P500 Third blown engine

I've made living turning wrenches for last 18 years not sure what your referring to as cold sieze. My opinion your a troll or u bought a used one that's been buried in every mud hole this side of the Mississippi.

Cold seize was more common in two strokes but is effectively the piston heating up extremely quick from a cold start and seizing in the jug which takes a little longer to come up to temp.

Effectively start it and rev it wfo until it blows.

I make no claims of being a mechanic but that is my understanding of the term.

Thats called being a idiot lol. Not quite how that works though, the gap in your piston rings keep that from happening. I understand what your saying though, see this more in guys spraying a ton of nox most engine builders call this pinching the rings.

 

[bigshoe]

A dumbass tech that doesn't know what he's doing could just as well not ck the gap on assembly. it would eventually get hot enough to pinch rings and it would blow the piston apart and lock motor up so he might not be completely full of sh**.

This got out of hand quick! I think I’m the only one one this forum (that’s posted about it I think) who’s ran the machine completely out of oil. Like not a drop and still drove for over a mile before she stalled out when I went to shift. A new plug and topped off with oil and she’s still going strong at over 1000 miles later. So yeah, you can say I’m a fanboy.lol. I’ll never buy a different brand of atv/utv now.
Sorry about the problems Fred but it’s got to be something with that dealership and their maintenance? I’d find a new one!

 

[bigshoe]

I agree, I understand a leftover but a 2016 leftover I think dealer doing something sketchy. How many dealers just going to say ill keep the one that blew up here's another.

Bought a 2016 p500 and within 800 km the engine had a “cold seize”. oil changes always done and dealer checked. Dealer fixed it and we agreed that he’d keep the machine, Honda did an extended warranty on it and I got a new one(still 2016). Second machine had the same thing happen at 4850 km. I had it repairedby dealer (new cylinder, piston, rings). Two days ago at 6300 km driving along a road and “baam), huge engine noise and we died. Oil was full and only 300 km old. I always warm it up to operating temps and it was 15C outside. Don’t know what’s wrong but I’m sure it’s not good. WTF? I look after my stuff and am, needless to say, super disappointed. Thoughts?

Question, what fuel is available locally, and what are you running? I'm not familiar with Canadian fuel requirements.

By chance is it 15% or greater ethanol content vs. the 10% in the USA?

Are you putting any fuel additives in due to your climate or for any other reason?

I'm aware these engines occasionally drop a valve, though very infrequently, it happens.

Just seems peculiar that you are having similar failures with multiple machines / engines and that something locally may be contributing to the premature failure.

Still have it, gonna try replacing the angle sensor on days off. I've owned a bunch of Honda stuff as well and was looking at a 3000 watt generator for the camper. Might hold off on that now or try a Yamaha.

Have an electric start ES3000, guessing now 3-4 years old. Use it at our family rustic Fishing Camp and this summer we put in a satellite dish so the missus can work remotely due to Covid-19 so she has worked from here all summer. Runs 18 hours a day plus, have only changed the oil. Has worked flawlessly. Don’t think you could go wrong with a Yamaha either for a gen set. The ES3000 is heavy so installed a wheel kit and is much easier to move now.
Stay Safe.

You know it takes a real piece of garbage to kick someone who's having a tough time. Many of us on this forum have had a lot of trouble with these machines in a short time. This isn't a hockey team that you root for even when their doing poorly, it's an investment with hard earned money. Yet treating people with respect.

I just think the story doesn’t add up, take a look at my other posts in the modifications and other buckets. No pictures of any damage to the motors or parts with damage that many experts here could help comment on. It just doesn’t add up for me.

Actually most people haven’t had problems. And these things are not an investment, they are toys or work tools that deprecate with every use. 3 engines by one owner is extraordinarily rare. Give us something to help.

Do you use mad ramps?

No I haven’t but I’ve used wild ramps their pretty good...😆

Honda's run great with water in the oil. Its something else.

IMO, something far more out of whack than simply a fuel issue to cause such chaos. Very weird situation with three engines, but to give Fred the benefit of the doubt, I would suggest he should have gone to a different dealership/mechanic after the second go around. Seems to me that there is something up there, possibly a loyalty with a mechanic who isn’t qualified to continue working as one. That’s my two cents worth.

We don’t have >10% ethanol Here in our fuel.

Thx. The dealer has two locations with different mechanics. I don’t have much choice for dealers but will use the other location

the dealer is an hour away and I am going in to view the engine.

Not a troll and I live in Canada. Mississippi is a very long way from here, even the upper reaches.

If this guy is being honest then it has to be dealer service issues. Three P5's with blown motors, no way! Poor valve adjustment, wrong oil, something stupid.

Thx for this. Oil has been changed regularly using Honda products. Oil was full and had 300 km on it. Clean as new.
