Hey, ive got a DT125X, ive done the wire behind the speedo, and got a full dep exhaust pipe, and took the snorkel off the air box under the seat. All together they have made it considerably quicker! I've heard, it's then good to change the jets to bigger ones. Any idea of what's the best size to go for? And also the reed valve. I'm not fully up to speed with reed valves, i've never had one in my hands to look at. Any advice on whick is the best ones to get and where from? Thank you people, and god bless this forum for being full of genius'! lol

Here is the standard reed and cage

I fitted boyessen 2 stage reeds to mine

Here is the standard inlet manifold

Lots of people are led (wrongly) down the path of chopping off all the rubber moulding that enters the reed cage, myself I just chopped some off and left some on as it is used to direct the fuel air cleanly to the reeds...this is what I did

as for main jet...it would be wise to jet 10 points higher, for example from 240 to 250

Do you know that if this forum was "The Matrix" then OG would truly be the Oracle
