Hi Everyone,
I have two Super Cykes, one is an original and the other is a not yet run reproduction.
The question is, it it better to have the exhaust pointed to the outboard side or the inboard side?
Since the reproduction has not been run, I can turn the cylinder to have the exhaust on the outboard before the initial run for breakin.
Thanks,
Stan

Stan, I find it best to have the exhaust stack pointing to the outside of the circle so as to annoy as many as possible! y1 y1

The Super Cyke, as well as Anderson Spitfire, can have the cylinder turned either way. Don't forget to also reverse the piston! You will find a spacer that installs on the piston pin. This must be on the back side of the piston. So if you turn the piston around, this spacer must be also put on the back side of the piston pin. The spacer keeps the rod from hitting the carnkcase back plate.
These engines run the same with the cylinder placed either way.

I have taken Super Cyke's and Anderson Spitfires that have been run quite a bit and changed the piston cylinder to get the exhaust to the outboard for control line. I usually run a few tanks throught them on my test stand after the switch, but they seem to run just fine. I know my Andersons have the spacer on the back side of the rod, but my Super Cykes do not.

Way back in the 50's we had a chap called Jim Watson, who turned out every year with his Dooling 29 speed model. Never won, always did the same speed, (moderate). Eventually he wore it out, but turned it round and started again! Are you still there Jim?

Thanks for everyone's comments.
I think that I will turn the exhaust towards the outside of the circle. I'll be sure to have hearing protection available for the poor guy that pits for me.

Are the Super Cyc's or Anderson's ball bearing on the main shaft or bushed?
Best, DennisT

Super Cykes are bushed, and Spitfires have a ball bearing at the rear, with a bushing the rest of the way forward. The Super Cykes also have a thrust ball bearing that runs between two thin steel races. These can be trouble. I have had them split where the balls run, and then they come apart and destroy the piston/cyl. Severall of my friends have had them do the same thing. I have since replaced all of mine with bronze bushings. They run just as good.
That is a good idea Stan. They soon learn how loud these things are, and then you run out of live stooges. LOL I try to always have ear protection for my pit man for both sparkers and Fox 59's.

Not as strong as a good Super Cyke, here's a vintage O&R 60 "special" chugging happily along. This is the second model but still with the small exhaust port.

Nice photo, pristine engine. Takes me back to 1946. Is that an AEIOU in the background?

The black box contains spark coil, TIM-4 transistor coil driver, battery pack, switch and LED. Makes quick work connecting any sparker to the test stand.

'Bout the same as the one I built for Frank McMillan. An "Acme Electronic Ignition Operation Unit".

Mine is in a Nestles Quick box. Even though it is yellow it still works. y1 I built the test stand about 30 years ago to run a then new OS 60 four stroke. It has since been modified with a commercial test stand bolted to it. I think I have as much fuel run through engines on here as in flying planes. #^ Not sure, but I think it is addictive.

HeyJim. How did you manage to post a picture with 187 KB size? I have to get my pictures "pixelized" to 45 KB before the forum will accept.

You can go big on this forum Floyd. I think a 1,000 KB per post.
