If you are getting 49-50MPG... you are *NOT* rich. The think you have to look at is if is smokes when hammering it or accelerating, the accelerator pump is to blame... and isn't a bad thing. But you can reduce it's duration and time can be scaled back.

49-50MPG is very good mileage... getting more all the time is a lean motor. I some time get 55MPG, but as low as 33MPG, depending on how, where and when I ride.

Smelling fumes, don't worry... like someone else said, it is just the unburnt fuel you get from combustion... and cars use catalytics and air pumps to take care of that issue.

I have to disagree……seems these bikes run even when we screw them up. Dialing in after messing with them is the good read you speak of. Rear to read “I won’t run or start”

I may have been running sea foam when I did that run. Cant remember. My bike always runs better on that stuff. The inside of my carb shines like new money lol. Would be cool to stick a spark plug in the exhaust and see what happens.

That is what the AIS did, kinda. It pumped fresh air, into the exhaust chamber so that the super heated unburned fuel, would combust as it exited the cylinder. That's why when you still have the AIS on the bike, and change out the exhaust for aftermarket, it pops on decel. It's the unburned fuel going bang. Same principal with a bad exhaust leak at the flanges, or a muffler joint.
If the bike is getting at least 42 to 45 mpg under normal conditions, and mid thirties when your driving like a throttle hog, your good.
Based on your mileage, and the bike starting normally with cold starts, I think your good. Usually, if the float is too high, you'll see it with the cold start(not needing the enricher), and decreased mileage. Odo's dry set method can be a bit of a stinker when it comes to application. That's why the double check with the yammie method is always a good idea, when in doubt.
As Dave mentioned, don't run the enricher any longer then needed. Mine is always off within a mile, in temps in the 60's and 70's. Yes, it may not run just dandy yet, but it runs well enough to not need the enricher anymore.

Roger that. Been in the fifties here in the mornings. I usually let the bike idle for 5 minutes with the enricher half way in while I put my gear on in the morning.

You know I have been sitting here read so many posts on carbs that my eyes are crossed. I have a 99 with big air kit and short shots. Bought the bike used and have no idea if it was jetted with the install and if so if it is set up correctly. I have what I would say is too heavy a sooty situation with sooty settling on my rear brake mounting bracket area. I have know that the manifold is cracked all over and a new one coming in four days to install. I posted the question of how to solve my problems earlier this week and got some great suggestions such as manifold switch. But I have had some backfiring's and some other issues. But I guess one question I have is how can I tell if the jetting was changed with the Barron's filter once I pull the carb for the manifold install? And if so how to tell the jet size that is there? Also if anyone is running short shots do they have the same soot issue showing up on the rear brake bracket and caliper like I do?

With your intake and exhaust, I would put money on the bike being rejetted.

On a 99,
The stock pilot, is a 35(it'll be stamped on the side, hard to see).
The stock main, is a 165(It'll have a square in a square with an "R" stamped on the top along with the size)
The stock needle, will have a single grove, with a plastic spacer and washer/shim under the clip.
As stock, the PMS screw, will have a brass plug on top of it.

To see whats in the carb, read the rejetting threads on the Tech Articles pages, and you'll see what to look for. Before you put the bowl back on, make a note about whats in the carb, and post here. Somebody will help you with any changes, or opinions.
What is your current mileage?
Have you looked at your plugs lately?
Has the AIS been removed from the motor?

Backfiring can be an exhaust leak, as well as a vacuum leak. If you haven't pulled the exhaust to check the condition of the donut gaskets at the heads, you could do that. If they have a leak, you'll see carbon all the way across the face, instead of nice clean copper.

Regarding the soot, If it is splatters, it is the condensate in the pipes turning black with carbon, blowing out and splattering on the bike parts.

Yeah ais is long gone. The rear soot is just solid cover on everything that I have to remove with brush and cleaner. Hate it. Will pull the exhaust to check gaskets as well. The engine bogs down now when warm as well so I am chasing multiple ghosts at this point.

Supposed to get the manifold Tuesday so hopefully can resolve all of this then. It ran just fine for two years and plugs changed end of last year. Had iridiums but the seemed to not last as the electrodes were just a nub after that one season of lite miles. Running high output coils and new plug wires for two years with no problems. Switched to NGK plugs and will check those when switching manifolds.

Are you sure it's soot, and not the brake pad material? It'll make a mess of my whitewalls.
