What are the Stock jet sizes for a 92 CBR F2? I recently cleaned my carbs for the first time ever and i believe i put some things in the wrong order. If i recall correctly there are two different sizes for the 2 outside and the 2 inside jets. My symptoms are little power on the low end, then takes off like a bat and then no power and then bike chokes out. i have most power between 4-8k range and if i go any higher or lower it boggs. It was to the point i lost so much power in third gear that i was going 25 in it and if i shifted down i lost even more power.

 

Specs I just read say that 92 should have 135s all four carbs or 132s for Calif models. 95 thru 98 bikes had 135s on the outside carbs and 138 on the inside carbs. Your symptoms sound like when my jets came loose inside the float bowls. Pull the bowls and check that your mains are properly tightened. You could be running off of pilot jets only. Mains only kick in about 7 or 8 grand revs.

 

You where exactly right gp! When i opened then up my reaction was, "well then, would you look at that he he he" tightened them up nice and snug and now does she fly. Once thing i did notice though was that some of the jets said 132.5 and some 135. Maybe i am reading this wrong and i have not noticed any blank spot in the higher end of my band so I wont argue it.
