#25540 Helmut (User) If you can't be young be immature Expert Boarder Posts: 421 Another backfire question 5 Years ago   Hi Guys/Gals I have an 06 RS that has developed a bit of a pop or backfire when I blip the throttle on a down shift. It will occasionally do it while sitting still and blipping the throttle. The bike has had no mods done to it YET. I have also noticed that when I come to a stop there is a strong smell of exhaust. Any ideas?   Logged       The administrator has disabled public write access. #25545 RoadieFF (Moderator) Moderator Posts: 2594 Re:Another backfire question 5 Years ago   Simple answer for the pop/backfire, don't blip the throttle. The carbs on R*'s don't like blipping. I had to break myself of doing it(still guilty on occasion), wasn't a problem on my HD. No idea on the gas smell, someone else will chime in with ideas I'm sure.   Logged       The administrator has disabled public write access. #25549 Cougar (User) Platinum Boarder Posts: 3210 Re:Another backfire question 5 Years ago   Blipping can cause backfiring....errrrrrr...popping which leaves residual unburnt gas ...thus the smell after you blip and pop and shut her down ....try turning your PMS 1/8th of a turn out till the popping goes away....Coug   Logged       The administrator has disabled public write access. #25563 Helmut (User) If you can't be young be immature Expert Boarder Posts: 421 Re:Another backfire question 5 Years ago   RoadieFF wrote: Simple answer for the pop/backfire, don't blip the throttle.

Or does it not really matter that much?   Logged       The administrator has disabled public write access. #25565 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Another backfire question 5 Years ago   You want to increase the throttle to match the engine speed to the gear but you don't need to blip it. Cougar's right about the PMS. Slight popping on decel (assuming the AIS if off) can be reduced by turning the PMS out a bit.
