Hey guys

I need to pull my DG pipe off the bike and return to stock, too loud for my riding area.

Does anyone know what type of jets are used on the 86 PJ flat slide carb? Is it slotted or hex? My local dealer claims they can't easily get them, so I was going to order, but I see both types in the sizes I need.

Also, I was going to do what the service docs state, 145 main and 42. I have a K&N, everything else stock. Is that a good place to start? Thanks a lot!
