gear change lever

so about a month ago I had a low side on my left end. it was very mild with minor road rash on the bike and my left side footrests and gear shift were broken. I replaced the rear set within a week and have yet to fix the cutting out of the engine while trying to get into 1st or 2nd gear...

I've just replaced my fear change lever on my 08 ZX6R Ninja. I took note of the position of the nut on the old one, and then replaced it with the new one. It seems now that I can't select any of the gears. Do I just need to keep tweaking the nut on the lever that tightens it to the push rod?
