New member! Help me tell what cc my zongshen motor is???????

This would be a little shorter https://www.amazon.com/GOOFIT-Intake...ntake+manifold but looks like it still won't give you enough room.


Edit: After looking at it some more. Your existing manifold comes out straight. The new manifold will put the carb level angle it to the right toward the spark plug enough to miss the frame.

Typical readily available options https://item.taobao.com/item.htm?id=535417250779 doesn't fit that space

I have one CG engine labeled 171FMM which would indicate 71mm bore, 250cc class, but I measured it as 63mm bore 62.xmm stroke which makes it a 200cc. The correct designation would be 163FML so you can't count on the engine numbers being correct. Maybe it's a 90cc

One of those should work. Just have to figure out which one.

[Ironmike]

Thx for all the quick info guys. Great site! Ive been a member of many sites and love the quick responses/good info im getting. Appreciate it. I checked and didnt see cc marking on barrel/fins ect. Guess i have to assume its a 200cc? Ill take a look at those intakes when i have more time tonight. Supossed to be working lol. I know its not a 90cc (i know you were joking) as it suprisenly moves the blaster quite well with my 200lb ass on it. Done all the fast atc's,atv's,dirtbikes. Just looking for something cheap/depenable to beat around on

[Ironmike]

Any other info/mods things i need to know about feel free thx!

I would replace the exhaust header pipe. If the welds on the inside are anything like the outside it may be restrictive. here's a replacement header pipe that should work. http://www.ebay.ca/itm/Exhaust-Head-...NY1HhD&vxp=mtr Carb tuning might be something else to look at once you replace the intake manifold.

Ya welds are pretty ugly. Wonder if bend in that pipe would work? I checked the plug and its running very rich. Cant remember off hand but think it was ngk dp8ear? Does that sound right. From what ive read i should be running d8ea? Theres no air filter on it so im surprised its running so rich. Ive also noticed the guy has a procicuit 2 stroke silencer on it. Thats causing a problem?

The bend in the header pipe should be good and muffler should be good too. Any adjustments to the bend to make things line up can be done at any muffler shop or as I would do with a torch and vice. A NGK (4929) DPR8EA-9 (Copper Core) or NGK(2202) DPR8EIX-9 (Iridium) will be fine. I would install an air filter then tune the carb.

CG clone engines like the one you have are highly reliable and Zongshen is a good brand. You can read about the design here. http://world.honda.com/history/chall...125/index.html

I seen hp/tq #'s all over the place for the 200 and 250 . Can someone post the true hp/tq each motor makes. I know it's never gonna be a speed demon but what are some recommended proven hp mods? Thx

It's running rich because the carburetor mouth is so close to the frame, which increases vacuum in the carb, causing it to draw more fuel than it should. Any after-market intake tube that moves the mouth of the carb. away from interference of the air-flow to the carb will make a big difference in how well it runs, and power output...ARH

Thx for info. What's stock mixture screw/needle setting? Need a starting point so when I get the new intake. Hopefully I have little more room. If not I'm gonna have to just clamp on some sort of airfilter foam right on the carb. I know it's not right but it's better then no filter . Just took the intake off. It's def home made. Very rough inside.

Welcome!


This is all very familiar... A few years ago, forum member TeamCheap installed a CG motor into an old Blaster and documented the whole deal. Unfortunately, Photobucket has changed their terms and none of the pics show up. There is still a ton of good info to read, though: http://www.chinariders.net/showthread.php?t=2321


I have a China quad that is essentially a Yamaha Blaster clone with a CG engine, and this is the intake that is used: http://www.ebay.com/itm/27mm-Intake-...%257Ciid%253A1
It drops the carb and moves it back significantly, but it works. I'm running a 30 slow jet and a 110 main at sea level, with the pilot mixture screw out one turn.

Thx for the link. Just got done reading. A lot of good info! I'm still getting used to reading the # pages in reverse lol. I ordered the intake that another member posted in this thread. If that doesn't work I'll look into the s type intake.
