I haven't had this bike long at all, maybe a month total. It always started fine. I decided to shortin the Yoshi tube, and when I put it back on, the bike started, ran rough then cut out. I'm not sure if shortining the pipe has anything to do with it or not.
If I turn it over, sometimes it sounds like it wants to fire, but no go.
The red light to the left of my nuetral light is on, any ideas what that means?
The oil light flashes but I think it always did that until it started.
Any help is appreciated, I'm goin crazy on this.

 

maybe u hadn't connected fuel pupm? )

 

I haven't touched any electrical on it, but I'll check.

 

is fuel pump kicking on when turn key on? prolly is the tip over sensor, bypass that if havent already, cut and wire the 2 outside wires together

 

fuel pump kicks on, first thing i did when i bought it was bypass the tip over sensor.
I'm goin crazy on this, its probably somethin so simple and stupid too.

 

is it getting spark to good plugs? if not maybe in same boat I am in, but think could be pulse generator, i guess its common for these to go out? either way tested mine and tested my brothers f4i and his was def producing more voltage when cranking on it then mine is doing. I dont know what kinda voltage the pulse generator should be putting out but know my brothers bike starts everytime.
