best yoshi for drz 400 s

Hello, my I know what Yoshi is better for my DRZ 400 S?:

- RS 3 for S model with stock S header

- RS 3 for E model with stock E header (or with FMF power bomb for E model, I have both)

- RS 3 full system for model E

- RS 2 full system for model S.

And about rejetting, if is necessary? Thamks, I need information as soon as possible to do the best joice!

Best, havinq a look to the budget!!!!!!

okay, RS2 & 3 for E and S are the same pipe just different mounts and different style mufflers.

Get a full system for your S model :thumbsup:

That will give you the best performance overall

Rs 3 full (for E) and rs 2 (for S) have two very different headers, the first shorter, what may be the reason? And performance? And is necessary to change jets?

How do you know this? I dont believe it to be true.

As for Jetting, Yes it will be needed. Depends on your altitude and carb u have.

I saw that RS3 header was so, shorter and with a shape very different from the stock one, like the header of RS 2 is quite similar to the original, or it seems so. Perhaps I saw an old model? And where is better to buy this ehaust, to have good price whit fast and sure delivery to Italy?

The Yoshi header is alot shorter, as the mid pipe is longer to make up the difference. RS3 and RS2 are the same, just with different muffler styles.

Cheapest and best place to buy any exhaust is the TT store, good service and quick delivery

Thanks, but I have a doubt: also to save money, already having the header FMF PB would be a terrible idea to buy only the slip on E RS3? The performance would be very good also in this configuration, or not?

The FMF header is made to work with the stock muffler(or a slip-on) so it is compromised. The diameter is the same as the stock header, atleast at the joint. If you want the most power for your bike, a full system is the best option. And the Yosh ti is the best of the full systems. All the other full systems are about the same in my opinion. Just pick the one that has the sound and look you like.

If you plan on doing a big bore kit down the road, go with the Yosh ti.

Just bought a full RS-2 system for £276 delivered, very much worth it at the current exchange rate. The company in question put it down as $30 and OEM warranty replacement (so no import tax!).

I just put a full stainless RS2 on my S. I emailes Eddie about the 3x3 and rejet twice. one with RS2 and one without, jetting was the same at 1200' elevation.

It fit on really except that it just touches my UUnabikers.

Ran it for about 10 min the other night and no problems

The "best" is the Ti but it is the most expensive. I like the stainless RS2.

Thanks. But if I found a RS3 for E used (or new but cheeper) may I use wity satisfation? Is it the same for the engine the RS 3 for E and the RS 2 for S?

Is this Used E RS3 a full system or a slip on.

If its a slip on for the E, it will not fit the S header without modifaction (due to difference in diameter)

If its a full system it'll be fine.

RS3 for an E and RS2 for an S are the same pipe, just with different mounting systems.

And also, is better to buy a DJ kit stage 1 an follow the istructions of the kit? Or is not necessary? Thanks again

Perhaps it's a full system. But for the slip on, it works good using the header E stock (or the FMF PB, for E, that I have) , so saving money? Or is very better the full system?

The full system will be better than an FMF header, but if your on a budget then the slip on will be fine.

I would buy the James dean Jet Kit, as its much better than the Dynojet kit. :thumbsup:

Where did you buy the JD kit? I don't know this kit, what about it and the differences fron DJ (and the cost)?

I'm pretty sure the TT Store sell the DJ kit.

The DJ kit has better selection of Jets needles and comes with the correct Pilot jet, which you have to buy separately in the Dynojet kit.

Not sure on cost, as i have never bought one.

you can get the JD kit at the TT store.the JD kit is better only because it comes with more hardware(ie;pilot jet and 2 different needles and allen head bowl screws)the DJ kit uses a needle with much more taper so that you can use a smaller main jet.

      Anyone’s air box smell like gas ? Is this normal ? Air filter is bone dry but it reeks in there .... I’m assuming cause of the carb being semi filled with gas ??

      So I’m reading these horror stories of the stock vacume operated petcocks failing and letting gas into the oil .... how many of you guys switched over and is it worth it to switch to manual ?

      Hey guys . I feel like I post here way to much lol 
      anyway after having my bike kn it’s side overnight to fix a cracked stator cover .... I come to find out that I also accidentally left the pet cock in the prime position .... constant gas flow to carb ... now my oil smells strongly of gas ... my question is ... was it the bike being on its side that made the gas get into the oil or the prime position on petcock that made this happen ? Or both ? I didn’t ride it much at all after discovering... I assume. I should drain the oil obviously but any other suggestions ? Always appreciated -mark
