DT125R FORUM

@somerandomguy314 Really? I am sure that's not the case, I sell to EU all the time through eBay's Global Shipping Programme. Ask the seller if they'd enable it, it's invisible to them and they just ship it to a UK Warehouse.

@Bilbo9000 Outstanding, I never thought of doing that! Well done Sir

Thank you very mutch, i will be looking for one of the Athena ones. I have managed to get hold of a 3bm head but it is badly damaged on the inside so i will send it back and switch it for a Athena head.

@Sgt-Robuck-5, I have the same scratches but there is also metal in my oil, do you think the metal could be frome the scratches on basket or my transmission?

You'll want to understand why that's happened before restarting the bike. Lack of oil, incorrect piston ring end gap tolerance, or just generally tired engine, etc.

Regarding the CDI I have, I read the same thing, so it's fine. I was looking for Ignitech, which is a little cheaper, but it turns out that in my country imports up to $200 are tax-exempt; you only pay for shipping and the product itself. If it costs more than $200, you have to pay an additional 60% in taxes. Regarding the CDI head and curve, I was asking about possible detonation or some other symptom that might not be very positive or beneficial. I was looking at the RSA 125 head design; I didn't expect it to work the same, but at least it seems like a design I could consider reliable or better than the current one. Everything is quite complicated here in Uruguay: resources, possibilities, etc. Perhaps with a test bench or sensors it would be easier, combined with the knowledge acquired over the years. There's a visa I could apply for; it's somewhat expensive, but it allows me to go to the UK to work and travel for two years. Maybe I could try my luck there. There's a lot of desire, but the problem is the resources available here. Thanks @Calum

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.

@glynn6500 oohh, yeah very hard to source. @scrimsmustang is a bit of a legend for finding things as well as @oldman IIRC. Your best bet is CMSNL from what others have said they are Wizards!

@glynn6500 said in Dt125r 1990 raspberry red: Re: 1988 rebuild update Hi there where did you find the Silver seat cover as I’m trying to find an original cover as the aftermarket covers are crap they don’t cut them the right way for stretching around the curve in the seat. Started rebuild mine back in 2017 complete strip and rebuild everything and replace every nut bolt washer was missing the head so the Conrad was seized solid It had been sat outside for 20 years so you can imagine what it was like.regards Glynn

@BalnAndCantGetUp Update! The site was legit i was just overthinking it I fitted on my bike about a week ago and i did my first ride after 4 hole months yesterday. Needless to say it is a trustworthy site

@fishy-fish I'll put money it's that then.

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.

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

Hello, Im in the very same spot as you, did you manage to get something done?

Yeah, I hear that the bargains at Lidl get great reviews.
