Is it ok to take the spark collector off the tip of the exhaust? I like the sound with it off but i want to know if its going to cause trouble with it off?

 

You may have to increase main jet size a little. Check your spark plug at various throttle settings, mainly mid to upper rpm to see what color it is and if too light or white you want to increase jet size.

Personally, I prefer my plugs a good tan or light black in color. More margin for error.
