Default H Whizzer on Schwinn-Older Restoration

I made a new friend at Donut Derelicts Saturday and he asked if I could get his Whizzer running. In his rafters since 2005 it had a ton of dust on it. He took it for a debt owed. I don't know the amount but the owner told him it was worth $6000 and ran. After telling him you can find good running Whizzers for around $2500 these days, he was a little disappointed. Then I pointed out all the upgrades on his and the value made him feel better I'm sure. It has an H engine with a tall breather, high fin head, echo pipe with finned aluminum elbow, automatic clutch, Whizzer twist grip throttle and matching grip with compression release lever, Schwinn front drum brake, rear wheel stand, large rear fender reflector, brake arm extension, locking springer, Torrington pedals, front fender light, nice 4 hole rear rack with tail light, cross bar handlebars, nice paint and pinstriping, beautiful tank with original type decals, very nice winged chain guard, and Schwinn embossed seat. Now the bad news. It had a plastic dipstick, broken magneto cover, cracked belt guard, 1 missing engaging dog on the clutch, and when I put it on the stand and turned the pedals I noticed excessive end play on the crank and it sounded like the piston was hitting the head. So next I'll pull the crank and see which end of the rod is toast. Looks like the bike will clean up real nice. Most of the chrome is still pretty good.

He was very lucky to get anything on the bad debt and even luckier to have run into you. Sounds like you will get the bike sorted out. Keep us posted.

Thanks Zip. The first thing I noticed after removing the side cover is the crank end play shim has spun a few degrees. Not totally uncommon and probably due to improper fit or lack of lubrication. Then I saw the dipper missing from the rod cap and the big end has a lot of play. After fishing the broken piece from the bottom of the crankcase and removing the cap, I see the crank is marked .040 and the bearing inserts are wiped out. Also the crank pin is .004 or .005 out of round. The piston is .030 over and has some chafing. It may polish out and the cylinder may just take a light honing. I got the go ahead to purchase the needed parts, so I'll contact mason man for some advice and encouragement.

I've done a few but cranks, rods and pistons are getting harder to obtain.

Ran into John Koehnke at the next Donut Derelicts and he said he could take care of the crank and rod fairly reasonably. He carries rod bearings down to .050 under and can tig the dipper back onto the rod after resizing it. I need to get over to his place next week.

Thanks Ray, I'll keep you informed. I pulled the motor today and will get all the parts cleaned up before I head over.

That's a nice bike. This is interesting reading. I put 4 new vintage clutch dogs From Ron on my bike a while back. They work better than some aftermarket ones I've had. I found a little piece of metal on the floor under the bike I put them on a few months ago. I realized it was one of the dogs. 3 are working fine for me since then.

I'm curious how you were able to assemble it and have one of those fall out on the floor. Was it ever in there? Or did you park your bike over your mistake?
