Hey guys i've decited to do a "How To" Write up on rebuild the top end on a Honda Rancher
The Gas Tank And Front Plastic and air fliter housing, carburetor and Exhaust Must Be Removed For This.
1. Remove the following upper hanger bolts and nut hanger bracket and mounting rubbers
Now You Can remove the following four head bolts and head cover
Next Remove the following Timing Hole Cap (by foot brake pedal right side) Now Rotate the crankshaft clockwise using the recoil starter knob to align the T mark on the flywheel with the index mark on the rear crankcase cover.
Make sure the piston is TDC (Top Dead Center) on the compression stroke.
This position can be obtained by confirming that there is slack in the rocker arm. If there is no slack, it is because the piston is moving through the exhaust stroke to TDC. Rotate the crankshaft one full turn andmatch up the Tmark again.
Now Remove the following spark plug cap,sparkplug , rocker arm bolt the four cap nuts and washers(Loosen in a crisscross patter in 2 or 3 steps) and the two 6mm bolts. then remove the rocker arm.
next you need to remove the two push rods(they just pull out)
Now its Time To remove the cylinder head start by gently taping the cylinder head with a hammer to loosen the seal( Do not strike the cylinder head too hard) once it is loosened it will come right off(straight up).Now it will look like this. next you need to remove the two dowel pins and gasket(just pulls off) .

Now remove the gasket and two dowel pins.
Next Place a clean shop towel over the crankcase to prevent the clip from falling into the crankcase. Remove the piston pin clips(one on each side) with the pliers. Push the piston pin out of the piston and connecting rod, and remove the piston.
I will get the rest later today.
