Clutch possibly

just purchased a 1980 kz 750 twin and have been working on it for about a week, i got the starter clutch in order, blew out the carbs and the bike runs like a top. I hoped on to take my first ride on the bike kicked it into first and felt a solid engagement however the bike did not moved. The neutral light turned off however the bike is able to roll as it would if it was in neutral. I order new clutch plate but i was wondering if anyone has had a similar experience, any advice helps.
Thanks

Is the chain attached?

This might sound like a stupid question but I've run across someone who thought they had a transmission problem but all it was was the chain flew off the bike.

Yes the chain is still on the bike, and i did double check.

Yup. Could be that the nut holding the countershaft sprocket on has gone AWOL.
Has the clutch cable been properly adjusted? There is a specific procedure that needs to be followed.
Also, the clutch release mechanism may be installed incorrectly, or it may be completely clogged up with smegma (technical term for chain lube and dirt :laugh: :laugh: :laugh: ).

I believe that nut is tight

+1.

Also confirm the clutch plates aren't missing!

I attempted to adjust the clutch as the manual stated but that didn't solve my problem, I will readjust it when i install the new clutch plates the original plates seemed to be pretty burned up. Im just hoping its a simple adjustment issue and not anything worst.
