XR200R Lifan 163FML Valve Adjustment Gap Specs and running rich
Hi there.
I'm fairly new to this forum, lurked a bit looking for info, searched and couldn't find the info I wanted. This forum is broken up in a strange way, by type of bike instead of engine manufacturer... Wasn't sure where to post. I have a Lifan motor in an XR200R frame that is having some issues, I thought one of the first things to do is to be sure the valves are in spec. It has 163 FML printed in the side on the lower case. It looks exactly like this With the side port on the top, and the center black with the chrome side covers. Is this the OHV or OHC engine? Can anyone tell me the valve gap for intake and exhaust valves? I have the motion pro tappet tools so I think I can knock this out well... A little about my problem, smoke coming out of the muffler and it won't run with the choke on, since choke makes the mixture richer it makes me think it's running really rich. It has a Keihin PD97A which I think is the stock XR200 carb. I was thinking of getting the valves adjusted and changing the oil and then messing with the carburetor settings. |

I'll set it there, that seems reasonable. It's odd that these engines don't have a manual. I feel like I'm back in the 80s before the internet trying to figure out how to work on my bike by word of mouth. |

Sometimes u need this http://www.ebay.com/itm/231284848909 in repair. OLD floats don't resistant to modern gasohol.

so I cleaned the carb again, put in a rebuild kit and figured out which direction was choke
I play with the idle speed because I realized I was running it with choke on and starting with choke off. I got it going pretty well but it's hard to tell because I don't have a tachometer I have 15/50 gearing which I thought would be good for riding around town but it feels like it's very stressed at 5th gear at normal speeds. Maybe it's just a new bike with new sounds so I just have to get used to it. Does anyone else have one of these motors in a street legal bike? or know of a bike that is made that comes with one? Thanks |

17/46 is pretty good gearing for street and light off road. 15/50 would be too low for me, The motor is likely screaming at 45-50 mph.

Thanks for the input. I think I'll get a 41T to put on the rear. 15/41 is about the same ratio as 17/46 |

I'll either get one of these or look for a Lifan gauge cluster, I would like a neutral light as this bike is for my sister and she's a new rider... |

A size 520, drive chain is much larger than size 428, drive chain.

Every bike I've had has had a 520... Here is a comparison I found a 41T JT steel rear sprocket for 20 dollars so it's not a big deal but good to know. |

Wow; that is a great graphic! How did you get the sprockets to superimpose on each other?

I'll second that. That is a very useful pic for comparing sizes
Looks like he just put all three sprockets on the same shaft and took the pic. Cheers!
