Platinum Boarder Posts: 4337 Re:Need help- back firing all of a sudden 3 Years, 5 Months ago   Congratulations, you are no longer a R* virgin. It won't be long before you are looking for excuses to take her apart again. It feels good to poke around and find the fix.

A friend said it sounds like one cylinder is running rich, but with just one carb I don't see how. checked for exhuast leak,but I cant't really tell. I called Dealership and informed them of my problem, but they won't be open until after the new year before I can bring it back. I will let you know how it turns out.   Logged     The administrator has disabled public write access. #147996 javawave (User) Over 17235 good days in a row and counting Platinum Boarder Posts: 5710 Re:Need help- back firing all of a sudden 3 Years, 5 Months ago   DrBONESLINGer wrote: I just got my 2000 R* back from yamaha recall, never before, but now its backfiring from rear cylnder, changed the plugs, same thing.

Its not un common for one cylinder to run richer than the other. You might run some seafoam through it for a couple of tanks and see if that helps any. YOu might have some carbon build up on the exhaust valves.   Logged     \\\\\\\\\\\\\\\"A mind full of judgment has little room for wisdom\\\\\\\\\\\\\\\"   The administrator has disabled public write access. #148015 DrBONESLINGer (User) Junior Boarder Posts: 167 Re:Need help- back firing all of a sudden 3 Years, 5 Months ago   Roger that Javawave, I already added some yesterday and I hope thats the fix, cuz I got alittle over 50,000 miles on it. thanks, just strange it happened after comeing back from the dealer.   Logged     The administrator has disabled public write access. #148017 fireman922 (User) Chrome won't get ya home, but it will get ya laid. Platinum Boarder Posts: 4337 Re:Need help- back firing all of a sudden 3 Years, 5 Months ago   You might have an air leak at the manifold/head connection on that cylinder.   Logged     Grow Old or Die Trying...   The administrator has disabled public write access. #148020 stinger (User) Hey y'all...watch this! Platinum Boarder Posts: 1397 Re:Need help- back firing all of a sudden 3 Years, 5 Months ago   Could it be a vacuum leak at the intake on the rear cyl.? It's possible the mechanic didn't get the bolts tight or pulled the intake bolts up unevenly. You could try spraying a little carb cleaner around the flange. If it's leaking, the idle sound will change.   Logged     http://s671.photobucket.com/home/jhurdle/index   The administrator has disabled public write access. #148021 stinger (User) Hey y'all...watch this!

The dealer might have left the locking clip off the hose. This will cause the line to pop off and display the symptoms you described. It happened to me when I got mine back from the trans recall dealer fix.   Logged     Sig Pic deleted - larger than 50 KB   The administrator has disabled public write access. #148035 DrBONESLINGer (User) Junior Boarder Posts: 167 Re:Need help- back firing all of a sudden 3 Years, 5 Months ago   OK, I'll check that, I did spot a rubber hose line with some type of metal fitting on one end and a 90 degree bend on the other end that is tie-wrapped to some other hose near the center of the pistons. Neither end is connected,can't tell where it goes, may have always been their and didn't notice.   Logged     The administrator has disabled public write access.
