If you look at the piston it should be obvious that the Dykes top ring you have pictured can only fit one way. 

 

Thanks I can see it now.
those parts are nice aren't they?? 

Like jewelry! 

The location of the pin in the ring land and the bevel on the ring ends also is a clue to direction.
Bune does hella good work, fixed up my buddy's '67 Suzuki Hustler 250 twin crank that had a LH crank half let go. Took to complete cranks but 2 make 1 and bike still runs phenomenal!

I just had my 2nd cylinder in about 3 months bored there. The Honda C100 is now 0.50 over. They do great work and excellent service. What i like is i send the cylinder out on Monday including a return FED EX label and i see the cylinder back by the next weekend! less then 7 day turn around including shipping here to Michigan. Can't beat it. 

Just put the Honda C100 back together this weekend. runs like a champ with it's new bore and valves. 

 
 

Really good simple little motors those C100's [50cc for them that are wondering]. Even used our one at work in the early "60's to tow brokendown bike back to work from around town. Bike almost never cooled down during the working day as everyone used it.

They had it on a Monday and it was here in one week. Amazing.

Still waiting for carb. Starting to think maybe wait til April to final assemble..we shall see.
