1st post, newbie to motor-bikes, lotsa knowledge of small engines as in quads. I'm nearly finished installing a BGF 80 (69?) in my old Autobike Classic. Thanks to Pablo and Ghost0 among others, I'm also tortuously waiting till Tuesday to receive my Jackshaft kit, so I'll end up with a 6 speed automatic tranny. Installation is going well, so far.
However, I'm a little concerned about the manufacturer's recommended break in procedure. Running with a higher than normal fuel/oil ratio during break in makes the fuel/air ratio somewhat leaner. (more oil means less burnable fuel volume, air volume is the same... so a/f mixture is leaner) Running leaner typically makes the engine run hotter and also promotes pre-ignition and it's resulting damage to piston, etc., neither of which I think is a good thing for an engine during its break in period. I am used to running a rich mixture during break in, especially on 2-strokes... but since i have no carb control over the mixture - only the fuel/oil ratio controls the air/fuel mixture (without re-jetting) - I am forced to run lean if I'm going to add extra oil during break in. Catch 22?
I was wondering if anyone here has had similar concerns and perhaps solutions or whether I am just being my normal, over anal, engineer self?
Glad to see this site is here!
BTW, can anybody tell me who is the real manufacturer of the motors distributed by Boygofast?
Thanks
