  • Bike problems.

    I just went for a short ride down the river (about 2 minutes away), got on my bike to come home, gave it shit and it accelerated slower than a Vespa and really jerky.

    It took me about 30 seconds to rev it up enough to change into 2nd gear, even though it was revving fine in neutral.
    It wouldn't let me past 40kmh all the way home even once I got it up a few gears.

    It's a 2005 VTR 250.
    Any one got any ideas as to what could be wrong?

    Cheers in advance.

      Nope.

      Seems to be something electric but I'm not sure what.

        Got a sidestand switch? It might be shorting or something. Also check the usual, plugs, leads, etc.

        Maybe something wrong with the fuel? Try and tap the fuel bowls of the carbs with a screwdriver handle to see if anything is sticking too.

              LOL



              Anyway... fuel problems would effect power delivery, but electrical problems would better explain the 'really jerky' activity... did the bike recover after standing? have you run it since?

                Aren't they all just as slow as each other?

                I haven't run it since tonight, but it has done it once before about 4 weeks ago.
                I left it for 15 minutes and got back on it and it run fine last time.

                  umm the obious question how much fuel is in it? Where was the fuel tap set? how old of the plugs they do crap themselves every now and then.

                    ah, gotta be electrical then. Does it do it then stop doing it?

                      Well like I said, this is the second time it has done it.

                      It went away after giving my bike a little nap on the side of the road last time.

                      This time it lasted the whole way home and I haven't ridden it since.

                        This sounds familiar, I think it might be a clutch issue.
                        Let me guess... as you accelerate, the revs jump up without you going faster, and it feels like you're repeatedly pulling the clutch in slightly but it doesn't really grip again?

                        When it used to happen to me, it was usually that the little knob on the end of the clutch cable had jumped out of the little actuator and was sitting behind it, therefore keeping it out slightly even when the lever was released. If the cable has too much freeplay it can happen quite easily.

                        So check that the knob is seated properly at the bottom end, check the freeplay and maybe lubricate the cable also.

                        Hope i'm right and this is of some help...

                          Yep, that's exactly what it felt like.

                          I just had a bit of a play around with the clutch and will take it out tomorrow and see how it goes.

                          Cheers for the help.
