Sudden sputtering

mine seems to do the same thing of late, post what you find out,

My bike did that like it was starve ing for air or fuel sputering and missing mine was ECU .I think I posted some thing about it over a year ago Mabey longer

Two things.. 1) been thru a lot of dust lately? they IMO need washing more often than advised.. if not then:
2) Sputtering at low revs like below 2k? get tuneboy out & add 3-5% fuel in the cells sub 10% throttle /sub 2k revs. see if that smooths it out.
Filters surprisingly suck quite a lot more air at low revs too, & the Rocket runs smoother with a bit more fuel down there.
3) ( yes I know I said 2... que the Monty Python gags) check the clamps on a) the filters onto the throttle bodies ( no leaks etc) & the lower clamps going to the engine inlets. wiggle the fuel rail, is it nice & solid, nothing comming loose? no flapping around when you rev the engine? if it's not right, then that's usually those lower clamps.

I suspect 2) will work. did for me.

Cool:grin: nice when a fix is so simple:bed:

glad to hear you got it sorted.
