Stromette here in need of support and suggestions since apparently it is not available from Suzuki :shock: :twisted: regarding the cush drive for my 05 DL1k (CA model if it matters). It currently has 30,000mi. At 20k Jim noticed the cush drive had enough excessive play to go warrant ordering a new part given the mileage I accure. We were both surprised w/only 20k there was any indication of replacement. There was no great concern at that point since the excessive freeplay was only slight, the part had been ordered and my travel schedule and maintenance had a specific plan to include the replacement. Jim advised me that when he ordered the part he learned that, oddly enough, there was an updated part # to the original part # which he guessed meant something. We had intended to put in the new cush drive before I left Phoenix for the East Coast but since the part (neither the original # or the upated part #) had arrived it was a mute issue. I wasn't noticing any driveability issues at this point.

After arriving TN and while cleaning the chain I noticed a definite increase in the sprocket carrier free play from the last assessment; so much so that I went w/Stromtrooper SCraig in Nashville to his dealership to order the part so I could put the new cush drive in when I put the new rear tire on this week. I thought I noticed the shifting seemed slightly different. That was a over a week and probably 1000+mi ago.

I've noticed in the last few days that upshifting in all gears, but especially into 1st or 2nd, felt really weird and had a very definite “KER-CLUNK” to it. The feeling is something I can't say I've ever felt before (on any bike) and is hard to describe. Downshifting at higher revs feels kinda strange too...only way I know how to describe it is like there's a kickback, similar to when a chain is way too tight or maybe how a wet clutch feels when it's way overdue for an oil change. (Surely I don't need to remind you at this point I'm mechanically declined). I checked, cleaned and lubed the chain just to be sure but found nothing. I also noticed a difference in the handling of the bike insofar as the rear tire, especially in tight twisties. I believed what I was feeling was due in large part to a significant flat spot as there was a slight wobble feel.

Today when removing my rear tire the rear sprocket literally fell out. I was shocked but also relieved since I was told the part was going to be in by Mon (of this wk) and I was headed to the same dealership anyway to have my tire mounted and could just pick the part up then. I thought smooth sailing (or at least shifting) would once again by mine by sunset today. So, I take my tire in and find out not only had the cush drive not arrived but “We're showing there are none available in the US and Suzuki has no scheduled ETA for the part.” I called Jim, who said no sight of delivery either to his order that was placed over 3wks ago.

I left the dealership kinda stunned actually :shock: , not really believing what I just heard, and so I started thinking.... when does a worn (ok, seriously shot) cush drive become a safety issue?? Is there anything I should be doing different in terms of actually riding (like in terms of shifting, manuevering, etc)? Is my USA Four Corner w/RTJohn in the next 3-5wks in jeopardy? Can I “borrow” a cush drive from another DL1k? Do all DL1k years use the same part/updated part #? Can I find a Strom that is being parted out and do it ASAP while being on the road? Since apparently our country has no rubber dampers for a Strom do any foreign Stromtroopers have access to dealer's w/cush drives that would fit my Strom? Why is getting support re this from Suzuki so freakin' difficult and what's the updated part number all about? No, I'm not in a panic...just yet. I keep thinking “how can this be”... this is EXACTLY what I try to avoid.... see, I don't own bikes that have difficulty w/dealer/parts support. I won't own rare bikes or 1st yr new models of any bike (ahem, like RTJohn's situation last wk w/his new 1200RT) because I put lots of miles on quickly and I don't want to be the one who is the guinea pig for determining what breaks when nor do I want to own a bike that collects dust waiting for parts to arrive. I chose the Strom for it's reliability (which it has been ROCK SOLID :!: ) and for part/dealer support since my travels take me far and wide... (RT would tell you he struggles w/both for his bike).

I put the new rear tire on and rode about 65mi this afternoon. Without the flat spot in the tire the wobble feel in tighter twisties is clearly noticeable to me (though very slight). Maybe it's my imagination but it sure seems more noticeable when going left.

I'm really not sure what to do. :( I have no idea why I'm seemingly the only owner w/this issue and at this juncture it really doesn't matter. I do know that I am a rider, I'm not a mechanic. I know HOW (not necessarily WHY) my bike runs and I am acutely aware of changes (probably has a little something to do w/the 30k miles in less than 29wks on the bike don'tcha think?). I firmly believe this cush drive issue WILL at some point force me to park my Strom, either for safety reasons or out of sheer frustration w/driveability issues. :cry: Where do I turn for support for a part to keep my Strom on the road??

P.S.
Original Suzuki part number: 64651-35F00
UPDATED Suzuki part number: 64651-35F10

This may help it may not but about 30 years ago ( yes that long ago ) I had a Honda SL 125 that we abused heaps. The cuse drive on that wore badly ,so we simple went to a rubber supply store and bought some rubber strip which we cut to lenght to help pack the cush drive . The original ruuber cush drive was worn ( actually not so much worn as it was more compacted ) about 3/8- 1/2 inch by memory . When we re insstalled it worked a really well .You may be able to do the same ,also check in this board about changing the spacers to realign the chain sprockets as per someone else's post on this board.I hpe this simple fix works for you .

Thank you, graham, for your suggestions. I will check into it. Is the realigning you speak of regarding what "master mike" developed?

Stromette there may be multiple things going on here, or you're oversensitive to the bike because you're worried about the cush. Any difference in shifting feel is going to have nothing to do with the cush drive- shifting feel for me has only changed when there's some difference in the oil- it's too old or i just switched to a different type. The only way you're going to feel a bad cush is on/off throttle transition, and that will be complicated by chain tension (make sure it's set right). as far as the wobble goes again the only impact the cush has is with throttle transition, if the back wheel is really wobbling there's something wrong with your axle or bearings, and that is bad. you should be able to tell easily if this is the case though, just put the bike up on the center and try to move the rear wheel laterally. if there's any play then you may have a problem, have a pro look at it. the cush itself isn't such a big deal compared to the above, just avoid abrupt throttle transitions like yanking the front wheel into the air or doing trackdays. :D

YOU SURE ABOUT YOUR STATEMENTS? :wink:

after the way she said that "no true LD rider has stock mirrors"...mebbe its just a way for those stock mirror folks to get back at her. many people make generalizations and proffer them as biblical truth......when they are just blowing smoke up the proverbial rectum of society.

Met and rode w/3 other Stromtroopers today (had a blast) and who all looked at the problem. It is DEFINITELY the cush drive. The 3 of them concluded the freeplay is at least 3/16 of an inch (bike on sidestand). Their comments were "wow", "oh my god," and "something is definitely wrong" when seeing the problem. One of the Stromtroopers had an 05 DL1k just like mine and his freeplay was zilch. Perhaps this is a "see it to believe it" kinda thing, I don't know. I do know there is a problem and it is worsening. Jim called while we were at a gas stop and said that he got confirmation that Suzuki is no longer manufacturing the orginal part number and that the updated part is indeed backordered w/no time frame of availability.

At this juncture I'm interested in replies that support a resolution to the specific identified problem (replacing a shot cush drive) given the circumstances of being on the road and upcoming travels.

unless your crunchy tranny and wobbly back wheel were your imagination, you have bigger problems then the cush drive.

assuming that I'd call a suzuki dealer that knows his a55 from a hole in the ground and find out if the DL has the same back wheel as some other model and use that cush. other than that you're gonna have to rig something up- yank the back wheel and go to a good used bike place with good mechanics that hopefully has a lot of parts laying around and match it up to something close. Your only other option would involve a magic wand.

rxcoop did i miss something?

I rarely respond to postings like this since it is a waste of time. However, if you are going to quote me than it would be prudent to provide my actual quote, which was "I don't know of any LD Strom riders that run stock mirrors." You're interpretation of that statement is just that--your interpretation and not my exact quote like you posted above. If you'd like clarification of what I said then ask me. How your reply offers support for addressing my cush drive issue is beyond me. I'll ask you to keep replies in this thread on topic to the cush drive.

The short version is a 2mm misalignment in the stock setup causes excessive wear on the cush drive and carrier bearing. The higher number of the two part numbers helps with the bearing but was standard starting with the K5. Some people have used sections cut from inner tubes to fill out a sloppy cush drive but the bearing needs to be okay. Master Mike makes a wheel spacer set with a 2mm correction to align the sprocket properly and prevent premature wear of the bearing, sprockets, cush drive and chain. He is based in Switzerland though.

Go out to your bike, and put it on the center stand. Hold the rear wheel solidly and try and turn the sprocket. On the other three bikes there today (two 650's and another 1000) the sprocket did not move at all. Not even a little bit. On hers the sprocket has about 3/16" of fore and aft movement at the chain. I saw it, I felt it. It ain't right. Since the only thing the sprocket hub sits in is the cushion drive sections it has to be either those segments or the sprocket hub itself and the dealer here in Nashville looked at the hub.

I don't think the problem they are reporting is what is going on w/my bike especially since I read no mention of seriously excessive freeplay that progressively worsened. I don't think there is a coincidence either that Suzuki issued an updated replacement and now has zero available stock for what I believe to be the very issue--these rubber damper things. Thankfully, I just talked at length w/oldgoat and we will be meeting next Fri in VT. He and Jim both suggested using bicycle tubing to fabricate something w/the cush drive until a replacement cd can be located so that is the plan at this point.

I will give you a call tonight or tomorrow late morning, greywolf.
