i'm in the process of working on a set of 1992 F2 carburators off a bike i bought used. in the bowl chamber there are different sets of jets, but my question is about the one that is removed by a flat screwdriver that threads onto a jet holder, which is removed with a 7mm socket. i have 2 different pairs of jets (the ones that sit on the jet holder) of two different sizes. carbs 1 and 4 had size 102 installed and carbs 2 and 3 had size 135 installed. are these in any way correct sizes and in the right carb? the other type of jet that threads directly onto the carb body is a size 38s for all 4 carbs.The needles installed are all J6CF. I also have a set of J6CA and a pair of J5FA and a pair of J5FB. The J6CA is in a zip lock bag labled "was in factory jet kit box" and the J5FA and J5FB is in another zip lock bag labled "taken out of F2 carbs".

I don't know which ones are OEM honda and which are aftermarket.

Here's what the bike's set up is.....full aftermarket micron system and K&N air filter. As far as I can tell there have been no motor modications. There's nothing else about it that i can see different from stock. This is not a california or overseas model and I do not live in high altitudes.

any help on the matter is greatly appreciated.

oh does anyone know which year it was when honda changed the rear rim size for the f2/f3? what size was the original and what did it change to? was is 4.5 to 5.0?

i forgot to click the alert me through emal box so can you send an email to rc51_sp2@hotmail.com
thanks.

 

from what I could find out on my part fiche is that your slow Jets should all be a 38(QTY 4) and your main jets could be either a 132(QTY 4) or 135(QTY 4). I didn't give me any information except a part number for the needle set (16012-MV9-670). Their shouldn't be any miss matching of needles or jet sizes. Hope this helps.

 

Might be different for 4-strokes but I know they mismatch snowmobiles for a "fat" cylinder.

 

I don't know why you would want to do that but stock is calling for all the same jet sizes for each carb

 

4-strokes may be different like I said.

 

I understand that I just don't understand the concept of a "fat cylinder." I'd love to know though for future reference.

 

i talked to my dealer today and we couldn't find the jet size info, but he told me to check factory site and k&n's site. he said that the info i'm looking for may be there. thanks guys. if anyone else has info please post.
