Post subject:  Mikuni Reverse Main Jets

I'm looking for the next three sizes of main jets for my H2B (117.5, 120 & 122). Problem is I'm looking for the reverse type and one of my local dealerships only has ones stamped "A-B" not "R" (Don't know what the "A-B" designates. Anyone?). I called Sudco and spoke to someone that confirms that they still stamp them with "R"s but they don't sell them anymore and couldn't provide a place that does. Mikuni's website was no help.

Are these things getting obsolete and hard to find? Or am I not looking in the right places yet? Can someone point me in the right direction?

This is the Mikuni part number for a 117.5 Main Jet N100.604/117.5 Sudco sells them last I knew. Also John from Mid-Atlantic and a bunch of other venders.
Also Niche cycle

Well that looks like what I have. There appears to be no distinction with an "R" designation at the end of the part number or on the jet itself.

Plus another confusing thing is that in the link below, page two lists the entire N100.604 series as a "reverse" jet.

I guess my confusion is the jet is marked "A-B" and not "R".

Thanks for the feedback. Unless someone else contributes some additional info I'm gonna move forward with these jets. I just wanted to make sure I wasn't going down the wrong road with the wrong jets.

OK. Thanks for confirming this for me Ja-Moo. Much appreciated. Sometimes the littlest details can be the toughest to pin down......
