I just bought a 1985 yamaha moto 4 200 cc the voltage regulator was bad but it ran till the battery died I charged the battery which is only 2 years but if wont turn over I replaced the regulator and still wont turn over just getting a buzzing anx clicking noise from the solenoid relay dong know my next step

I'd check voltage at the battery side of the solenoid, if that is good I'd jump the solenoid to see if it is the problem. I'd also check the battery terminal connections and the ground for it.

How do I do that

You check the voltage at the solenoid with a volt meter and to jump the solenoid use a piece of steel, like a screw driver, to "jump" or connect the battery wire and the starter wire on the solenoid. That is what the solenoid does, you are just doing it manually. You can also use wire, I'd suggest using at least the same gauge as the battery wire.

I tried it and no sparks no nothing just the neutral lite turns off

I un taped the starter and battery wires they were wired pretty loose and sloppy and looks like they tried to sotter together so I'm going to re wire it all today and go from there and I bought a brand new battery so I will try that after

I would take the start switch apart and clean it too. Just scratch the 2 surfaces with emory clothe, or even a knife blade.
I have seen quite a few machines over the years not start simply because the start switch contacts were not clean.
I have even seen several hit and miss starts, and the contacts looked clean, but after scuffing or scratching them, the random or no start problem was gone.
I had a 660 do just that a few months ago.
I'm not saying it's your problem, but it's a simple thing to eliminate.

[/QUOTEit SAS thd battery wire at the terminal was curated now I have gas leaking onto the air box dont know what that means

 

[Tj1985]

Could the carburetor be bad

Gas is leaking in the air box

 

[benmarshal]

Were you able to fix it?

 

[Sixpack577]

Gas is leaking in the air box

Yes, sounds like the float is stuck or the needle and seat need repleced, as either problem would cause the float bowl to overflow, which could leak gas into the airbox.

I ordered a new carb solve all that lol

A Yamaha carburetor may, but a China carb usually causes more problems.

 

[Tj1985]

I put the new carb on now it wont start

 

[Tj1985]

It at least started with the old carb

 

[Sixpack577]

Yep, junk china carb.
Rebuild the factory carburetor.

 

[Tj1985]

Ya I did and it started right up
