    GS550T cutting out

    My 550t I have stage 3jet kit Mac pipe dyna s running strong. But under load accelerating to much throttle and it's like I hi a rev limiter the bike, cuts out then grabs. At first I suspected clutch,no maybe worn springs in timing advance dogs, but could be weak relay for the coil relay mod bike has 13,000 miles

    "My 550t I have stage 3jet kit Mac pipe dyna s running strong. "

    What kind of pods?? Does this "rev limiter" occur at certain rpm or just under hard acceleration?

    have you noticed the thread right above yours?

                  So above 5000 rpms, it starts cutting out... Does the tachometer show this effect? Rpms drop, then recover?
                  How's your petcock- you sure it's delivering enough fuel? Have you tried running it in "PR" spot?

                    OP, you are going to have to use straight English with capitalization and punctuation if you expect to get much help here. Proofreading your posts for grammar and typos before you post them would help, too.

                      Geez guys, cut him slack. He has upgraded to the dyna, got the stage 3,with decent pods, 4 into 1, so he's not trying to cut corners here -
