Changed oils and clutch may be slipping

Post by Happytrails » Mon Jul 08, 2019 3:59 pm



So I recently switched from Delo 400LE to Mobil 1 synthetic 10w-40 high mileage and I think my clutch may be slipping. When I try slow speed tight turns the bike lurches (is bobbing up and down) turning right or left. It could be something else but my first thought was the oil switch may be causing my clutch to slip. So far it seems fine going straight in any gear. I could be way off with my guess, right now I'm not sure whats causing it but prior to the oil change the bike was fine so that has me guessing the oil could be the issue. Maybe I should try Shell Rotella T6 and replace the filter?

Were you displeased with the Delo 400LE?

I don't know that Mobil 1 is bad or not, but I do know of cases where a switch at higher mileage led to leaks.

I really liked Delo 400LE a lot and still do but I thought it was discontinued? I was concerned about trying a synthetic and having leaks, that happened to my truck.

the Delo 400 is still available, just might not be where you looked.
------------------------------------
Are you using the slipping clutch, foot on brake to control speed, during you slow speed turns? If not, you will find that is much easier to control the bike below ~5 mph. I leave my bike in 2nd gear, clutch in the slippery zone ( never move that lever ), and add throttle a bit so the engine is trying to pull, and control speed with the foot brake.

the synthetic will perform well though, so I would not be concerned about that.

I am using Rotella T6 in my bike, and the clutch action did not change at all.
last year, I used T4, no difference, just the weights are a bit different in T6 for what I wanted.

I just changed my Husqvarna 23hp lawn tractor from 30w non-detergent to Rotella T6 5w40 and it quit using oil :o :o ???

I have run it now about 20 hours and the level on the dipstick has only dropped about 1/4 inch below point it was when I put in the new oil.

Before this last change, I had to add oil every time we used it, roughly 3 hours of mowing... and the synthetic oil is staying clean, the same "see through" status it was when poured in the engine.

and the engine quit puffing smoke!!!
something is "all better now" with the new oil.

Is that oil rated free of friction modifiers?
Did you search here on what oil to use, or did you read your owners manual?

I don't know about that oil, but being high mileage oil it's full of leakstop type chemicals and special stuff to soften gaskets to try and revive them.

Our bikes take special oil due to our wet clutch system. Most random oil on the shelf is a no no. You need to find the specs.

I would post them but I forget, so I look it up when I need to, or I will read my manual if no other options like the internet.

I do believe the round circle on the back of most bottles must have nothing listed in the bottom half, or something like that.

Using oils that are extra slick, or adding additives like my beloved Locus Oil Stabilizer could cause clutch issues.

I have been seeing Delo 400 SLE and XLE at the local stores but not LE so it prompted me to switch. Tried Mobil 1 after reading others on the forums were using it and happy.

I was using the friction zone and a little rear brake just practicing slow tight turns and thats where I noticed it. Just did that oil change and maybe put 30 miles at the most on. I'm wondering if I should seafoam my engine to clean the clutch plates? Or maybe I should just change the oil and see how it does? I think I'm gonna give Rotella T6 a try and see if that agrees with my bike. I wouldn't mind trying Rotella T but I don't know if its in stores near me.

I did jack my bike up and checked the front wheel for anything odd and it seems fine. Looked at the rear wheel and its a little cupped but just the normal that you might expect.

The Delo 400LE HAS been discontinued and its "replacement" is Delo 400SDE which is touted to have equal, or better, results. The 400SDE is working fine in my beast, but I already have Rotella T5 and a new oil filter ready to replace the 400SDE when the time comes. Mileage will dictate when that happens.

My first thought was, , ,when did you last change the clutch fluid, AND, have you ever pulled up that little shiny tab inside the reservoir and run a small "torch-tip" in that hole to make sure its cleaned out. The "return" pressure will build up and cause a clutch to slip badly. There is usually a coating of brown "GUNK" around that area and on the bottom of the reservoir that NEEDS to be cleaned out each time you change the fluid.

That "return" hole would be the quickest and least expensive "potential" solution to your slipping clutch. Then you can move forward from there if it doesn't work. ALL of the suggestions are good ones for sure.

Thanks for the suggestions :)

I change the brake and clutch fluids once a year. Also i replaced or rebuilt most of the clutch hydraulics when i first got my bike maybe 6yrs ago. Even replaced the lines, what a fun job that was. When i change the fluids i like to clean out the return as well. Not going to count that out but the reservoir looked good and I'm hoping the new slave cylinder i installed isnt gummed up yet.

I'm thinking i might change that oil when i get home tonite. Just change it and see how it does. I have another filter and will pick up some oil on the way home from work.

Personally, I'd add Seafoam & run it for a bit, and THEN change it. If there's friction modifiers or other crud on the plates, you want to clean them off before putting in (and contaminating) new oil.

Just my $.02' worth....

Thanks, I was going back and forth on this. I ended up changing the oil and filter just to get the other oil out of there. And I'm going to do a short change (change it again fairly soon) on the new oil I just put in. I'll add some seafoam and try to clean it out as best I can. Reason I did it that way was I figured there would always be a little oil left behind either way. Another lesson learned hopefully. :)

It was supposed to be. I went back and looked at the posts for that stuff and I'm pretty sure I bought what others said was good stuff. It didn't have any friction modifiers listed in the lower half of the API bubble.

The little circle on the back of an oil container should not include the words "Energy Saving", as that would denote the use of friction modifiers that glaze the wet clutch.

https://images.app.goo.gl/ptRBocD3Tj4RY3od9

It occurs to me that the OP used the exact oil as from the DIY section "change your oil" thread.

A clutch outright slipping will be most obvious at maximum torque.

The change in the oil could change the way the clutch engages. Maybe a thousand miles on the oil will help the clutch feel normal again.

Some Bob guy on the internet has a whole forum devoted to the various dinosaur, synthetic, gear, transmission, walrus oils out there if one wanted to get truly technical.

Coming from a "make mine genuine" background, I prefer the factory recommended dinosaur oil in my motorcycle. In the case of the wing I picked up 5 quarts of Honda GN4 dino for the upcoming oil change.

Another point for debate would be that engine oils do not necessarily have the characteristics needed for transmission use.

I only run synthetic oil if Manùal calls for it, or if I truly intend on extending the change intervals.

Just my $.02

Here are photos of the oil I bought and tried. I thought this was what others were using? :o

I've been using exactly that oil in my 1500 for YEARS. It runs extremely well on it, and the transmission shifts very smoothly.

Same here, ever since I read Wingadmins revue on this oil and it has worked great.

Ditto here. I picked this same oil exclusively because of WingAdmin's review.

Thanks for responses that it was the right stuff, I thought I was losing my mind and bought the wrong one. I dont understand why but that was the oil that was giving me clutch slipping problems. I ended up putting in Rotella T6 and the slipping seems to have gone away, I hope! I'll know better after I've had a chance to ride a little more :)
