    Drz 400e

    Have you got any peripherals connected, like a USB port? If it's not getting a proper charge, check the connection from the RR to the rest of the wiring harness.

    Reading a 4 stroke piston

    Interesting observation and hypothesis

    Reading a 4 stroke piston

    Thanks, the skirt and surface which was inspected after cleaning with Q20 and a rag, is great shape, no dings, pitting or cracks. My post wasn't because I"m concerned about the piston, I was hoping it would give an indication of my jetting, thinking that a rich mixture would wash the intake surface clean. I am comparing this to previous experience on some other bikes. the difference between the intake and exhaust side has never seemed this stark.

    Reading a 4 stroke piston

    Most of that surface "pitting" came off with Q20 and a ra The piston and rings are in great shape, the skirt has no chipping, and compression is good. What could be throwing you off, and maybe you missed that line, but I went in after a leaky head gasket, maybe that has to do with some of the deposits. Passion oil you say?! I keep that in my side stand, not in my bike

    Reading a 4 stroke piston

    Hi, I tore down the top end to inspect and to replace a leaky head gasket. Everything seems good up there, no concerns over cylinder or piston wear and the cams and valve gaps are all good. I have a question though on "reading" a piston. Right between the intake valve cut aways on the piston, there's a very sparsely fouled area compared to the rest of the piston. I have done top end rebuilds before, but this seems a little different from anything I've seen before. Is there any assumption to be made (ie. jetting too lean) or does this seem perfectly normal? Constructive feedback appreciated. EDIT: I put this here as I believe this is jetting related.

    Of course they would I posted from my phone, attached photo but it obviously didn't upload. 'Ere it is now, I hope.

    DRZ 400sm - Using E exhaust on SM Bike

    Pairing the muffler to an E header pipe will fit the head just fine, and mounts fine at the rear most mounting, but mine didn't line up where it mounts to the SM passenger foot pegs. No biggy, I just made an adapter plate from some scrap metal. Remember to also rejet the carb and do the 3x3 air box mod if you haven't already done it, else you'll be running way lean and it wont reach full potential. EDIT: There is a very healthy DRZ400 specific section here on TT, you'll get PLENTY of help and replies there.

    RR headlight dead

    Thanks, I should have mentioned that I did check the bulb. I found the issue, the middle wire (ground) of the headlight plug had broken off in the plug connecting the headlight wiring to the loom. It wasn't obvious as it was still in place, but after inspecting all the plugs, I came across it and it was a quick fix.

    RR headlight dead

    Hi there, I ran into this problem, and will continue to troubleshoot tomorrow,but maybe someone has run into this before. The bike was standing for a while, and before standing the headlight worked just fine. Today, I got on and realised that the brights idiot light is on, but switching it to dim didn't get rid of the light. I then realised that the headlight wasn't working at all, no brights, no dim. I then unplugged the switchgear to see if the switch is faulty, but even with the switches unplugged, the idiot light still stayed on, but no headlight. Switch is fine. So long story short, headlight doesn't work, and brights idiot light stays on, regardless of the switch gear being connected or not. Any advice will be appreciated

    Speedometer drive hub cancelation?

    No need to replace the spacer, that works fine. Just get a seal to fit from your local bearing supplier.
  12. Except in SA and Oz, there was an E model, but with an S sub frame and speedo. It still had all the good stuff, plastic tank, cam, exhaust, compression ratio, carb...

    2012 400 RR fork oil grade and level

    I prefer motul where ever I can, though beta recommending motul and ktm recommending motorex is only a publicity agreement. Motul is good stuff, should we start a fork oil thread? Kidding kidding!

    2012 400 RR fork oil grade and level

    Thanks for that! The manual says 510grams,surely it would have been a ton more useful if they gave me a measurement in ml/cc and mm. Do I really need to know the mass index of my oil and convert it?

K 4,8 quantity ......................................................................................... 510 g oil level .......................................................................................150 mm oil type ................................................................................
