quick question, i have my exhaust off to polish it since it was lookin like trash, and someone talked me into thinkin it was a good idea to start my bike up without the slip-on. just to see what it would sound like. started it up fine gave it a lil rev and it shut off, now i cant get it to start up. any ideas? im thinkin maybe fouled out the plugs? i didnt realize no exhaust would cause problems right off the bat like that. i kno riding without one and not tuning the air/fuel can be bad it will run too lean correct?im gonna throw the slip-on back on it tomorrow or the next day when i get a chance and see if that helps.

 

I'm still learning alot but, 2 things came to my mind.

1: O2 sensor related?

2: Insufficient back pressure (or is that just from the headers)?

 

bump...anyone??
