Mar 11, 2008 · The 26 Mikuni that came on my OGM (YX) 150 seems to work beautifully. Nice power everywhere and no flat spots or blubbering. I like how it runs with the IRK so far, but I do have a Reeg rotor weight coming just to see how a few more ounces of flywheel feels like. Honestly, I am really glad I got the Mikuni carb on there.

Apr 4, 2008 · the Yx and OGM 150 Motors both Have KLX Topends (Heads & Cylinders) which allow for KLX110 motor parts from aftermarket companys as Kitaco,Takegawa,Trailbikes and BBR will fit. KLx110. As of this moment a KLx110 style China Motor is not availible for a KLx110 Frame and these Yx 150cc and OGM 150cc motors will not fit or work in a KLx110 bike

Oct 1, 2009 · Just thought I would share some info here: Bike: 2008 Pitster Pro X4 Motard (street-legal) with a YX150 engine and 26mm Mikuni carb, bought brand-new. Used Shell Rotella T synthetic for the first 1000 miles, then switched to Valvoline 10w30 Syn Power full synthetic for the rest. The Valvoline see...

Mar 22, 2008 · Killer motor sports.com dominator bike says it has 13.8 HP. They have a 32MM Mikuni carb on there but dang. My OGM YX 150 is suppose to only have 11Hp and it freaking rips! Wonder where they are getting the extra HP at or from? Looks like a great bike too! Anyone know anything about it?

Mar 11, 2008 · I love my OGM YX 150 engine, but for a fun, torquey and reliable engine, I really, really like my OGM Lifan Monster 140. It's not as fast, and doesn't have the horsepower potential of the YX but it is as smooth as silk and is just fun and easy to ride. I have to say that the pitster posse has been EXTREMELY aggressive here on this forum lately.

Nov 7, 2008 · Know one was carrying YX internal parts yet because it was a new motor, new bike, so it was a pain finding one but like I said I finally found one from "pitster pro" Thank you pitstser pro. So now it’s been a wile since I ripped apart the case and gutted everything from it. I have everything lined up and ready to be put back together.

Oct 8, 2008 · Hey guys, I have a Pitster X4 with the YX150 engine and genuine Mikuni VM26 carb. Just thought I would post some helpful info on my carb settigs. Engine is bone stock with the stock foam filter on the carb. I am at about 500 ft above sea level, normally very low humidity. I think I have the main ...

Dec 6, 2014 · Hello, I have a new 150 YX and I received today an OKO 28 carburetor. Before to install it I did disassembly it for deep cleaning and I had to reset the float level. The carb comes with 2 extra sets of main and idle jets but none of them have size # on it. The bike start and idle good but doesn't...

Aug 19, 2014 · I recently bought a chinese motorbike (not a pit bike because it has 14/17 wheels) with a yx 150 motor in it, but the motor looks exactly the same as the yx 140, but on the side of the cylinder it says 150ccm. I read in an old thread that the same motor was badged 150 but was actually a 140. It was a 3 year old thread. But the bike rips! Cheers ...

Mar 19, 2009 · If I remember correctly some of the Earlier (OGM Yx 150 Motors) had a slightly different Honda crf 50 style exhaust port design on there heads and GPX Yx 150 motors had the KLX 110 exhaust port design on there motors...they look the same but the port angles are different. there is a fix a exhaust adaptor that corrects it.
