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!
