I have a 99 Kodiak 400 4X4 that I picked up for $300. The previous owner had modified the foot shifter by welding a piece of rebar to it so he could hand shift while plowing. As you can imagine, the allows for much more torque on the shifter than it was designed to have, and he broke the stopper off of the the shift mechanism. No big deal, I ordered the part and put it back together, went through the carburetor and off we go, it runs pretty good.
The first thing I noticed is that when I put the shifter all the way down it goes into reverse, I'm supposed to twist a knob to get it to reverse but this seems to be disabled. Also, once in reverse, it's a bugger to get back out. I have to hold the shifter up, then quickly back down and up again to get it to come out. All forward gears work fine, clutch is tight, no problems.
The reverse cable and lever are in tact and seem to move freely.
My question is this: What does one normally have to do to get this thing into reverse? I assume put it in neutral, twist the knob, kick the shifter down. Does the brake need to be applied? I'm not sure what's going on here, I suspect it's been 'modified' as it goes into reverse without the proper precautions, just not sure if the mods were external on internal.
So few months ago I acquired a 01 Explorer 4x4 (think its a 350 but not sure)
Anyway the owner said it started reving very high, shut the key off and still kept running
until finally he shut off fuel and it finally died. During the run away he said the exhaust got
red hot and has melted plastics to prove it. Said some thing flew out the tail pipe, I kinda figured
it was the top of the piston. Anyway finally got around to looking at it (have a lot of other projects in the works)
and checked the compression, Shows about 40 psi. Can hear air coming out the carb while rotating the motor over.
Gonna pull it apart eventually, don't hear any noises or binding in the stroke, You think the piston came apart?
any horror stories of these and is it worth my effort and money? Don't really have any money in it yet. Thoughts? Az
ok help so according the service manual, Idle Air Mix Screw (aka Pilot screw) should be initially set to 2.5 turns out from fully seated.
If I do that the motor doesn't want to start or stay running...right now the pilot screw is probably somewhere near 5 turns out....I'll take the carb off tomorrow to count to know for sure.
mind you the carb got a new float seat,float needle and various other components in the kit.
To get the motor running I hard to turn the pilot screw out quite a bit, and turned the idle speed screw in quite a bit...I didn't hook up an inductive tach to know what it is idling at, but does sound about right.
What should the idle speed adjustment screw initially be set at (the one that has the black cable sheath with a knob you can twist easily)?
Is there a special tool to turn the idle/pilot mix screw whilst the carb is on the running motor? I am using a slotted screw driver bit (normally goes into a driver) by hand..makes it hard to turn the driver and hard to tell how many turns .

Its in pretty rough shape and its gonna be my first atv, I worked on bikes before but nothing to do with quads. Anyways the quad has some problems and im tryna figure out what to focus on first. So the U joints i think are shot. The bike starts first try every time ussually have to give it a lil gas with the throttle and revs right up, idles fine but its running REALLY rich 3 starts and my brand new plug was pitch black
Bike is L model
Its using the original mikuni carb but im not the best at fixing the carbs and wondering if there is anywhere online that would be able to either walk me through it or help me with it i didnt see a air mixture screw so it seems like im gonna half to open it up and adjust like the float and a couple other things

I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE.
when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out
Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
When i try to pull start (push start/roll start) it made a not normal sound and wouldnt stay running.
If my bottom end is blow why would it still turn over fine,
Are my valves siezed or not working properly
or is my timing off causeing valves to not open in correct order with fire
PLEASE HELP all help is appreciated
