Are they ok engines as far as reliability and power or are the zenoah engines much better?

I am running a CY23 with a samba pipe and I can't complain.

CY is sold under several names, some of them are SiKK and Superior.

I have an SiKK 27cc big bore kit on my Zenoah G230RC, and I can't complain, runs as good as my friends Zenoah G260RC4.

The CY engine and the Zenoah are 99% identical. Speaking of the 23cc versions, the Zenoah claims to have improved the ignition/magneto system and it uses a thinner piston ring and washers (#25 in Zenoah manual) to "enclose" the upper part of the conrod where the roller bearing sits. Everything else is the same.

I've disassembled both inside and out you really can't tell any difference between both parts. Ask anyone in this forum and they will also tell you there isn't any noticeable power difference between both 23ccs. Both are rock solid, reliable engines but since the Zenoah is made in Japan, people just tend to prefer that particular brand.

Zenoah produces 23cc and 26cc for its car engines and CY/Sikk produces 23cc, 27cc and 29cc displacements for its car engines. It would be competitive if large scale can be bought without engine option since a 23cc CY engine costs U$134 (for a whole engine) and the top of the line 29cc costs a mere U$169 or U$184 with a lightened crankshaft. This is as powerful as stock motors you can buy for large scale without porting which is an absolute bargain compared to nitro motors' prices.

I stand corrected! However, it seems the 23, 27 and 29cc are the most popular

That's cool. I wasn't for sure on them and have heard people talking about upgrading to high displacement Sikk engines but I didn't realize that CY and Sikk were the same. I've been hearing about people really liking there 29cc Sikk engines and they say that they have a lot of power. I always look at reliability too but have heard that they are pretty reliable too.

We've moved a ton of these motors and our customers have been generally quite pleased with them.
