Have you checked the needle on the throttle slide to see what clip it’s on? I would  try to move the clip down one or two spots closer to the bottom. 

And when the engine is running if you can turn the air /fuel screw all the way in the engine should shut down. If not then that screw is worn and needs replacement. The engine should immediately respond to any adjustments on that screw. 

If not then it’s def going to need a new jet kit.  I was looking on eBay and Amazon. It has to be an oem or better brand. It was $27 bucks. It has to have the air fuel screw as well and all jets.    

I would order one and take the carb completely apart and soak it in a good bath for a day or two.   Then blow every port out on that cab with some good air pressure.   

Reassemble and set the air/fuel screw at 2 full turns from a snug position. 

That would be my way to go about it.

Is the float height in spec? It's most certainly a lean condition whether it's a jet still stopped up or float isnt allowing enough fuel in the bowl to keep jets wet. 

[Frank Angerano]

That could be happening but what I’m referring to is the needle in the carb on the throttle. See the pic. The lower you move the clip the more fuel it allows. 

[Frank Angerano]

You could double check that the float is set properly as well making sure your not set to high.

Any luck ? 

[Chris2018]

I can't see the picture you tried to send. And I'm I just going to order a kit for it just to avoid all the B's, it wouldn't hurt to get it anyways. I didn't get into the carb aga n yet but I'm f it's the needle in thinking if and it has a little c clip in it there is only one spot for it to go. Not saying I looked at it real close either. I'm starting to break it back down see what else needs to be fixed and clean it up at Sam time. Here are a few pictures.

Would have have any idea where this goes it was in the box of parts and for the life of me I can't remember. I havent messed with these things since I was a kid and I didn't take it apart to be able to remember where it goes. I thought it was the chain roller but it's on there

[Chris2018]

Will a oe kit work? 

[Chris2018]

Sorry

[Chris2018]

Ok so oe will work. Any idea what that part is for I sent you a picture of? It was in the box of parts and I can't figure it out

Miss type

[Frank Angerano]

I’m sorry I don’t know what you mean. Can you explain better ? I also didn’t get a picture 

That rubber piece with the bolt ? 

That looks like the chain roller bushing.  Take a look at the pic.

[Chris2018]

That's what it looks like but there is one on it and I asked the people and they said there wasn't any extra parts lol

Man that bike looks nice

Not going to lie deffeinetly going to steal some of your paint scheme. They painted my foot ped and sh** green I like how you're are black

[Chris2018]

I noticed you pained the chain too. How did you get just the outside? Or did you paint the outside then tape it and repaint the inside to

[Frank Angerano]

Feel free to take as much of the paint scheme as you like.  I like the black because it gets the most wear and tear down there with the feet.   A bright color would show everything.   

 

That chain was $20 bucks on eBay.

So I finally was able to get back out to the garage and work a little more I just replaced the top end gaskets and am a little confused about setting the timing. First the flywheel ended up moving while removing the head. All I had to do was continue the rotation and set it back at top dead center correct? And when setting the timing do you line it up with the "T" on the flywheel it is it the notch. It got me a little confused bc this is the first four-stroke I have worked on.

[Frank Angerano]

Yes the T needs to be on the mark on the flywheel cover.  
 

 

[Frank Angerano]

[Chris2018]

Thanks. And don't ask me how I completely missed that in the manual. But it was  originally lined up with just the notch befor the T. Is there a chance the velves are bent. Or is that not far enough off to cause damage

 

And the top part of the dot on the exhaust cam is lined up with the top of the head correct while the inlet cam bottom part of the dot is lined up with the top of the head correct?

[Frank Angerano]

Correct and should have no damage to the valves.  

[MarkinAR]

Ha, that's interesting. An old Honda manual I have said to line it up using the hash mark right by the T. Wonder if I mis timed the last yamaha i rebuilt then....

[Chris2018]

Thansk. I appreciate all the help that had been given. As stated before this is my first real tare down and rebuild.

[Chris2018]

Now I'm a little confused when reading these feeler gauges. The manual says to set velves between 20 and 24 mm. Is this the correct gauge to use. The extra numbers confuse me. This is 20mm?

[Frank Angerano]

No worries brother that’s what Quadcrazy is here for!   How did it work out ?

[Frank Angerano]

.020 is 20 mm.  So base it from there. 

[Chris2018]

So to make sure I'm clear as I'm getting ready to do this. My feeler gauge that says,.    .508                                                .020mm , is the correct one?

[Frank Angerano]

That is the correct gauge.  

[Freezeman]

On your feeler gauge the .020 is the Inch measurement which is equal to .508 mm

Frank is correct that it is the right gauge, yet he is mistaken to say .020 is 20mm

Try to remember that 1 mm is = to .03937 inch

[Chris2018]

Its been confusing the hell out of me bc I seen someplace that they should be set at .008 also

And in the manual is says 20-24mm so when I was looking at the gauge I was thinking the .20 was in inches and not mm and I don't know just confused the hell out of me

[Chris2018]

I'm trying to make sure I got this right. The 3 degrees messes me up some. Here is two picture of the way I have the timing set. I have the 1st and 43rd tooth marked along with the dots on the cams. 

[Frank Angerano]

That is correct @Freezeman thank you for clarifying that.  @Chris2018 that looks correct with the timing. When you have the cam chain tensioner tight rotate the engine without the spark plug installed and make sure it cycles nice and smooth. You can use your hand and slowly push the kick starter down nice and easy.  Feel for any hits or resistance  and check that the marks line up on the sprockets as you rotate the engine and the piston hits TDC again.
