The spare I would say is in worse shape than this one. I don't know guys, I'm having a hard time talking the wife into spending what I am, but this sounds like gonna add up pretty fast. I can't say for sure the history, not a bunch of rust anywhere for 20 years old. I would think being sunk would screw up electronics, all looks original. I gotta think hard about this, can get a rebuilt engine for around $1500. I'm stretching my smarts doing what I am without a complete tear down. And labor for doing what I can't will add up $$$ in a hurry. There will be minimal cost doing what I plan on and if I put 30-40 hours a year on it I will be lucky. You regulars here would not bat an eye and can prolly tear down in your sleep. Just not ready for this, and if I end up hearing "I told you so" I will take it like a man......
I sure cannot work on a motors that great, but do know about what can go wrong and odds of them doing so
as for being sunk causing electrical issue's
Honestly, NO is the answer, as most electrical things on an ATV are made toi get wet now and then and most will dry and be OK< minus maybe needing to have connections cleaned and re dielectric greased
its like I said, your this deep in it, I wouldnl;t feel right doing all this work and spending all this money and NOT knowing, or worse, having it all ruined in a VERY short amount of time, be it a few hours of running or weeks!
if done RIGHT, it will last you another 20 plus yrs and more with proper care, since all else you say is good, look at this way,c an you BUY another ATV this clean with a GREAT like new motor for the added costs here to tear it down?
there are TONS of treads and posts about folks that SUNK a atv, flushed a few times and did a NEW top end, and then BOOM< right back to square one, with smoking motor again, and all that $$ down the drain!
its your atv and your $$,and I know we all have a budget
but peace of mind has value too, as well as making a better investment some times, that has to be added to the equation!
the fact this motor is damaged some how, and the old owner ruin a another one before it, says to me, odds are he played hard, and odds are HIGHER he sunk it and sold it when it started to act up!
most GOOD non abusive honda atv owners get 20+ yrs out of a stock motor problem free with basic simple care, the fact he went thru 2??
I know where my money would be going, and if I was a betting man??
I say it went for a swim or MANY!
sorry NOT what you want to hear, but way too common these days with everyone thinking ATV are boats these day's!
