    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

    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.

    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

    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. Hey thumpers, I have been looking for info on high hour/mileage motor maintenance, and to my surprise, apart from Catfish's oil gears bombing, I haven't found any info on these motors going bad. They are pretty new motors, sure, but having been around for 4 years I was expecting at least some threads about engine wear. Please post details on your bike as I do below, so we can establish how these motors hold up in varying riding conditions. Model: 2012 400RR Hours/Mileage: 290 hours Around 7000km/4350mi Riding conditions: Previous owner - Rocky trails (Reason for needing a nw clutch) Me - Mixed trails/dual sport 90 dirt/10 road with 60mhp+ cruising Work done: Valves shimmed (from zero) 10 hours ago New clutch pack 10 hours ago Oil pump gears replaced by previous owner (unknown hours at time) So far, they seem pretty bullet proof!
  13. 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...
  14. I'm looking for some info on how the forks on a 2012 400 RR would be setup stock. The previous owner messed with it a lot, and despite returning to stock settings as found in the manual, I do not know if he had put heavier oil/more oil in and I have the feeling he may have put stiffer springs in. Currently the back of the bike rides lower in the rear than I like, even after bumping the preload quite a bit, and it feels like the fork isn't settling. I tend to need to pull myself forward on the bike a lot which tires me out, and also it's hard to get the front wheel to rail without pushing. A very experienced friend rode it this weekend and made the same observation. I'm gonna dump the oil and put in the stock level of the stock grade and take it from there, so if anyone knows what these numbers are, that would be great. Thanks, Nellis

    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?

    2012 400 RR fork oil grade and level

    I found a more complete manual on betamotor.com (as opposed to the one I got on betausa.com) and found the follwing: “Sachs” hydraulic upside-down fork (Ø48 mm shafts) Fork oil capacity: spring ............................................................................................ K 4,8 quantity ......................................................................................... 510 g oil level .......................................................................................150 mm oil type ................................................................................ FUCHS 1091 My humblest apologies

    WTB OEM handlebar switch

    This one perhaps? http://sicassracing.com/store/switches/universal_switches/sicass_universal_multi-function_bar_switch?cPath=105_35_39& It woulda been nice if they had a specific one that plugs directly into the beta harness like they have for the EXC.

    WTB OEM handlebar switch

    I'm also looking for this switch cluster, please post a link to it if you find it.
  20. Whaaaat!? 23k miles on only valve adjustments, oil and filter? That's some decent haulage, mine is barely broken in then =P Where did you get those alu pump gears?

    Beta parts wanted

    Hi there, Since the Betas come with all road gear, surely some people must have removed the following that I need: 1. Tail light (for a 2012 model but i think 210-2014 will fit), that's the plastic and light 2. Indicator switch. Just the part that can screw off and unplug, not the whole switch cluster, but if you have the whole cluster, let me know anyways. 3. Kickstand Please let me know if anyone has any of these available, Thanks

    What has Broken in the engine

    Sorry to hear about your misfortune, please keep us updated on the repairs.
  23. I found that out the hard way... Any tips on removing once broken off?

    Checking Valve Clearances

    Well admitting to the problem is the first step toward recovery My general riding conditions are mostly moderate speed at sea level, but we have a very humid sub tropic climate, I dont know if that contributes to the heat. While it does get noticably hotter than my other bikes, it doesnt seem like it spews coolant, so I assumed it is operating within the normal temperature range it was designed for.
