noise, no tach, etc

Well, just reading about how some folks don't think this bike needs a tach. Well I've been getting used to the bike now and so I've been cranking it a bit harder and revving it a bit higher. But I've never hit the rev limiter yet. I'd love to know when it's close to I can shift at highest revs.

As it is, I have basically revved it until it sounds like 'that's enough' and shifted etc. True, that revving it this way is certainly good enough, just going by feel. And when I get used to it I'll likely hit the limiter sometimes and get the feel of how high a revs that is.

But, sure would be nice to have a tach...

Not to mention a gear indicator would be really sweet...

Now about the stock muffler sound. It's freaking loud, no idea why some people can say 'it purrs' 'really quiet' etc. I checked to see if the spark arrestor is still in and I think it is. Dunno, do you have to take the end off to see, or the fact that the smaller pipe is visible indicates it's in there?

I wish it was quiet, don't like loud bikes. About the intake sound - it's loud! Stock airbox, flapper etc is all there but it's quite loud. I should mention that my ExUp servo is removed and Eliminator plugged in, but that's it as far as changing stock stuff.

I'm not an earplug guy, except on fast road bikes and I don't ride on the highway much, but I may have to wear earplugs on this bike.

I'm amazed at the takeoff when cranking the bitch hard through the gears though, the power IS up in the higher revs. I also have no idea why people spend fortunes on exotic Power Commanders and pipes etc because the stock bike rocks.

Ok I might as well say this too - removing all the air pollution control stuff is just crazy. I mean, the earth is polluted, why do people feel they are exempt from helping reduce pollution? You know what's really crazy? People are gonna hate me for even mentioning this.

Hate you?
No.
Disagree?
Yes.

Power is already dropping off by the time you rev the engine high enough to hit the rev limiter, so why bother making a habit out of that?

If you think the exhaust muffler and intake noise are loud, I find it hard to believe those areas of the bike are stock.

The reason why I used a DynoJet Power Commander and an FMF Power Programmer on my WR-250R and WR-250X is because the throttle response was much better.

Let's take it a step further by permanently parking all of our bikes, cars, and trucks, horse-and-carriage or walk everywhere we need to go, dismantle all Interstate highways, close down all oil wells and gas stations, cut our own firewood for winter heat, go without air conditioning due to no power stations operating, and start clearing 90% of the wooded land in order to grow our own crops and graze our own animals within our own communities and not have to bother with traveling from one town to another on a daily basis.

You can access the factory tach via DIAG Mode just to at least enable you to see "where you're at" in regards to the rev limiter. In any case, it will cause no harm to this tough little motor to just hold it flat at any time and hit it.

There are plenty of sites via a google search, including you tube videos, to show you how to access DIAG Mode. ( Including a very good thread on this site to walk you thru the access of D/M ).

Lastly in regards to removing "all the polution gear" on this bike with various mods, well all i can say is that aside from the Cat Convertor in the rear muffler, the other items really have no effect as far as carbon exhaust emmissions go......

Now if you really want to make a statement about "bikers" doing their bit on emmissions, then what really shits me is all those "tree huggers" on pissy little "made in china" scooters.... They happily hold up all the traffic flow, all the while thinking how they are saving the dolphins, when in reality the 3rd world manufacturing process of these things in china creates way more polution than the life span of most big V8's. LOL.

Cheers.

I've hit the rev limiter about a ca-gillion times. Just do it. You won't hurt anything. Promise.

That's the the rev "LIMITER" is there for. So you don't damage anything.

As for the loudness - do you have a used bike? Did previous owner remove spark arrester or somehow modify the stock canister?
That's the only way I can think the stock system could be considered loud.

Here's the thing - Having to look down to view a tachometer means you take your eyes off the road/trail. Because of the seating position you REALLY need to look DOWN. This isn't a sport bike where you can almost see the instruments with peripheral vision because the lean forward seating position.

Constantly looking down at a tach would more than likely be a dangerous distraction on public roads.

Your engine is 1/4 or an R1 engine. It's made to withstand some pretty insane abuse. Plenty of people here have put in serious miles and had no issues.

Don't baby the bike. Ride it. Ride it like you stole it. Find the limits of the rev range a few times and you'll be just fine. In second and third gear you'll hit the rev limiter pretty quickly. I honestly can't believe you've never hit it in first gear. That comes in a blink of the eye.

Put a Powercore 4 and fmf fuel programmer on it then tell me about how it makes enough power stock and how the stock exhaust is loud. I see people with new bikes all the time that want to know what mods to ad first. I tell them that I wouldn't ever ride a WR without a pipe and programmer.

I don't usually rev it too high in 1st because that gear is so low, and 2nd gear is where it really takes off, but I must have come close to the limiter in 2nd. I'll see what I can do about hitting it in 2nd :)

And I can dig what you say about looking down at a tach being dangerous. It's likely the reason they didn't allow the tach feature.

I'm going to open the end of my muffler and see what's in there. I'm going to open the airbox door too and take a look in there.

I'm not about to go back to horse and buggy, but I do own a bit of forest and I do harvest firewood to heat my house and save the oil etc. I think I'll go out and hug a few trees right now.   

Don't want to remove the emission stuff to reduce pollution, but burn wood to save on oil??????? Love it!!!!

Ok it seems my muffler is welded, no way to remove any spark arrestor, so I guess my muffler does have one. In my opinion that's the way it should be. I'll have to live with the noise. Since it's a Japan market bike and muffler, I guess it's a bit louder than the exports. Less restrictive too is my guess, since my pipe doesn't seem to be narrower at any place in the run.

I guess you don't realize that wood stoves can be non-polluting. Our stove has a catalytic burner and burns with no smoke.

How about I DON'T put in a Powercore 4 and FMF Programmer, but tell you that it makes enough power stock.

It makes enough power stock. There, I said it.

Spark arrestor is right at very tip of exhaust canister, if you have a stock pipe, as it comes from Yamaha, it's very easily removable.

Can you post pictures of your exhaust pipe. Side and end pics?

It's 3 bolts to get spark arrester out of stock exhaust.


Item #14 in fiche.

No visible smoke from a catalytic wood burning stove must mean no greenhouse gas emissions are generated. My bad. No smoke comes out the tailpipe of my fully modded bike so it must be non polluting as well.

I could, but there's not much to see. It's welded, no removable part anywhere. Like I said, this is a Japan bike so the muffler must be different here. Might also explain why it's louder than stock pipes in other places.

It looks stock, I mean it's painted black and looks factory.

Yikes....that sure isn't like "ours".

Are you on an F model? or an R model?      

Your side panel and tail piece looks different too.

The side panels are custom as well as the fender eliminator kit and the graphics, part of a special from one dealer here. However, I think the muffler is stock on all WR250Rs here. Yes my bike is an R. The muffler is minus the heat shield due to the special side panels.

The supplied picture of that stock rear muffler shows to be the same as per the "EURO" spec WRR/X.

Motokid are you 100% sure that the "USA" spec bike does actually have the bolt off muffler end cap, as in have you personally seen that set up on the stock bike ? I'm not doupting what you are saying mate - just more so curious to see if there really are such "major" differences in the 2 spec's.

I know that it shows a diagram in my factory Yamaha Workshop Manual of the bolt off end cap to access the S/A, but my EURO spec has the same "sealed" end cap as per the OP's pic.

Could be a case of just having the picture of 1 "standard" model spec in the factory manual - but there are obvious small variations depending on specific markets.

Another case where it seems that this variation may be possible is for the front sprocket - as in members on here say that there is a thrust washer between the lock nut & sprocket, and my manual shows this as well - but for my bike from new there was no seperate washer ? ( But it did seem to have a thick "washer like" spacer built into the sprocket ). I know in another recent thread about chains/sprockets, that YZEtc did supply the Yamaha part number for this sprocket thrust washer.

So i take it that the OP's bike is a EURO spec bike with O2 sensor ?

Cheers guys.

Yep - mine for sure had the bolt on "cone" and removable spark arrester.

I removed mine to see what it sounded like and hated it immediately.

^ Ok no worries - must definately be a different rear muffler for the EURO spec then.....

I know that for me the stock unit was very, very restricted + i could fart louder, lol.....

Anyway, it went in the "bin" with-in 200 klm's for a free-flow GYTR.

Cheers.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

^^  Hey brother if you really truely do believe that it's "freaking loud", then i'd most likely suspect that you have SUPERDUPER Hearing !  LOL.

......BUT, Seriously it's a pretty pathetic sounding "chook chaser" with the stock rear pipe IMO.

Anyway have you finally "found" that rev limiter yet mate ? ( Best found & most fun in 3rd gear,    ).

Cheers.

just to chime in... yes that is the stock pipe for the Euro model.

and no it's not loud. According to official measurements its 88 dB at 5000 rpm

So it seems Euro spec muffler shares the welded up muffler end with my Japan spec. However, no O2 sensor is on my bike. These differences are likely dictated by regulations in different countries. I have no idea why a spark arrestor should be removable.

And it's not real quiet either like I said. But noise limits here in Japan are likely higher than in the US. I may find other differences in this Japan spec bike, will note the front sprocket/spacer when I get around to changing that. I'm curious now though what size sprockets I have front and back.

Haven't been out to find the rev limiter yet but hope to soon. I'm also going to do a top speed run.

I believe the spark arrestor is required by the US Forest Service and is probably a hold over from the old 2T days. Might explain why we have the pipe that we do in the States.

Yep, I'm beginning to think the US model has the spark arrestor, and maybe the Japanese model does not.

Considering how loud my muffler is, you might be right. It's definitely different internally.
