Not that it cant be done with a two guage setup but i recently did a sync with a motion pro and it was pretty simple since all 4 are being synced at the same time, might be worth getting one if your planning on keeping your bike for a few seasons

 

I didn't realize the F3 carb was different from an F2 but wasn't sure either way.
I have an F3 carb sitting in the garage but didn't want to remove the velocity stacks etc.

I need to play around with it one day I guess, but I'm tired of messing with carbs lately.

 

I'm currently in the garage trying to get the carbs synced. I'm comparing #3 to #4 right now, and I'm not getting any reading from #4.

I tried flooding each carb with carb cleaner. I was able to stall the bike by flooding #1, #2 and #3. But I was not able to stall the bike by flooding #4.

What does this mean? What should I do next?

Also, I can see gas spraying into #4, more so than the others. I can hardly see it in the others.

 

If you aren't getting a reading, then I'd say that that it's not connected properly.

 

I just pulled the throttle, and I'm getting a very very faint reading. I double checked the lines and they're connected properly.

Does this have to do with a float being stuck or something?

 

If a float was stuck, you'd know it. If it were stuck open, fuel would flood the carb. If it were stuck closed, that cylinder wouldn't run right.
