how many tanks...

of gas should these trucks go threw before we start to be concerned about the engine starting wear out ? time to rebuild, losing performance, replacing the engine etc. thanks in advance

Kind of hard to say...I think a lot depends on fuel mix/ tune, and mostly how good the air filter / maintenance is.

Also the conditions it's run in, sand dusty, compared to running on grass etc.

how many tanks...

A well maintained engine can last 100 hours. Most upgrade before that for more power.

I say 8 or 10 hours then a ring change.Now that's a full 8 or 10 hours of run time,you take it how long do you get out of a tank of fuel not long.Whats a $6 ring and $4 gasket once a year or even 2 or 3 times.It's cheaper then head kits once the ring digs in the bore wall.

If you know any dirt bike racers ask them how long before a ring,piston and head change. The old 2 stroke cr250 is just a bigger engine but still takes the beating as the small engine in the dirt.
