  1. Proud owner of a 2001 DRZ-400 E model. I don't get to ride much due to work and life, but last summer I decided to race a season of Enduros on my DRZ just to see if I could. Boy was I in for a rough awakening, but I was able to complete 6 hard enduros, and actually placed in my class in individual races and overall. I even beat some of those orange bikes on numerous occassions. The DRZ performed very well overall (a bit heavy, but I don't know any better ), and I got many compliments from other riders on how well it did. However, it took a beating (and so did I, broken foot in last race but still finished ). The plastics got destroyed, and I think 10 lbs of permanent mud is stuck in all the crevices. Haven't ridden since the last race, and I'm just now getting around to checking all the mechanicals out, and I have a question I cant find an answer to by searching. Cam chain - I have an MCCT installed by previous owner. I've always noticed some noise coming from the right side of the engine. I was going to check valve clearances, and noticed that the cam chain seemed to be a bit loose. (it is not tight between the cam shaft sprockets). The MCCT seems to be turned in pretty far (not much travel left, maybe half inch). I wondering if you think the chain needs to be replaced? How can I tell if I need a new one? Do I have to replace the cams, and sprockets as the manual says along with the chain. That would be way expensive. Can I get away with just replacing the chain? How far can you adjust the MCCT before you can assume the chain is done? What other parts will I need if I go to replace the chain? A gasket for the right side case? Anything else? Is this hard to do? I plan to replace the clutch (which I think started to slip in the last race), adjust the valves, new cam chain (if required based on responses), oil change, coolant change, through cleaning, new plastics/graphics, and get back to riding. The bike will now be used for recreational trail riding, as I got the racing bug out of my system. I will try to post a few photos of the bike in action if anyone wants to see. Thanks in advance, Zack
  2. I also have one other issue that maybe we can tackle while we're at it. Sometimes, after I ride through some fairly deep water (up to footpegs or so), the bike will stall on me. When I try to restart the bike, it will turn over, but struggle to start. Almost seems like I don't get a spark. Once the bike dries out, it starts up and runs fine. Just takes forever (30-45 mins) for things to dry enough for it to run. Anyone have any idea what might cause this. Electrical connection somewhere maybe? Thanks!
  3. 2001 DRZ-400 E Model Symptoms: Fuel leaks from carb overflow tube with petcock on, when the bike is not running. Fuel will stop overflowing while the bike is running. Starts overflowing again once the bike is shut off. If I haven't ridden the bike in a long time (months) the carb will continue to overflow even while riding, but this will stop once the bike gets ridden for maybe 15-20 mins. It always overflows when the bike is not running. Any advice would be appreciated. Does anyone know what needs to be fixed/modified/adjusted within the carb to stop this issue. I'm not a carb expert. I took it apart once and cleaned it, and followed the clymer manual to make sure everything was set correctly. Maybe I missed something. Hopefully this is easy to diagnose. Thanks a lot! Zack
  4. The carb is the stock Keihn 39mm FCR.
  5. I just bought a 2001 DRZ400E. I have some questions about jetting. I will list them below. 1. What should my jetting settings be? I live in southern michigan. Elevation is around 300 feet i think. Temps are around 80F right now. The bike has the JD jet kit. The main jet is a 160. Not sure about the rest. Will tear it apart to find out. 2. I took the carb apart a couple days ago to clean. When I did I noticed there was no o-ring or washer beneath the pilot air adjusment screw. Should that be there as it states in the clymer service manual? 3. I have been having a hanging idle problem. Everything is clean now but the problem still exists. What could be the culprit? 4. Carb cleaner slightly ruined the diaphram for the fuel pump on the bottom of the carb and the o-ring there too. Ordered new parts but what would this affect in the short term? 5. Basically what is the best way to set up my carb for my conditions. Thanks for all the help. Zack

  7. Hey, new to TT. Just bought a street legal 2001 DRZ400E. Bike seems to be in great condition and runs awesome when i'm really on the gas. However, the bike seems to have an issue with idle, and running at low rpm. When I pull in the clutch the rpms seem to hang up high, and take a while to drop down to idle. If I turn out the idle adjuster as low as I can before the bike dies, I can sometimes get the rpm hang up issue to go away. The bike just doesnt seem to run smoothly at low rpm. Note: The owner didn't ride the bike much in the last 3 years. It had older gas and the carb may be gummed up. Could this be the issue. It seems to be getting better now that ive been running fresh gas through it. Also, any good (cheap, easy) mods to do to the bike? I know it has a JD jet kit, manual cam chain tensioner, and stiffer front springs. Havent done the 3x3 mod. Should I? Could the jet kit cause my problem. I appreciate any help. Thanks a lot! Zack
