The engine in this picture is a 120 lifan monstor motor 

that has been bored out to 58 mm, Which makes it a 146cc Psycho Engine.  


  And our Z40 camshaft. 

this head comes with 27mm and 23mm valves compaired to the 

TRX's 23mm and 20mm valves. 

It will hurt you, I found that out.

I'm using this picture just because I was trying to put this in A CT90. THIS AND ANY OF THE ENGINES WE SELL WILL JUST BOLT RIGHT INTO THE TRX90'S..

THE STOCK CARB AND MANIFOLD WILL BOLT ON.

THE CARBS THAT COME WITH THE NEW ENGINES WILL ALSO BOLT TO THE STOCK MANIFOLD.

THE MAIN ISSUES WITH THE TRX90 ENGINE SWAP, IS THE PULL START.

also THE CARB AND INTAKE IF YOU NEED A BIGGER CARB AND MANIFOLD WOULD BE AN ISSUE.

IF YOU WERE TO WANT A Psycho Engine JUST ORDER ONE OF EACH ITEM BELOW....
