Question about 2006 Suzuki SV 650 S

1 Answer

Front Suspension I just purchased a sv650s. I have read only positive remarks about this bike and plan to own it for some time. My question is this: The only thing that dosen't have a good feel to it is the front suspension. It feels uneasy when I have it leaned into a turn. I received no owners manual with it and while I am waiting for one I would like to know how to adjust the front suspension. All I can guess is that there's not enough/too much preload on the springs. I have never felt this unsure on any other bike I've owned even without the suspension being set up for my weight. Any ideas?

Try this from sv650.org FAQ list great site try it. Quote Here's a piece for your FAQ section. Oh....OK then.... My reworking of the SV continues - just thought I would send the lazy way of changing the fork oil and adding spacers - without removing the forks! Lets face it, removing the front wheel, mudguard, calipers, forks etc is a right pain - there is a better way and it can be done in under 15 minutes! You need a thin bamboo pole about 3 foot long, 2 metres of 10mm flexible pipe, a bent nail, 1 litre of fork oil and a selection of 35mm washers. You are now ready to convert the washed out front suspension without removing the fork legs and it can be done in under 15 minutes! First loosen the fork caps, now jack up the front wheel clear of the ground. Remove the fork caps completely - dont worry about the caps popping upwards with spring tension, there is none! Remove the metal spacer tubes from inside the forks. Attach your bent nail to bamboo stick with tape, grovell inside forks and pull up to remove spacer washer, then grovel again and remove the spring. Remove bent nail, insert bamboo pole into one leg, until it goes to the bottom - careful, the bottom has a recess in, get it right and you will feel the pole go down another six inches. Pull back out and mark oil level on bamboo stick with black marker pen for reference later. Attach pipe to bamboo stick right at the end and again send to inside of forks, down into recess. Suck on pipe and all the oil will magically drain into can. Catch what can! - Whoops sorry you need a can to catch oil in! Process takes about two minutes and does remove all the oil! Drain second leg same. Pour 480ml of 15 sw oil into first leg, insert bamboo stick and careful top up to reference mark made earlier. Follow suit with second leg. (Mr Suzuki was a full 30mm different from one leg to the other in my SV - you now have two perfectly balanced legs - 489 ml is the correct amount per leg) Insert springs, then amount of washers to increase preload that you require - I inserted 15mm each side and it feels not bad. The washers must be 35mm exactly, anymore and they will not fit inside the legs. I managed to find some at 35.5mm and had to grind the .5mm off. Just drop an equal amount in each leg and top off with the original suzuki washer. Insert the spacers and tighten up the fork caps - you will have to push down hard as you tighten as your washers are now doing their job. Lower jack and burn rubber up the street! Some people prefer thicker 20 sw oil, or more spacers, around 19mm not uncommon. With the rear set on number four, the front now feels matched, doesn't flop when braking and has helped no end with the pitching (UK roads). Rates about a seven on the improvement scale. You could do better and fit aftermarket springs but not for the £8 the above cost inc the oil. So there you have it - the laziest way of uprating the SV front yet!

Rear shock air preasure for two people


Hi Don:
You're getting into the logistics of setting up the bike which is very cool.
Since you're planning on carrying a passenger it's a good idea to bump up the pressure so that the ride is comfortableand be bike handling is "tight, but not so tight that the suspension can't travel.
You have several variable to deal with:
- Make and model
- Bike weight
- Weight of you and your typical passenger
- Kind of riding and road conditions you are planning on.

Time for me to get to the point.
What I would do would be to start with just me, with the bike Not running, and on a level surface. I'd straddle it and then drop down onto the seat, seeing how much travel there was. Then I'd get my passenger to get on, and I'd repeat the bounce. If the ride height dropped or the "squish" was too soft, I'd add about 5 PSI and try again.

When the stationary position setup was done, I'd do some short road tests.

The objective is to find the point where the solo ride is still not too harsh, and the doubles is not too soft.

It's summer here on the west coast of Canada and Time to enjoy the ride.
Hope you do too.

Tip

Susspension set up for Motorcross bikes


When I need to set up a motorcross bikes suspension I set all the settings (both rebound & compression) to the middle of the range on both the front suspension & the rear suspension

Now, measure the distance from the inside of the rear mudguard and the top of the rear tyre & note the distance.

Now repeat with the rider seated in position and note the difference,

This value should be 20mm. If not adjust rear spring pre-load to correct.

Now, measure the distance from the inside of the front mudguard and the top of the front tyre & note the distance.

Now repeat with the rider seated in position and note the difference,

This value should be 15mm. If not adjust front spring pre-load to correct.(if adjustable).

This gives you your starting point for the fine tuning with the dampening adjustments to suit the riders preferances.

Just want to raise rear shock


Firstly, the best starting point for a suspension set up is the manufacturers original settings. This allows you to go back to a baseline set up, no matter how much fiddling around you do.

Because everyone is slightly different and of differing weights, then a bike will work best when set up to the individual. The following rough guide for a solo rider has worked on bikes I've owned to give me a good suspension set up for road use.

Initially we'll adjust the preload on the suspension.
The front preload:-
1. Put a cable tie round the front fork stanchion (the shiney bit).
2. Get help from a mate and lift the front of the bike, so there is no weight on the front forks, and slide the cable tie down the fork until it rests on the fork seal. If you've got USD forks, then slide the cable tie upwards to the fork seal.
3. Put the bike back on the ground.
4. Now wearing all your riding gear, get on the bike gently and allow your full weight to settle on the bike in roughly a riding position. Try not to bounce the bike as you do it. You should now be sitting there with your tip toes lightly on the ground stabilising the bike.
5. When everything is stable, get your mate to slide the cable tie till it again touches the fork seal.
6. Carefully get off the bike.
7. The front of the bike needs lifting again until the weight is off the forks. Now measure the distance between the cable tie and the fork seal. Ideally the gap should be in the region of 30 to 40mm. If the gap is too large then increase the preload and repeat steps 2 to 7, if the gap is too small then reduce the preload and repeat steps 2 to 7.

The rear preload:-
1. With the help of that same good mate, you'll owe him a beer after all this lifting, lift the back of the bike so the weight is off the rear suspension.
2. Measure from the centre of the rear axle to a fixed part of the bike above it. Remember this measurement as R1.
3. Put the bike back down.
4. Now wearing all your riding gear, get on the bike and allow your full weight to settle on the bike in roughly a riding position. You should now be sitting there with your tip toes lightly on the ground stabilising the bike.
5. Measure from the centre of the axle to the same point on the bike as before. Remember this measurment as R2.
6. Now the maths. R1 minus R2 should be in the region of 30 to 40mm. If it's greater, then the rear preload needs increasing and repeat steps 4 to 6. If it's less then the rear preload needs reduciing and repeat steps 4 to 6. The R1 figure isn't going to change so there's no need to do 1 and 2 again.

Now we'll go onto the black art of the damping adjustment.
If the bike feels unstable, loose and rather bouncy, then the rebound damping needs increasing. Just try a little at a time until you find the setting best for you. If the bike feels hard and bumpy, then reduce the rebound damping. Again, just adjust a little at a time. Make a note somewhere how much you've adjusted things.
If the bike has a tendency to bottom out under braking, then increase the front compression damping. If it feels too rigid or tends to hop under braking, then reduce the front compression damping. If the back of the bike bottoms out in depressions or feels unstable in fast corners, then increase the rear compression damping. If the back end feels rigid and harsh, then reduce the rear compression damping. Remember to make a note of all the adjustments you've made.

If it all goes wrong, return the bike to standard settings and start again.

hope this helps

I want 2 knw the factory suspension settings for my 06 yamaha yz250


The settings depend on your weight and style of riding (terrain) . Place your settings in the middle , ride , and adjust them from there. Example: If you can adjust the front forks to ten positions (ten clicks) Set both front forks to 5 clicks. Set the rear shock about halfway or on the middle click. Ride the bike carefully over some whoops and jumps and make adjustments by how it rides. The bike will be easier to control when you are close to the right setting for you. My dirt bike rear shock was set to "0" when i got it. Every time I went over a jump the rear shock would try to throw you over the handle bar.

Cutting out at idle


the batery is ok if the engine start avery time. Also the volts are ok.
Have you made any modifications on it? Sport exhaust, sport air filter?
Check also the air filter. Make sure is clean...
Idle speed should be around 1000-1200 rpm. You should have a screw to fix the idle speed. Check it on the carburetors area, or download the manual from internet.

Cheers.

Lower


If it has a mono shock in back there are lowering links you can purchase and install to lower the rear and the front can be lowered by dropping the tubes in the trees or softening up the springs.
I would like to make a suggestion though...
If you lower the bike the suspension will not work as it was designed to.
This is an issue I am trying to overcome with my boy since we have moved to a bigger bike- he can not touch the ground without leaning the bike WAY over. To quote a famous short moto cross racer from the 70's- "they dont pay me to put my feet down". Even I at 6' 2" find it difficult to rest both feet on the ground on some of the newer dirt bikes. But if I do find one that I can rest both feet on the ground comfortably I soon find that I am bottoming out the suspension and riding over the limits of the bike.
This is just my personal opinion... I would rather ride a tall off road bike and have the suspension at hand than ride one thats comfortable at rest and not have that suspension when I need it. Unless you are going to be stopping at a bunch of stop signs then ride it the way it is or get a smaller bike ( maybe a 125).

To me, the best thing about the SG is that it gets you on a Big Twin (vs. a Sportster), and you can modify it any way you want. I bought mine in 2002, and since then I have lowered it, chromed out the engine, chrome handlebar covers, put a mid-glide front end on it, etc. This winter I am putting on new handlbars, I am getting a custom paint job, a new rear end, an all chrome wide-glide front end, and a digital speedo. It has taken me 6 years to finally get it where I want it, but I am glad I'm on a Twin Cam. As far as braking and handling, the SG is really good. Not as good as a sportbike, obviously, but you should find it to be a good ride. I'd recommend test riding one. Many dealers have demo days, pay attention for the next time your local has one, and get out on one, you'll love it.
