500 motor in quad??

<< < (5/5)

3Razors:
The problem is there is very few good examples of LT500's running around.  Most have been hammer'd on and worn out and with the factory flaws its a bad combo.  On the LT5's especially the 87 you have to fix the factory flaws before any performance work is done which includes o-ringing the head, brass or steel inserts for the crank bearings, billet thrust washers for the piston, getting a 88-on flywheel, and if serious porting is done welding up the rear cylinder ear mounts.  If you do those things the LT5 is stone ax reliable.   

Both the LT and KX motors are similiar in that they have the same bore/stroke.  The KX has a better port layout but the LT can lay down some serious hp too when done right.
