re: Rebuilding Rancher 350 engine

sand the new rings with 320grit sandpaper. Stagger the end gaps on the rings. Use thick oil or assembly lube on wrist pin and a light coat of 2stroke oil on wristpin, rings, and cyl wall. Pour a little oil on valve train befor putting vale cover on.
there is a 8mm headed bolt on the outside of the valve cover(goes in an oil journal), loosen it before starting engine, then remove once running, leave out till you have good oil flowing out of it then reinstall.
use rotella 15-40 in it.
DO NOT OVERFILL it will collapse the rings.
Thats probably what happened when it got water in the oil. It causes to much crankcase pressure, which puts a lot of force on rings and wears them out

I wouldnt used sandpaper, go get a engine cylinder hone from an autoparts store they are about $30.

Unless he knows how to put a good cross hatch on it, hes better off sanding the rings,

I did all of that stuff in the first paragraph and used 15w-40 Rotella. Was gonna drain and refill after 15 minutes of straight running.
IIRC, the valve cover just has four bolts holding it on, and there isn't anything else up there

Slight hi jack.
My 350 rancher started making a good awful squeaking noise from the rear end this evening. I'm thinking wheel bearings. Are those a pain in the arse to change on these bikes?

They can be a pain in the arse on a honda.
The brake drum can be a real pita to get off.
Check your rear differential oil too.
If its not new looking, go ahead and do the bearings in it too. They are prone to get water in them and fail.

Few thousand...um no.
Try under 500 bucks tops.
Id be willing to bet the damage came from running it with milked oil more than anything.
Pull the top end, remove piston, rotate crank to see if bearings are in good shape.
One of the easiest things in the world to work on.
You don't want it? 300 bucks sight unseen.

I take it you mean rodger?
Was one of the most experienced techs in the South until he decided to watch movies instead of fix bikes on the clock. Always felt bad for tbe guy, but he did do it to himself.
He is without a doubt in the top 3 mechanics I know.
To the OP. Ignore the lucas. Run rotella 15w40 or honda gn4. Friendky will pricematch online retailers and you can get fn4 for cheaper than rotella. 10W40 is fine for winter. 20W50 for summer down here.
Side to side movement of the crank is fairly normal with hondas. No other movement allowed.
Just spend the 30 dollars and have the cylinder honed. No reason not to.

If a hunting bike and not taken on long long rides... There's an easy trick.
Tap the brake drum and install a grease fotting. Do the same thing on the fill plug for the diff.
Pump both completely full of grease. Thw brakes will still work fine. The diff bearings and seals will NEVER go out again. Use quality grease and put a few pumps of clean grease in occasionally.

I'm definitely going to change them. Just called the Honda dealership and they aren't but $30
Posted on 4/4/15 at 7:20 pm to KingRanch
All back together and ready to rumble......but I lost the mother fricking key
Eta: Found the key. It sounds like it's not getting enough fuel, and knocking a little bit. Time for some carb work and we'll see from there

Tell me about it. I had to do this last year on my 1990 fourtrax. Here's what I came up with and it worked
Posted on 4/4/15 at 9:09 pm to weadjust
Great thread. Keep updating. I'm looking for a few used bikes to take kids out with. Maybe I can add one now and one later. The old fourtraxx are boss. Are there any other makers worth it at a decent price? Maybe the old bayou?

Got the new carb in and it is running perfectly right now. Only problems are a little bit of smoke (smells like burning carbon, not oil), and it is knocking a little bit.
Starts, idles, and revs up like it should though, but I'm stumped on the knocking and am not sure if the smoke is from the exhaust being caked with carbon on the inside

I have to say I'm impressed at how far you have gotten that thing along.
Posted on 4/15/15 at 10:17 pm to Me4Heisman
So far I've only spent $163 on it, and it drives like normal now. Wish I could figure this last shite out though because I know it'll frick up worse further down the line.
I need greasemonkey to drive to Metairie one day

Update again:
Started it and let it run for 10 minutes at lunch, and there was ZERO smoke coming out of the exhaust. Only smelled like burnt gasoline like normal. Engine still rattled a little bit, but not as much as yesterday. Screwdriver test says the valves need adjusting, so I'm hoping that's it.
This mother fricker has me scratching my head
