My Skyhawk frame is now a (barely) functioning ride. Tires, tubes, & front wheel arrived the past couple of days. I created a rim strip from an old tube, got everything mounted, replaced the rear axle with one that gives me some room, & dug through parts until I found a seat post, chain, and a unmatched set of pedals.
I've almost forgotten what it's like to use a coaster brake! Definitely some refining to be done, but the bicycle is here. Pretty soon it will be time to begin on the motor-bicycle.

Pretty creative - worth remembering.

I found out the hard way that the factory will use mismatched parts. If they got the wrong cylinder or a piston rod too long they'll just add gaskets to keep the piston from hitting the head. ALL they care about is getting yer money out of your account. EVERYTHING ELSE is YOUR problem. And yeah, ya gotta inspect everything.

Replaced throttle and clutch cables on customer's bike and readjusted clutch, added a few more coats of grabber green to the specialized frame's front triangle, then I will redo the rear triangle in semi flat black, I've also stripped the original yellow paint off the rear spring so I can powder coat it lime green.
Got the presta valve adapters in the mail today so I could put air in the fixie's tires, and hopefully this weekend I can have an engine installed in that one so I can have something to ride while I'm redoing the mountain bike.

Xseler, can you tell me about the direction your head is facing? I thought slant heads were supposed to have the plug facing forward for some reason? I don't know it if matters and I realized I don't have any idea why I thought that. Does it not actually make any difference?

You can run the head either way, I found on one of my engines that it runs better with the spark plug to the rear. I don't know if the head mates the cylinder better or what the difference is but I can tell it.

I've done it both ways. It doesn't seem to make a difference. I did it usually because of the CDI and where I wanted it mounted. To keep the plug wire off the head. But performance wise I could tell no difference at all.
