how much does it cost to maintain an lt250r? as in how often do you have to do rebuilds?

I put in about 100hours per year, so every "how many" years do i have to do a rebuild? (and what does it consist of anyway? piston and/or rings, gaskets, what else?)

and how much money does it cost each time when a rebuild is done?

Some people say that pretty soon companies will stop making parts for them, so would it be wise to keep a supply of pistons, etc, or would they corrode/rust after a while (or do they ship in airtight bags/containers?)

PS: Could the transmission be worn out and start breaking on a quad from the 1980s? (because if they ride it 100 hours each year for 20 years, that is 2000 hours, and if you drove a car at 60mph for 2000 hours, that means 120,000miles on the car- and most breakdowns occur in cars with over 120,000miles on them)

 

You dont have to rebuild a four stroke engine unless you have a 400^ and you race. Or if you blow up a 250 engine which is almost in possible. all you have to do is change the oil.
