Help me! I just got a new exhaust for my 400 and I also have a k&n filter and vforce reeds, what should I change my jetting to and how do you change the jet?

 

Figured it out myself and I used a 260 main jet, seems to run just fine but it got late and I have school tomorrow, but I'll pull the plug one day soon after I run it to make sure it's jetted right.

 

what was the stock jet size? for future jetting assistance for the size change for the mods you did.

 

Please tell us you didn't put a DG pipe on your Scrambler. You'd be better off eBaying that pipe and getting an HPD trail pipe. Anyways, for jetting, a 260 sounds about right. Pull the bottom hex bolt off the bottom of the carb and the main jet is right there.
