I've owned a couple other 2 cycle engines before,,,specifically my snow blower and a 90HP Mercury outboard (which was a 6 cyl).
The Merc was already broken in when I bought it and the boat, so not sure what the procedure was on that.
The snow blower was bought brand new and there was no specific "break-in" period. Just crank it up & blow snow.
However, on the 50cc RH engine, the manual (and I use that term loosely) is very specific regarding proper break-in. Max of 1/2 throttle for the first 150 miles. Then between 150 & 500 miles, max of 3/4 throttle. Are these engines really that delicate? Or are the recommendations just super conservative? It's taking forever to get to 150 miles when the fastest you can go is 25bmph (22 actual). Then to get to 500, another 350 miles, at a max speed of 37bmph (33 actual) is going to take forever again because the main roads around here have 40 to 45mph speed limits and I don't want to get run over. So I have to take sidestreets,,,,,,,,,,,,,,,,,,,,,,,,,,,,,after an hour of that, I'm mentally fried and have traveled all of 10 miles with a stop sign every other block.
How have you other 2T folks handled the breaking-in of your scoot?
Thanks,
Tom

Thank you and done!B02S4 wrote:Make sure it is fully warmed up & then give it a cycle of 5 to 10 good bursts of accel/decel to help seat the rings...
Should I now consider it broken in at 95 miles on the odo?

Tom,
Just met you yesterday on Fort Street.
A good friend of mine who has ridden just about anything you can imagine, and has restored some rare and common bikes, doesn't believe in babying a new engine other than ensuring it's properly warmed up before you run it hard. He says, "Ride it like you stole it."
Another guy, who used to sell and service Tomos mopeds, tells me that you should run it until it's hot, then let it cool down for a while, and then repeat the process a few times during break-in.
Based on my experience, I'd probably avoid running that Roughhouse flat-out for extended periods of time until it has a few hundred miles on it, but I wouldn't be obsessing about it at this point. Just have fun!
BTW, use plain ol' regular grade gasoline and synthetic two-stroke oil.
