FYI, the aftermarket flywheel for the Honda/clone engine will definitely NOT fit my Robin EX-17 engine. The Robin's tapered shaft is too thick, so the ARC flywheel that I have will not seat. Besides, the Robin's key is too thin. A new keyway would have to be machined on the ARC flywheel...

Thanks. Very helpful information.

Limit FYI, I'm looking for a mildly-modified engine worth $400 or less.

Hi. I want a mildly-modified 6.5hp Honda GX200 for my bike. I'll even consider a clone. What I need is an engine with a billet rod, maybe a little extra goodies. Please pm me with what you have.:thumbsup:

Small world. Noblesville had population of 7,548 in the 60's. I was in 'Nam with Kurt Voit W.... He said his dad was mayor there, back in 1968-69.:thumbsup:

Thanks for the tip, texasfabguy.

No, that's the keyway(groove). The woodruff key is several ten-thousandths of an inch smaller. It is much easier to measure. I know the Robin key is smaller than the Honda's. I just wanna know the difference. Motra, you might be right about that timing difference. Thanks for taking more...

The thickness of the woodruff key would be nice to know.

r_chez, can you measure the woodruff key's thickness? Yours look thicker than mine. If it is, then a new, thinner keyway would have to be machined onto the new flywheel. Too bad you couldn't measure a crank that was still in the block. I'm having difficulty comparing my crank...

Thanks! Wow!!:thumbsup: EXCELLENT descriptions! Yeah, keyways are hard to measure. The key was MUCH easier to gauge. Thanks again, man.

Thanks for your offer, man. Yes, that Robin wheel IS heavy, lol. When I removed it, the Robin seemed VERY light. In fact, with flywheel, pull start, tank and air cleaner removed, my EX-17 weighs about 20 lbs.!:thumbsup:

Something like this? Go-Kart Mini-Bike Max-Torque Belt Drive Clutch 3/4" | eBay They're more expensive that sprocket clutches, though.

Hi. I'd like to install a billet flywheel onto my EX-17 Robin. However, the vendors I've contacted don't have aftermarket 'wheels for it. No one knows if the Honda/clone flywheel will fit any Robin engines. If someone out there can post specifications on Hondas or clones, I can compare them...

That sounds promising. Mainly what I need is the flywheel and the connecting rod.

Thank you for your insight, Newoldstock. I'm mainly expecting reliability from my Robin or any clone/Predator. Any mildly-modified 6hp engine will be more than enough for my needs. I bought my new Robin years ago on Ebay for $105. The crank was jammed; that was easily fixed when I removed...
