Fantastic work Sportscar! Im wondering though how well the motor is lubricated at the upright angle? Special oil pump pickup?

Here is a detail shot of the finished engine mount assembly and the mock up I used to test fit to the frame. Mount is CAD designed and laser cut to insure accuracy, then placed into the frame and squared up off the frame jig to assure proper chain alignment. The three pieces of the mount are tabed and slotted together so they self align and interlock before welding. Very easy to assemble and maintain alignment through the tig welding process. I like how the main backbone of the mount looks kind of like a big bowie hunting knife. I will try to keep this thread updated as the build continues.

So; It would be OK to mount the motor in a configuration like this old Indian if someone wanted the layback look??The new connecting rod end cap has a wider "spoon" that not only splashes more oil but it force feeds the big rod end bearing, something the stock rod cannot do. As long as you slightly tilt the cylinder rearward a couple of degrees it oils just as well as in the stock configuration.
Very impressive what you guys are doing with these engines. I know the initial cost of the Harbor Freight engine is quite low, but what kind of money do you have in one "souped up"? I know there are different stages of upgrading, but can anyone give an idea?wow Pat, she is gonna be a beaut! with the added performance parts, a screamer too. I am sprucing up my engine as well. cam, valves, con rod, piston, pushrods, flywheel, rockers, springs. bet i easily hit 10 horses. I will just ease on the throttle though, so I dont break spokes.
Pardon my fumbling with the words, (I'm better at drawing pictures). Perhaps some kind of transitional "partial" gear that could be turned so the "teeth" contact the flywheel at the front and the pedal at the rear. With the bike on a center stand, just mesh the gear into the (customized?) flywheel then set the pedal against the other side of the gear, then kick start your engine! That is of course, if the flywheel is designed to rotate forward. I dunno, it works in my head.Now if someone can just come up with a kick starter.
