DT125R FORUM

Right, ty for the advice.

I mean "increase air intake" was the duct tape on airbox like hole under the seat ment to be there or was that added after because i didnt do that and it seems logicly to increase air intake with full exhaust but i wont like drill holes in the airbox or something like that just remove the duct tape.

Because i see alot of people having 230-240 jet on the bike with aftermarekt exhaust that makes me want to change the main jet.

Im from Slovenia i tank 95 gal mix it with Motul 510 2t so you think there will be no need for main jet to get changed?

About the intake im thinking of removing the duct tape on the airbox (it covers half of it) so it can take more air.

Im on a normal atmosphere like 100m or smth, the point is that the exhaust will be made from a guy who i know from Akrapovič it will be handbuilt and made for preformance, makes me think that i will need a bigger main jet then.

Hi fellas wondering if anyone knows the main jet size for aftermarket exhaust on DT 125 RE 2004 stock is 210 i have 240 on my mind.
