166 FFM Engine

PALE · 07-31-2011, 07:21 AM

Hy i have china bike Chituma with 166 ffm engine. I bought it with low kilometars, and this engine spends a lot of oil. I guess thats piston rings od valve rubbers ( I`m not sure if that is real name in english ) are in bad shape.... I hope you could tell where I can buy those parts or if someone know dimensions of piston rings for this engine? I tried to find service manual to download but i haven`t found it....If you can help me somehow I would be grateful!!

223 MD33 clone? I will bet that is powered by Zongshen or other smaller brand, similar story heard in chinese foum 8O BUT not Loncin / Jialing

IF want to burn $$$ Genuine Honda SL230 (a domestic market model) parts will fits.

So you are 100% sure that parts fit from honda to my engine?

I have opened this engine and found piston in very bad shape...I really need to change piston so I`m looking for new piston but nobody has any spare parts for chituma around here. If piston really fit from honda then I`ll buy piston from honda.

If your piston is bad, I would look closely at the cylinder wall. Replacing both piston and cylinder is a common venture. They are available in combination from a lot of sources. Likely the Brozz piston/rings/cylinder will be a bolt-on, see here:

Note the image(make it bigger) and you will see the cylinder head, which should confirm the part is correct.... I think. Mebbe yours is smaller bore??
