That’s a clean looking carb - is that how it looked when you opened it? Your needle is OEM. You can improve throttle response by replacing that white spacer with a #40 washer. This is well documented in the performance faq. The pilot jet (52.5) is a good size. You might find better performance with a 148 or 150 main, you won’t know until you try.

If you want, for now just swap out the white spacer with the #40 washer. I think you’ll find that the bike runs a lot better.

If it's starving you need to make sure the diaphragm on the slide is seated or you may need to replace the slide.  This is critical before looking into jetting.

The bike should run reasonable well with stock jetting. Maybe not perfect depending on the mods the PO has done, but decent enough that you are talking purely performance jetting.  If you are talking "this thing hardly goes" then you have other problems that need to be resolved before getting in too deep with jetting.

That’s how the carb looked when I opened it. Maybe it was cleaned just recently before I bought it?

I’ll sand down the original washer a bit and clean the diaphragm with soap and water.

Put it all back in and see how it runs. I guess I’ll have to adjust the idle mix screw once everything is back on.

As Ohio said, check the diaphragm for cracks and tears. Any damage and it needs to be replaced.

Before I purchase the bike I ordered a carb rebuild kit.
This is it.
Maybe I could use some parts from that?

extra parts is always good to have.
as far as the jets go, don't trust them as you don't know what year or from where they were intended for.
yes, eu and usa have different metering.

Does my float seem pretty high? See pic

This is from another thread:

Float level is 1.06 to 1.114" for all models.

It's out of spec. Bend the tab to get it closer to an inch and you should be good to go.

Your main jet and pilot jet sizes agree with the as delivered specification.

Your picture of the float level measurement shows that you are measuring from the gasket to the bottom of the float.  That gasket should not be in there for the float level measurement.  Remove the gasket, then do the measurement again.

The float level spec you provided does not agree with the factory specification.  The factory spec is 1.100" to 1.140".

I suggest you follow Gary's advice and use #4 washers rather than sand down the white plastic washer/spacer.  That way, if you are unhappy with the results you still have a good white plastic spacer to reinstall.  With the #4 washers, you can add or subtract to set the needle exactly where you want it.  So you have the latitude to try one washer, two washers, three washers, or the white plastic spacer/washer.  

The stock plastic washer is .113" thick, each #4 washer is about .030" thick (depending on manufacturer).  So one single #4 washer will yield the richest mid-range.  Two washers will lean out the mid-range a bit, three washers will lean it out a bit more, and the stock plastic washer will set it to the factory (waaay too lean) setting.

Thanks for the pics.  Very helpful.  Good luck.

 You should hold the carb in you hand sideways with the float hanging down below the valve so it just touches, the float level is from the flange to the top of the float, But doesn't include the gasket.
