390 Or > Clutch Wont Disengage

Hi,
Today, I was working on re-jetting my bike (1980 390 OR) and took it for a spin for about 10 min. Suddenly clutch started to not disengage - There was always drag just like being in first gear and releasing the clutch.
I did ride the bike bunch of times before this and never happened before.

Only difference i would notice is; today was very hot day compare to before. ( 84F ) - Not sure if this would make difference?
Transmission Oil > Honda HP Trans Oil SAE 80W/85W

as an extra;
Is there anyone that has the Owner' Manual for one of the years between 1978-1980 (I only have owner's manual for 390 Auto)
I would like to check basic clutch setup...adjusting cable...etc

Thank you

From Owners Manual:

Thank you !!

Any chance if you have the manual that you can share ? I can provide an email if needed ?

Happy to send electronic copy - it is about a 10 MB file. Send a PM with email.

Hi, I've been checking to see how i can actually send you a PM, but couldnt find a way to do it.
Can you please send a PM so that i can reply ?
Im not sure if its a limitation as a user myself, or if i couldnt find it....

Thank you

Sent a "Start Conversation" - lets see if that works. We'll get this figured out!

I would love to know why i cant see "Start conversation" button - I did ask sent a support question about this subject but never heard back.
I would appreciate if admin would help me and let me know.

Thank you !!
I just checked that menu, but i dont have that option.
Let me know if im missing something here.

I only receive messages, but i cant actually start a conversation.

I think you have to have a few more posts before you can start sending PM's?

Yes, i think so....
