This is highly possible.
Chris, Does the vacuum nipple on the intake have a hose connected to it?

I’ll have to look at the pod air filter. There really isn’t anywhere to have an air leak besides the joint between the air filter and the carb as it’s mounted directly to it. I know I have it tightened down very tight to the carb with the worm gears. Hmm

Ok, we may be onto something because you know the two hoses that run into the factory air box? I just left them there. One is the crankcase breather and I figured it’s fine to vent into the old air box, but I don’t know what the other does nor did I do anything with them.

Yes, stock pilot jet. I did the basic idle mixture procedure as how I learned it online. Adjust the rpm idle screw a bit low so you can hear variances one the idle speed, and then adjust the idle mixture screw richer and richer until the idle reaches its peak speed and then go slightly more lean until it starts to slow again, then go right to that point it’s right at its fastest. Then adjust the rpm screw to where you want it.

The odd thing here is, the rpm just kept getting faster as I turned the idle mixture screw clockwise until I could no longer turn it. It seemed odd, but at the time also idled really well. It’s only now hanging and then dropping idle after 4-5 seconds at idle, once warm.

The air leak Bogieboy is speaking of will be where the carb attaches to the intake. You don't want to over tighten it. remove the carb and check that the o-ring isn't damaged. I usually smear a little grease on it to help it seal.

The nipple i'm talking about is on the intake between the carb and engine. If it is uncapped or no hose connected to it then it will run like it's real lean. Fast idle and idle hangs. But from what i'm reading you just need to open up the idle mixture some to give it more fuel.

Ok, thank you Jerry. I’ll look at the intake and play with the idle mixture screw after work. Well, I’m actually running the 100 miles round trip after work to visit the girlfriend, but I’ll check both Wednesday.

I’m excited to log some miles with the bar risers and new sprocket.

I'm sure your going to enjoy your ride a lot more with the 36 tooth sprocket. I have to hit the interstate today for about 60 miles to go look at a new project. I get to joy ride on the bike while at work. lol Oh well somebody has to do it. Might as well be me.

I just ran the 50 miles to the girlfriend’s house. The bike is much more pleasant to ride with the sprocket change. I also had no problem pulling hills at 60-70 mph. It helps that the bike’s peak torque is at 5500 rpm, or 55 mph, and the bike’s peak hp is at 7000 rpm, or 70 mph. It’s perfect as the bike pulls great in this range and it’s the exact range of speeds I run.

My next project is to drop the rear shock out of the bike so I can adjust it to be more firm. I can’t get any tool on the adjustment at the base of it with it installed on the bike. Anyone have any suggestions?

I also want to buy a tank bag and tail bag to improve my carrying capacity when I travel on the bike. I may even buy some matching saddlebags.

Glad the sprocket is working out for you.

Hang the bike from the rafters and remove the shock will probably be the best way.

I use my tail bag daily. It's just big enough to store a rain suit and few extra small items. I stuck a HF generator battery in it on Friday.

I ordered a really nice Chase Harper tail bag and a Chase Harper magnetic tank bag, but in the meantime this is how I roll when I need to carry a lot.

Also, I’m at about 190 miles on this tank of gas with the new sprocket and at about half a tank of fuel. This mileage calculation is going to be better than I expected.

I can’t get a picture to show up straight to save my life. iPhone 10 and the damn camera already broke so I’m having to use the selfie camera and I think that’s what is messing up the pics.

:edit: Yep, that’s much better. Sigh

Man you got her loaded up pretty good. The best fuel mileage I've gotten so far was just over 81mpg. 362 miles on the tank. 4 days riding to work on the current and still over 3/4 left in tank. But only driving 59 to 60 mph. My worst was around 65mpg.

The fuel mileage on this bike is incredible. My last tank of gas with the stock sprockets, spilling a whole carb worth of fuel, and lots of WOT acceleration yielded 64mpg. I bet I see 75 this tank. Much better than I expected.

New luggage test fit. Chase Harper bags.

Oh, and I hit 72.2 mpg on the last tank of gas with the new sprocket. 302 miles on 4.18 gallons of gas. Very happy with that.
