Not sure if this helps - did Cooktown - Tip - Daintree with no change as I felt that fell in the 5000km type of conditions. At home most of the stuff is in Kenilworth/Beerburrum so I work on 1500km on the theory that oil is cheaper than an early rebuild.

Can't seem to find what I'm looking for...

My new to me WRR has a FMF Q4 and Powerbomb header. I'm gonna put stock exhaust back on.

a) leave powerbomb on? Any gain over stock header WITH stock exhaust?

b) take powerbomb off and put stock header back on?

If there is no power difference, I'll likely remove both. More to sell for farkles I really want. If there is a power difference, I'll likely keep the powerbomb on. Goal here is a quieter bike, not a couple hp.

Thanks.

I can't help first hand, but mine is stock and it is fast enough for me. It is also quite.
I read on the 250 forum and some people did not notice a difference while others said they did.

It is kind of up to you. If you want less mgp, and a load noise, and maybe a couple of hp, go for it.
The only way you will feel a difference in my opinion, is to go with a total mod, including a larger jug and piston. jmho

I had a PB and stock pipe that I opened up a bit by drilling out the flat baffle you can see if you remove the tip and look inside.
I'd say a bit more poop than the stock header but nothing to write home about.
I also had a stock pipe with the cat section removed. It wasn't much diff at all.

That said, your best bet is to do the whole FMF mod or not at all.
Q4, PB, and controller. On my friend's stock bike with the airbox door removed, and the FMF package installed, bike ran almost as well as my Athena kitted bike, but without the vibration...

Bone stock and constricted the bike is pretty tame.
Opening up the airbox is a good thing, but most of the noise on a WR comes directly from the airbox, right up into your helmet. The pipe noise is incidental in comparison.

Cheap alternative mod is the airbox flapper, drilled airbox door, and open up the stock pipe.
believe me, I tried it all...

Now if you're looking for some farkles, I have a nice set of Pivot Pegz in the FM......

i would put the entire exhaust back to stock along with the EXUP valve if you have it as that improves low/mid range response, it will be quiet but still peppy and you wont have to repack the muffler. i have ran stock vs modded wrr's side by side and there is just not that much difference, imo. modded bikes have less mpg/more noise and unlike my neighbor with a harley, i want my neighbors to like me!

The whole stock vs aftermarket exhaust/ programmer has been debated multiples times in this thread as well as other sites. Each has its advantages.

Stock: quieter, heavier, less restrictive bottom end, more restrictive top end

Aftermarket: Louder( model depending), lighter, more(hair) restrictive bottom end((less power)), less restrictive top end

EXUP valve: In my opinion, based on what I have read and seen of vids in its action on the WR250R/X, its function is more for show and EPA noise standards than anything else. Extra weight.

AIS: Again, in my opinion, its post combustion, so only there for emissions reasoning and does nothing for running of bike. Extra weight.

Programmer: Stock maps are never optimal due to regulations they have to meet, for a street bike. Yes, Japanese engineers are very smart people, and make the best map they can to meet the needs and guidelines they have to have the bike fall into. BUT, especially when changing around the restrictive exhaust, changes are need to map.

So, for me, I wanted the lighter weight, and less restrictive top end( bike does not make a lot of power low anyway...so who cares about lower end). I used gearing changes to get a little more grunt on low end. I am also not worried about noise....I like to hear my bikes personally. I got rid of the EXUP and AIS....just weight to make the bike heavier than it needed to be.
And to boot, I got a used FMF Q4 can and a new programmer( private seller) for about $250 combined.

So, that was the right decision for me..others may vary. Get what works best for you.

I read somewhere the powerbomb is for more top end, and the megabomb is for more bottom, being that the wr is already weak at the bottom,I'd go with a megabomb.

I still have my stock header, so I really don't know. Personally, buying new, seems like a lot of money for maybe 0.7 HP it may add.

True true, I just don't like stock exhausts,I just need that aftermarket look, to each his own I guess right.


Where ya from in jerz, I'm right around the block from Pnc Arts Center. Ya know where that is?

Did the guy open up the airbox, remove flapper and all that? If so, there might be something to be said for having a more free flowing exhaust to balance that out. Of course that's assuming there is also a programmer installed to set this all up correctly. Going back to stock might be difficult if he ripped all that out.

FWIW - I did all the above + FMF + PowerBomb, and it's a noticibly more responsive, not a huge gain, but a bigger "smile factor". That being said, If I were to do it again, I'd have left it stock (Too much $, and a little too loud - but it's growing on me), but don't regret it by any means - and certainly not enough to go back to stock.

It sounds like the aftermarket mods just aren't worth it for some of us, especially if the low-end is compromised in any way. So far, I've put all my extra money into suspension work, as I'm beginning to ride it more on black-diamond narrow technical trails with jumps, square edged holes, etc...
Once you get the suspension dialed in (revalved and resprung) it handles the rough pretty well for a 300 lb bike. You definitely need that low end semi-grunt for lofting the front on the trails I ride - the conditions really don't lend themselves to high rpm's much. IMO, this bike just has enough low end to get the job done with a little weight shifting.

How high can you go? WRR ride height adjustment?

How high can you go on the WRR ride height adjustment? I got to looking at the ride height adjustment on my WRR awhile back and realized it was pretty far in compared to my buddies WRR and I'm taller than he is. I'm 6'4"/250, so the extra ride height is welcomed.

I have the shock off the bike sitting on my work bench and mine was set where the end of the shaft of the shock was dead even with the inside threads of the u-shaped shock mount on the inside. Obviously you need enough threads in that U shaped bolt that it won't come out or be stressed, but I would think you have some play there? Measuring the U-shaped shaft, there is about an 1" of threads in there. Measuring the threaded part of the shaft below the shock adjustment shows just under 1.5" total. So prior to this, I had about an 1" of shaft inside the U-shock mount. Could I go where I have about 1/2" of shaft inside the u-shock mount and about 1" exposed? That's probably about as high as I would feel comfortable with it and should leave plenty of the shaft inside the U-shock mount.

All I can find is posts about lowering the WR, and none of them spell out the procedure. This will be old hat very soon, but as a noob, and considering there is no mention of this "ride height adjustment" in the manual.. The PO of my bike said it was really easy, but I can't figure it out. I'd like the bike as tall as it'll go, then maybe ease it back. Where can I find how to do this? Google didn't get me anywhere.
