White exhaust port?
 

Hi guys,

I have the 12A out of my car for the next little while while i put in a new clutch and air oil cooler. I noticed that the exhaust ports were different color. The rear port is very light, even whiteish, and the front is a dark brown. I'm assuming this is from the rear rotor running lean? I have just the stock nikki and emmissions are off. Is this common at all, and doesn't anyone know how to fix it. I was thinking maybe the nipple on the carb spacer that I have connected to the oil filler tube may be going to the rear rotor only and making a lean mixture? If I hooked up that oil filler vent to a nipple on the air cleaner would there be proper vaccumme to vent the crankcase?

Thanks, Matt

ur right the rear rotor might be running lean, keep in mind whenever you get off the throttle fuel is to the back rotor personally i never experience that problem.
