    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/

    @Calum DT's have rocketed up in value, and not many 16-17 year old's can afford them. A lot of them are bought as mid life crisis's from when they were 17. And most 17 year old's with good money will go out and buy a KTM 125 EXC, much more bike for £1,000 ish more than a DTR.

    @bakerDT125R-SM There's usually some to be found on ebay as well, which may prove cheaper? You could also join the Facebook groups and ask on there too, see here for details; https://dt125r.co.uk/topic/562/parts-suppliers-database

    @Bananper Yeah that sounds fine. You are meant to bleed the pump from the oil pump itself. There is a nozzle you use to bleed from. so unless something went wrong you should be okay.

    @jamesrandall93 Yeah, I think you're missing the point I'm trying to make. If the fueling isn't setup perfectly, that's where you will encounter problems. So if it's modified and hasn't been rejetted then reliability will suffer. If the bike is in stock trim (ignoring the DEP) and the engine sounds sweet, then you can greenlane on it all day long without engine troubles.
