Hello my o& Uly was working fine up until today while riding it was spluttering around 3k revs,and above too, was like a loose of power and suddenly it comes and goes making the bike pull and push so i coulden't adjust my body to the power income, any suggestions? i do use premium (98) gas here in spain. If i run the ecmspy it doesen't show any thing, nor does the dash light come on. | ||

That sounds like the front spark plug wire shorting out. If it feels like somebody is turning a switch on and off then it's most likely electrical. If it fades in and out maybe fuel related. | ||

Remove the left side scoop and spray the plugs and wires with soapy water to check for arcing with the engine running. | ||

At what point in the ride does it start to act up? Immediately? After riding for a while? | ||

Simple checks that aren't common failures, but that have been known to fail: 1) Throttle body butterfly (remove aircleaner and inspect) 2) Cam Position Sensor (look at tach when the bike is stuttering and see if its jumping all over the place, or better yet, put an oscilloscope on it). Two easy checks, don't get hung up on those problems though, it could be other things. Those are just two easy checks. | ||

I'm wondering if i got some water on the tank as when i pulled the gas house some liquid came out and i didn't notice the smell of gas. first i left the bike on to heat up the engine, after 1km riding it started, was not to bad but it got worse and worse so i drove back home. | ||

Sounds similar to how my bike acted. Clean/replace your IAT sensor, it's a cheap sensor (at least here in the States). Also, check to make sure your TPS sensor isn't loose. After I replaced the IAT and did a mechanical TPS zeroing in the same night, my bike has been back to normal.

Seems it was a bad battery contact change the position of the screw and seem to run right | ||

Glad it was an easy fix! | ||

After working on making a longer positive battery cable and making sure it was well done, now all seems to work perfect, it seems so simple answer, that i really doubted it was that. |
