As I promise,this is a picture of new exhaust for my Van Van!
It is a Kucelj exhaust (Croatian exhaust).
I noticed better performance,steering faster and sound is pleasent strong.
I am compleatly satisfied what I get with that exhaust!
Next change is a air filter and piston carb.I dont have manual,so if someone could tell me about measure of originale carb piston or measure of piston for better performance!Thanks ! :-)

I have also looked at tuning parts from the USA Suzuki DRZ125 but i don't think they have a TPS (throttle position sensor) so carb's may not work on the van van?

Thanks Karl,you were helpful! :-)

So if I choose to put some sprint air filter and wider  
jet(more gasoline),does anyone know which proportions of that changes are ideal?

After all that ,is it necessary to adjust throttle valve (air)?

Of course,thank you in advance..

I wish you all lots of km on your bikes :-)
