    I'm not aware of anyone who has done this.

    That's interesting that the clutch basket has failed.

    I really dislike Chinese stuff because of their quality.

    But this looks really sweet.

    Shame about the clutch basket.

    @SpookDog Yeah hard to say really. My RS runs at about 60 and my RE can run as hot as 100.

    Some 3bn engines have slightly different inlets, not where the manifold bolts on but inside. The internals have different dimensions that I can only guess is supposed to help flow to the ports...

    You bolt it to the flywheel, then insert the centre bolt and tighten it. You need to of removed the centre nut first though...

    Sheet, my bad! I still think it’s the kickstart throw out gear. If you hold down the kickstart and it doesn’t make any difference to noise...

    I know! Don’t worry! I get uppity when I drink more than 4 special brews 🤪 I was just being a dick 👃🙂 So take no notice of me after 9pm!...

    We all love bikes, 2 or 4/‘s and the variety is a good thing...

    @lllDennis So my rebuild consisted of Stainless as it's cheap.

    I just got all the bolts for the engine from "Raceti" and that cost me £145. So it's not cheap. And I'm sure you can appreciate there are a lot more bolts than just the engine.

    The thing that hurts is when they rattle off! 🤣

    Seriously! That’s not normal is it? I ended up cutting and filing back the right side casing to match the other side...

    So leave the carburettor and oil pump cable alone, the cable from the junction box to the throttle tube is like 50cm long (if that). That's the only one you need to worry about.

    I run a YZ85 throttle tube on my DT.

    If you take it apart, use a drop or so of bearing/thread lock to secure it properly...

    Yea I know, but I have a local shop that’s got all kinds of bearings and oil seals. So I just wanted so see if they had any who fits my engine. Then I don’t have to wait for delivery and etc. But do you know which ones come originally?

    I wouldn’t worry so much. If so keep the pre-mix. Otherwise put the clear tube on, see the flow and trust Yamaha 🙂

    I’ve had similar temperamental problems with this (& a 100 other things!!)
    The only thing it can be is the needle valve that is operated by the floats (or the floats themselves!)old fuel varnish or dirt is the usual suspect...
    You can get a replacement kit I think. The needle and the brass insert it fits into...
    A good inspection and clean is usually good enough...
    P.S. the ‘weight’ of fuel can exasperate the situation, or it has in my experience (which isn’t much!)...
