restore old shocks or toss out??
« on: January 11, 2012, 11:54:30 AM »
I was planning on buying new shocks off the bat but I've been hearing a lot about restoring bikes to original state.  My shocks are pretty grungy and rusty. I think with some serious elbow grease and time I can make them new again. My question is is it worth it? Are the shocks junk? Should I just buy a new pair for 100$ and say f it??

I recently put a post up about shock recommendations, from what I gathered from that thread and some searches, if you aren't willing to spend more than 200 it's not worth buying replacements. I've seen some Koni/Ikon 7610 pretty much look like factory and from what I read much better shocks than stock and rebuildable...which is big in my books since I never plan on getting rid of my K1.

<edit>
oh and if you want to keep stock, old new stock of OEM shocks are steep, think over 300 for a pair from what I've seen on fleabay...

+1 you will not get any thing until you get to $200 or $300 and up. Look at progressive 12 series if on a budget. With heavy chrome springs maybe $200-$250 but that was a couple of years ago. I will try to find you a link

Shop around You will find a better price than this. But I would say this is the starting point and you can go to a Grand quick. It is how they feel not look. But I'm not a knee dragger ;) They cost too much. The knees that is .Twenty to thirty grand each :o I know I bought two. ;)

On the Honda Twins site I saw someone drill a hole in the bottom of the shock...dump all the old oil out...tap the hole, add new oil and away they went. Said they got pretty good results as long as the originals were not leaking to begin with...

I rehabbed my shocks on my 360 with directions from the twins forum. I brass brushed the rust off the springs but that is creeping back. The shocks themselves have held up well and the ride is a lot better than before.
I would do this again in a heartbeat!
Here's a link to the twins post.

the other night i disassembled my shocks to check damping and remove the shrouds.  to do this i compressed the springs a bit, took off the split collars, and removed the upper cap and spring.  damping was fine, so i cleaned/polished/steel-wool'd everything (even inside the spring) and reassembled.  they look great, but are sprung a little stiff for this lghtweight.

don't need no spring compressor or vice.   8)   

i just compressed the springs by hand (rubber gloves helped) and popped the collar half out with a screwdriver held by my teeth.  with one collar out i could lever the spring down a bit and remove the other collar.  boink!  all apart.  no need to replace the seal or fluid, damping was nice.

What about these less than $100 dollar shocks on
Ebay.  http://www.ebay.co/itm/170655373075?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

I don't see how original shock with not oil can be as good as new shocks with oil even if they are of a lower quality.  What do you guys think on this one.  Anyone want to weigh in?

there was a thread somewhere around here about those shocks, the consensus was that they are not worth the time or the effort to get them to fit right. Kind of like buying a $500 turbo kit for your 4 banger off ebay.

however, I would like some info on these, as they are in the sub $100 range:

and yes, we've all heard "you get what you pay for", i'm not looking for that, i want to know if someone's used these and how they like them, or if they are junk (if found to be after they were used)

Well I just got down to grabbing these shocks...how in the world do I bust these apart by hand???????????? These are like tanks. Any helpful info would b great! Do I twist them to the left and push or do I need to call a special opps field and have them throw a hand in while I try and execute this project.??

I have a set of those and will not use them on the bike, they are cheap crap and don't work very well, the bottom section is not very strong at all. There was a guy that had a blog and he spent considerable time rebuilding them to work, including replacing the lower part with a stainless steel clevis. He also changed out the seals and the oil and they then worked reasonably, he went on to say that they weren't worth the trouble.

Bone saw, sorry dude but when it comes to suspension "you get what you pay for" is correct, I find it interesting that a shock that works on a 250 {in the link}  can also work on a 750 or GL 1000, thats just wrong, the weight differences alone should tell you that. It all boils down to what you ride like, if you ride hard and like twisties {and value your life} buy something like the Ikon {Koni} 7610 type shocks, they aren't that expensive and are fully rebuildable and parts are readily available, if you ride just to commute and don't really push your bike, look at progressives or something similar, they will work as a shock and are cheap, they are not what you would call a performance shock like the Ikon {Koni's}.  Also remember that good swimg arm bushes and a clean serviced set of front forks and good steering head bearings will go a long way to helping your bike handle well..... ;)

if they are not leaking I usually use them because as said there are a lot of junk ones out there and good ones are exspensive

First: The actual body doesn't come apart. With my factory shocks, I powder-coated the spring and all the retainers semigloss black. The body I left alone (chrome) and because they weren't leaking and still had good resistance, I'm depending on them to work well. It all depends on what you're looking for. I have come to the conclusion that I am going for a look. I'm not winning any races, nor am i really going to drag a knee (I have a more modern bike for that).

You don't, you need tools to take the stockers apart and they were never designed for rebuilding anyway.

The stock shocks on these bikes were mediocre Showa's that were not meant to be rebuilt so the bike could hit a certain price point.
Honda probably assumed most people keeping the bike for any amount of time would upgrade the shocks after a year or two which is when most of them turned into pogo stick pumpkins.

no idea what bike you have.  to take shocks apart on a K6 read my previous post.  up about 10 or so.  compress the spring by pushing straight down, then pick out the half-collars.  disass, clean, and reassemble.  easy.

Taking the springs off the shock/spring assembly is not the same as restoring the shock's damping action.

With the spring off, you can check for damping action, which is the resistance the extension rod presents from moving within the shock body.  This action is what keeps the bike and wheel from bouncing, and allowing the tires prolonged non-contact with uneven roadways. (Quite important while leaned over in a turn.)

The springs carry the weight, and are selected to provide both motorcycle ride height and position shock piston in the shock body for even travel distances, and allow it to respond to both compression and extension without reaching the limit of travel too frequently (bottoming out/topping out).

You can ride a bike without any shock action (and many do).  But, with such a bike, it is best to encounter washboard roads while the bike is straight up, rather than leaned over, as the tire will be in the air most of the time, depending on speed factors.

I've never gotten around to dissecting a stock shock.  They often fail (lose damping action) well before there is visual fluid loss.  And, there is no easy way to rebuild the stock shock types.  I'm not sure where you would find the internal piston seals.
I've got some that look brand new on the outside, but the extension rod moves without resistance almost 2 inches, and not too smoothly, at that.

My distant recollection of the stock shocks is that everyone used to bin them even before they started leaking, as the performance improvements from fitting aftermarket ones were so great.

Just order a set of Hagons, once you ride it with them fitted you'll be really glad you did.

tt, go up 12 and 14 posts from here.  i checked the damping, it was fine.  hard to pull out, harder to push in, smooth/consistant action and no leaks.  exterior chrome, including rod, is excellant.  stuck 'em back in.  saving some dosh for a new o-ring chain.     

am finding some nice surprises on this refresh project.  i think the shocks have been replaced with oem recently, and also found very nice rockers (little wear) and camshaft (no wear).  cases have been replaced (no engine serial numbers) also.

guees it all depends on your riding style..if you are going to be going to be just putting around town. go with the progresive 12 series as i did. they have served me well. if you are going to be riding canyons and lots of twisties go with a bit more shock.  but as has been stated suspension also includes the front forks. find a weight of oil in them that suits your riding style.
