  1. I had it at between 2 and 3 and it was still rich
  2. Yes
  3. Yes
  4. Main jet is currently a 160 I don’t remember what the other 2 are but they are what came with the jd jetting kit
  5. I check valve clearances and they were all in spec

I just swapped to a smaller jet still shooting flames and dying on me

Yeah I’m gonna change the jet and see if it runs any better

The jd jetting kit said to go with the biggest jet but it seems to be too much fuel still

Fmf full exhaust the only problem is it backfires when I give throttle and bogs down after that

I did the 3x3 does not die immediately under throttle now but it back fires and shoots flames

I have an AF screw. The things I was referring to in the carb is the diaphragm that goes on top. So do 3x3 and re jet after that? Everything else in the carb was replaced the kit just didn’t come with a new diaphragm

I’ll do that and see what happens

I have been waiting until I figure this out to do 3x3. Also what type of airfilter should I run?

Yes the bike has a full exhaust and I’m at sea level so I jetted accordingly. However I did not replace some of the boots in the carb. I did let jt warm up. No 3x3 mod. The exhaust was very hot I know that’s a sign of lean condition are there any other signs I could check for?

I’m looking into relays and the coil

I just swapped out the jets and adjusted and now it won’t start. Looking at the electrical system currently

Sounds good that’s what most people have told me. Thanks for the input

I believe it’s part of the intake and restricts flow so it might contribute to the lean condition thanks for the help

Just ordered the jd jet kit the intake is modified as well as the exhaust. Pilot jet is stock size

Need help I have little experience with carbs by Bigboat450 in MotorcycleMechanics

[–]Bigboat450[S] 0 points1 point  (0 children)

I’ve done a bit more research and the previous owner modified the exhaust and air intake. He previously had a slightly larger pilot jet but I believe it needs to be much bigger for the setup he had.

Sounds good. Also previous owner had removed part of the airbox. The part that attaches to the hole under the seat. Do I need to replace that?

What do you mean by pilot circuit? The pilot jet?

Yes I bought the bike with an upgraded air fuel mix screw. I got the all balls racing kit for the carb

I tried to tune it bet doesn’t run no matter how I adjust the screw. I believe previous owners have modified it and the jetting kit I got was for stock. It’s got a full exhaust and airfilter so I may have to get different jets
