I am removing coffmans pipes and aftermarket flame arrestors and putting back to stock. both engines had the carbs rejetted also. wanted to know what the factory jetting is so i can run factory pipe and flame arrestors.

Do you mean an OEM pipe? "Factory Pipe" is a company that makes aftermarket pipes.

OEM Jetting:

MAG 145
PTO 140
Pilot 67.5
HSN 0
LSN 1 +- 1/4

[Dr Honda]

Should have been a 1.5 with a pop-off of 27 to about 39
