Where to start, over about a month and a half every other week I had to keep adjusting up 2 opposing rockers, well I knew what was up, finally swapped out the motor, tore her down and found 2 lifters going flat.
Over the last 4 weeks, I have been cleaning this and prepping that as funds would allow, and getting close for re-assembly, yesterday after going over the 80mm crank and finding some pitting from air bubbles when the jrl's were welded up, I decided to have the crank turned under, well during the grinding process it was found 2 of the 4 jrl's had cracks going from the oil hole to the jrl radius, so the crank is junk. I have a spare crank & flywheel prepped sitting on the shelf, but it's only a 75mm stroke and due to low funds right now it's a cheap option.
So today I was getting some prep work done to a case, and basically the case turns out to be junk. And the sad part, the case was bushed for Type 1 lifters.
I have another case but it needs to be fully checked out, cleaned, line bore checked, holes tapped, cyl spigots opened up, then cleaned again for assembly, basically just everything that was just done to the junk case. It's just more time & money, so maybe next week for the case work ?
Most of the time motors go together with out a single issue they almost fall together by them selves, then on an occasion you get the Domino Effect's build.
Going back and really thinking about it, it could of been greasy finger prints on the jrl's that caused them to crack ?
And if I had cleaned the stains from my Starbucks Triple off the 2 lifters they probably wouldn't have gone flat.
And if I hadn't had my radio to loud the resonating sound waves wouldn't of damaged the case.
So is this enough breakage for everyone ? ...
