whats the difference?

Ok guys. I bought an HMF slip on, a K & N intake. I have gotten those two items on, now its time for jetting. I bought 152-160 jets off of jets r us. The slip on came with a jet, it is a 165 with a K in front of it. The jets I got from jets r us dont have a K in front of them. Are those Keihin or DJ? I would like to get this thing jetted up and running, but I dont know if my smaller jets are from Keihin.

I am at 200-500 ft, 40-90 degree weather. Lid on. I was thinking of doing the 155 main with a 42 pilot.

Thanks!

Yes, the "K" in front means Keihin. DynoJet jets are round and much shorter. For your mods, I would probably go with a 150 or 152 main and a 40 pilot, needle in the stock position.

hmm, the ones i bought arent round. They look exactly like the Keihin one that I got with the slip on. Should I assume they are just knock offs made by jets r us?

yes they are Keihin knock offs. at the shop we stock RD jets, same as keihin.
