    DDD,

    Those button head allens do NOT look like any hardware I've ever seen used on a Honda.

    Maybe the PO installed those after the rivets got sloppy? Just a quess but that hardware says DIY to me.

    Well, between work, work, and building my friends' 77 KZ400, 78 XS750, and 78 XS650, I've been slowly chipping away at my TransAlp mods. Ran errands on her all day today, and have to say she rips!

    Hello AppFan,

    The shock length (& linkages) changed after '88. The difference is about 25 - 30mm from memory. It has been discussed in this thread previously.
    I would suspect you've received the wrong model shock?

    Can the Ohlins supplier advise if there is two types available, and what the difference in eye to eye length is?


    Cheers,

    Dan. :D

    There are many other DIY fixes for the rivets getting loose. The one above shows stainless bolts........would not be my first choice. One is not worried about rust. :lol3:lol3:lol3. Coming loose or not strong enough big concern as we have seen first hand....:eek1:eek1

    Thanks Dan. Ohlins site lists 88-90 and 91-96 on their site with the difference in length being 355 and 378. Do you think the US 1989 would utilize their 91-96?

    Cory and Appfan,

    Sorry fellas but I just can't agree that the shock you both received was the correct one. If I had received it I would have been on the phone with Ohlings right away.

    No doubts that it works and works well but if you dial in the correct rear sag on both shocks you will still end up with significantly reduced rear wheel travel and lower ride height with the Ohlins that you have in your hands.

    The fact that you may not be able to get the correct rear sag with the old standard spring is immaterial here.

    I'm betting that they sent the shock for the later model TAs. For the price of these things you should certainly get the correct one.

    Stainless bolts, like all fasteners have their applications.

    It's important to note that stainless hardware is usually softer than the standard grade stuff that comes on most bikes. Nowhere near grade 8.

    For an application that replaces clutch basket rivets stainless would be the wrong thing to use.

    to start with REAR SHOCKS:

    As many of you know I owned a 1991 Transalp imported bike. I found far more changes to this model vs pre 91 TA's than you will commonly find mentioned on the interent, however the 1991 TA's rear shock was not one of them. I have no recollection of it being any longer nor did it look any different, I cetainly never noticed it. I can't even recall what bike I put it in which means it was undistingishable from any other 89-90 TA rear shock.

    BOLTS: Grade 8 bolts are for the most part overkill in most applications on a motorcycle, the OEM engine mounting bolts are not even grade 8 quality. Having said that I see no harm in using grade 8 for general use if it makes you feel better.

    CLUTCH RIVET alterations: I must have skipped class when they discussed this, why are people changing the clutch rivets to screws, is this a problem?? What am I missing? I would go study a clutch assembly to try and figure it out for myself but I don't get to ask too many questions here.

    Thanks Mark. Not sure why Ohlins lists two different model numbers based on years (88-90 and 91-96) with their 91-96 seeming to be more the same length as the factory one on my 89 but will be finding out.

    The 650 Transalps (2000 and up) used a different rear suspension setup with a shorter shock and different linkage geometry.

    I'm not suggesting that the short shock is for a 1991 model.

    What I AM suggesting is that you don't pay that kind of cash for a great shock and then get one that's 30mm shorter than standard.

    Clutch noise can be the problem, caused by clutch basket connection to primary drive gear being loose. There is cushion system with springs that is damaged. New clutch basket assembly is the fix, if it is not available or some want to save money the rivets are removed and replaced with bolts or bolts are added. Some times the cushion springs are broken causing the noise and or clutch chatter. Then the rivets are removed to service the springs. This was never meant to be repaired in the field. As seen these rivets or bolts are in a high stress location.

    I do not believe this a common problem on TA.

    I just pulled the spring plate from the clutch outer.


    [​IMG]



    I can see that the holes were drilled, chamfered, and helicoiled..

    One can expect that sort of thing from an engine purchased from a cycle salvage.

    Clearly there is story here.

    To Showkeys point it appears that three cushion springs replaced.

    And there were a few times when I really dumped the clutch and it made a squawking sound.

    I have had this bike since 1996 and have been a lot of places on it this way.. It certainly picked the right time to Fail.........

    A new clutch outer with rivets is on the way..........................

    Ray I tripled checked with Ohlins I ordered and revived the correct shock for a
    89-90 TA model HO836

    http://www.ohlins.com/Our-products-new/Motorcycle/Products/Dual-sport/HO-836/


    I measured my bike before and after installation and I did not loose any ground clearance. I'm comfortable with what I ordered and installed. It's what Ohlins makes for our bike and I agree. That dosnt mean one couldn't order a longer version but that's not what I wanted. I wanted stock ride height and that's what I got.

    As Dan said before, really first TA's have lenght different shock.
    I think, those had also bushing instead of bearings in linkages.

    Why can't I figure out the multi quote thing?

    Ladder: I fully agree, if I spent a grand on a rear shock I would need to be 110% satisfied. I just don't see how a shock can be shorter in length and not be giving up something. When a Ohlin is ordered how do they dertermine the "right" rear shock for your particular weight?

    So if I understand what is being reported; even with the shorter Ohlin, if you remove the spring so you can compress the shock and install the shock on the bike you will still have the same wheel travel as with the oem longer short? I am having trouble with the math.

    Showkey, That makes sense, I guess I have never encountered this as a problem, I have never seen broken springs or had a chattering clutch that was not related to warped disc plates or a clutch pressure plate that was all grooved up..

    DDD, great diagnosis and inspection, I like getting to the bottom of things, even if I know it's trashed and can't be fixed.

    RAVELV, That has always been my understanding, 87-88 rear shock linkage is bushings and not needle bearings but I have never heard that 87-88 shocks are shorter than 89-90?

    We installed this rally fairing, made by AfricanQueens based in Germany. The mounting required a bit of improvising, but we got it done. I can deliver some detailed pictures of the mount later if anyone's interested.

    I really do like the idea of getting some KTM forks, everyone I know with a KTM really rates them. However, If I'm going to to the expense of KTM forks I'm going to buy some attached to the rest of a KTM.

    My bike and my usage of it doesn't justify that level of investment in either time or money.

    As a reasonable compromise on money spent and time taken to install I'm going to go for some progressive springs, and some of those Racetech Emulators or Ricor Intimdators. I just need to find a supplier who can ship them to me in Australia.

    I don't own a garage at home, but a friend has gone on holiday for 6 weeks so I have the use of his garage. Its good having a deadline because it means I have no choice but to blitz the repair by devoting all my spare time to it.

    I am also changing the needle rollers in the rear suspension linkages as they have a knock in them. Its going to be a busy few weeks, Fortunately my girlfriend works weekends at the moment so I don't need a weekends pass.

    Ebay just spell corrected my search for "intiminators" to "intimates", I wasn't quite expecting to see lingerie when searching for bike parts but hey, you gotta take it when you can get it....

    What is the fork diameter for a 650 transalp?
