#109733 daglassguy (User) Fresh Boarder Posts: 82 Changed pipes change jetting? 3 Years, 9 Months ago   I have a 2001 roadstar. I put Baron Nasty habits (no baffles) BAC, and a barons jet kit. The Bike ran like a scalded cat and I ran a fairly consistent 48 to 52 mpg. I recently changed to vance & hines shortshots staggerd. The bike now seems to be running rich. The plugs show a fairly good burn, but the pipes are black and sooty. My mpg has dropped to 32 to 40 mpg. Should I rejet or will tweeking the needle position solve this?   Logged     The administrator has disabled public write access. #109747 BigBoyinMS (User) I'm satisfied never being satisfied. Platinum Boarder Posts: 1705 Re:Changed pipes change jetting? 3 Years, 9 Months ago   Odd... just changing from open pipes to open pipes shouldn't make that much difference. But I would try adjusting the PMS first.   Logged     2006 Midnight   The administrator has disabled public write access. #109773 daglassguy (User) Fresh Boarder Posts: 82 Re:Changed pipes change jetting? 3 Years, 9 Months ago   The vance and hines pipes do have baffles in them. I just ran out and re-checked to make sure.   Logged     The administrator has disabled public write access. #109777 javawave (User) Over 17235 good days in a row and counting Platinum Boarder Posts: 5710 Re:Changed pipes change jetting? 3 Years, 9 Months ago   You have added some back pressure now. If you had rejetted for pipes with no baffles and now have pipes with more back pressure, you may need to rejet to compensate. I will leave the recommendations to the experts, but yes, in this case I would say you may need too.   Logged     \\\\\\\\\\\\\\\"A mind full of judgment has little room for wisdom\\\\\\\\\\\\\\\"   The administrator has disabled public write access. #109784 daglassguy (User) Fresh Boarder Posts: 82 Re:Changed pipes change jetting? 3 Years, 9 Months ago   Im thinking you are right. Believe this had a 165 main in it originally. When I got the BAC and jet kit, was changed to 170. Hoping for a expert who has had the same thing happen.   Logged     The administrator has disabled public write access. #109787 Musky (User) Platinum Boarder Posts: 15137 Re:Changed pipes change jetting? 3 Years, 9 Months ago   Try setting the PMS using the in / out method.   Logged       The administrator has disabled public write access. #109802 daglassguy (User) Fresh Boarder Posts: 82 Re:Changed pipes change jetting? 3 Years, 9 Months ago   I ordered a barons PMS screw and am waiting for it before putting carb back together. Do you think if I drop the needle a notch that it will help the rich problem?   Logged     The administrator has disabled public write access. #109808 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Changed pipes change jetting? 3 Years, 9 Months ago   You don't know where it running rich so first .... ... do the WOT test.
