I'm not riding it as much as I did when I first finished it. Probably becuase the winter rains in California were particularly frequent. The little stock oil slinger was aimed just right to pick up oil from the angled sump. If you look at how the seals are lubricated for the camshaft and for the...

Before I decided to do this I took the engine apart and saw what was going to happen. The splash finger hits the deepest part of the angled crankcase oil and it flings it up to the valve area. The oil drainage was modified for crankshaft lubrication and there is not enough oil to back up into...

Some of the parts on the bike are brand new and definitely need to have some treatment to make everything match. Whether that's paint or rust, I haven't decided yet. I've ridden it about 15 miles so far, before the rain came. Next chance will be around Xmas. I'm already convinced that it will...

The little splasher dips into the oil at its deepest part and flings it in the correct direction. I'm betting this engine lasts longer than most people think. I realize that not everyone agrees but I'm willing to take the risk. It is just such a sweet ride, it sounds cool, and it doesn't look...

I guess I just like livin on the edge and testing out new ideas. I didn't really take that much material off the cooling fins. How long do you think it will last? The way that it is setup now, riding around town might get it to a max rev of 3200 rpm. At that engine speed, the engine is...

Oil pump? No it doesn't have one. The little splash finger on the connecting rod flings enough oil in the crankcase to lubricate everything. - boogerballs

I’ve had a new idea for a motor bicycle. I wanted to take a small (2.5-3.5hp) Briggs and Stratton engine and mount it inclined. The bottom of the motor would mount on the seat tube. I planned to have a belt drive with a belt-tensioning clutch. The engine would run to a jackshaft just behind...

Thanks for the welcome. I figured once this introduction was out of the way, I'd go ahead and put up a post on each one in the motorized section. boogerballs

Hey all, Just wanted to introduce myself. I have been browsing the forum/galleries for a couple of years and finally thought, what the heck, so here I am. I’ve been into bicycles pretty much my whole life (57) and even worked for Specialzed for a few. Right now I’m into motorized bikes and have...

The guy's name who's in both videos and who made both bikes is John Buddenbaum. He's a fabricator who mostly works with vintage 4-wheel racers. The approximately 90cc Maytag motor (45cc per cyclinder) he pretty heavily modified (narrowed) to make it work for bike power but still has only about...
