Hey guys, I honestly thought there would be a plethora of info out there on rebuilding these engines by now but either I must be looking in the wrong places or all the knowledge is buried in the ground with people that worked on them because I haven't come across what I'm looking for
Most of what I can find is in the service manual itself but unfortunately it leads me to a dead end.
Long story short, I picked up a sad looking 74 or 1975 KE100 with 5000 miles on it and I was able to get her running pretty quickly however she had a very noisy engine.
I took it apart to discover a pretty scored up piston but the cylinder looked fairy decent. So I figured depending on what the measurements were I would hone it or send it out to be bored.
Now if anyone could chime in with info that would be great but from my understanding, this cylinder does NOT need to be nikasiled, correct?
In any case, the more important part of the question is about the piston size. Obviously this engine must've been oversized because the piston is measuring at 50.3mm and the cylinder is at 50.49mm. Based off everything I've found, 50mm is the largest you can go, so where does that leave me?
Does anyone have info rebuilding these engines? Is it possible to get a 50.5mm piston for the KE100 or should I say is it even possible to go over 50mm? Everything I find only goes up to 50mm for the G5. The only 50.5mm seems to be sold for a KX85, would this work?
I guess I could try and find a jug in better condition but I feel like thats going to be a gamble. I might get something in even worse shape.
Again, if there's anyone out there that has done this before or has any info I would very much appreciate it
Thanks, JW
