3 chain, 5 chain question

[Ebell914]

So, let me ask - what is the general consensus on reliability of the two? Major drawbacks/benefits of each?

5 chain engines have more components to wear. They also do not have load sensitive variable valve timing, its a mere RPM switch.

There's a ton of benefits in 3 chain over 5 chain, it would be its own thread for sure.
