Hi all. I was just wondering how the 1997 DT's are restricted? What can I do to get it full power? I've changed the exhaust for a full DEP system (in the process of fitting) what else is there restricting them? I can't find anything on the 1997 models for restrictions?

Searched this, may have even asked this before when I previously owned this bike lol. Basically my bike just runs out of steam at about 8.5k rpm or so. I know it's only a 125, don't expect it to be that quick but the power band just feels really short, surely if it says the redline is at 10.5k or whatever it is...
