Help me identify this odd aftermarket brake light switch?

I just bought a used 06 400sm with 1700 miles on it.

The original owners spent some money on some weird mods at at least to me.

I noticed that the front brake line has been replaced. It has this goofy billet piece above the bars that is supposed to be for cooling the salesmen said? I just laughed.

I also noticed that the front brake has to be pulled a long way to get the tail light to light up. Seems that on this new line they installed a banjo bolt/ pressure switch. I don't like this at all.

Can anyone explain to me why someone would do this?

Also it has aftermarket chain tensioner blocks. Is this really necessary or just a bling mod?

Also the the rear shock has a white spring on it. Is this aftermarket?

My buddies 07 has a red spring.

Do have pics of this ugly stuff on your bike?

I have a similar switch {I think} on my bike ,works fine maybe the previous owner didn't bleed the system when he changed the switch. Might be an E model master cyl hence no place for a switch but in the line? :thumbsup:

My 06 has a white spring, but pics of the other shit would be nice.

I have had banjo brake switches before and have never had a problem with them. In fact I thought they were more sensitive.

The stock switch is still on the lever assy with the wires pulled off of it and then tied into the wiring for the new switch. The brakes do feel fine but maybe they do need to be bled. All I know is it takes a good bit of brake to get the light to come on. If I just barely tap the rear brake the light comes on instantaneously.

I will get some pics posted up tonight when I get home from work.

Thanks for the responses so far guys.

I lied lol.

I was able to make do with pics I took yesterday.

First two pics are just some general pics of the bike.



Here is a pic of the white spring which I now assume is the stock spring for an o6


Here is a pic of the chain tensioners.


Last but not least is a pic of the front brake M/C

In red is the goofy line cooler thingie.

In yellow is the pressure switch add on.

In blue is the stock switch.


I assume img tags are turned off here and or I need more posts?

Looks stock to me. The "chain tensioner" you mention is a crash bobbin which stops your shock etc getting trasshed when you throw the bike down the road, there should be one on the front wheel. The front brake looks stock and the piece of whatever it is on the brake hose above the dials looks like it is there to stop the brake line "chattering" against the nylar holders on the forks.

Nice looking bike though, have fun.

Actually, looking at the front brake again that does look wierd. Can you take another photo with a closeup of the whole lot, the one you have is a tad pixelated.

I will get some better pics tonight.

I know it has sliders on it or spools as some call them. My question is what is the deal with the aftermarket red anodized blocks on the chain adjuster.

I would say the red adjuster blocks are a bling item. :thumbsup:

The red chain tension blocks are in backwards...the end with the holes should be pointed towards the adjust screw. The purpose of these blocks is that they have more 'meat' on them vs. stock so you don't have to back the screws so far out. Even though you tighten down on the axle nut, there is still force on these screws when you gas it. The theory is that with the screw backed out so far, it could bend. The MX guys have always tried to limit how much those screws stick out of the swingarm for this reason and that's what created the idea of the aftermarket blocks.

They'll work fine as they are, but if you ever take off the wheel, I'd swap them around and readjust the screws.

The longer blocks are nice when you go to a smaller (40, 39 or 38) tooth rear sprocket, as when using the stock chain, the wheel goes back farther with the smaller sprocket. These blocks make it so you don't have to back those adjustment screws so far out.

Thank you MountainDog

I will turn them around soon I am ordering a set of distanzias tonight.

Also on the brake light issue, here is a pic of the add on pressure switch that makes no damn sense and the stock one still on the bike.


well on my gsxr and drz the tail lamp does not come on when using the front brake. rear brake only. and i have not messed with the switch on either bike.

Sounds like you have something broke on both bikes.

I concur, you better get that fixed before someone runs over your ass.

Now that being said

ON my bike this must be a pretty obscure setup since none of you are jumping right out and saying oh yeah that is a such and such kit.

Sounds to me like it is getting removed. :thumbsup:

If anything replace the front brake line. If you want to get rid of the brake sensor deal Ill get it from you. Only reason being i want to run ASV levers on my bike. but ASV doesn't make a lever that will operate the stock front brake light switch.

Well some progress made on the new bike today.

I unhooked the silly pressure switch and hooked the stock wires back to the stock switch. Brake light problem fixed.

The red bling bling blocks are now turned around the right direction and the 3 inches of chain slack adjusted out.

This morning on the way to work the speedo cable fell off. Got that fixed as well.

now all I need is some damn turn signals and more agressive tires and it should be hell on wheels.

Thanks for all the tips so far guys.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks

      I did the fix last night and took some pics and notes to make this easy on people that haven't done it and want more detail. Please chime in if you think I've missed something.
      Required Tools:
      Set of Allen wrenches
      #3 Phillips screwdriver
      small flat head screwdriver
      8 & 10 mm sockets
      13 mm open end wrench (I needed this to remove my skid plate)
      snap ring pliers
      gasket scraper
      compressed air
      Required Parts:
      New clutch cover gasket, Suzuki Part # 11482-29F00
      Tube or can of RTV sealant
      Oil filter and oil (if you plan to change the oil)
      1. Remove your skid plate (if you have one). I have a Tonn's skid plate and it was in the way.
      2. Remove right side radiator cover.
      3. Unbolt the rear brake lever. This will require removing a cotter pin on the backside of the bolt, and then the bolt itself. I was able to swing the lever far enough out of the way without completely removing it from the bike (see pic).

      4. Drain the coolant. This requires removing the radiator cap and the small bolt on the water pump, which has an aluminum washer on it. I rocked the bike from side to side to get most of the coolant out of the bike.
      5. The oil, two options here. You can either drain the oil and remove the oil filter or you can do what I did which is lay the bike on its left side to keep the oil from pouring out of the engine when you remove the clutch cover. I still removed the oil filter so I could clean the clutch cover with brake clean after scraping the old gasket off.
      6. Loosen the hose clamp on the coolant hose that attaches to the top of the water pump and fold the hose out of the way.
      7. Remove the water pump cover and the clutch cover by removing the bolts holding them on. Note that some of the bolts are of different sizes so keep track of which hole you pulled them from. Also, not all of the bolts need be removed, see the pic below.

      8. Remove the old gasket from the clutch cover and/or the engine with your gasket scraper. I then cleaned the clutch cover with brake cleaner as it was fairly oily.
      9. With your snap ring pliers, remove the snap ring from the plastic gear on the clutch cover seen here:

      10. Remove the plastic gear.
      11. Push out the metal pin and remove the washer underneath as seen here:

      12. With a screwdriver or whatever your preferred tool, remove the “E” clip as seen here:

      13. After removing the “E” clip push the water pump shaft out of the clutch cover.
      14. You will now have the part in your hand that needs fixing. Remove the porcelain gasket at the bottom of the shaft by blowing it with compressed air. Don’t not pry it with a screwdriver as it could damage the gasket. Mine was stuck fairly well so I sprayed some WD-40 on first to loosen it up.
      15. If you used WD-40 clean the shaft and gasket with some brake cleaner and then apply the RTV sealant to this area (I reused this pic as its perfect):

      16. Push the gasket back down flush on the shaft wiping away any excess RTV that may flow out.
      17. Reassemble the shaft into the clutch cover in reverse order as listed in steps 9-13.
      18. Place your new clutch cover gasket on the engine and then place the cover back onto the bike.
      19. Put the bolts back into the clutch and water pump cover and tighten equally. I could not find a torque setting for these in the manual so I snugged them evenly.
      20. Put the oil filter or a new one in the bike and put the oil filter cover back on.
      21. Re-attach the brake lever and tighten the bolt to 21 ft lbs. Be sure to install a new cotter pin on the backside of the bolt.
      22. If you drained your oil, refill the crankcase with the proper amount. If you didn’t drain the oil be sure you have enough in the crankcase from oil lost from removing the clutch cover.
      23. Let bike sit for 24 hours to let the RTV set up before adding coolant.
      24. Re-attach the coolant hose to the top of the water pump and tighten the hose clamp.
      25. Fill the radiator with a “Silicate Free” anti-freeze and put the radiator cap back on and tighten the radiator cap screw.
      26. Put the radiator cover and your skid plate back on the bike.
      27. You are done, go ride!
