Picked up the bike back in the early part of the year. The PO had told me that he had gotten the top end worked on, but it still had a slight oil lead down the front on the exhaust side. That was then, this is the now – I had planned to replace the light switch harness to get the lights going again, along with fixing the front brake master cylinder. Since I needed to pull the plastic to get to the wiring harness I figured it would be a great time to also pull the rocker box cover and regasket so to speak to get the oil leak fixed. First thought something may be amiss is when I saw spare "open" holes in the rocker box – places I knew bolts should be. Taking my time working the bolts out, most came out pretty clean, some have aluminum or either heli-coil material in them. Area of concern #1. Area #2 was when I get to the bolts around the camshaft – the shorter of the 7mm bolts are there (these are the ones in between the sprocket and cam lobes), the longer or outer 7mm bolts (the 145mm ones from what I figure based on parts lists) are MIA! When I get the rocker box off, I find major area of concern #3 – there is significant damage at the inner bearing area (see photos) and the cam lobes look have an odd wear pattern. Here’s the questions – (1) Am I looking a replacement head and cam? Are they even in production anymore? (2) The 6mm bolts that have aluminum in the threads – do I need to be thinking about something like a heli-coil for those areas or how do I remedy? (3) Or do I just need to button it back together, get some OEM replacement 7mmX145 bolts and hope for the best? The bike was running ok – tended to be a little iffy on cold starts – just trying to figure the best course to take. Still have to do the wiring harness and front brakes…..
