yimcyco

the choke system has debri in valve prbably need new valveandcable

when the neutral switch don't work the atv wont start

also difficult ti remove

try groung netral switch

all Iremember on those king quad 300 was the revers drive bearing can start siezing

the input shaft to rear diff is stripped where yhe rubberboot is

front diff actator bad

Ive replace 2 in a week already

Ican get on suzukis service tech web site but they canbut there publishing starts at 2000 on servicrepro

choke may be stuck open or thrttle cable sticking

do you see the white lines in the middle of the magnet

sign of bad adherement at 8ac volt you have a seriuos promem

you should have about 20acv at idle and over 50 acv when rpm are incleased

are you check output with stator wires disconnected

check to see if stator is shorting to ground may have pinch wire in backside of stator

if still have problem you need to seek a real machanic

have you check the fly wheel

the old style fly wheel has glued on magnet and they get loose

it works at low rpm but at high rpm the magnets don't turn

this is a common brolem for suzuki atv and motorcyles that use glue on magnet

artic cat has alot of problems with there displays

pin point issue by replacing display with known good one

this will allow you to tell if its a wiring problem or a switch power issue

aiticat had issues with wiring

i just remember having a problem like that from a new unit

turned out to be temp sensor wire shorting to ground as i was

replacing harness

motion pro makes aftermarket cables for all brands

there are 3 basic principles for diognostic

spark/fue/compression

you have ther first 2 now check compression and leak down

that will tell you if the piston is too small for cylinder/need boring

or valve train has a problem

the reading can also signify timing issues

if battery check okay

check ignition and or lightint fuse

the rear brake light switch has a tendency to short out the fuses

from poor design popping fuse killing ignition and dash

if it is replace fuse and disconnect rear brake light switch

th e fi light will always go on when the engine is not running or stall

with that kind of mileage and with a snorkel kit i would consider the condition of the motor

if you found debri in your intake then shouldn't it have gotten in to your motor

fuel injection is very simple if you under stand it

check compression and leak down readings

check valve adjust ment

also check if choke valve system is siezed/stuck

disconnect the plug in from lcd at dash

lcd problem occur when it senses low battery voltage

check float valve assy

and petcock packing it may have torn causing petcocks inability to shut of

packing debtri can also be cught in float valve

what was thevalve clearance set at

did you check for spark rapter has a safety start switch in thottle housing and carb

if thottle is not shut allthe way or switch is not engaged you will have no spark

check valve clearance and make sure carb is clean also check for fouled plug and fuel in oil

running stater too long and not letting it cool down may be starter problem

if you check everything i'd check the flywheel and stator cdi and coil

sound like a bad stator

i would check the fly wheel the magnet can come loose or lose its strength causing eratic running conditions

make sure you disconnect all the wiring and check for corrossion and bad connection befor using grease

check your throttle cable for sticking and gummed up carb slides will hang open causing high rpm

output charging rate should be no less that 13.5v to battery

if not check stator continuity to ground an to each other

no coutinuity to ground and continuity to themselves are good

if okay check stator out put should be around 20 acv at idle and about 75acv at 5000rpm

if good replace regulator

if not good check stator and fly wheel

I 'd check my valve clearance if the carbs are okay and you clean out the pilot circuit and turn the fuel screw out 3 turns after seated then compression spit back throu carbs is stalling it out

also what is your idle set at sse between 1200 and 1500 rpm
