    I’ve always froze my bearings heated up the hub greased everything up then gave a bit of gentle persuasion, never had any problems the couple of times I’ve done it but that’s a pretty handy trick

    Moral of the story from this I can see is

    More horse power = power maintenance worm with pustion changes probably more regularly

    Keeping the dep exhaust carbon reeds and sprocket changes seems like the best for performance with out risking blowing pistons more frequently

    I did see a video on YouTube on how to make two stroked more powerful but with this there was a risk of blowing the engine maybe if you want a fast bike just get a bigger one?

    I wanted a yz road legal but for daily use I can imagine these get warm and aren't really good for road bikes sure for the track for a couple hours it's all good

    The dtr is a true work horse in my opinion

    @Baileyboy2008 well like Calum pointed out there’s no such thing as pinning your valve half way if the valve is have way closed you will get zero power above 6k open her all the way and then see what it does

    Pressure Cap!

    I wouldn't believe it but I have seen it a few times.

    Always start off with something cheap and look at the more expensive items later.

    Measure across the pick up sensor. Make sure that you are getting current to trigger the CDI. You will want to follow that pulse from the pickup to the CDI. From the CDI you will see it go to the primary coil. From there it should go to the secondary mutal winding and out to the HT lead. It's as simple as that. Somewhere you are losing that signal.

    Well you should have checked the bearings at the same time.

    My aftermarket clocks reset to zero. Now my mot history is all over the place. I don't intend on selling the bike so makes no odds to me. Would be nice to see how many miles I have done in ten years though.

    @panmil92 I don't recall there being any certain type of weak point. Fairly bullet proof motors.

    It's just general items. Bearings, bushes and seals.

    Here it is running...

    Story is it overheated on a ride out due to an airlock in the cooling system. So the piston went pop

    @Calum said in reeds confusion ??:

    @Dingle74 I'm sure there is information on here about what can be used. Try using the search bar..

    good pointe with the searchthing , but the searchfunction is not my new freind :crazy_face: when searching for reeds i get everything from pics of cracked seat to chain and wheel-questions :face_with_hand_over_mouth: so have just skimmed over lightly
    there was one post though sayin that wr dont fit and poster wanted to show a pic of the difference but sadly it didnt work for him
