Monster 1200S Fuelling
I have a monster 1200S with CF termigoni slip-ons and ECU sports map year is 2015.
I have always noticed to varying extents that fueling is on off or "stutter" like, as if fuel is being taken away then given away then given back, surging almost, it happens only when i hold the throttle steady at about 4800 RPM, it's there in all gears but most noticeable in 1st gear. It is not noticeable if you simply accelerate through this rev range but sometimes if I am going slow in traffic it's annoying. It doesn't seem to occur at any other point in the rev range. I remember this being the case pretty much from day one, having this inconsistent or not smooth fueling at this rev range. Of course it is much less noticeable in higher gears but it is there. Due to a myriad of other problems I had with the bike I had the ecu replaced, throttle assemblies and such and this never made any difference. I just wonder if anyone notices this on theirs. I notice the effect is amplified if the bike is really hot, which is why I am posting this I was riding bout a week ago and it was really hot and it was doing this in a really pronounced fashion, heat aside it is consistently there to a lesser degree...Any thoughts appreciated.
