    Here are the differences in the 3BN Cylinder head [image: 1483566896896-dt125rheads-diffrences.jpg] It'll be marked on the cylinder head. [image: 1663628447669-874e98a1-e604-4e06-9310-d20f77cae655-image.png] The 3BN head is interoparable with the 3MB head, but has a combustion ring which is said to adversely affect performance. Here is a video of the difference between a 4FU cylinder and a Belgarda 3MB00P cylinder. https://www.youtube.com/watch?v=P8okvTxe-Bs Here is a 3MB cylinder. [image: cylinder-1_medium3MB1131100-02_4baa.jpg] [image: 1663628477295-8e899a28-4514-4881-89ec-bfcc824ade10-image.png] You'll see the crankcases are stamped 3BN [image: 1663628512647-b054f520-0af7-4920-948f-cc532b8bbd25-image.png] For the most part you don't need to worry about it, it'll be rare that you'll find a DTR with a 3BN crank/cylinder and most of them will be 3MB cylinders. But it's just worth bearing in mind. There are variations in CDIs and Exhausts which affect the performance, but these are less important as there are aftermarket support that recitfies any loss in performance

    Normally, they just add a throttle stop to restrict the bike, so you can only open it 3/4s of the way. This is what a lot of the test centers do as it's easy then to unlock the bike to full power afterwards.

    @Stevie-Wonder Thanks bud Greta (for that is her name as she's noisy, irritating, aimed squarely at the youth market and responsible for thousands of them bunking off school all over the world) cost me half as much as my '93 due to the mileage and had a thick layer of grime all over due to years of grinding commuting. I gave her a scrub with Jizer (several times) and this is what was underneath Here are the part #s for the toolbox and lid, bit pricey IMO and you'd have to get the lugs welded on to a non-e start frame. Be a nice touch if you were getting it powdercoated sometime though https://www.cmsnl.com/products/boxtool_55v2817301/ https://www.cmsnl.com/products/lid_55v2818500/

    @HOBO4LIFE I know, but I'm saying that if you get an A2 license when you're 19 you are allowed to get the full A license once you're 21 and you don't have to wait till you are 24.

    EXC is a good fun bike, tried one and was looking for one before I got my gasgas 250. Unfortunately people either wouldn't get back to me or would say "Sure come see it on Friday" then phone me up on the day and go "Sorry just sold it". It's very frustrating when this kind of thing happens. Either way ended up with the GasGas and I'm happy with it

    @Mightyman HTC had previously mentioned they planned to unveil the Vive 2 at CES this January but they then announced they won't be. A vive 2 is in the works, but we don't know what it's going to offer in difference. Right now it is convincing that it will be wireless and the resolution of each lense will be upgraded.

    Thanks for the replys. Actually do have a manual and also managed to cure starting problem. It was a poor connection in one the connector blocks hidden away amongst a tangle of insulation tape. Thanks for the help though.

    Lol. Premix ratio for a DT, it does not need a racey mixture. The standard Oil pump is about 45-50:1 ? I ragged mine and found 35:1 to be adequate in the end, I only just managed to briefly heat sieze, with little damage with the oil pump fitted a time ago, and that was flat out for 4 miles! The later 3RM pumps are pretty good, the older design were ones people had issues with.

    Never had a problem with Athena gaskets. They are used on my Starlet necessary when trippling the power output of the old engine. Sounds like either not fitting correctly, or head and barrel not skimmed properly. Fitting means retorquing after running the temperatures.

    @Darty The sad fact about all this is such a wonderful bike, lovingly built and very well restored, will hit the scrapheap well before it's time. And once the dust has settled, I'm sure that the outcome of all this will be valuable experience and a hard lesson learned by @Biker_123. As I'm sure from now on he will vet any potential buyers and protect himself much more in the future!!!
