DT125R ARCHIVE

There are lots of things you can do to make your dtr quicker. i used to own a dtr it was stolen in november the only 125 that could beat it was an aprilia rs which was capable of 130mph, you wont get more than about 105mph out of a dtr . As standard a dtr is around 14 hp, do everything on my list and you'll be on the back wheel in 3rd and kickin out about 30hp. 1) The first thing to do is to turn the powervalve around to open the exhuast port wide open this will let your bike rev right out but you will give the bike a much narrower powerband so youll be reving it alot more to pull off and go up hills.2) A dep pipe will cost you over £200 for a full system but will add on alot of power and make it sound great to. visit http://www.racespec.co.uk  for dep pipes. 3) a K&N air filter is also a must youll prob. have to put a bigger jet in the carb but youll ad on about 3-4 hp and itll sound really beefy to. 4) the dtr is also restricted through the cdi ignition box but only on models newer than 1991 H rej. so if you can find a cdi box off a dtr older than 91' youll add on big hp by changing it. 5) you can also get a set of boyesen reeds to add on abit of power they cost about £30 also from racespec. you can do more small things like rasing the compression n' stuff but youll risk cooking your engine so its not really worth it. so thats about it, do all these things n' youll be amazed at the power gained just like a scrammie.
