DT125R FORUM

Forum patched and updated. Fixed some database corruption issues which was having a knock-on effect with emojis so hopefully they're working now.

Hey All! Due to personal circumstances I will be needing to suspend the DT125R Forum for an indeterminate amount of time. This is an advance notice to say that at some point, in the not to distant future, I will be switching off this forum. My intention is to relocate the forum/database hosting as the current situation is no longer economically viable. It is unclear at the moment as to what the future will be for this forum, but rest assured it will be back online in the fullness of time. I appreciate each and every one of you that contributes to this forum so there is a BIG thank you from me. Take care & keep smoking! Calum

There are wiring diagrams and manuals around on this site. Try searching using the built in search. Another great tip is using Google In Google search engine do site:dt125r.co.uk wiring diagram 6 wire and let Google indexing do the heavy lifting.

Float valve height sounds like it needs adjusting.

I can't say I am very familiar with thise pipes sadly. I have been away from the tuning scene for these bikes for many years now. It's been years since I've even ridden my DT to be fair.

Hi all, I'm looking to buy a Yamaha DT125R and I've found one, but it's a DT125RN, model code 4BL, from 1997. I've heard this version is restricted to 80 km/h. Does anyone here know how to derestrict this specific version? What exactly is limited on the 4BL (exhaust, carb/jetting, ignition/CDI, power valve, intake), and what needs to change to remove the restriction? Also: Which parts are needed, and are the originals still available? Any problems to watch for after derestricting (jetting, reliability, piston/cylinder)? What should I check before buying the bike ? Photos of what to look for would be a big help. Thanks in advance!

Also don't forget to change bulb in light cluster for an led Kind regards
