Hey yall! From the great Northwest
Hey there. New to the forum. Pretty new to riding in general. I have owned a few dirtbike and quads when I was younger. Nothing really road worthy. Just picked up a new to me 06 lifan 200 gy2. Has around 300 original miles. Needs a few things here an there. Been doing some research on which bikes are interchangeable and what not. But having trouble with finding a front rotor for it. I hear the zongshen gy rotors might work??

Welcome!
Where in the NW are you? I'm just North of Bellingham, across the Canadian border. Do you have dimensions for your rotor?

Welcome; we are glad you joined us.
 Do you have dimensions for the brake rotor itself? If not, can you post a photograph of both sides of the front wheel?

You're lucky to be near Cabela's.

Well good news!
Found a parts bike in Utah somewhere via ebay that had a used front rotor. Not all grooved up like mine. Replaced ut earlier today and took it for a ride. Brakes much smoother now. Tho I feel like I'm getting alot of vibration from the motor. I hear single cyclinder engines when wound up to higher rpm tend to vibrate a bit. Is that true? |

Howdy from one new member to another!
Yes, a non-counterbalanced single cylinder motor will have a good deal of vibration to it. I do not know if the Lafan engine is counter balanced or not. I am sure someone here will chime in on that. Having that been said, even with a balancer, there is always some vibration of various levels due to manufacturing tolerances. In theory I guess if one was to, say, hand build an engine and had the machining work done to an exact specification, a single could be made virtually vibration less. If they did though, one would have a LOT of money tied up in a engine that otherwise sells for $400 new! :-D

The non balanced 163FML engine does vibrate quite a bit while the 163FML-2M (balance shaft engine) vibrates less. Have a look at the engine number to see which you have. One or more loose engine mount bolts will increase the perceived vibration substantially.

Good news on finding a rotor.

Well I do have the 163FML motor. So I'm guessing it has a bit more vibration than most. But I've checked all the bolts and it still seems like there is a bit of vibration. Maybe it needs a valve adjust? tho can they be adjusted? Don't these motors come with a push rod setup?
On a side note I've been looking into a new sprocket setup. Say any recommendations on combonations?? From what I've read on forums and a few locals, running a 15t front and a 46t?? Is pretty common. I'm currently running a 15t front and 54t rear. Has nice low end torque but gutless when you hit 45mph or highter |

Pushrod motors still have valves that require adjustment, and it's a good idea. Show us a pic of the motor, and we'll try to determine if it's a pushrod motor.
