So, what's todays most reliable two-stroke engine?

[tech a]

Got a 97 Poo 700, not 1 problem.....

also have 2 Poo jetski's with 700's....same deal no motor issues
at all...

now my 01 800 rmk....well just waiting for crank/bearings # 4 .......tic tic tic

Yup not even close Stihl weed eater...that thing gets totally abused and always runs perfect

Actually if u figure the motor that has the least ammount of stress on it will last longest if both are designed correctly, so the 600's are a safe bet. My wifes 700 rmk has been perfect so far.
