What's the story on those bags?
a similar excellent quality one piece stand with similar L pads can be had at Harbor Freight for about $36. I use one on my Zephyr 550 and with the same setting is right for my KLX650. Low buck quality, sometimes a rarity at HF, but in this case it is there.
That's pretty unlikely, as there are typically two layers to the diaphragm in a vacuum operated petcock, with the outer edges sandwiched between a spacer. The spacer typically has a drain hole in it, so that if the layer nearest the fuel gets a hole in it, the fuel will exit there. If the layer nearest the intake port gets a hole in it, there will be a vacuum leak, which will cause the engine to either idle high or die (depending on engine temp and the severity of the leak) until the engine dies from fuel starvation as the bowl empties (if the leak in this layer of the diaphragm is severe enough, the petcock will close/not open). The only way for fuel to fill the engine from a diaphragm failure is if both layers fail simultaneously and the drain hole in the spacer is plugged, or if both layers fail simultaneously and so spectacularly that the volume of fuel that leaks past the diaphragms is far greater than can exit the drain hole.
Good explanation Derek but I did have the note that it was "rare".
My ACT gear set arrived last week. Good service from the company.
After the Christmas break th egears are going in, so then I will comment about how it goes.
I am using 15/44 sprockets with the standard transmission 5th is about where I want it for my riding but 1st is too high for tight stuff. Dirk from ACT suggested I try 14/47 with the new gears, so I will try that and see how it feels, but I will try 14/44 first because I hate changing sprockets!
Had the vacuum diaphragm go bad in my DRZ and fill the engine with fuel. It is only a single diaphragm and any leakage goes directly into the intake manifold through the vacuum port downstream of the carb. Gravity will take it straight into the cylinder.
Hello guys. I just pulled trigger on a new 2012. Pick it up on Monday.
It's my first bike ever
Congrats! I picked my 12 up a few weeks ago...my 2nd DRZ400..should never had sold the first one!
Ya im a little tipsy.
Yes this... And it is not so rare once the bike gets old with ethanol fuel. We also had this happen in an old Suzuki Bandit which belonged to a friend with the same system.Manual petcock is the only really safe system IMO.Basically that big gas tank tries to unload its fuel to the lowest point it can....your crankcase and garage floor:eek1.
I am looking for a list of tools for DRZ400s 05. Any info or links? Thanks in advance to my friends DRZiers!
8, 10, 12 and 14mm sockets and whrenches, pliers, allen wrenches,(thandle, you only need a couple) adjustable wrench. A 24mm iirc socket for the cs nut.
If you want to completly tear apart the bike, youll only need a couple of more sockets, one for the swing arm nut, a breaker bar, a torque wrench, thats about it.
I typically use only 1 or 2 different sockets (10 and 12mm, a 14 for the oils drain bolt, a 8mm here and there. And one size allen wrenc ( i dont recall the size) anything else i use for one specific bolt, so i sually have to fish around the bottom of the tool box for the big socket or the allen wrench.
If you do your own tire changes, get 2 long tire spoons.
12,14 mm wrench
8,10,12, 14 mm sockets
Sm. Flat and phillipsmscrew driver (which you dont need if you swap out the 2-3 phillips screws, only used for the clamps
Metal putty, some zip ties, some electrical tape an extra fuse, two tire irons, a length of chain and a chain breaker
Spare master link clips, needle nose pliers.
Adjustable wrench (sm make sure it goes to 24mm, this is for the front and rear wheel bolts)
Youl pretty much use the same 2-3 sockets over and over, so buy a good drive, a good 8,10,12 and 14mm socket. Everything else will be used ocassionally.
Im sure theres 1 or 2 things i missed, but theyre specialty items, used once in a blue moon.
I've never seen a single layer petcock diaphragm. Have a look at http://www.thumpertalk.com/topic/922529-drz400-petcock-diaphragm/#entry9626847. Are you sure the diaphragm's plunger o-ring or the multi-hole rubber selector gasket did not go bad in combination with a leaky float valve?
It was not the diaphragm that was at fault.
Finally got a chance to take my new to me DRZ out on some single track today...
This was a replacement for my KLX250S....and an addition to the stable of a KLR and KTM Adventure...and it fits in nicely
Trails were slick as snot with a bit of rain, mud and plenty of leaves....with the exception of needing some new tires..the bike is perfect for my riding.
Paul....just had to post you a couple pictures of the current state of the nice clean bike you handed off to me last weekend.
Looks like the weather held for you dave! That's great news, glad the bikes stretching its legs too! From the pictures I would say you had a good time!
oh yeah.... going back on Wednesday for some more...new tire is due in Tuesday
Did you get the KLX back together yet?
Ok so who can tell me about suspension upgrades
The DRZ can be set up to cope with anything... It's not just about springs though, shims and oil have a lot to do with the way a bike behaves. Find someone that knows what they're doing (professional tuner) and get it set up for your specific riding style. Done properly it will transform the bike.
