Jetting time

Post by oneandonly04 » 23 Jul 2007, 11:03

on wednesday i'm going to replace my reeds with the boyesen 633's and clean out the ol' carb on my AR, but it's written in the little booklet that came with the reeds that i should change the pilot and main jets by a few sizes. Is it possible to go to my local Honda shop and he'll have on hand the jets that i need? also what sizes are the standard jets?

This is what ive done to my mk2, with a full RSV pipe, and Aktive reeds, which i think are similar to Boyesens............................

PILOT JET-50----(48 IS STANDARD).
MAIN JET-135----(128 IS STANDARD).

Hope this helps :)

Thanks gwyn. A bit of searching in the modifications part of the site says the stock jets for a AR are:
slow jet 48
main jet 148


so did you just go to your local honda dealer and they had the jets on hand, or did you need to order them in?
