DTR 125 new piston ?
-
Today I was riding home when my dt lifted, then went back down (without any loud noise, bang or anything). After that my bike has now got extreme amounts of pull, what feels like a very small power-band at the most and sounds like that of a 4 stroke engine, the bike sounds deeper and the engine feels a lot softer than it used to. Could this be a sign that I will need a new piston or could it just be an air leak ?
-
Also, the bike only gets up to 8k revs, feels like the powerband kicks in at about 5k instead of 6k and sounds nothing like a 2 stroke,
-
@Calum I believe so. It's the same power band that has been installed for the last 1500 miles (in which it has been running fine) the bike has also lost the signature "brap" a 2 stroke usually has.
-
@Calum There is no rattle at all, could there still be a possibility of a new piston ? Or could I just need to re pack my end can ? As the bike was bought second hand with the exhaust system already on it I cannot tell you how many miles it has been used for.

@Blaze-Vile Just take the exhaust off and have a nosey. Literally 10 minutes and you'll know if it needs a new piston.
-
@Calum okay, just look for scratches on the barrel and wear on the piston ay ?
-
@Calum I've felt around the connections and I couldn't feel a leakage, No scratches on the piston or barrel either.
-
@Calum The servo still moves it when the ignition turn on however the powerband opens up earlier than usual.
