... and by the time I make the 40 mile ride home it's a little more than a tick... As the picture shows it appears the cam cap bolts came loose. Yeah, no... Found two broken bolts (front) and two bolts containing the threads from the head (rear)
Replacement head is shipping. I did see some slight scouring in the journal itself. I haven't looked any deeper as night fell.
Since I am going to be down into the jugs (broken tensioner bolt and reseal) if any of you guru's out there would like to share a couple of insider tips I would be thankful. I am looking for the tips that I am not aware of since this is my first inline 4 from the 70's that I've had the pleasure to tear into this far...(I'm actually 10 years older than the bike thank you!)
Aside from the multiple broken bolts this engine looks pretty good.
BACK STORY ---> It all started when I traded for this '77 GS750B. Didn't run, no spark but complete w/extras including a side shaft 5.5hp Honda that runs LOL. Diagnose defective coils. Ordered, replaced, runs. Fouls plugs like I own NGK... Pull the carbs, rebuild (thanks o-ring dude, you done good!!!), re-install, tune with one missing restrictor for the vacuum gauges, runs fair, not fouling plugs. Idle is sketchy but do-able. Take out for the weekend. Ride her with enthusiasm. Starts the tick. Figured the T.C. tensioner needs addressed. eb*y the goods. Pull the carbs (step up on the pilots/float bowl gaskets) install completely resealed T.C. tensioner. Start engine, still a pronounced tick and the carbs are f'n killing me. Pull carbs and Sunday breakfast on my counter top was a bowl of oatmeal, mug of green tea, a flashlight and four carbs pulled completely apart because the slides couldn't close completely. I am not sure the technical name but I'm calling it the dog bone that connects throttle bracket to the slide, the spring inside was maintaining tension, putting the dog bone in a bind causing the slide to ride up in it's bore. Fix this issue with my trusty dremel and I have the slides dialed in, up, down and wot (1mm above) adjusted perfect. But before we put this on lets pop the valve cover for inspection.
I know sit before you with a set of dialed in carbs and this picture.
... and $300 dollars worth of replacement parts/tools/goodies randomly showing up in my mail
