark is bright blue, and yeah well the compression has been the same when I first tested it when I first got the bike, how can I test the pickup coil on the side of the cam I'm thinking its something electrical cause I have gas decent compression and spark!

Okay sprayed starting fluid in sparkplug holes and I do get some pop and fire coming out exhuast, this mean I'm prob not getting gas to the cylinder heads?
Sounds like a carb issue. To static time a tci pickup. Turn the fly wheel to the LF mark just before TDC. Then turn the pickup so the dot on the rotor aligns with the magnetic pole that is at 12 o-clock. Make sure you reset your valves after pulling that cover off.

You have to reset the valves after pulling the valve cover off, and it does sound like carb issue

Lol yeah I kinda over reacted on the comment lol, normal gas is getting to the carbs as it was when running.
What are your carb settings/jets. Also could you get a better pic of you bike posted? It looks like you have a lot of paint on it ( grounding issue maybe) and a few wires look to go into the shifter cover
If you have good spark and compression plus gas it should fire.
