Slipping but not like the rest...

New guy here! So I’ve read every clutch slip post, not only on this forum, but on the web as well as the dark web and the...light web. My 07 Rincon 680 starts up and you can begin doing wheelies or pulling logs or running over people as quick as you can get it in gear. 5 mins later the clutch starts slipping until a minute or two into it when it finally will not move in any gear forward or reverse. If I let it cool for a few mins the clutch starts to grab a bit but then quickly starts slipping again. Wait a couple hours and it’s back to riding like new...for another 5 mins...
Oil is Gen4 10w-30 direct from Honda and filled just above full mark, The clutch disks and plates are brand new from Honda. The o-rings were still very rubbery and in perfect shape(I know I should have changed them while in there). What gives?!?!

Odd in deed as it seems to be working in reverse order. The engine oil is also the transmission oil. It creates correct pressure when it is thin (hot) and slips mostly when ridden as you do. (Jump on start and go when cold) It takes only a couple minutes to thin enough for good pressure. So firstly, I would recommend you do a pressure test when warmed up. Check each of the 4 ports and see if you in fact are getting the proper pressures. I think you will find an issue with the pump and/or sub trans oil rings , but I am guessing until we see the actual numbers from your test.

Thank you for the response. I did a pressure test, but did not realize that I have no RPM gauge. At idle I have about 40 PSI. I researched and found that the redline is around 6500 and I maxed the pressure gauge(140 PSI) long before maxing out the throttle. Only an assumption, but I feel confident that I have adequate pressure through the main port(page 5-5 in the manual) top front left side of engine. I didn’t do the other ports for lack of rpm gauge...

A little background, I will make this as short as possible.
I bought this used. road for a couple years. last time I rode it I was pulling large branches around my yard to the burn pit. at one point it started slipping as I explained. After tearing down, I assumed the clutch needed to be replaced (clutch disks were at the lower end of thickness spec) because I did sink it a year before(after flushing rode the rest of the day and for another 6 months) The engine never had reverse because the inner case was broken and couldn’t carry the shaft for the reverse gear. I found another engine online and the guy told me the clutch was slipping and needed to be replaced. Engine was clean, strong compression, clutch plates also at bottom of spec range. This is where my original post picks up. So this engine is doing EXACTLY what my other engine was doing. Also the o-rings in the old engine were also in good condition.

I want to start by saying I love my Rincon and I have not had any problems with it. However there are some issues with it that keep coming up. The first was the transmission o-ring problem. Honda should have known better. Then there is the oil pump chain. The pump should have been direct drive as almost every engine they have built has. They could have put a better chain on it and a tensioner to keep it tight. Next was the cam issues. Again Honda should have had better quality control with it. Then there is problems with the connectors to sensors. They get fouled and break. They could have done better. Later on they moved to fuel injection. There has been a lot of problems with that, mostly the fuel pump and filter. However a better move would have been to go to direct injection with a injector screwed into the cylinder head. Honda went from a 650 cc engine to 680, they should have gone to 800 or 900 cc. Also most would agree that the stock tires they put on it are crap. Charge me a little more and put good rubber on it. Most of us had to do that soon after purchase. I know hindsight is 20/20, but Honda has fallen way behind other manufactures with the Rincon class of ATV's. Over the 16 years the Rincon has been out Honda has just not given a dam. It is a shame because the Rincon Platform is great. Honda should have upgraded it into a two seater, gave it a bigger engine and a four speed transmission with a low first gear.

Just my opinion of course.

I have a Moose Feather Pillow and it's great. I should have started a new thread. My brother works at a Honda Dealer and Honda ATV sales are nothing compared to the other Makes. I just wish Honda would step it up.

Update...
Learned that I not only need the one oil pressure gauge, but also a 3 dial gauge at the same time....compounded by the fact that the tach I bought is for 4-6-8 cylinder engines only. About to park it behind the shed and let it rot... Did check the pressures for the transmission and was getting pressure on them...
