I always thought that these stories about "only being able to run the 2-strokes for 20 minutes at a time because they'll over heat" were just anti 2-stroke propaganda that was made up by guys trying to sell their (more expensive) 4-strokes.
Eeeb-Eh!Im also thinking of purchasing one of those gadgets that will measure the speed and miles. wheres the best place to get them?
The SAFEST amount of time you can run them is not at all
It also comes from certain factory "instruction manuals" that are slanted toward overkill to prevent returns by inexperiencd buyers. The factory does not care HOW it runs, just that it runs more than 30 days.They were/are.
