[QUOTE="sandflyz, post: 995430, member: 57556"] yeah thats exactly what mine looks like. I feel better now. Its the worst shiny spot in my cylinder so i guess i'm ok. I got worried a bit as my dealer said the plating was only .002" thick. So if the rings are rubbing a high spot or something you gotta know its not going to take long to rub through the plating or snag a ring. Did Eric Gorr do the porting? How did you like it? If he milled the head or cylinder did you have to round out the top motormount holes to get it to fit back together? Oldfrt613 above sais its not an issue. I put the JD kit in mine to clean up the jetting and bought a V-force2 reed block. Right now it runs strong everywhere. Actually i emailed jd jetting and told them i was using the leanest needle in the first clip position and wanted to get some porting done on my bike. I said that since I am already in the leanest position i was worried that porting my bike would render my jd kit useless if i had to lean out any further. I got an email back an hour later telling me they would send another leaner jet needle to me free of charge. Great service and a great product. The Mikuni is a handful otherwise. Anyway, I figured since i was putting a top end in and had it appart i might as well send it off to Eric for the Mo-Betta everywhere. Thanks for the pics sandflyz [/QUOTE]
