Hey all, I was wondering what size the stock main jet is on a 2002 DS650Baja. I'm going to be going to a FMF Ti-4 pipe soon and am going to have to rejet. I will be running it without the air box lid on and I also was wondering if any of you guys have this pipe. Also how much do you usually go up on the main jet with a aftermarket pipe. Thanks

 

Check out Buttfungus' website he has a lot of info including the jetting different people use. I ride at 5500 ft. and have a 180 main and the clip on the 2nd position.

 

Thanks alot 3Tv, this should help me alot.
