The long ones are for FCR and some Harley Carbs. The OEM short style ones are for CV/CVK models (your 250r).
I did testing on substituting long and short Keihin main jets many years ago, and I don't actually recall it making any difference on the Dyno. But obviously the FCR style is twice as long as your OEM main jet, so this is wrong. The bottom line is that you should get the correct style (short) main jets for the OEM 250r CV carbs. |
