Staintune Exhaust - what needs to be changed?

[hannesf]

hey there,

i am pretty new to the xtz660 and just got mine half a year ago. I now did 15.000km on it (a part of the trip is here: https://youtu.be/qoJh2URDtGc) and my original exhaust was rusted so badly, that i had to get a new one.
The one i got is a Staintune exhaust from australia for the XTZ660.
I am now thinking what else i might have to change in order to get it to run properly. With the exhaust i bought a K&N air filter, but i a have no idea if or how i should change the jets! Right now i am using stock jets and stock needle position.

So main question:
- is there any recommended jetting change?
- any recommendet carb change (setting)?
- does it make a difference with or without the DB-Killer (setting wise)

Cheers and thank you so much!

I've you want to get it spot on the easiest way is to book a dyno and get your carbs rejetted. Aftermarket carbs are possible, but with those mod's I'd say a too expensive option. If you know what you do you can rejet your carbs yourself, but this will mean a lot of fiddling. If there is a Dynojet kit (or similar) available for your bike that would also be a good option, as some of these are designed for standard engines with free-flowing exhaust and more open air-filters.

Hi Bowler, which one of those options gives you the best bang for the buck so to speak?

Ok, here is what i did:

I installed the Staintune exhaust + K&N airfilter and just left the Stock jets in place... The Bike runs really really good.
So with DB-killer installed there is no need to change anything in the carb...
