Does anyone have HP, RPM, and torque ratings for the engine that is used in the 192cc 84 though 85 ATC 200X? Any other detailed info would be helpful as well.

Thanks.

 

Here is a quote from Knowsalot. He is by far the most experienced person on here with the 200x. This is from Jan 25th I think.....

"The stock horsepower is 15...which is only 3 less than a 300EX. The 86-87 200X engines were popular for hop up parts in the late 80s, but I don't know who exactly still does them now. Check with Powroll or Fourstroke Tech.

I have an '85 200X engine in a 300EX frame that has everything available in it. It has a +6mm stroker crank from Powroll...a 67mm piston with 12.5:1 ration...XR200 cam...Keihin 26mm carb and intake along with a few other things. It's at 244cc now and that package has consistently been dynoed at 27HP. Alot of people laugh for investing so much in a small engine, but this quad will absolutely destroy a stock 400EX and will stay with a stock Z400 in a drag race."

 

other stuff
9.6 to 1 stock comp.
comp. 156 psi +- 14
bore & stroke 2.56 X 2.28 ( inches)
cam lobe height In 1.2739-1.2802 (in) EX 1.2615-1.2678 (in)

And welcome to the forum! I love the 200X [img]i/expressions/face-icon-small-happy.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img]

 

Is a 200x 2 or 4 valve?
