YS manufacturing ain't what it used to be. I just replaced the crankshaft in a 1.10 and found the valve lifters are different lengths. 11mm and 13mm. This makes four new YS engines in the past year that have had manufacturing defects.

Me thinks the increased demand is exceeding the manufacturing capability.

I will still continue to buy and us them because there is nothing else comparable.

Probably no worse than it ever was percentage wise, based on the past 6 years we've been importing the line. It still doesn't thrill me when I hear things like this.

I hope you've called service for some new pieces.

AMEN.

aw

You guys would know. Maybe I am just unlucky recently but I never had problems like this until they became hard to get. In the past, when I needed parts or an engine, I got them immediately. Now I have to estimate my needs in advance or wait for the YS boat to come in.

I was introduced to YS engines 7 years ago and have been abusing them ever since racing warbirds. They take a licking and keep on ticking. The .91 was an awesome engine and the 1.10 is more incredible.

From now on, I am going to completely disassemble all new engines and make sure there are no obvious problems before breaking them in. This is not a bad practice anyway to make sure there is no manufacturing debris inside.
