Good info !
Thought I would post this info I came across while researching my motor cc. Not sure if it's been posted here before but here it is.
Standard Chinese motorcycle engine identification. Example LF163FML-2M First letter or two indicate the manufacturer. These may be omitted. LF = Lifan, ZS - Zongshen, etc.. First digit indicates the number of cylinders. 1 in the example above. Next 2 digits indicate the bore in millimeters. 63 in the example above. Next letter indicates cooling method. F=air cooled, M=water cooled. Next letter indicates use. M=motorcycle Next letter indicates displacement. J=150cc, K=175cc, L=200cc, M=250cc, Any letters after the dash indicate model version. In the example above the 2M is the engine equipped with a balance shaft. The 142cc engine in my little bike is 1P55FMJ-2E10 so it's a single cylinder, horizontal (P), 55mm bore, air cooled, motorcycle engine, 150cc class, model 2E10. The 200cc engine is the Roketa is 167FML so it's a single cylinder, 67mm bore, air cooled, motorcycle engine, 200cc class. |

Good catch, HB. I forgot to mention that I'm running a Mikuni.

Click on User CP in the upper left corner of your screen, then click Edit Options in the left pane, scroll down to Thread Display Options to arrive at Thread Display Options. Look for Thread Display Mode and select Linear - Oldest First. Let me know if that helped.

The power curve of this engine is, peak of a very user friendly torque curve, is at 5000 rpm. Horsepower is 7400-7500. Rev limiter is set at 8500, so no need to play with the rev limiter. It protects the engine from things like missed shifts and broken chains. The aftermarket CDI units have not proved out as an improvement, according to several people who have tried them. Maybe someday someone will figure out how to get a smooth advance curve into a CDI, at an affordable price, but not so far. Induction and exhaust is where to start. There is a very good extractor exhaust sold on e-bay for around $120.00 or so. A Mikuni carburetor is the easiest to tune, because of parts availability, such as jets. If you go that route, use only genuine Mikuni jets. Most of the others are not accuratly made....ARH

CG engines are super easy to rebuild, almost as easy as a 2 stroke. Parts are very cheap too.

Not sure how long it's been sitting. I just got it few days ago. Smoke a little when I first drove it. After I changed the oil it smoked a lot worse. Seems like I hear more of a rattle noise in the top end since the oil change. How do you know if valves need adjustment? I've done a plug reading a bunch of times due to messing with needle/mixture screw . Always looks like one side of the plug ( white ceramic part ) is rich and other side lean. What would cause that. If anyone can send a link showing full procedure/specs of setting valves that would be great as I would like to check them regardless. Thx
