HyperPro shock install

afterburn · Apr 3, 2006

Last weekend I had a happy day installing the superduper got-to-have farkle: a new shock. I went with the HyperPro Type41 fully adjustable shock. No hydraulic preload adjuster, as I only ride solo. Originally, I wanted a Technoflex shock but after almost 2 months of waiting, calling, ******** and excuses I told them to stuff it and bought a set of HyperPro springs and shock. Should have done so in the first place, as I had them on my VFR and loved it, but hey, call it a brain fart.

Anyway, I made some pics during installation to show off and maybe help someone.

So here goes...

I started on the rear, as that seemed as it would take the most time. First thing to do was to remove the preload adjuster of the original shock. Do not attempt to remove the metal plate between the side of the subframe. It also holds the ABS thingie and not just the preload adjuster.

The preload adjuster is tied down with 3 bolts. The picture shows 2 of them. Just unscrew and let it sit while we move on.

Next was loosing up everything as we get ready to remove the old shock.

Here you see the 2 of the 3 bolts that need to be undone to remove the shock. You need to undo the bolt through the bottom of the shock, and the one of the rear dogbones. The 3rd bolt is the top shock bolt.

Once you remove these 3 bolts, the shock just drops out from the bottom...

And you end up with this.

Make sure you have some grease:

Cause I don't think Yamaha has any. This is the bolt that holds the rear dogbones. You think it was a little dry, maybe?

Installation of the new shock is basically the reverse of removal.

Old and new together.

However, when you have a shock with remote reservoir, feed that through the whole of the shock first and guide it to the brake pedal where it can sit out of the way untill you tie it down.

Shock is mounted.

The shock comes with a nice alu clamp to hold the remote reservoir in the empty space between the brake pedal and engine. Nicely out of the way, and well reachable for when you want to adjust something.

In all, this job took about 2 hours to complete.

After the shock, it was time to move to the front. I should have done a rebuild of the internals while I had the forks out, but I didn't have all the parts and I want to ride. So fork rebuild has been shifted till next winter, when I will install new bearings and seals, clean the forks out and check all there is to check.

Looks quite sad with just half a front end.

Front spring waiting to be installed.

My dad emptying one of the forks and getting ready to put in fresh oil and new springs.

Almost ready to go back in. All that remains is to adjust all settings to the HyperPro recommended settings to use as a baseline.

And of course the commercial to let everyone know this bike just got $1000 more expensive.

On a sidenote: HyperPro delivers and recommends SAE20W oil for the forks. Having experience with them, this is hard. I went with SAE15W, which is thicker than most here use, but I find this to be an excellent balance between the front and rear. The standard settings were also very close to optimal. After testriding, I only dialed in ½ring of preload, and added 1 click of rebound and 1 click of compression on the front. On the rear, I added ½turn preload on the adjuster ring, and added 1 click of rebound, -1 click of highspeed compression and +1 click of lowspeed compression damping.

The final result is a bike that truly is a Supersport Touring bike as Yamaha calls it. No more wobbles, no more understeer at high speed turns. Just hauling ass as on rails, sucking up all the bumps like they don't excist. Now this FJR really rocks.

That's a disturbingly clean and organized work shop <_<

Nice write up!

Well, when you do semi-professional work in there, your customers don't want to leave their bike in a shop that looks like a bom exploded in there.

But besides that, my dad and me like to work a little organized.

That new shock is purty. Thanks for the writeup.

But did you get it done in 45 minutes? That seems to be a priority here. Suspension install races are just around the corner.

afterburn · Apr 4, 2006

Nope, I don't do races when it comes to maintenance to my bike.

I rather do things right instead of fast.

Shock install took about 2 hours including a coffee break and spring installation took also about 2 hours including another coffee break. So approximately 4 hours between starting and ready to ride again.

I swop between solo and two up pulling a trailer loaded with camping gear .

1. Do you foresee any problems fitting one that has the remote hydraulic preload?

2. If I went without the remote preload, how easy is it to add extra turns on the preload ring?

Thanks for the good write up.

1) I don't see any problems there. It does prolly add something like $200 to the price of a part that isn't cheap to begin with.

2) The adjuster ring is easy to reach. All it takes is to sit on your knees and stick the C-spanner in and turn. Not something you'd want to do every 5 minutes, but not complicated or time consuming either. That said, the HyperPro progressively wound springs need less adjusting to load than a regular linear spring. Of course within limits, but whereas a regular linear spring is very sensative to load and preload, these springs are not and forgetting to adjust will not immediately result in a wallowing and ill-handling bike. Again, within limits. It's not a miracle set up once do all.

Thanks, glad you liked it.

Thanks for this writeup. You inspired me to order the same today. I'll post piccies when I get mine and see if the install goes as well in a poor man's shop.
