#66332 Tealw1 (User) Senior Boarder Posts: 254 Afterfire 8 Months, 3 Weeks ago   I've had my 07 Roadie for exactly a week and had a couple of questions for the experts. I was just reading Bomberchamps thread that answered my noisey engine question, but is it supposed to afterfire or backfire everytime I turn it off? When I turn it off there is a loud ziinnnggg at the front of the engine then it pops out the pipe. Is that normal? Do I need to adjust something that the dealer misadjusted out of the crate? I'm thinking that I may need to, because I can't seem to get over 37 mpg. I have 528 miles on it and have gone from 32 mpg to 37 mpg.   Logged     CAGUAMA-Big and Cool   The administrator has disabled public write access. #66333 Curt (User) Never to old to ride! Platinum Boarder Posts: 3024 Re:Afterfire 8 Months, 3 Weeks ago   The engine is still tight and the zing noise it the starter doing a back run which is normal so don't sweat it. The other is the piston kicking back on the compression stroke after you've turn it off and that to is normal. Everything will settle down after you get a few K on it.   Logged     Last Edit: 2008/03/04 11:29 By Curt.   Black Ice is Shinny, Black Ice is Deadly, Ya Wanna Ride My BlackIce?   The administrator has disabled public write access. #66334 SobaCracka (User) It's best to eat crow while fresh. Platinum Boarder Posts: 1518 Re:Afterfire 8 Months, 3 Weeks ago   Teal, There have been posts before about that Ziiiiing sound (I hear it, too, on occasion). The more techy folks will step in, but if I remember right, that has something to do with the starter backing off its spring. I get the occasional pop, too, but if I let her idle drop after stopping before shutting down, I get nothing.   Logged     Last Edit: 2008/03/04 14:15 By SobaCracka.   Earl in Catonsville, MD   The administrator has disabled public write access. #66355 Tealw1 (User) Senior Boarder Posts: 254 Re:Afterfire 8 Months, 3 Weeks ago   Thanks for the soothing and comforting news. This is by far the best bike I have ever owned. Big step up from the Virago 1100.   Logged     CAGUAMA-Big and Cool   The administrator has disabled public write access. #66379 SobaCracka (User) It's best to eat crow while fresh. Platinum Boarder Posts: 1518 Re:Afterfire 8 Months, 3 Weeks ago   No problem. When I first got my '05, I took it to the dealership 3 times because I thought the engine was coming apart inside, especially at the higher end of the gears. The Clinic guys settled me right down and helped me identify the various rumbles and grumbles and fix a few of the rattles and clinks. I find that when I smile hard enough, the tight facial muscles close off my ear canals, and I don't hear as much noise.   Logged     Last Edit: 2008/03/05 22:45 By SobaCracka.   Earl in Catonsville, MD   The administrator has disabled public write access. #66618 Clifford (User) Expert Boarder Posts: 489 Re:Afterfire 8 Months, 2 Weeks ago   The starter works through a "ratchet" mechanism called a SPRAGUE clutch. When you push the button the starter turns the engine. when the engine is running the starter is not disengaged, but the clutch prevents the engine from turning the starter. If one of the cylinders is on the compression stroke, and as it shuts down the compression causes it to flip backwards momentarily then the backwards moving engine turns the starter backwards and that is the noise thet you hear. If one of the plugs fires just as the engine stops that is the pop that you hear. Neither one should happen all the time; but when it does happen it is normal.

Not sure if there is some other way to explain it. My 78 xs1100 will do it to if you turn the key off and on a couple of times,and never caused any problems.   Logged     The administrator has disabled public write access.
