Mikuni is actually a Japanese company. China can produce some junk parts , but unfortunately so can Canada and the US. China is also capable of producing some very high quality products , and if you look closely you'll find an uncomfortably large number of "American" or "Canadian" products containing some Chinese made parts in their makeup. Dismissing any countries products as junk out of hand is foolishness in the extreme. As far as carburettors are concerned, unless it is corroded badly, very few actually need to be replaced.. They all can be cleaned but attention to detail is needed to get every passage and port / jet cleaned and unplugged . .Too often tiny holes in jet tubes and carb throats are missed. The only carbs I've ever seen that needed replaced were some on such things as weed eaters where the carb is plastic with some jets and parts non serviceable and plugged from being unused too long with old gas in them .

Screw in to lean , out to enrich. Most carbs are set to 1 1/2 to 2 turns out from lightly seated. adjust in and out about a 1/4 turn at a time to find the sweet spot where it idles good ( usually just below max idle when warm) and doesn't stumble when you go to accelerate .

I don't think rings are the problem. I've seen some pretty worn out motors start right up without a problem.. My guess is it is either running a little too lean or the choke isn't working. Cold motors need a richer fuel mixture to start. That's why most carbs have a choke, either manual or automatic, or a lever to enrichen the mixture and fuel injection motors have a start enrichening cycle for cold motors

Glad you finally got it . I would never have blamed the CDI being wired wrong.. LOL. usually wire electronics wrong and they don't work period and often all the magic smoke leaks out

If it is the winch relay just remove the two activation wires at the relay and see if there is still the loud click on connecting the battery.. Disconnecting the power to the relay doesn't stop the relay solenoid from firing since it is connected to ignition switch power.

Yes, the only adjustment on most carbs is the idle air screw. It mainly allows proper idling and when set right stops the motor from stumbling when you go to accelerate . If you will be regularly running at those altitudes you would need help to re-jet your carb. If it is just for a short time , I wouldn't bother with the re-jetting. You'll lose some power (18-20%) but unless you're into full bore running you'll hardly notice it . The worst you might notice is idle and stumbling off idle and that can be remedied by the air screw adjustment and that setting is likely only to need about a 1/4 turn from where it is now. The idle air screw is likely to be the only thing on your carb to have a thumb screw for adjustment. It is normally only about 1 1/2 to 2 turns out from seated.

You should be able to clean all the jets and passages in your carb. You should not need a new one unless that one is seriously corroded.. Stalling on giving it the gas is usually a lean burn problem caused by air bleed screw misadjustment or a plugged and overlooked jet or missed hole in one of the fuel tubes. There are some really tiny ones easy to miss. If there is an acceleration pump to give it a momentary shot of gas that could also be faulty. Those are all the fuel side. The other thing is ignition breakdown when combustion chamber pressures jump with the throttle moved off idle. Do you have a spark checker to see if the spark is still good when you hit the throttle ? If spark disappears when you do you know the problem is in the ignition circuit. If you don't see any hesitation in the spark give that carb another tear down and very close inspection. You need an exploded view of that carb to see where everything goes and look for overlooked screws , like some carbs have .. Some carbs have both an air bleed screw and an unnoticed fuel screw as was noted in another thread on another machine .If it runs at idle and stalls on acceleration it is fuel or spark. Fuel is the most common problem . I'm taking it for granted you have a new properly gapped plug and a new plug wire.

Glad your transmission is ok. It's a lot cheaper changing out a differential from a wrecker. UI know the feeling. Years ago I thought my transmission or transfer case had gone on my 4x4 and it turned out to be the differential that time too. Mine started with a bang and crunch and then got progressively worse until I got it to the shop.. by the time I got it there there wasn't much left of the differential gears

Power loss in carburetted engines is about 3% for each 1000 ft. of altitude. You would need to lean our you engine a little for those altitudes to keep it from running too rich.

I added a pdf of the wiring of the various connectors used in vehicle socket and trailer plug wiring to the "Other ATV files" section in downloads.

Transmission is most likely toast . If the linkage was fine the tranny will need to be opened up, and dark burnt smelling fluid is a huge indicator of a dead transmission. Changing fluid will do no good and just be a waste of money.

The input shaft is what transfers the power from the engine through the torque converter to the transmission gears. I doubt it broke. I have no idea what MLPS is supposed to be. There's a number of things could have gone wrong, from the linkage from the shifter to the trans becoming disconnected to the failure of the oil pressure pump in the transmission or something in the valve body and solenoids that select the gears .

I doubt the lack of coolant affected the transmission.. Most transmissions can be run a long time with the coolant lines blocked off unless they're being run under very heavy load. The lack of coolant would have seized the motor long before it hurt the tranny.

Members like @Rich don't realize how close Canada and the US are tied with citizens of both countries having relatives on both sides of the border and the integration of many of our businesses. I have no vote in your elections , but I do have my opinions which are just as relevant as yours. If the US only dealt with her own with no trade with the rest of the world maybe world opinion of what goes on there would not matter , but with the US being a major trading partner with so many, their opinions matter and directly affect your trade with them. Ask your farmers and others hurting because of tRumps asinine tariff war if other countries and peoples opinions matter in American affairs.

Justrandy , the UK can easily replace Boris if he riles the masses enough. They don't even need to go to the polls to do it. I believe there are some differences in their Parliament so I can't comment on exactly how they can do it , whether it is like ours where his party merely has to hold a convention and choose a new leader or if it has to be a choice by all members of Parliament. Our income tax rates are on a sliding scale. Copied this direct from the government site : These taxes are after all our personal deductions have come off our gross income , rate is on net. Federal tax rates for 2019 15% on the first $47,630 of taxable income, plus 20.5% on the next $47,629 of taxable income (on the portion of taxable income over 47,630 up to $95,259), plus 26% on the next $52,408 of taxable income (on the portion of taxable income over $95,259 up to $147,667), plus 29% on the next $62,704 of taxable income (on the portion of taxable income over 147,667 up to $210,371), plus 33% of taxable income over $210,371 Unfortunately I don't qualify for getting hit with any of the four top tax rates. Federal business taxes are nowhere near the rates you quote either . If you want to make your head spin here is the government noise on corporate tax rates: https://www.taxtips.ca/smallbusiness/corporatetax/corporate-tax-rates-2019.htm I suggest a good stiff beverage of your choice as you try to make sense of it. Federal sales tax is 5% on nearly all goods and services. Provincial sales taxes vary by province . Here in BC it is 7 %.

I hope not .. It would cost a fortune for the wall we would make you erect and pay for to keep him in, and to support the armed guards we would need to make sure he didn't climb over or tunnel under. We have our own much milder version of tRump here seeking election. We don't need the full blown one here . Maybe Boris would welcome in the UK.

As long as our discussions bring others to thinking and searching for facts , real facts, and forming their own opinions we have accomplished something. We may not agree on everything. What a boring world that would make , but we can civilly disagree and reach a consensus that benefits us all. If only we were all as smart as the Great Orange one claims to be

Trump, or as I normally spell it tRump to refrain from being accused of profanity, is the perfect example of a cult leader. His followers blindly follow him and ignore every negative fact of his suitability for the position. Clinton was the target of character assassination for years before she ran for the presidency. The lies and half truths against her were repeated often enough over a long enough period even skeptics developed a dislike for her. It's unfortunate because she would have been hands down a far superior President than the present disaster to the US. The only thing I had against Hillary is that she was more hawkish than I like to see, but whether you agree or not , I saw her administration skills and intelligence first rate . Rump has a BS degree in economics.. The BS is very fitting and doesn't mean Bachelor of Science. I wonder how much Daddy paid for little Donald's degree. The GOP can be very glad the rest of the world can't vote in American elections .. They would be totally wiped out for their support of tRump. Only in America could he stay in power without a shooting uprising .. In the Parliamentary democratic countries he would have been removed from power long ago by his own party members simply by voting in a new leader .. You in the US have far less ability to easily remove him.. There is no "redo" provisions for your vote for President when corruption and interference swaying the election has been so strongly shown, even if technically not proven in court yet . Getting rid of the anachronistic Electoral college would go a long way to bringing the US voting system of of the 1700s into modern reality of communications .. It served its purpose back then when It sometimes took months to tabulate votes and relay results to decide the Presidency and members of Congress, but now it is really useless and can result in the wrong person being elected simply because he ( or she) took the majority in key states. The US surviving tRump so long without violence and collapse is a tribute to the innate strength of the American economy and the majority of her people. I wouldn't test it for another 4 years though.. You've been lucky so far .

I bought my '91 300 Fourtrax FW about 10 years ago and the only repairs I've had to do to it is new front brake shoes and a new rear axle and hubs .The axle was pretty much toast when I bought it but ran it for about 5 years before the splines on the left side finally completely gave out so in effect if I had traction ok on the front I had 3 wheel drive and if not I had one wheel drive LOL. Yup turned 76 6 days ago. I still think I'm 30 until I try to do what I did at 30. Takes me a lot longer and I need a lot more help to do it now, and I hurt a lot more afterward I rode dirt bike and drove standard tranny cars and trucks for years so definitely familiar with downshifting .. Both my Blazer ZR2 and Sierra 2500 HD are automatics now so the quad is the only manual shift. Didn't ride quads until I bought the Honda so I definitely was a late starter on them .

I am also a Honda man because when you're deep in the woods you want the machine that got you there to get you back. At 76 I don't need the fastest or the most powerful and pretty looking .. I want a machine that does everything I want it to do and doesn't need a warehouse full of spare parts to keep doing it, and I might add one that doesn't eat up my pension funds to keep going .

Since Kawasaki doesn't give the size and pitch of the bolts, I would suggest estimating the diameter of them and then go to a metric bolt supplier and buy one bolt of each that appears the same size. Get one of each pitch if there is a fine and coarse pitch offering in that size. Here is a conversion chart of common inch bolts and their standard metric equivalent. I'll add it to the downloads section also.

an't fight you on that .. My own quad is a 1991 Fourtrax 300FW. Does everything I want . Bought used 6 years ago.. Only repair I've needed to do on it is replace the rear axle due to worn out splines at the hubs. and replace front brake shoes. Still runs strong and not burning oil. Yamaha, Suzuki and Kawasaki are also all good machines ; as well as the Kymco machines.. I know some swear by Polaris but around here most swear at the older ones ..They're nicknamed "Pullhairis" by the ones I know that have had one in the past . I don't know how the newer ones are because nobody I know has one ..
