Break-in Proceedures/Reprise
Hi Augidog, I've been a mechanic for many years, working on everything from Model T fords, to Hay Balers, and Haro-beds as a Ford and New Holland dealership mechanic when I was young. I drove my 55 chevy BelAir up to and walked into a Datsun Dealership at 18yo and landed a job as a Dealership Line Mechanic. Just a brief to let you know that I am very familiar with things mechanical.
After these engines are "prepped" there is NO need for all this over-oiling, babying, and carrying on about the preciuos "break-in time".
Prep:
1)open the clutch cover and lightly grease, with non-migratory grease, the two crude helical cut gears.
2) Open the clutch arm cover, remove clutch arm, pin and 8mm BB and grease them also.
3) O-ring the carb, and chech the bottom of manifold to see that the gasket is intact (they are a continuing problem)
4) Mix fuel 32 to 1 Organic 4 oz 2-stroke oil to one US gallon of regular cheap gas
5) check everything
6)start engine and ride briefly ie around the block one time
7) check everything, all nuts bolts chain tensions etc
8) ride it like you just stole it!!! There is NOTHING inside here to break-in, no cams, lifters, babbit bearings, pushrods, rockers valves valveseats NOTHING!
Now..... Never lug a new engine, never get it too hot, and do not run wide open at no load. all these things are important.
To JosephGarcia I have many engines, 2-stroke chinese all the way back to 2 of the Spitfires, Whizzers, and I'm assembling, at this time a lil 4-stroke chinese with a gearbox on it's side.
I hope my lil outline will help people enjoy thier engines. The over-oiling causes hard starting, lack of power, pollution, and aggravates neighbors at least a little
Gentlemen, start your engines
