hey all!
I was just wondering as I am about to take out my stripped pilot screw. Is there an alternate carburetor to the CV?

If you're getting really bad gas mileage, I'd have to assume it's worse than a jet.

Do ;you still have the stock petcock?

1300 rpm after adjusting to 900 (I'm assuming it was cold) is normal after it's hot but can be an indication of a bad idle mixture tune.

I'd clean the carb and check every adjustment when you put it back together.

That sounds like a sticky slide.  It is vacuum operated and the bike will run really lean any time it sticks when you open the throttle.  

I had a few intermittent issues with mine.  I thought it was jetting until it stuck shifting from 4th to 5th.  I lost all power and rolled to a stop and then it just magically fixed itself.  Several days later I was leaving for work and the bike lost power shifting to second and it wouldn't go more than 10-15 mph.

My slide was showing some wear so I replaced it and it's been perfect ever since.   They aren't cheap so consider a careful cleaning and inspection first.

So I totally can concur with the sticky slide. However my dumb self realized that I had put a smaller fuel filter in there that was supposed to be “high flow“. So this begs the question, external in-line fuel filter or no? I did away with the fuel filter and took it for a ride no problems. I had my key in there for scale. I also did not ever have a problem with the larger filter.

My theory is this:  Petcock not withstanding, a stock fuel system/jetting should always provide you with decent performance.  Air filters and exhaust will have some effect on jetting but it should still perform decent enough to be reliable.  

If it doesn't run at least okay with the stock stuff in there, then you have a problem.  Go back to stock or some setting that was working okay and figure out what the problem is.  Too many people try to jet away problems instead of fixing the problems and then jet for performance.

I appreciate it. That being said, I have a Dyna exhaust, I’ve done the spacer mod in the carburetor, raptor petcock. I think Main is a 155. I think I’m gonna go ahead and pull it tomorrow evening and clean it anyway. I guess I have to buy three or four jets and see what runs best? Because my gas mileage is really falling off here lately but it’s running real strong. And I think the whole reason I added the filter is because the guy I got it from I’d let it sit for literally a couple years lots of rust inside the tank. I put muriatic acid and BBs in it and tried to clean it out as best I could. So I put that filter in as extra back up. Plus she looks too good not to run right!

I have a Dyna and all the jetting mods too.   Airbox is stock. 

The guy I got it from had a 155 main and a 55 pilot in there.  It sounded cool but ran like a turd and go around 30-35 mpg.

My jetting is a 45 or 47.5 pilot and a 147.5 main IRCC.  I get around 50 mph and I'm not a small person.  I ride in temps ranging from the mid 30's up to the high 90's and the elevation ranges between 500-1100' around here.   The bike is still a little too rich when it gets up into the 90's and a tiny bit lean below 45.  It's happiest in the 50-80 degree range.

The Dyna doesn't require anything special.  The 155 is probably too much.  Probably start with a 150/50 combo and go from there.  But make sure the the jets are fully seated.  The seat for the needle is not loose and has it's o-ring.  Make sure the slide is clean and not worn.   And the diaphragm is seated properly.
