So we bought three Kymco quads spring of 2017 and put them through the test all summer in north central WA mountains. My boys MXU 270 surprised the hell out me several times when I thought for sure id have to pull it through some muddy spots but he cruised on though like it was 4 wheel drive(which it isn't). Really a well built great beginner quad even for younger riders as it comes with the restrictor rings that only allow for about 25mph till they are ready for higher speeds which this tops out at about 45mph which is plenty for mountain trails. The wife's MXU450i is about the smoothest running, and shifting quad I have ever been on. Has great pep for a 450 and with on the fly 4x4 she has gotten up every where I've gone(despite my best efforts). She is only 5' tall and really likes the narrower seat on the 450, something to keep in mind if your considering a 500 as that will put you on the wider body which may not be as comfortable a ride for some. I really have only have one complaint about my 700i and that it isn't a 1000 . Super comfortable to ride and plenty of power. Rode these all season with no issues what so ever. To be honest the quality of these machines is definitely comparable to Yamaha, Suzuki, or Arcticat. The main reason I bought these was the price. I was able to score all three for about $14,500 after tax as the dealer had been sitting on them for about a year since no one around here wanted to take a chance on an unknown brand which worked out very well for me. The mxu270 came with decent undercarriage guards and plates but the skid plates on the 450 and 700 are plastic so defiantly replace if your riding in rocky areas. I made mine out of 3/16'' aluminum using the plastic plates that came on them as a template. Only took about $100 and a weekend but you can also buy these if your not a cheap as I am.

Thanks for posting this @domesticated, I really had no idea about the quality of Kymco or if it was comparable to some of the main stream manufacturers on the market. Great pics, they look like fun and well designed ATVs. * Topic moved to Kymco ATV forum.

The coil is a "transformer" in that it steps up the voltage from the system 12v to 10 to 30Kv .It can have voltage on one side with the other switched to ground by the points or electronic circuit. The coil fires by the circuit being broken. The collapsing magnetic field in the primary winding is what creates the voltage pulse in the secondary. Get an old car spark coil and connect it to a battery. Any DC voltage from 6 up will do. Nothing happens until you disconnect the ground. Then you get the spark. That's how all spark circuits work basically whether it is capacitor boosted electronic or a simple coil and breaker point system. I too suspect a broken wire or faulty component, and leaning more to a bad connection since so many new components have been tried.

My friend has a Kymco 700 and loves it.. Yes Kymco quality is right up there with the Japanese makes. In fact , if you dug into it , you'd find Kymco does a lot of manufacturing for other makes , both in parts and assemblies. Some junk does come out of China and other Asian countries, but also despite what American industry tries to tell everyone , some very high quality products do also. Kymco is a Taiwanese company , and their products take no quality back seat to anyone. Now , I can think of some American companies that can't make that claim about their products,f one in the quad manufacturing industry . . LOL. I don't know how common it is on newer ones, but up here among people I know , older Polarises have the nickname " Pull Hairis" for all the problems they have had .

That's great to hear! Keep us posted and good luck. Wonder if the fix is replacing the entire unit or something else.

Update got ahold of Polaris, they said of just a couple of weeks ago they came up with a fix. Emailed dealer who's closed today so hopefully hear something tomorrow. Polaris said to either open a ask Polaris case or tell them they need to reach out to their tech support. So their you have it.
