Spring time= Mod time, Exhaust and Jetting

Recommended Posts

Hi everyone,

This is my first post here but I've been on this website reading for quite a while and now I have some questions. I own a 2008 DR-Z400S completely stock except for the 3000kms on it. And now that the warranty is out and I seem to have run into some money that needs to be spent I would like to start to modify my bike.

I am looking at putting a full exhaust system on probably the SSW/MRD because that seems to be the one everyone is recommending. How loud is that system? I do use this bike to commute on weekends for about 45 minutes so I don't want it to be deafening, but at the same time, I'd like a little bit of noise out of it. Can I put the exhaust system on without rejetting? Of course I plan to rejet too but just curious.

As for putting a jet kit in, how difficult is that to do? and which kit would you guys recommend?

thanks!

Look up 3x3 mod on youtube and follow the directions that come with the JD jet kit, it comes with everything you need including new float bowl screws that you WILL booger up when removing. Any other questions you have can be found by using the search on this forum. Trust me, if I can do it you can too.

When it comes time to cut the 3x3 hole use a 3 inch putty knife heated with a propane torch. It will melt right through the plastic and leave a clean hole and almost no mess to clean up.

Awesome, thanks for the replies. How about exhaust noise? and if I do these 3 mods, how would i be looking for power increase?

exhaust noise Without spark arrestor $ 10.00 quiet insert $ 15.00. is off the wall!! but i love it it was ment for me!!! With spark arrestor and quiet insert im sure you would be just fine. . . power increase lets just say your gonna love it 👍

you won't realize the full potential of the mrd/ssw system if you keep it restricted.bear that in mind before spending money on an exhaust unless you're purely after bling.i run my system open and just wear ear plugs whenever i ride anyway.

unfortunately all good performing pipes are loud.it's just the way it is.

listening to the MRD with ear plugs is like watching porn on mute, it just isn't the same 👍

Sounds like this is going to be a lot of fun, after looking into things here the JD kit doesn't come with a new pilot jet, will I need to buy a new one of those? sorry if that is a dumb question, but I have no idea 👍
