stock jetting size
hey i am having a hard time coming up with the stock jetting size. does anyone know it off hand. i was looking at my jets and they are all the same size but i was talking to a honda mechanic and he told me that the inner two carbs should have bigger jets because they will be warmer. does everyone else have different sized jets in the outer carbs compared to the inner carbs or are they all the same like mine. thanks for the help.

RE: stock jetting size
1987 to 1996 stock jetting sizes are as follows:
Main Jet:
1000 H, J 1000 K, L, M, N
UK models 120 128
California Models 120 120
All other US 120 122
Pilot Jet:
UK models 38 40
All other US 35 40
1000 P (onwards)
Main Jet: 122
Pilot Jet:
UK Models 42
US Models 40
To answer your question, All four carbs should have the same jets in them. Changing jets or adding a jet kit is needed when installing an aftermarket exhaust. My 94 has after market exhaust and I run 1 size up but they are all the same.
