My bike has been running pretty good, but not perfect. Yesterday was a little cooler (mid 50's) and when I started my bike (full choke) she warmed up good, but I could smell gas (which makes me think rich, but the choke is on). After a few minutes I went to 1/2 choke and took off. Spit, sputter, cough! She runs fine after she warms up, but last night (again being colder than its been) she started popping on decel(which I thought was gone). To me, it sounds like I'm on the edge of one of my settings. When I set up originally, I was lean and kept adjusting pms until the popping stopped. Do you think I should just add a 1/2 turn or so to the pms or is 4 - 4 1/2 too much and telling me to change something else?

1600, 170 on 4th clip,(spacer under, washer over), #35 pilot, pms 3 1/2

Smelling gas when the choke out is not unusual as you are enriching the circuit quite a bit.

You are correct ..... as the temp drops the bike leans out so you need to richen it up. If the bike runs better after it warms up, it's also a sign that you are probably a bit lean.

Is it quite humid around your area? High humidity means you'll run leaner; high humidity plus cool temps are a more effective at leaning it out.

Usually all you need is to turn the PMS out a bit, but I see you're almost maxed out.

You should verify that you do not have a small leak downside of the carb and that the float level it OK.

Try turning the PMS out 1/2 turn. It should work for the current temps (it is getting warmer as we speak ) but for riding in Oct and Nov you may eventually need to go to a 37.5 pilot. Might be a good idea to pick the jet up just in case.

Also try 2 silver washers under the spacer before changing out the pilot. You'll need to re-adjust the PMS. That may be enought to richen the circuit out without compromising your mileage to much.

Thanks Doc...I'm glad to hear you confirming my assumptions. That must mean I've learned something! Who says you can't teach an old dog new tricks!
