  • Jetting the carb?

    99 Roadstar for starters...clarification please...I have a question on Jetting the carb...I am going to replace the stock exhaust with a couple of selections I have narrowed down to...lets say I go with Cobra Longshots..do I have to rejet the carb? If I go with slip on's do I have to rejet? No other mods to be done just exhaust...

    Just exhaust replacement only no jetting required but that aint no fun. Go with a cheapy K&N filter that clamps on the carb and rejet. It will open up your bike and be worth the effort. JC

      IMO Cobra slipons are junk and look like shit. I would only buy and use a full exhaust whether new or used. Cobra Slipons don't sound real good and are difficult to seal on the OEM head pipes. They pop on decel and are just generally cheap junk. Before I wasted my money on Cobra slipons I would just stage the OEM mufflers and save the money until I found the sound level and style of exhaust I ultimately wanted.

      As far as jetting you may have to do a PMS adjustment. The screw is on the bottom side of the carb and covered with a brass plug that needs to be drilled out/removed to access it. I can almost guarantee this adjust will need to be made for proper performance with any aftermarket exhaust change.

        Drill the stock exhaust all the way (stage 3) sounds surprisingly deep and good just not loud. I would do this and see how you like it. THEN get a 066v K&N filter ($60) and rejet and get some real full exhausts and be happy. Never would do any slip ons....
