Someday I will find a basket case 89-04 engine for a decent price and re-build/mod it and then pull the 87 out and sell it.

my 86 engine makes it easily :-D ... sometimes its hard to keep the frontwheel down... but always in the middle of powerband. by hard revs it gets a little bit powerless on the top, because the rotating masses. maybe you need a little bit pipe-change for more bottom to midrange power and i think, after that you need frontweights of a tractor to hold your frontwheels on the ground... 8-)
but i have to say i use the shorter second gear of the 89-2004 k5 engines :mrgreen:
Goat:
Anyone know if the newer 90-04 flywheel and stator will fit the old 87? I'd also like to put a cheap lighting coil in as well so I can run the same LED headlights I did on the KDX quad. They work great and are brighter than any other lights I've had on any of my toys over the years.

if you replace the complete ignition (stator and cdi) it will work like you want. the 86-88 and 89-2004 bottom ends are very similar except some little details that was changed over the years...

That's what I thought but wanted to make sure. I'll start keeping an eye out for a newer setup on ebay. Thank you Motopunk

:-)... and with the bigger flywheel it will add a little bit torque to the engine ...
