I am replacing all of the jets and valve seat in my carb...Does this pilot air jet 2 exist? I am looking at the schematic in two different service manuals...in one it is numbered 6 in the other 18...it shows that it is located somewhat below or next to the choke origin in the throttle body...Is it the small deep hole underneath it behind the flat bracket??????? Manual says that standard pilot air jet 1 is #75 and standard pilot air jet 2 is #90. The only variations on my carb from stock are: Stock Mine Jet needle DTM-3 OBDTM Pilot Jet #45 #48 Starter Jet 1 #65 #60 I have an aftermarket header and FMF e series pipe (12 disks) Has be VERY tough to start....so I am replacing all jets (with current sizes), needle, valve seat, gaskets, a c pump diaphragm, cleaning. Previous owner said bike ran well with before. I also changed the exhaust can to a auto decompression with correct .20 valve clearance as Hot Cams instructed...Intake clearances were in spec. Any insight appreciated. Thanks so much.
