Posted this same issue on amsnow.com but want to ensure everyone at least checks there sleds. Last night I decided to reburp my f-7 with the new and improved version making a long story short I wanted to recheck to make sure no oil bubbles when I noticed that my secondary had rubbed a flat spot on my oil line, thank God and I do thank God that I noticed this before "meltdown". Went today and got the oil line fixed from my dealer they did an outstanding job rerouting the oil line and and putting a small spring around the entire line to ensure no more rubs. Looked at other f-7's while I was there none of the other ones looked like this would happen to them however, there is a recall (straight from the dealers mouth) on a electrical line coming out right next to the secondary I would recommend everyone check there f-7's next to the secondary and see if there is any possibility of anything rubbing when it is open all the way. The tell tale sign to this electrical malfunction is irregularity in the tach, don't know exactly what but I believe it was jumping all over the place. My dealer ordered 20 of the new pull cord "fixes" but he believes it is simply a button or something they are putting in the dash. Sounds stupid and won't fix the problem will update when I see it. Anyone else no of something different?
