Wonder if anyone can shed some light on why the main jet needles are a different
My needles:
2 x J1BP
2 x J1BQ
The Official part numbers for my bike (2000 ST1100AY - Police)
16131-MAJ-R00
&
16191-MAJ-R00
It really does appear that Honda designed it this way.
There is a bit of confusion about whether the pairs are split front vs rear or left vs right, I posted a separate message about that in "ask a tech"

Carb spec:
No Emission Control (i.e. No PAIR system , No charcoal canister, no washer under the needle )
Jets : 125 & 40
