I recently purchased a BMX 150cc ATV and I am trying to find out what engine is on it. The carburator is made by Sheng Wey and it is shaft driven, not chain. I am also trying to find out the valve clearance for this engine. Any help would be appriciated.

 

Is it a "BMX 150" or a "BamX 150"? Ive never heard of BMX, but BamX is up in Gridley, Ca. If you have a BamX, the motor is made by Tomoto, China. The fella that owns BamX visits this forum occasionally.

 

It's BMX not Bamx. I think these just recently started selling in the USA.

 

does it have an cvt transmission? if it does ,chances are it's a honda gy6 clone.

 

It has the manual 5 speed transmission. Here is a link to the website that sells them and the one I have, but it's like pulling teeth to get them to give you any information or specs about them. I looked at other Chinese brands and the only other engines that look like these say they are 200cc.

Thanks for the help.

 

Welcome to the forum masterbs, I would assume its a Honda copy. Who copied it in china is a good question thats for sure. How do you like it? I would set the vlaves at .002 stone cold. That has worked for my Yamoto and is the spec. for all my Hondas.

 

Thanks mywifesquad! That did the trick and the quad is running just fine now. I did find out that these quads use an engine made by Lifan.
