I was just wondering if it's safe to run my 700xx without the spark arrester? Everything is bone stock, so I was wondering if the stock fuel injection will compensate for the change in air flow? I tried it without the spark arrester in, and it honestly had alot more power! I also did a plug check, and it seemed ok. It looked like the tip of the plug was a light grey. I was just wondering what you guys thought because I don't want to run too lean and hurt my motor. All feedback will greatly be appreciated, thanks!
