Just make sure you don't buy a new one (F-250) Lisa ... unless you can trade it in every 4 years or so ...
I have more confidence in Ford than GM these days, but not enough confidence to buy a new one.
Wow what a mess Sunny! Looks expensive!
I run my 2-stroke RD at .002" clearance, but the bore is only 64.5mm ( a little over 2.5" ). Stock actually calls for .0016", & I would've preferred that .. but the machine shop just went with .002" . One cylinder is just a touch noisy, and the other is silent - I'm guessing it's because they didn't label the pistons left & right ... so I have no idea which one was measured for what cylinder. Hindsight is always 20/20 ... but the bike runs VERY STRONG so I can't complain one bit.
Knock on wood, I've never seized an engine before in my life. Spun bearings ... but never seized. (I'd better shut up!)
WOW Greg - I guess that engine has seen some serious run time over the decades with that kind of wear! Too bad it didn't have an hour meter from the factory - that would be interesting. Probably pretty close to the wear on my original Blazer 4.3. When I removed the heads, there was a giant ridge at the top! Not only could I feel it, but you could SEE it. Never measured it, but I could tell it was gigantic - like 1/8th inch at LEAST. It's a wonder it even started in the morning! That engine burned a quart of 20W-50 in 15° temps every 50 MILES!!
What a smokeshow when the wife left for work in the morning!
Here's a pic of the exhaust when she started it up near some snow ..... check this out!! Just a few revs of the engine here ...
