    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/

    @Steady-Eddy I would love a C90, they're starting to become a collectible themselves. You got any photos of the C90? Yeah, it always sucks parting with vehicles.

    @Mightyman same here. The number states the temperature "level" of the plug. The colder - higher number. Im heard the colder spark is better ...

    So to confirm, if we could hold off on the hall of fame idea for now. When I do release it, it will be some new functionality where it will be linked directly to your profile on a new home page where it won't just be members who can see it. I will keep you updated.

    Any things can be done if your willing to spend the money. I haven't done that but I have a yz125 engine in a dtr frame. I needed to sort top and front brackets.

    Makes me sick!!!!!!!! My lock up has 3 alarms, I also use alarm disk locks front and rear and have the bike chained and padlocked to a anchor cemented into the foundations of the garage. On top of that I have a sneaky rape alarm boobie trapping the garage door lol. I once had a dt125x back in 07, I wernt so cautious back then and lost out to a thief!!. Im sorry for your loss bro Scumbags man
