As some of ya'll know, i've came into a couple golden machines ?!. i call them big john, and little john. they are a kwik-way boring bar machines. they are very very old and very very rare to find them , let alone that works ?!. ok..little john works, but needs some shadetree touch to it ?..lol. big john does very well !. i had to bore out a cylinder that came on this stupid trx300ex to a 74.45mm piston. i did get it bored out with the old cutter that came with it, but i did break down and purchase two new cutting tips to go into the holders. one is a rough cut, the other is a fine cut. with some practice, i'll get to make some cash on the side from doing bor jobs, sounds boring eh ?..lol. really though...its getting harder and harder to locate folks that can bore cylinders, let alone cheap, and fast ?. i will not be sending my cylinders out any longer to get bored out. here is a pic of big john, and little john i took today when i was working on this trx300ex.

First thing I'd do is check the condition of the splines on the front prop shaft - the ones near the front of the engine can get stripped, common problem on those older Honda's.

if its making a rattle noise when engine braking ?, this tells me one of the one-way bearings may be bad ?..they wear out over time. as for the bad valve guide ?, you can not tell if its bad just by looking at it ?..it does not show !. i ran across this yrs ago with a trx350 rancher, early model. they left the factory with defective heads is why. the valve guides would be tight on a cold engine, but once started, ran for a few min's..i could blip the throttle, and hear a rattle noise. finding another head was the only fix..no machine shop can solve this..as the head is made for a press fit for the valve guides.

@AKATV will be along shortly. Welcome to ATVHonda!

I've had a Schumacher for a long time. Still works great! Worked on a Rincon for a friend. Wouldn't start due to low voltage and the winch wouldn't retract. Found the positive cable corroded and broken, battery was at 9 volts, and the winch switch also had corrosion in it. Replaced the battery cable, battery, and replaced the switch and winch relay box. Found out the cable was no longer being sold new so I picked up a used one on Ebay.

just guessing, lack of round up ?..lol.
