Folks, I am new to ATV world and recently sank my rancher(2015 DCT EPS 4x4) into a river(no excuse, a boneheaded mistake). Long story short, got water into the engine but manage to fix it by flushing pretty much all the fluids and changing all the filters). The engine runs normal now(thank goodness). However, there is a new issue: when I put on gears, either D or R, the vehicle start to get really jerky, feels like it's trying to jump forward/backward. But if I let the brake go and give it a little gas, it will run smooth again. Any clue what is going on, and how to fix it? Thanks in advance!

Of course, I understand -- the oil I used is "Honda Pro Honda GN4 Motor Oil - 10W30", this is the only oil I've ever put into the engine. Thanks!

What oil for the engine are you running? Exactly, what make and weight? Since you are new, please understand that your bike has a wet clutch that cannot tolerate just any old oil on the shelf. If the oil is not "JASO MA" rated for wet clutches, you could have just trashed the friction disks in your clutch pack.

Thank you, I did research quite extensively on how to rescue the water damaged ATV. And I did everything within my mechanic capability to do so. So far the machine idles normal, sounds normal and no smoke or anything. It drives normal as well except what I described in the post.
If this is indeed something more serious and need real mechanic work, I will take it to the shop for sure. I just hope this jerky "condition" is something can be adjusted quite easily so I can save some money. Thanks again for your input!

hate to tell you, but flushing a motor doesn't fix damages done or to be done, its like buying a lottery ticket, some times you win, MOST times you loose!
do a search on any ATV forum about ATV soon smoking after sinking and flushing motor????
Fingers crossed for you, but heads up!
I;'d do a compression test NOW get a base line and check down the road!

as for possible issue?
maybe the new brain on this thing got wet and needs a re flash from dealer, water does silly things to things!
Just an idea??

Thank you sir, I think I am just gonna quit messing it around anymore and just send it to the shop. I appreciate your input!

the deal with sinking a motor is this, dirt and crap come into motor with water
its IMPOSSIBLE to get ALL that all out flushing the motor
your motor may run and idle fine and NOT smoke right NOW
but down the road the crap left inside can eat away things and as time goes by, you will end up with a bigger repair on your hands
LIKE I said, its like a lottery ticket, some times you get LUCKY and never have issue
s some times you DON"T

as I suggested, DO a compression test NOW< to get a number
check in 20-25 hrs and see if its dropping, if NOT, check again in another 25-30 hrs

if it is then dropping?
, your going to be in for motor work, from what was left inside the motor from sinking it
its simple to do a compression test, if you don';t have a tool to do so, MOST chain auto parts store will loan you one for FREE< just give a deposit, and then get deposit back when you return it!

its a GOOD idea if you ask me, then you know where your headed or NOT

damage to a motor can happen SLOW or FAST< all comes down to HOW Much crap got in and how much got OUT

NOT trying to scare you, just offering you some advice and info, and a way to keep track of things to see whats going on!

Hey guys, I had my rancher back today. Turned out the problem is my IACV didn't get installed correctly(I uninstall it earlier). They did other tests and everything is fine. Cost me 90 bucks for the diagnosis and stuff. Good to go now! Thank you all for the input!

Yeah, I am pretty sure I didn't get any dirt in it. I sank in clean water, not in the mud. All the filters were clean when I took them out. But I replaced them anyway. The Honda dealer told me they tested the engine and everything is fine so I guess I am fine. I rather spend time on having fun rather than worrying about it.

Hey rocktd, I've sunk many bikes in the past and rode with others who did too. Not once did I get dirt in the engine. I know for a fact that it can but I don't know the details. I think the details are important too. In other words, I know for a fact that sinking does not equal dirt in the engine.
