hyper pro combi kit new rear and front springs

slyxdevil · 07-01-2007, 10:52 AM

at the recomendation of hanksxx i looked into the hyperpro combi kit
bought it 242.00us dollars got it thursday and installed it .. tottally incredible what a differance! feels like a new bike .plus it progressive so even beter for my weight (320), has next to no sag im very happy as bike is a 98 never thought springs were that worn out ,,over the years they wear .,.in my trucks
after keeping for 5 years i always puy new springs, as some bumpy roads would bounce you out of your lane ,and the 2 times i changed springs in 2 differnt trucks it felt brand new again .anyway thats how the bird feels like a brand new bike nice and tight.

in the truck you have big v 8 engine sitting on springs id expect it to wear .never thought bird would suffer suspension issues ..well im sure glade i did it took about 1 hour .going out to rack up some millage ..they give you a 5 mm ride hieght spacer. i already had the 6mm
so didnt install. i think im gonna put it in then ill be at 11mm and see how she handles .the front and reaer springs are longer than stock so it sitting higher
with center stand down both wheels touch ground might have to adjust preload for rear will let you know .. this is a must buy !!

Glad you're happy with the choice Andy. I think it's a good alternative for the larger guys that ride BB's. Did you dump the old fork oil and install the new oil? That helps also.
The Hyperpro instructions tell you to slide the fork legs up to 45 mm above the top tree, from 35mm. DId you do this?
The reason I ask is I'd be careful with raising the rear anymore if you dropped the front. You alter the rake and trail and may induce an unstabile condition. Careful there, big guy...

Let us know what you think after the road test today...Hank

slyxdevil · 07-02-2007, 11:27 AM

so far feels good gonna be running tests all week , changed oil in forks 7.5 weight. didnt do the fork drop must have missed that in directions
so your saying lower forks 10 mm ? will give this a try and let you know
and thanks again for the combi kit info its just what i was looking for and didnt want to spend 1200 on new shock

HANKSXXX · 07-02-2007, 11:47 AM

Andy, my directions say to set the forks at 45 mm above the top tree and that 35 is standard...Take a look at your stuff to verify that.
Glad it's working out so far...Hank

I just got mine today and installed the rear spring...huge difference. Thanks to Hanksxxx for the tips. To Slyxdevil-did you pull the forks completely when you installed the springs? Any info will be appreciated as I am going to do the forks tomorrow.

Here in Holland over 80% of the Blackbird-riders are on Hyperpro now. Evensome using other springs like WP, Ohlins and Wilbers have upgraded to Hyperpro now, and love it.....
The best upgrade to the bike you can do for this little money (in our opinion).

Recently I installed the new 3-D shock of Hyperpro, another great upgrade. My old shock was quite worn after over 60.000 miles on it, and the damping was minimal.....

HANKSXXX · 07-07-2007, 7:56 AM

Can anyone help me with the length of the original front spring spacer?
Thanks... Hank

200 mm's

jjmcjames · 07-07-2007, 11:36 AM

200 mm as of Saturday morning.

HANKSXXX · 07-07-2007, 12:14 PM

Thanks guys....Hank

Just got back from a long, somewhat fast ride after the installation of the Hyper Pro kit. It most assuredly will make your bike handle and ride better. My old fork oil was black so it surely needed replacing. I used the 6mm spacer per Conqsoft for the rear shock that I made instead of the supplied 5mm spacer, and I raised the fork tubes 45mm from the top of the clamp per the directions. My bike now rides much higher-I am 5'9" and cannot put my feet flat on the ground-before it was no problem. Bumps are soaked up much better and it seems to handle much better also, although I am not an agressive rider. All in all 272.00 well spent. Thanks again to Hanksxxx for the tips.

i paid 242$ must be the differance in shipping as i gott it from them in 2 days
anyway hank has recomended that i drop front forks to 45 mm instead of the 39mm the honda manual says they should be at 39mm not 35.3mm that hyper pro says i found my stick that was supposed to be on front page in box ..lol .anyway have not dropped them as of yet as i think it handles sweet as i jacked up preload in rear about 10mm more than where it was stock and that spring is also longer like the front . i love the extra ground clearance
almost feels like a motard..lol best bang for the buck this is something
we should orginize a group buy on !!!!anyway so far im impressed with it and a lil afraid if i start messing with it might get worse instead of better
just want it to be best it can be .so im dropping the forks 10mm and we will see

HANKSXXX · 07-09-2007, 12:50 PM

Andy, please reread my first post...(post #2)

Raise the fork tubes 45mm with a 5 or 6 mm rear spacer..

If you have raised the rear 10 mm already, I'd be careful dropping the front.

jjmcjames · 07-09-2007, 12:52 PM

Me too...the home made 6mm spacer may be too much. Watch the front. Set the front according to the specs and go from there.

slyxdevil · 07-09-2007, 2:16 PM

i set the front at about 2 inches from the top tripple clamp only using the 6mm in rear from jaws funny as i installed that 2 years ago today after droping forks to spec i thightened chain and found play in rear link the pitch fork bolt for rear shock worked it self lose .anyway so now everything is correct 6mm in rear and 2 inches from tree to lock ring 2and 1/16 to bottom of cap going out for test now will post results

slyxdevil · 07-09-2007, 3:24 PM

the verdict is in ..wow it handled and tracked ok before ..but now... yee haa
it drives into the turns way better and so fast it feels real sweet gotta get used to this fast ..so i can go hunt 1 litre bikes...

XXtremist · 07-09-2007, 6:07 PM

Changed my front and rear for Hyperpro progressives. Wow, what a difference! The forks don't bottom out any more, and it's better on rough surfaces. And that's on a two year old bike.

Already had the 6 mm shim on rear, and followed instruction about 45 mm through clamp. The front feels so light now, and turns in beautifully.

The new fork springs were 25 mm longer than OE. Did not want to cut the original spacers, so there is effectively more preload. However, I'm only 150 lbs. So I got some more spacers from breaker's yard, with view to shortening them by 12.5 or 25 mm to soften front a tad. Any advice welcome.

HANKSXXX · 07-09-2007, 6:36 PM

Chris, while, you're at the breakers, try to get a set of fork caps from a Suzuki 1200 Bandit, along with the spring perches. It gives 12-15 mm of adjustment and will make dialing in the springs for your weight much easier..Simple direct replacement after you shorten the spacer....Hank

XXtremist · 07-09-2007, 6:42 PM

Thanks for that tip, Hank, but I've got the extended caps from Jaws for the risers. I assume I would lose the risers with the Bandit caps.

With 45 mm through the clamp, I did note that there is now room for a pair of Jaws' spacers to fit on each fork leg, which would give extra height for the bars.

Chris

slyxdevil · 07-10-2007, 10:48 AM

i almost thought about leaving bars up and leaving space between clip on and tripple clamp ..but ended up sliding them down so they could lock into clamp
guys this is gott to be the best upgrade for the money my bike is 9 years old feels new !!..now were hearing makes a bike 2 years old feel great too.
hank thanks for the help !! just what i needed wasnt looking to spend 1200 on a rear alone just needed stiffer springs .hope to see you thursday night

PJNXX · 07-11-2007, 8:01 PM

I've been following this thread and I would consider doing this suspension upgrade when the time comes. My question is: does the rear spring of the stock shock come off easily? I was under the impression that the rear shock assembly is "fixed". Thanks guys.

jjmcjames · 07-11-2007, 10:28 PM

Mine came off easily. I rented an automotive type coil spring compressor but did not need it. I put my factory shock/spring in a vise and slowly removed the 2 spanner nuts on the top while holding onto the shock body with vise grips-took a little bit but not a big deal. It is somewhat irritating to remove the entire assembly-the nut that held the top of the factory shock in place was rounded off so I ended up removing the battery tray to get full access. The new spring will only go on one way-upside down from what you think, at least mine did. It fits over a plastic sleeve and a steel collar that forms the bottom base of the shock. Go ahead and do it and be sure to install the 5mm spacer on the top, or make one per Conqsoft. The kit comes with a 5mm spacer but I used a home made 6mm spacer. Get the front fork springs also-my bike is a '98. My fork oil was black and the ride difference will be noticeable to say the least.

slyxdevil · 07-12-2007, 10:46 AM

mine came off like butter ,but it in vise as per directions and off it came cleaned it up put new spring on shock put back in bike whle job is about 2 hours maybe 2and a half depending on how crazy u get

turbo50jeff · 07-13-2007, 10:51 AM

Don't like the hyperpros. Initially I did, but now I've changed my mind. The front I also put in 5 weight oil and it's better on small stutter bumps, but on square edged bumps it's still harsh. And now leaned over the front doesn't have enough rebound damping which causes the line I choose to change. I just bought a 2007 cbr600rr to go carve corners with. MUCH better! I don't want to spend $2000 plus dollars on my BB's suspension to fix something that should be correct from the factory.

slyxdevil · 07-13-2007, 1:53 PM

hell you should have bought the 1000rr its what an inch bigger frame wise and tons more power

Banshee · 07-14-2007, 8:23 PM

I found that the harshness from those bumps was fixed on my '98 by having Gold Valves installed in the forks & shock. The oil pathways in the valve bodies are much larger in the Racetech items than in the Honda ones. The rear valve in particular, the Gold valve there had oil holes about 6 times the size of the Honda valve. Nett result, the diaphrams do all the work of controlling the flow, instead of the oil holes and a MUCH smoother response to sharp bumps.
