DT125R FORUM

Hey guys
Anyone know what size rim lock for 2005 DT 125

![Hey guys just throwing the bike back together after getting the exhaust holes re-tapped, and I’m wondering if I’m missing parts for the expansion pipe bracket. I want to make sure the pipe is held in securely so there’s less stress on the bolts down at the head. If anyone could send on a pic of their setup that would be much appreciated.

Thanks Oisín

Hi hope ye all are doing well. I was just wondering if anyone ever dealt with MMG racing before I believe they are based in Spain and I’m looking to purchase a cylinder of them but I just said I’d check to see if anyone dealt with them before.
Also would this suit a 2005 DT125r, I was running a 3MB00
This is the link to the cylinder

Hey
I’m looking to get the bike up and running again for the summer and I’m wondering if anyone is selling a cylinder for a 2005 Dt125. Ideally with piston and pv, all good to go.
Thanks guys

So what would ye recommend I do. I can get it bored out but I don’t know if I could get it plated, at least not for too cheap. Would I be better to buy a new cylinder and piston from Alixpress or somewhere like that. What would be the best way forward, looking for some advice
Cheers and Merry Christmas

@markus-w
Nickel plated ok. I bought a rebuild kit and the piston is a fraction too big and I can’t seem to find a smaller one. So ur saying if I bored it out I’d need to replace it, is it ?
Thanks Oisín

Hey guys
I have yz 85 2003 and I didn’t know where else to find this out so here I am.
I’m just wondering what the cylinder is coated, I’d it’s coated at all. As I need to get bored out and I was asked what it’s coated or lined in. So if anyone knows what it’s coated in or anything like that please let me know
Cheers guys

@Calum haha I get yea. And how would one unrestricted it

@Calum yea I ok and how do u tell if the cdi is restricted? I have a DT 125r 2005

Would a pinned powervalve create a loss in power and acceleration? Just wondering thanks

Yea seems to be good stuff would recommend

Just said I'd let u all know I got it fixed.
I used some jb weld and retapped it back our to m8 and seems to be holding now.
Thank you all for your help Oisin.
