That's currently a work in progress. I was missing one of the O-rings on one of the valve cover bolts so I had to use a make shift one. I think the oil was coming out of there.

I finished everything up! Bike runs great, oil leak gone. Just a couple problems, there is some pretty bad decel popping and the bike is a little muddy pulling through gears 3-5. Low end torque is out of this world. 1/8 throttle and my bike is straight up in the air. I have a 13t sprocket so I'm sure that helps . Any ideas why it's a little muddy mid range? Or how to get rid of the decel popping?

Don't know what to tell you about mid range. I'd look to jetting, but you've done so much at once it's hard to tell where to look. One mod at a time...

Midrange : lift your needle 1 position and retry .
One should really begin tuning the carb fromm the top down : main jet/ full throtle ; needle / 30 -> 70 % throtle ; pilot / up to 30 % ; and then idle .

And bump the shim on the throttle screw up one notch. Bike idles really strong now. I would be careful with letting it sit too long cause the fan kicked on a few times. You can feel the heat coming from the header pipe.

No it's in the third position with the 128 main jet. I might need to try the second position down?
