You are very observant, Mike. Indeed, my Primary Drive, rear sprocket is very worn, and I plan to replace it in the near future. Spud
I started replacing both my sprockets and my drive chain this evening, but I ran out of light, Mike. I will finish the job tomorrow with the following parts: XR650R, 14-tooth, Primary Drive countershaft sprocket XR650L, 48-tooth, Primary Drive rear sprocket RK 520EXW drive chain, 110-links Spud
Several days ago I installed a new drive chain, and new sprockets. Therefore, I took the opportunity to inspect my chain rollers. Here is a photograph of my chain slipper roller after 10,600 miles of wear. Here is a view of my mounting hardware, and the port side of my single Spud Roller after 5,700 miles of total wear, and 600 miles of wear as the solo roller in my chain guide. Here is a top view of my single Spud Roller after 5,700 miles of total wear, and 600 miles of wear as the solo roller in my chain guide. When I installed my new drive chain, I switched from a 13T/45T sprocket combination to a 14T/48T sprocket combination. Since the larger rear sprocket has lowered the bottom of my drive chain, I am glad I switched to a single Spud Roller. The single, forward roller allows more clearance from the rear sprocket, and facilitates removal of the rear wheel, et cetera. Spud
It seems that the location of the chain slipper roller is optimal. I looked down at mine while riding and noticed that the chain doesn't even touch it half the time which probably explains the very minimal wear; yet I haven't seen any chain-to-frame contact in that area so it seems to be about 100x better than the OE slipper Mike B
I agree, Mike. After riding with this chain slipper roller for over 10,600 miles, I have noticed the drive chain seems to merely, lightly tap this roller. This chain roller only cost me $10, and at the present rate of wear it might outlast most of the motorcycle. Unlike the stock "chain slipper," which wears quickly, and needs to be removed to be inspected, this chain roller is very easy to inspect for wear, and proper operation. The surface of the roller is easily visible for convenient inspection, and you can quickly spin the roller to ensure its operating properly. The mounting hardware is also very easy to inspect. Just give a tug on the nyloc nut to ensure it's still tight. I have never had this chain roller loosen on me in over 10,600 miles of riding. As you noted, the drive chain never touches the frame, so the roller is performing its job superbly. The only downside to this chain roller is a slight increase in noise from the drive chain as it intermittently, lightly taps the roller. The stock chain slipper costs about $14, plus shipping, and it wears much faster than this chain roller. Incidentally, I think all the commercial chain rollers need more grease in the bearings, even when they are brand new. I didn't grease this roller before I installed it, but I wish I had. Here is a photo of the original grease left in the bearing after 5,000 miles of wear. Therefore, I recommend that XR650L owners grease the bearings before they install this roller, and add new grease to the bearings once a year. Spud
I'm pleased to report my single Spud Roller is performing very well in my chain guide. Here is a photograph of the port side of my Spud Roller after 7,200 miles of total wear, and 2,100 miles of solo wear in my chain guide. Here is a photo of the top view of my Spud Roller after 7,200 miles of total wear, and 2,100 miles of solo wear in my chain guide. Chain rollers offer several advantages over chain sliders. 1) The open, bottom end of the chain guide collects less dirt and mud with a chain roller, rather than a chain slider. 2) The rotating chain roller induces less friction on the drive chain than a chain slider. 3) My Spud Rollers are less expensive than the OEM chain slider. 4) My Spud Rollers appear to wear longer than the OEM chain slider, especially in dirty, or muddy environments. 5) A chain roller is easier to inspect for wear, and therefore requires less maintenance than the OEM chain slider. To be fair, a possible disadvantage of chain rollers is they produce more noise than the OEM chain slider. However, as my Spud Roller "breaks in" after 7,200 miles of use, I'm pleased to report it is becoming much quieter. If you are interested in purchasing either a single Spud Roller, or a pair of Spud Rollers, please refer to my thread in the Vendors Forum. http://www.advrider.com/forums/showthread.php?t=694545 Spud
Hey Spudman! How's it going? I'm finally getting around to replacing the shift shaft in my XRL - what a job! In looking for further trouble, I've found the swingarm slider and chain slipper about shot. I was thinking of a slipper roller as in your mod here, so I came checking your thread trying to find a specific part to order. I went to find the part as you said for a 2000 XR650R and it shows that bike using the same static slipper as the XRL. The XR400R DOES use a roller there but it doesn't specify what diameter. Is that the part for the front roller to use? (52158-HC0-000 ROLLER, CHAIN $8.76 $7.71 In-Stock) My rear slider looks plenty serviceable yet so I don't plan to mess with that yet. Thanks!
Please excuse my belated response, Islano. I guess my notifications were turned off for this thread. I only own an XR650L, so I can't verify the chain rollers will fit other Honda XR models. Spud
It's good to hear from you, OnO! I replaced my "chain slipper" with a Primary Drive, lower chain roller designed for the 2000, Honda XR600R. This chain roller is 38 mm in diameter. I purchased the Primary Drive chain roller from Rocky Mountain ATV/MC. http://www.rockymountainatvmc.com/p...Drive-Chain-Roller/PRIMARY+DRIVE+CHAIN+ROLLER Spud
Thanks Spud! Rocky Mountain must be in error. When I brought up the above link, it says: 1096220001 Primary Drive Chain Roller Large 38 mm Black Fits: Honda XR600R 19902000 $9.99 1096220001 Primary Drive Chain Roller Large 38 mm Black Fits: Honda XR650R 20002007 $9.99 However, when I look at the fische for the 2000, Honda XR600R, I don't see it. I see the static slipper - #7 Which is why I couldn't find a Honda part number. I appreciate you getting back to me Spud-man as now I have a MFG (Primary Drive) and a part no. (1096220001). I was about to order one for an XR400R - problem is (if I can believe what I'm reading in Rocky Mountain), that's a 31mm wheel (instead of 38mm which you have vetted for our XRLs): 096220004 Primary Drive Chain Roller Small 31 mm Black Fits: Honda XR400R 19962004 $9.99 I may have to cross something else to the primary drive number in order to get all my parts from the same vendor. We'll see... (I'll let you know) Always a pleasure! Best wishes!
That's interesting. :huh Oh well, just order the Primary Drive chain roller I mentioned. Don't worry about the Honda parts compatibility. That Primary Drive chain roller will work perfectly for you. Spud
I'm withya Spudman. The reason the "parts compatibility" was important to me is that where I was ordering from, they don't carry Primary Drive, and the ones they do carry aren't specifying the diameters, they are just chosen by bike model, so I needed a bike that uses the 38mm. I ended up with an MSR of 38mm, by specifying for an XR500R. Should be interesting... Thanks!
I understand, OnO. Any of the large chain rollers which has a diameter of 38-42mm should work just as well. Spud
Greetings Sir Spud. I am pleased to report that after a "season" of riding with the front roller, all is well. Little wear is apparent and she still rolls smoothly. MSR replacement designated for the XR500R (my receipt doesn't show the MSR part number )
I have now ridden about 30,000 miles with my 'chain slipper roller.' It continues to function very well, and I haven't had any problems whatsoever. However, I have stopped using my Spud Rollers in the bike's chain guide. I discovered the impact from the drive chain was causing the roller bolts to fracture the plastic chain guide. Therefore, I have removed the Spud Rollers from my chain guide. In fact, I haven't even replaced the chain guide slider. I have left the bottom of the chain guide open. Since I am not taxing the bike's suspension anywhere near its limits, I haven't had any problems result from opening the bottom of the chain guide. Therefore, my experiment with chain rollers is complete. If I ever decide to once again enclose the bottom of the chain guide, I will revert back to the stock, chain guide slider. I have sent a personal message to the forum moderator asking him to close my Spud Roller thread in the Vendor's Forum. I wish to thank everyone who purchased my Spud Rollers, and I wish you all ride nothing but happy trails. Spud
spud, I have looked till my eyes are sore, what size roller to use for the single roller with a 48 tooth rear sprocket? now i am confused, read post 48 and just don't see the reference to no rollers in ther rear slider bracket. was it some where else? post 48 "If you can manufacture any size you want, here are the optimal dimensions. Rear Chain Guide Roller: 24mm X 24mm Front Chain Guide Roller: 30mm X 24mm I am currently using two identical chain rollers, size 24mm X 26mm, in my chain guide. "
