I know this is a automotive site but I just want to see what you guys think.

 

On my xr 650r dirtbike it feels to me like the clutch is slipping. The RPMs go up but the bike doesn't seem to be pulling as hard as it should. I tried adjusting the clutch and adjusted it to the manuals specs which seemed to help a little but it still doesn't feel right and with it adjusted in spec the bike rolls in gear with the clutch in. When accelerating if feels like the gears are really close together and I'm thinking its probably the clutch plates what do you guys think?

So it's the new version of the 650 :thumbs: A friend has one and that thing is a rocket.Shouldn't be too hard to change,just be carefull when tightening the four bolts on the clutch pressure plate.When I do mine I lay the bike on it's side so I don't have to drain the oil....and I always soak the friction plates in oil for a while before I install them.I've done clutches on older bikes I would assume they'd be the same or similar on your 650.

Well I soaked em for about 2 hours and put them in, the bikes a whole new animal I didn't realize they were that bad! However my problem is now that the plates seem to stick together and I can't seem to get the clutch to disengage all the way

Try tightening the cable a little,but always leave a little play when the lever is fully released.The metal & fiber discs are new and should loosen up after a couple of rides.At least that's the case in my experience.Nothing like a new clutch after dealing with an old slipping one :thumbs:

Well I had to adjust it all the way to get any clutch action at all. But I'm going to look at it some more to, I was getting frustrated yesterday and had to take a break before I started breaking things.

Well I found out there is a slightly smaller friction plate that goes on the judder set up. So I fixed that. But it didn't make a difference I'm still checking things out though and I started with a friction steel friction steel and so on. The is the same number in the new pack that was in the original one.

Ok so if I pull the clutch lever with the cover off it looks like it seperates the outer plates but not the inside ones I can spread them with a screw driver gently. Also to get any clutch action I had to adjust it all the way to get the clutch to engage at all other wise it was just a loose lever. And also now it chatters with the clutch all the way pulled in which can't be good.

You might need a new basket, you check for grooves or any sort of wear and tear?

Just to review the number & sequence of the discs & plates....the first one to go in is a friction plate,then a clutch disc(the metal ones),then another friction plate etc.So the first and last one is a friction plate and there are one more friction plates than clutch discs....is that what you have?

 

Don't know how many your 650 has but my XR600 has seven friction plates and six clutch discs.

 

Do you have a repair manual for this bike?All this should be in there.

Yep I went friction first. And it seems like I had 7 fractions and 6 metals. I double checked to make sure I hadn't lost any parts http://www.rockymountainatvmc.com/oem-schematic/8

 

And used this as a guideline.

But I didn't do the bearing or any of the other mods.

 

I'm starting to wonder if my clutch cable isn't stretched out to where it doesn't have enough pull to spread the plates. Because I have it adjusted to give the cable all the pull it can and its still not spreading them out all the way.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      I found a setup that lets me open the cover partway with racks installed, using side-rail-mounted systems for easy access.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
