    Another excellent video, especially the tip about cleaning out the blue lock tight 👍
    I managed to torque the bolt by sitting on the bike with my right foot on brake and using my left hand on torque wrench , this stopped any wheel rotation.
    Motion pro also make circling pliers that makes the job easy and prevents any swearing 👍😀

    Great video. You can also toss a rag into the chain as it runs onto the rear sprocket to lock the rear wheel. Works great when you don't have a helper.

    I find using a block of wood between the frame and sprocket works really well when loosening and tightening the sprocket bolt.

    Very informative video! I didn't have anyone to press the rear brake for me, so used mole grips to clamp the brake pedal to the stand. Worked perfectly, job done easily with a breaker bar.

    • @TokyoOffroad
      @TokyoOffroad  6 лет назад

      Yes, ff I'm on my own I use a large g-clamp (from the rear brake pedal to the stand). Works well, but you do need to be careful to not overtighten it and damage the pedal.

    Great vid as always... and, Pro tip, for frequent countershaft sprocket changes..ie from one race to another that calls for tooth count changes for gearing advantages, torque the countershaft bolt to recommended spec and smear some RTV sealer over top of the bolt and sprocket to ensure it won't vibrate loose or back out. Then its a snap to clean/scrape the RTV off and back the bolt out and repeat for the following week. Although I wouldn't use this tip for "set it and forget it" applications.

    Thank you for the video. I have a 2017 Husqvarna TE250 and was very glad to see that KTM got rid of the old circlip design in favor of this bolt. The circlip didn't put any pressure on the countershaft sleeve, causing premature seal failure and oil leaks. I do have an unrelated question just out of curiosity, how did you end up in Japan? Do you plan to live there permanently?

    I like the tap trick. I didn't do that on my old 450 that had this set up. I was getting leaking around the seal. The dome washer was not putting enough pressure on the sprocket to keep the spacer and o-ring seated at the bottom of the shaft. I still running the older style clip on my 300 so not an issue.

    • @TokyoOffroad
      @TokyoOffroad  7 лет назад

      I often use a tap to clean out old Loctite from internal threads. You need to be careful that you don't cross thread the tap and also hold it inline with the thread, or you could cause damage. Another method is to use a pick, but it'll take a lot longer.

    Looks like the Moly 60 paste is discontinued. I know you mention finding others, however, how important is the 60% moly content? Lots of debate on paste vs grease so a bit confused.

    • @TokyoOffroad
      @TokyoOffroad  5 лет назад +1

      Dan R- I’ve only used Moly 60 and still have a lifetime’s worth left so haven’t given much thought about alternative options. It does work well and I haven’t noticed any wear on the countershaft. My recommendation is to use whatever you can get hold of. It’ll certainly be better than using nothing.

    Would marine grease be ok to use instead of your moly 60??

    • @TokyoOffroad
      @TokyoOffroad  3 года назад +1

      My recommendation is to use Moly paste. It's specifically designed for this type of application (spline, high pressure), Marine grease would be better than nothing, but won't offer the same level of anti wear under pressure.

    do the 50/13 sprocket combination still works good on the pavement? I understand you can do wheelie on fourth gear?

    • @TokyoOffroad
      @TokyoOffroad  6 лет назад

      Yes, 13/50 is OK on the pavement (top speed on a 250 EXC is about 120kph). Yes, 4th gear wheelies no problem. But I select my gearing for performance off-road. If I was riding mostly on-road I'd use 14/50. Really depends on the type of riding you do and bike. A 500 EXC-F will do 160kph with 13/50 gearing...

    • @wildone2163
      @wildone2163 6 лет назад

      thanks, I have 500 exc '17 with stock gearing 14/45 and for now I have plenty of power anywhere, at least more then I can handle :) But 13t was included from factory so thinking about changing, regarding rear I am considering 48 or 50t.

    • @TokyoOffroad
      @TokyoOffroad  6 лет назад

      I had a 2013 500 EXC and used 13/50 gearing.That worked great for off-road. Yes, would definitely recommend changing your front sprocket to the 13. and see how you like it.

  • @NirHason
    @NirHason 5 лет назад

    I must ask if you don't feel that there is an annoying gap between the 2nd and 3rd gear? like you wish that the 2nd gear was longer so you won't have to play ping-pong 2-3-2-3-2 haha...
    If I'll switch the front from 13 to 14 I'll get a longer 2rd but it will reduce the bottom power dramatically for slow technical stuff? (I'm with the stock rear sprocket so I guess it's a 50).

    • @TokyoOffroad
      @TokyoOffroad  5 лет назад +1

      Recently I’ve been running 12/50 gearing and really like it. Gears are closer and I use 2nd gear a lot more now on gnarly stuff. Definitely worth trying if you don’t mind giving up some top speed...

  • @EeeBeee2
    @EeeBeee2 6 лет назад

    Washer will have a bit of give regardless of bolt tension, due to design.

    • @TokyoOffroad
      @TokyoOffroad  6 лет назад +1

      Yes, it's a conical washer (belleville) which acts as a spring. The washer tension will change with bolt torque. To minimize potential issues when changing the sprocket, which may include excessive spline wear, counter shaft oil leaks and bolt failure (either working loose, or snapping), I highly recommend cleaning the countershaft internal threads, use a new bolt and washer, apply Loctite and torque to spec. Using some moly grease like I showed in the video is a good idea to minimize wear between the sprocket and spline teeth.

    • @EeeBeee2
      @EeeBeee2 6 лет назад +1

      The bolt has a ''step'' in it for the washer to sit, so even if you over tighten the bolt, the washer will still have less tension than the bolt.

    • @TokyoOffroad
      @TokyoOffroad  6 лет назад

      carlin hicks - The issue which I was trying to highlight is that if you don’t clean the internal threads out the bolt may reach torque before the shoulder of the bolt makes contact with the end of the counter shaft. As such I highly recommend cleaning out any old threadlock from the internal threads (use a thread chaser, or tap very carefully) and use a new bolt.

    really dont get why KTM engineers havent put the sprocket on a circlip lock...

    • @TokyoOffroad
      @TokyoOffroad  7 лет назад +1

      Up to 2016 2-strokes used a circlip. The main disadvantage I can see is the the circlip allows dirt to easily enter between the sprocket and counter shaft, possibly leading to accelerated wear. The bolt and washer method, although more difficult to change minimizes dirt ingress and holds the sprocket firmly.
