Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.
Back again with another headache, maybe you guys can help me out.
Picked up a 87 Bayou 300 not running of course, all stator wires melted
on the motor and also no spark. I checked the pick up coil ohmed out good.
traced the wires and led to no cdi box, yes missing. So ordered it and while waited
fixed the stator wires, had to wire direct to harness. Get the cdi installed and after a lot
of other things started it up. Battery dead so used a batt charger to start it. Now when i shut
off the charger the motor died. So i check charging voltage...nada. I see voltage regulator is
old and catalist leaking so i replaced it. Same thing no charge. I check stator and no voltage
with it unpluged from harness while running. Soooooo i replace stator. Now Stator wires have
23v and up to over 50v at higher rpms. So i know its charging now. Connect everything back up and
no charge voltage at battery! Still dies when i shut off charger. All 3 yellow stator wires have good voltage, checked
harness from stator to regulator and is good. The white wire has battery voltage at regulator, the brown wire has battery
voltage at regulator when key on. The Black/yellow stripe has good ground. I get 3 volts at battery when i shut off charger.
If i connect old regulator i get 7 volts when i shut off charger. Do i have a defective new regulator? Im stumped. when i
figure this one out i have a big wiring problem on another one ill let you in on. Az

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'm not getting any spark to the spark plug and I'm not getting any power to the cdi or the stator either need help trying to get this bike going for my dad for the woods any help would be appreciated thanks
Hey all! Im new to the forum and done even have any quads or 3 wheelers... I joined because i am thinking of buying a Honda ATC 125m. It looks like it is in really good shape and according to the owner, it runs great! he says however that the electric start wont work, as well as the light. Im thinking this is a key switch issue. I talked him down to 400 and i want it! but thew downfall is that it is a 2 hour dive down to get it. so a 4-5 hour round trip...
What is a good price for one of these? what are some things to look for if i go look at it? Any suggestions??
What a way to end 2013 ... A friend and I went out for another track ride, the snow conditions were GREAT !! :cheer: ... and we had a blast !!
Only saw two other people & we helped pull one of them out of a snow bank. Better him than us !! :smilielol5c:
We could use more snow, but the ride on this day was AWESOME !! :woot:
I only used 7 of 22 of the video clips I had of the days ride, so there's still some great ride footage on the cutting room floor !! Hope you enjoy what clips or portions of them I did use ... and remember to change the video Quality to 1080p for the best viewing enjoyment !! :seeyac:
