i have a lifan 110 motor in my 50 and have not had any problems yet where as my buddies who spent 1500$ on an sdg 110 pit bike have problems with it every time they go out :rotfl:

 

[blmmx]

cool...what about the lifan 125cc???

lifan is a pretty reputable chinese manufacturer. iso9000 certified. quality is generally good. both their 125 and 140 get good reviews for power and quality.

The OGM gets good reviews also though. I don't know the guy that has probelms every time he goes out...maybe he got a lemon. or maybe he's just rough? who knows?

 

[blmmx]

thanks.. :)
what size should i get?
is there a noticable power differance?

 

[blmmx]

thanks for the help. i bought a 125 lifan.

Lifan get's :cool: :cool: from me, one of only two sources I'd ever consider getting engines from. The 140 vs 125 question can really only be answered by price. If there's $100 difference go with the cheaper 125 if there's $50 might as well go for the 140.

 

[blmmx]

it was about $100-$200 difference in price.

Well if it's the same engine (same cases, cylinder, etc...) that's way too high. For that kind of spread I'd be liiking for a inner rotor kit, cam, maybe some larger valves...

and if i ever want to, i can get a 146 big bore kit for it for the same price...$100-$200

If you are looking at a price much over $300-$350 you are paying WAAAAY too much for a 138 (aka 140). Besides think about it, do you really NEED that kind of displacement (I won't say power because it's negligable) in a pit bike? Not really, most 110-125 bikes seem to be plenty fast no matter how fat you are.

im not very fat at all

Welcome to the club! A 107-125 would be plenty.
