I do believe that's where you run a hose to your charcoal canister (emissions crap). So no doubt someones ripped it out as they are useless. Not sure what size hose it is, mine just has whatever was on it cut short with a screw in it to block the hole off.
After staring at it intensely for a couple minutes and trying to imagine what it could look like, I kinda like it. It's different and adds a different style to it. Guess we'll see once there's a photo of it all bogged up :y:
Looking good mate, if it were me respraying it, I wouldnt keep the stripes.. but thats my opinion, others would disagree no doubt.
Needs more low at the front!
