    What big bore is this??

    Just picked up a used 2005 DRZ400sm last week. Previous owner said it was a big bore. Anybody know what make it is? Also, the bike has a full FMF exhaust that backfires a lot when rolling off, just wondering if there is an easy way to tell if the carb was re-jetted before I buy a jet kit.
  2. I rode around a bit reving it out then made a final hard pass before i removed it.

    1980 kdx 400 HELP!!?

    So ive recently had my main clutch basket nut and the crankshaft nut come loose and I've finally fixed that. Now ive noticed a slight ticking noise kinda like a piston slap it sounds like it's coming from the top end and when i took the head off theres a part of the head that is clean metal and no carbon so I assume its that, I couldn't feel alot of play in the bottom end bearings but I didn't take the cylinder off, i just pushed down on the piston, new head gasket is on its way. Should i run it how it is and what would i have to replace to get rid of the noise or should i sell it? I don't have a ton of money to dump into rebuilding this thing as im only 16. Thanks for the help!!

    DRZ 400 Rally

    Hi everyone, I am curently building my bike for light adventure riding. I am making a contraption that I would like to call a rally fairing. I am showing you what I have made so far. For the build; - oversize GPI racing radiators - oversize gaz tank - fuel pump - swapping the speedometer by a vapor - custom made bracket for fairing - fiberglass fairing/windsheild I have not adressed the wide ratio issue since I just completely rebuild the engine last winter. I got a 39 teeth sproket for highway speed. I have no experience whatsoever with fiberglass, any input would be apreciated. Thanks for the interest.

    E/S Model Outer Fork Dimensions

    As the title says. Everywhere I search only gets me the inner fork dimension of 49mm, but I need to know the dimension of the lower portion that the top inner fork compresses into. My best measurements get me 56.6mm. Image showing what I'm talking about. Anyone know?
  9. Thanks for taking a look. I hope someone can point me in the right direction to get this headache solved. I'll try and be as detailed as I can without bombarding you all with a wall text.. My bike is a 2005 DRZ400S with over 20,000 miles on it (mostly highway but lately more dirt). I just recently brought the bike in (after a good 3 hour ride in the mountains) to a local motorcycle service shop (Cycletune in Portland, OR). They did a list of maintenance work as well as replaced the tires, relocated my ignition switch, removed side stand switch, etc. I took the bike back home and it died after about 15 minutes on the highway. Now, my bike is experiencing intermittent loss of power, backfiring, stalling, etc. The mechanics working on my bike threw up their hands and told me they tried and couldn't figure it out. They said they did not believe that they caused the problem and did not know what was causing it. They said that they could "start throwing parts at it" and charge me hourly to try and figure it out... Before my bike died on the highway and was towed back to the shop, I got their "level 3 service" (highest service package available). This service included: Oil and filter change, Battery check, Wheel & tire inspection, Cooling system check,Inspect/clean air filter,Lube/adjust all cables and pivot points,Clean and adjust chain/belt,Inspect brake system,Check electrical system,Inspect clutch components (external),Fastener check,Set tire pressure,Safety check,Spark plug replacement,Carburetor/throttle body synchronization,Inspect/change transmission fluid/driveshaft fluid,Inspect steering head & wheel bearings,Cooling system check & flush if needed,Brake and Clutch,fluid flush. After they took my bike back in and couldn't fix the intermittent problem, they gave me a handwritten letter saying the following: "Level 3 service was perfored. All fluids changed. Valves checked (within specs) side stand switch eliminated. Bike had intermittent stalling problem and was towed back to shop. Problem was eventually replicated on test ride. Intermittent cutting out, loss of power. Eventual stalling was experienced. Fuel petcock was checked at the time of stalling - appeared okay. Correct level of fuel was found in float bowl at time of stalling. Pick up coil was replaced. New pick up coil did not solve problem. Intermittent problem still exists." Here's a sound clip of the problem (it starts around 0:14). Bike was warmed up for about 10 minutes before the audio was recorded. The bike idles just fine. Any ideas on what is causing this? I'm somewhat mechanically capable so I'm going to try and fix it myself (partly because I lost faith in the shop I went to for a variety of reasons and don't trust that they will fix it and partly because other local shops have a wait time of 4+ weeks to get my bike in). Thank you!

    Timing Chain Links

    Rebuilding top end of my 2004 EXC 400. Now onto re-riveting the timing chain but having some problems. 1) it looks like I 'broke' the chain incorrectly? I've managed to remove this section: Opposed to this section (new replacement riveting link, (I bought 2 in case a damaged one)) I was hooing to just use the old pins and re-swedge them but the old pins will not fit in the links in the chain now (by hand). The pins will not push into these link holes.... I thought I must have distorted the ends enough when removing that they no longer fit but then I tried the new riveting link in these same holes and they don't fit either! Then I tried pushing (again by hand) the new riveting plate to on to the new riveting link pins (plate see resting on top if the pins below but that also doesn't fit.... So am guessing plates have to be pressed back on to the pins (old or new pins). Is this correct? Given the way I 'broke' the chain its going to be very tricky press the old pins through the chain, though the section I removed and in the plate. I'm using the motion pro chain riveting tool... Any advice/thoughts welcome. Far too many tiny bits to juggle and not drop in the motor! Have I buggered it by removing the section rather then riveting link supplied as replacement? Hope that all makes sense. Thanks in advance. Dan.
  11. My DRZ has been very slowly becoming harder and harder to shift into neutral. Sometimes it just won't. I shift all the way down to first, and try to half upshift into neutral, and it's like i'm pulling my foot up on a solid object. I just cannot get it to upshift no matter what. When i'm rolling it seems to shift easy, but stopped is a NO GO. I just did a fresh oil change today. (Somebody said an oil change fixed his no-go neutral bike). Can somebody please help me out here? Give me some ideas maybe from 'Probable the issue' to 'could possibly be'. And i'll go down the list and try to get this solved. Thanks in advance peeps.
  12. Hi guys! I own a DRZ400s and have a question about taking a different approach to the standard leaky petcock Fix. So, I just ordered the fix a lot of people recommended on here for the leaky stock petcock: The Petcock off of a Yamaha Raptor. I did this after looking for other vacuum petcocks and not finding good alternatives. However, I found a part made by Pingel, and was wondering if it would work in conjunction with the Yamaha Raptor petcock, in order to give me the perks of the Suzuki Vacuum Petcock, without it's shoddy craftsmanship and limited life. Could one of you guys help me out, and tell me if this would work? Do I just place the Pingel Inline Vacuum Valve on the fuel line between the Raptor Petcock and the Carb? Or does the Pingel Valve work as a petcock all on it's own? Thanks guys. Besides hitting the dirt often, I am trying to use my DRZ to zip around Los Angeles and make deliveries with postmates/grubhub/etc, so I would not like have to shut off the manual petcock every time I hop on/off the bike. Thanks again guys!

    2002 400 Exc height

    Hello and new to dirt riding. I just bought a used 2002 400 exc-r and as a newb I find the bike extremely high for me. Had the sag adjusted and that helped but damn I can barely put my feet flat and on the trails it makes it feel so off balance because my feet don't touch and then I loose my balance and of course fall over. 4 times I dropped her yesterday in the woods... ha.. the suspension is plush but i feel too high any tips on maybe lowering it or better balancing tips? I am 200lbs, 5'11". Thanks, Crazycarl012865

    DRZ Condition, What To Expect For Longevity?

    Hello all! I am looking into traveling the Trans America Trail on my DRZ400E. Starting in Rhode Island, ending in Southern California; returning East on RT66. [~6'000 miles dirt, and then ~4,000 miles road return trip] 2003 DRZ400-E ~6k miles: total on bike - 5k miles: lightly ridden, never seen dirt - 0.7k miles: %100 hard off road [past year] Frequent Oil changes, Air Filter changes {again, well maintained but ridden hard the past year} Front and Rear Suspension rebuilt, carburetor rebuilt all last year Stock everything except FMF power bomb header and exhaust muffler, and Vapor Trail Tech , lights + fork socks Expected Maintenance: Top End Rebuild, Timing, Valves adjusted [Have not done compression test, but i would expect new top to be necessary] obvious things such as Brake Pads, Fluids, Chain/Sprockets, Tries, Heavy Tubes Does This Bike Seem Worthy Of Such A Trip? Or am i better off selling to find a newer model?

    Side to side play on a piston?

    So after listening to a tinging noise in my top end for a few days I pulled it apart finally the piston has alot of side to side play on the rod, the bottom end has a small amount of side to side and no up and down, is it normal for a ton of side to side play in the wrist pin area, its an air cooled 80' kdx 400. Also im not replacing the piston/rings because it had plenty of compression/lack of availability is there a break in period for the needle bearing/wrist pin?

    Low Compression

    Alright TT Gentlemen.. I appreciate any and all who have commented on my posts, without TT and the knowledgeable people in it, things would have taken me much longer. Anyway, I was shimming my valves the other day,before I did it when I checked the clearance.. There was none. I couldnt fit my smallest feeler gauge between any of the valves and the bucket. both on intake and both on exhaust would not fit. I checked my compression before I did this, and it was only at 60/70 PSI which I know is far too low. Before I tear into the engine, I want to get everything I need.. so if A new piston is in store then so be it.. But would valves that have far too little clearance at TDC cause low compression when cranked? Thanks again guys! - Brad
  18. Been riding my XR hard for a few years now and have not shown it the love it deserves. Simultaneously, I'm a junior M.E. student and the South Dakota School of Mines has taken everthing but my bike. That said, I'm looking for a used Aloop kit or any parts thereof that anyone is trying to get rid of. Also ISO 36mm pumper carb for about half of what XR's only has them for. Any other input/leads welcome.

    Buying a DRZ 400sm

    Hello there, In about a week, I'm gonna buy myself a DRZ 400 SM 2005 model with about 10 000 miles (16 000 km ) on it, and i was woundering if any one could help me with pointers i could have when i check the bike, like common faults or similar stuff to look out for when test riding etc etc. It's gonna be my first bike, so all tips are appriciated!
  20. This is the cylinder to my 1980 KDX 400 A2. I can't decide if its plated or sleeved, a magnet sticks to the inside of the bore but i saw someone say its eletrofusioned with molybdenum so it could be the coating that's magnetic.... it still runs with compression but i hope to sleeve it this winter with a steel or iron sleeve so i can bore it as needed.

    KTM 2-stroke Overheating

    I'm caught between a rock and a hard place. My 2010 KTM 250 XC won't stop peeing coolant out of the overflow tube. I've used 3 different radiator caps (two of the oem 1.8 bar caps and one CV4 2.0 bar) and it still continues to pee coolant as soon as the bike starts up. I just recently bought and installed brand new radiators [GPI on eBay for $88 (the seem fine just the welds are a bit crappy and you can see inside of the tubes where the metal from the welds drooped down but there are no blocks)] and silicone hoses (profactory hoses) thinking they were the problem since the old radiators were bent in like bananas. To my dismay that was apparently not the issue. I've had everything apart and looked at. Has brand new base gaskets, head gaskets, radiators, and radiator hoses. I've bled the radiators like the manual says and there are no bubbles like air leaking into the system or being in the system. The jetting is also perfect. The only thing I haven't changed out is the oem impeller in the water pump but it looks to be in great condition. Any ideas on how I can fix this problem before it gets worse? Also, has anyone else had this problem and figured out how to fix it? I ride it in mostly tight 0-10 mph trails and also some 10-20 mph trails.
  22. Most of my videos are on my Honda, but I made this one on the DRZ. A pleasant rural ride in southwest Missouri. I also have a video on my mods and on some off road roading. My youtube channel name is Oklahoma Hank.
