Title: DR650 - rear shock or say goodbye ??
Post by: andy230 on May 10, 2010, 09:03:48 PM
 :'(

Oh woe is me!  My brethren, advise me in my hour of need!

Recently on the DR: fork seals, brake pads, rear wheel bearings, chain and sprockets, re-pack the can, clean, polish and generally make acceptable, and slightly more legal.

I was a little irked to see the forks leaking on Friday, but resigned to getting them off and giving them to "the shop".

Imagine however, my dismay when I saw this morning that the rear shock was also leaking.  Ah fuck!  >:(  However, there was still damping this morning.

Not so on return this evening!  Like a bloody trampoline!!

So, what to do?

A hagon shock is 300 quid.  So thats clearly not going to happen, given recent outlay. 

Is a monoshock rebuildable??  Ebay trader reckons a hundred quid, plus carriage.  Resonable?  Boyd, didn't we get the racer shock rebuilt?  How much was that?

A rough 2nd hand one is 50 quid plus carriage, but that seems like a bit of a waste of cash for someone else old rubbish.

Alternatively, I could punt the whole shebang, and waste the cash I've just paid out.

I'd get a couple of hundred for it.  Or spend another couple of hundred to keep it.

I hate throwing stuff away, but its getting a wee bit too dear!!!

any advice appreciated

Bad luck matey :'( Think you've got to take a position on the bikes value to you. If all else is good, she's running sweet and you plan on putting miles on her, then £300 over a year ain't that bad.

If it's used once in a blue moon, all else looks dodgey and sounding rough, then cut your losses.

Might want to look on ebay for another one and put the two together to build 1 good bike.

If it was me i'd invest some time into seeing if it can be re-built or try the scrappy's. I've had a few bits from scrappy's and I've never been supplied with rubbish.

Hope my perfect example of fence sitting helped ;D

Hi andy,

Been in the same situation myself, I chose to buy the Hagon unit as I understand the original can not be rebuilt, Hagon were really helpful and built a unit to suit what I do with the bike and my weight (ok cue in 002 and Rod G). I have not had to adjust the unit now in 4 years and it proved to be the last big thing I needed to get the bike sorted out. If you intend to keep the bike and use it then go ahead, get it done, if you are selling it in 3 weeks time leave it to the next owner.

Firstly I'll echo what the others have said with regards to replacing it. I've a Hagon item in my DR600 and it's ok. Another option could be Nitron, they built a shock for my Tenere, and very nice it is too. Failing that, and without wishing to seem like too much of a vulture, I'd be interested in the bike if you decided to move it on, I'm after a DR to convert for Flat track racing next year.

Hmmmmm

thanks guys.  Devil you know I suppose....

I have a few irons in the fire, but 300 quid is a fair whack for a bike I only use for work (tho admittedly, it always starts, and usually stops after a fashion, doesn't get knicked even if I leave the keys in it, and can lie out in the rain, plastic guards are good for spills, tank is steel but nice, it has a big top box, good tyres,....)

Hmmmm :-\  Looks like I'm keeping it.  And having to find 300 squid    :'(

Tho I have always quite fancied an enfield....  Anyone got/ know of a 350 reasonably cheap??  Possibly consider a 500, but I will only really use it to get into central london for work....

I think I am too tight!  Just had a look, and even enfields are not that cheep!

Hello mate,

Well, you'd be very welcome to 1st refusal if I get shot of it.  However:

There is a crack on the lower frame tube, next to the tack where I welded over the last crack   :D  so maybe not the best basis for a racer!  I always paint over it just before MOT   :o   but argue with him that the engine holds the frame together anyway....!  And it always passes!

the engine is a noisy old bastard, tho admittedly it has never gotten any worse in the 16,000 miles I've hammered it (always regular oil changes mind).  But I dont think it would last a season at full bore without a rebuild.

Plenty of good bits on it tho.  No lecky start (good for racing I s'pose?)

Will let you know what I end up doing...

(got anything you want rid of?!)

Cheers for the first refusal offer. As for the welding and rebuild, that's no problem at all.
Got a GPZ500 to potentially move on, but it needs some TLC. Oh and a Jawa/MZ beast.
Anyway, bear me in mind.

I have had a supposedly unrebuildable rear Showa shock rebuilt by Revs Racing in Halesowen a couple of years ago.I think it cost about £100.Might be worth giving them a shout.

Thanks Dave,  most guys are coming in around that mark.  Can't really complain that the cost is not reasonable, its skilled labour, and specialist parts...

1974 Jawa frame, MZ250 engine, YPVS pipe, Dunstall bodykit, Suzuki GSX250 forks and wheels, BMW R90 bikini fairing. It's, erm, interesting. I have plans to strip it back and do something a little fresh with it. We shall see.

I understand the original can not be rebuilt

Andy,
I just checked up on this, I actually bought the unit from Hagon 9 years ago and it cost £180, I am still using it unadjusted. It is highly likely that the rebuild situation has changed in this time so I should have said "at that time I understood that the original could not be rebuilt", but as the bike only retired from regular daily use some 3 years ago and became a winter bike I think it's not bad value for money. Sorry about the duff info.

John

Hmmmm!!  Maybe I like (even if it is a stroker....)

Any pics?

Is the frame definately built in 74??  ie. not, maybe, 1973, if you see where I'm going with this no-tax-to-the-tories type idea??    ;D

This is the only picture I have of it, and I'm afraid it is very much a 1974 bike.

Thanks for the piccy!  Looks interesting!

But I think its going to be cheapest and easiest to just get a new shock.

Will check if the OEM is rebuildable once its off.

thanks for info & chat, gents

No worries, could you do me a favour though? If your 650 has the rear disc, could you measure the diameter and length of the lever pivot for me please? Or even a picture of how the lever locates on the frame would be appreciated. Cheers

diameter and length of the lever pivot for me please?

Hi mate, Pedal to pivot is 20cm (approx, by steel rule!).  Pivot to m/cyl clevis (towards the rear wheel) is about 5cm.

Or even a picture of how the lever locates on the frame would be appreciated.

The pivot goes thru the frame, secured with a big washer and split pin on the inside.  Crude but effective! 

Cheers, andy
