Commonly asked questions:

Q: When do I need fuel management?
When you change both your pipe, and intake. This includes "Ducks Mod", and modifying the stock exhaust, in any way. Some report that the bike runs better with fuel management, even when completely stock, but you need it when you modify both intakes (not including just K&N filters), and exhaust. You can safely run your bike without fuel management, if you only change one, or the other.

Q: What is the best fuel management?
There are several choices for fuel management. The correct answer is which ever one suits you the best.
1. Cobra fi2000r, is great for self tuning, and is very economical. It can add fuel, but cannot remove fuel. Alot of people have great success with this unit.
2. Cobra power Pro is a new auto tuner, has been out for 6 months but has great reviews so far.
3. Power Commander III USB, is best when used for a bike that you want to have DYNO tuned, and pull every bit of horse power out of the bike. If you were to change intakes, or exhaust, it is recommended to have bike re-tuned. There are generic tunes for several set ups, but for optimal performance, a dyno tune is required.
4. Power Commander V w/auto tune, and B&B auto-tuner. These units introduce a oxygen sensor to the exhaust. This requires holes drilled into exhaust, and a "bung" being welded onto pipe. These units are a bit more expensive, but continuously tune your bike while you ride it. So as the conditions change, so does your air fuel mixture.
5. There are others out there as well, but these seem to be the most popular.

Q: Does a 280mm tire, fit on a stock rim?
The largest tire that can be SAFELY mounted on a stock rim is a 260mm, a Dunlop 250mm, or other 260 or smaller.
See Running a 280mm Tire on the Stock Rim.

Q: Where can I get a clear tail light?
Many people on here have purchased Clear Alternative lights. A lot of problems plagued these lights, and most were returned to the manufacture. Some members have gotten their new generation lights, and have written good reviews on them.
If you are looking for just a clear lens tail light to mimic the "LE" tail light, you can change the lens to clear. The leds under your stock light are red. There is a how-to on here. http://www.m109riders.com/forums/sho...red+tail+light.

Q: My "FI" light is on, what do I do?
Get a code by following this procedure. All the codes, and what they mean are also posted on this thread. How To: Suzuki Fi code check with the Suzuki "special tool"

Q: How do I disable an "FI" light, caused from my SET?
For 2008 and earlier models, follow these instructions: M109r F1. Later models will need an ECU flash or a set valve eliminator.

Q: How do I change, and check my oil?
Please watch this video. It is very helpful, and will explain the 15-3 method of checking your oil level.
http://www.m109riders.com/forums/sho...ter+oil+change See also: Oil Level Check Procedure

Q: Why do I have oil coming out of my LEFT airbox?
The most common reason for this is, overfilling the oil. Some bikes, even when new, or if dealer changes oil, have this issue. Simply drain some oil, and refer to the 15-3 method of checking oil. If the problem does not fix itself, then you can make a "Oil catch can". Installing an Oil Catch Can

Q: How do I remove the body panels on my bike?
A: How to Remove M109R Panels

1- remove 2 push clips on inner side -- push center tab in and pull clips out.
2- remove 2- 4mm Allen bolts on each side of nacelle and pull the unit apart.
3- pull the bulb wire off and remove the headlight unit.
4- remove the screws from inner side of nacelle the break apart the 2 pieces and remove the headlight itself.

SIDE COVERS on each side of the seat must be removed next ! due to the hidden bolt for the rear fender.

Q: What's a "De-beaver", and how do I do it?
De-Beaver means to remove the big plastic piece that looks like beaver tooth, that holds your license plate. To remove it, look here:

Q: How do I "De-Badge" my bike?
First, let the bike sit in the sun for a while. I used fishing line, and put it between the tank, and the badge. I moved it back and forth like a sawing motion, until I reached the end. Then I used a little WD-40, and/or Goo-Gone, and a CLEAN RAG, to remove excess double sided tape left behind. The rest of the stickers come off fairly easily, after letting it sit in the sun. If it is cold outside, and no sunlight is available, I recommend using a hair dryer to heat the areas up a little.

Q: Where can I buy stuff for my 9, and what is available?
Here is a link to get the most "Bang for Your Buck".

Q: I saw some guy who had a design on his covers. How did he do that?
It is called a "Ducks mod". It is available here:
He is a member here, and his screen name is "Ducks517".

Q: How do I fix the "clunk" when I shift into second ear?
1st, THIS IS NORMAL! So is the vibration you get around 3500 rpm.
There are a few things you can do. Try "shifting like you mean it". Don't try to ease it into 2nd. Shift it with meaning!
A user developed option is shown in this thread: http://www.m109riders.com/forums/sho...2nd+gear+clunk
The aforementioned option emulates the shift star kit, available from Meancycles.

Q: How do I post big pictures, on a thread?
A: When you are typing a reply, you will need the internet address for a pic to make larger.

To get this from a pic on a website:
Right click on the pic, scroll down to properties. A box will pop up. In the middle of the box, you will have something called "address (url)" with a "www....." following it. Highlight this address, right click, select copy.

To get this from an online album ( such as m109riders album):
Click "User CP" from the menu up top
Select "Picture and albums" from the menu on the left
Click on one of your albums or make one
Click on a pic in your album or upload one
When looking at the pic, below the pic is the "www" address, highlight and copy this address.

Now go to your post.....
With the cursor blinking in the box, click on the yellow box with the mountain in the box. (its in between the globe and the quotation box) A little box will pop up. Delete the "http" that automatically pops up in the text box, now paste your image address in that box and hit ok. Your image should pop up.

Another way you can post an image from an online album
Go to your picture you want to post.
Below the pic is the "www" address and an "IMG" a.ddress.
If you copy the "IMG" address, you can paste this straight in the thread you are typing.

Q: How do I install lowering bones, to drop the ride hieght of my bike?

Q: What is a TRE, JSD-3M, or GI-Pro?
A: All 3 of these are essentially the same. TRE stands for Timing Retard Eliminator. These are plug and play items, and are very easy to install. These will make the throttle response less choppy, and will move the rev limiter in 5th gear from 6500 rpm, to 7400 rpm. The GI-Pro is the only TRE with a gear indicator, that can be mounted on your bike, to show you what gear you are in. These devices trick the bike into thinking it is in 4th gear, while you are in 1st,2nd,and 3rd, thus eliminating the timing normally retarded in these gears. You can also make you own.

Q: My bike is acting like it's not getting fuel. (AKA "limp mode")
A: *ATTENTION*Anyone having this problem, CHECK YOUR CABLES FOR YOUR S.E.T. VALVE!! It has been brought to my attention, that this may be the cause for your issues. If you are running a stock exhaust, make sure the cables are the same tension. You can adjust these on both sides of the cables. If you do not have stock exhaust, pull your SET wire from the ECU.

I believe this issue is the SET is out of adjustment, and/or the SET cam is bad. If either of these things happen, it will put you into limp mode (according to the manual, you may or may not get a FI light!). SO, if you are in limp mode, you will know because when you shut bike off and back on, and it runs fine, but then does it again shortly afterward. Limp mode is designed to put the bike in a "safe zone" so no further damage can be done. I truly believe this will fix your problem.

Once you have checked these... Put your "special tool" back into the connector, then with the cut off switch turned "ON", TURN THE KEY ON AND OFF 3 TIMES. THIS WILL CLEAR THE CODES FROM THE ECM! Problem solved!

Thank you to Matt, and Tony for you help with this!!!
Thank you Dan and Tiny for being the guinea pig's!

Q: How do fix the clutch sleeve hub nut?
A: Loose clutch nut repair by Listan1

Q: Will rain effect my after market intakes, or Ducks mod?
A: NO!!! Take a shop vac hose, stick it out the window one day when it is raining. The amount of water you will suck up will be very minimal, if any, and that has way more suction than these intakes. Look here if you need more peace of mind than just my word:
cant freaking decide (intakes)

Q: When running a rear tire on the front of my bike (160/60/R18 etc.), do I have to run the tire in reverse?
A: Yes! The tire should be mounted in reverse! (directional arrow, tracking the OPPOSITE way) This quote is right off the Metzler web-site:
Rear tires can be mounted at front wheels?
When producing tires, the top cap is heated with an angle bump on the carcass. To prevent the detachment of the assembled edges the tire has to be mounted (concerning the main stress: acceleration force at the rear wheel or wheel brake force at the front) corresponding to the respective declaration.
Therefore the declaration of the driving direction at the tires sidewall is a very important safety regard and has to be noticed absolute. It is not allowed to mount front tires at rear wheels.
In case you intend to mount a rear tire on a front wheel it has to be assembled contrary to the driving direction declaration (direction of the arrow at the tires sidewall). Please observe the standards in your country. In any doubts we kindly ask you to consult your dealer.
