I recently built myself a carb sync tool. I read about how to sync the 3cylinder carbs on the 4 strokes. But i was wondering how you sync the carbs on the 4cyl engines. Wondering if i am doing it right or not. Thank you.

That is with a bought manometer.I have the home made carb sync tool. So this doesnt help me since i cant hook all 4 carbs up at once. Only 2 at a time.

Found this tip online in a bike forum.

Interesting and makes sense. You find the reference carb (the one that can't be adjusted, check the linkage), then match the other 3 to the reference carb. However, as you tune each pair it throws the others off so its a PITA with many reps to get it right. If you have a homemade per the liquid in tube closed system, suggest you add two more to your board and save major time. I don't see anyway around it. Someone may have a rubix cube magic rule but I suspect doing two at a time, will drive you bonkers.
