  • Trouble with my TL1000R - please advise!!

    On Saturday, I had a 7,500 mile service performed on my 2K2 TL1000R at my local service shop/dealership. When I rode the bike home from the dealership, everything operated properly – clutch, brakes, throttle, handling, etc.

    On my way home I rode down the interstate as I normally do, cruising at 5,000-7,000rpm, in fourth and fifth gear. I exited the interstate, stopped at a stop sign, turned left from my stop, accelerated briskly down the next mile or two of road, up to ~9,000-10,000rpm, then gradually slowed down for another stop, down shifting, clutching fully, then downshifting again, down to first gear at a stop.

    As I slowed to about 25-30mph, with the clutch pulled in, I heard a pronounced “pop” from behind me to my left. I noticed no change in the engine, the engine speed, felt no vibration, etc. I thought maybe my bike had backfired, but it could have been traffic around me. I tried to think nothing of it and to forget it.

    This morning, I headed to work on the interstate again. Again, I rode normally, cruising at 5,000-7,000rpm in fourth and fifth gear, with a short run up to about 9,000-10,000rpm. I traveled ~8miles down the interstate before exiting. Upon, exiting and downshifting through the gears at ~45mph, I heard another pronounced “pop” from behind me to my left. Again, I noticed no change in the operation of the bike, but now I know the sound is coming from my bike.

    As soon as the service department where I had my bike’s 7,500 mile service performed opened this morning, I arranged to have the bike looked at. I wasn’t able to talk to the tech personally, but only through a receptionist. Through her, he says he doesn’t know what could have changed to cause the bike to backfire but he will have a look at the bike. He said that he didn’t adjust anything on the bike that could cause a backfire.

    The 7,500 mile service for a TL1000R includes:

    Inspecting the air cleaner,
    Replacing the sparkplugs,
    Inspecting the fuel hose,
    Replacing the engine oil,
    Inspecting the engine idle speed,
    Inspecting the throttle cable play,
    Synchronizing the throttle valves,*
    Inspecting the evaporative emission control system,*
    Inspecting the PAIR valve (air supply) system,*
    Inspecting the clutch hose,
    Inspecting the clutch fluid,
    Inspecting the radiator hose,
    Inspecting the drive chain,
    Inspecting the brakes,
    Inspecting the brake fluid,
    Inspecting the tires,
    Inspecting the steering,
    Inspecting the front fork,
    Inspecting the rear suspension,
    Tightening the exhaust pipe and muffler bolts and nuts,
    And, tightening the Chassis bolts and nuts.

    My bike is bone-stock, always dealer serviced, and in the last ~7,660 miles of riding, the bike has never behaved like this before. My bike is not a CA model, so I don't believe the above services with the * would be performed, though.

    So, what are your thoughts, and/or advice??

      As far as I understand it...the TL's are quite prone to backfiring (especially mine...blue flames about a foot out of the can when I decelerate through the 4500 rpm range)

        Stock TL's should not be doing all that backfiring, however, every now and then maybe.

          Make sure the TPS is right on and remove the pair valves ASAP, backfires should be gone. What gears are you downshifting through when it happens? 3-2 or

            I have no idea if they adjusted the TPS. I'll have to call them...

            Yeah, it seems to have backfired around my 3rd to 2nd downshift, no slower, no faster.

              check your exhaust gaskets arent blowing. part no6 on drawing is most common. you'll see it by your rear suspension.
              if it does not have good seal then it will suck air in on deceleration and cause a backfire.

              good luck

                The tech said that he didn't have to adjust the TPS - I guess that means it's set properly?

                I'll check my exhaust gasket when I get the bike home tonight.

                  i too just had the 7500 mi service done (on my tls) last saturday, but the shop i went to didnt add in a bonus "popping"

                  mine isnt really stock anymore though, so i have had some popping on hard deceleration for quite awhile.

                  to make sure the service was done properly, i took it out sunday and ran 315 miles of twisties at a somewhat "brisk" pace

                  she performed like a charm

                    You most likely have an exhaust leak that is causing the backfires, I have one and mine does it on occasion too. Its fun when it happens next to a car, scares the shit out of the driver

                      I love the "popping".

                      Acctually, mine was funny today. When it did a BIG backfire it felt like the bike hoped forward a bit, almost like it did an extra puls in the cylinders.
                      Hmm, afterburner

                      Never done that before. Wierd.

                        Maybe this is just my bike telling me that it wants an aftermarket exhaust now? Hmm.

                            sounds like a plan if you like the popping
