Bonneville America Forums Forums Off Topic Discussion Forums Lounge 150,000 and engine ware

I had the gasket and washers on the engine above the head replaced.
The mechanic Daren from Redline power sports, Winsted, CT
Informed me there was ware evident on the timing chain and some of the rollers.
At fist I was bummed out about that news.
But after all the 2006 America has 150,000(+)
What did I expect a like new engine?
One thing I'm surprised with the front and rear tire bearings have never been replaced.
Hope I didn't jinx myself.
