New to this forum, so please don't jump all over me. lol Have the sons CBR600F2 1993. Hasn't been started in 13 Years and tearing it down. He has #122 main jets now, but I was wonding what the stock main jets were when the cycle was bought new? Have a couple of packs of mets, but not sure which ones were the stock ones. He dosen't remember. It only has 2500 miles on it, and was used for racing. Would appreciate any information on this. It will probably be a year project for me.

 

I believe that the main jets on the f2 stock is #132. and your slow jet is #38, but you usually don't change that.

 

Thanks Brian. It had 122 in it and I found the pack that was labeled DY122, and it has the K135 which I think are the original. Thanks again

 

No prob. I was going to put up #135, because I think thats also the other jet that the f2s have, but i didn't want to overwhelm you with to much info. Im pretty sure they will work fine.
