hey guys I just put on my pro circuit ti-4 slip on exhaust recently. Well i took out the baffle which housed the spark arrestor. Is this a bad idea Is it going to run to lean. I have the HRC kit which is a 185 main jet. It does tend to back fire and pop alittle but not to bad. Also if i did need to rejet what would i go with a 190 or 195. what do yall think i need to do rejet, put the baffle back in or leave it.

thanks benard_80

yeah its gonna be lean, which isnt gonna be good for your motor. go up a jet size or two until the spark plug is a dark grey to light golden color.

Yup.. more air flow + same fuel = lean. ;)
