Woah sry about last 2 threads horse power and speed they were bugged or something msgs didn't show up. Anyway i just put on my Big Gun Exhaust race series and my K&N air filter and jet kit. I also have my air box vented.I also have big gun rev kit. All this was on my 2003 DS650 baja. I was wondering what could i do to add more horsepower besides new engine or boring out the stock engine. I plan on doing alot to my DS over the next few years so make a big list if u could.



2003 DS650 Baja maxxis razors, Big Gun full system race series exhaust, big gun rev kit, K&N air filter/ jet kit.

2002 Yamaha Warrior maxxis razors, dg front bumper, renthal handbars/grips, FX graphic kit/seat cover, DG swingarm guard, FmF powercorve 4 with powerbomb header.

 

Go over to the Bombardier forum and you will find a lot more information on modding the DS.

THe next step would be to ditch the stock carb for a TM45 or Lectron 46HV with ported intake. I recently did the 46HV/ported intake and it really woke up the DS.
