  1. Hi Guys I was on XR's Only website last night, and see that they have updated the looks of the muffler for their exhaust system. Looks much better than the old one. http://www.xrsonly.com/xrs-only-exhaust-pipe-honda-xr400r-stainless-steel-cone-tip http://www.xrsonly.com/xrs-only-exhaust-header-honda-xr400r So I'm just wondering if anyone has experience with their full system? It will be for a 440 setup. They say the header is larger, but also say the muffler can connect to stock headers?? Sooooo, Power?....Quality?...Noisy or not? Thanks
  2. Hi guys! I am very new to thumper talk so i am sorry if i am asking this in the wrong place! I ride a 2007 XR250 motard and it has a VitalSpirit exhaust system (including the header pipes) I found a vid in youtube of a bike with a similar exhaust Just wondering if some one has used a similar one, the pros and cons of it because i was thinking of replacing it with something like a delta barrel 4 Thanks in advance!

    Yzf 250 exhaust

    Does anyone know if a 2010-2013 yzf 250 exhaust will fit my 2009 yzf 250?
  4. I bought this bike in January and have been going though some maintenance and upgrades. When I took the exhaust off to repack the muffler I noticed that the header only goes into the slip joint connection by the kick lever about 1/2". You can see in the picture that at some point this header was engaged at least another 1". The pipe does not appear to be bent and the silencer bolts line up perfect with the frame. The header was also hitting on the back corner of the cylinder and at the lower radiator hose clamp. But I was able to adjust to barely clear them now. It's definitely a Yamaha factory header with the heat shield tabs cut off. Thinking the previous owner swapped a header from a different year... any thoughts?

    Loose fitting exhaust 08 crf250r

    Howdy. I have an 08 crf250r with yoshimura rs 3 titanium dual pipes and they're fitting really weird compared to my dad's Kx 250f. I recently bought the bike with the exhaust installed, but the previous owners were about as far from mechanics as anyone can really get. Coming out of the head, the exhaust has a little insert that mounts with a plate and fits inside the header pipe. The little insert wobbles around and I am pretty sure they have the wrong parts on it. Could anyone tell me if that's supposed to be like that or where to get a new retainer plate (the one that mounts to the studs on the head) and the insert? Thanks Hayden
  6. I have researched the threads on this exhaust pipe topic but still unclear on the differences on the exhaust pipe mount at the rear footpegs on an S versus an E model, (I can’t find a good photo of this). I have 2 scenarios/questions. I’ve read that the E front head pipe has a larger outlet diameter (41mm I believe) than the S headpipe does. 1. I want to use a E front headpipe on my 2001 S model using my OEM stock S muffler, how do you connect the two, have a muffler shop expand the stock pipe or fool around with using adapters? Or can it be done at all without being a PIA? 2. Let’s assume that the E headpipe is successfully connected to the stock S muffler and 2 years later I decide to add an aftermarket muffler. Which way would be the easiest : A. Order a muffler that fits the S which will require connecting the two pipes together (again), but the footpeg mount will be the same. or B. Order a muffler for the E model, the 2 pipes (should) simply slip together, but the footpeg mount will be different and needs modified (somehow). I just want the easiest way, this rear footpeg mount is where I’m stuck on a decision…… I want to get the new headpipe soon, maybe a new muffler next year. Thanks for your inputs.
  7. Hey everyone, I’m new to my drz 400 and have now spent a couple hundred dollars getting it to where I want it to be. Now I’m at the point where the only thing I need is a exhaust with a good flow, and was wondering if it would be possible to fabricate my own header and pipe , and simply attach the stock muffler on the end ? Thanks!
  8. I know this has been talked about somewhat but I'm hoping you can narrow this down for me. I am getting too much spooge coming out of my exhaust. A couple drops here and there ok, but I am getting quite a few drops, too the point where my rear hub is getting speckled and my swing arm is fairly dirty. Other racers I'm around don't seem to have this problem. I have a 2009 ktm 105 sx. The bottom end was replaced recently, new head pipe o rings. I have ran both 32:1 and 40:1 premix ratios with the recommended motorex oil (I know you don't jet by changing ratios, I'm just experimenting). The oil has just been changed and its clean. I run the manuals recommended jetting specs for my temp and elevation (if the google maps elevation markers are accurate). Air screw is two turns out. I run the engine hard around the local sand track. I have also noticed that although I have changed the o rings on the head pipe, oil still leaks there too. At least one head pipe spring is new, maybe both of them. Silencer has been pulled apart and the packing really didn't look that bad so I put it back together as is. The air filter is cleaned regular. I use the highest octane pump gas as I can get and stay away from ethanol. I have cleaned the carb recently, and made a decent attempt at setting the float. I have been told that the ktm recommended jetting specs are slightly rich. But how rich are we talking? I am leaning towards just changing the clip to a higher position on the needle but not sure if there is a better way? (clip is at the second position now). I am trying to jet for a race this weekend that is in a higher elevation than I am currently at...so I can't really test until I get there and time will be limited. So all I can do is follow the manuals recommended specs. on the chart and try to compensate knowing the current performance. The bike seems to run well overall. It idles well. Seems to pull well through every throttle range. Could sometimes be slightly more crisp at a quarter throttle...but hey this is a small bore bike...it not going to be like a four stroke. I would normally say that the bike is probably too rich, but I am at the recommended jetting specs, I'm not fouling plugs, and the bike runs well. I am hesitant to go past what the manual recommends for jetting as I am worried I may not recognize the symptoms of a lean bike soon enough, due to my relative inexperience with 2 strokes. (yes I know its supposed to sound like a marble in a tin can and lose power but I have never experienced it myself). I don't want to bugger up a good thing. Thanks for the help guys! I am probably just thinking about this too much

    EMGO universal muffler/exhaust?

    Thinking about picking up one of the EMGO universal mufflers for my 2001 XRL. Has anyone ever purchased one of these for their XRL? It's about 300 (Canadian) dollars cheaper than the FMF (my other option, currently), and sounds great according to the ONE youtube video I found (see link). More than anything I'm worried about the fit (into the header, out into the rear of the subframe) - if anyone has experience please let me know. Additionally, I am thinking about jetting (of course), but this is something I can work out post purchase... `

    new 2017 crf450x glowing exhaust

    Hello all. I just wanted to get some other crf450x owner input on something my brother noticed on my new bike. So this is on a newly purchased 2017 crf450x with about 4 miles on it currently. while riding around with my brother in my inlaws yard he pointed out that the head pipe was starting to glow red. I'm wondering if this is because the bike is new and is a bit hotter due to breaking in or if there is possibly a different issue going on with this new bike. Most of what i read suggests a lean issue presenting it self with the carb. i just installed a trail tech vapor kit on the bike but i doubt that would influence anything. Any help would be greatly appreciated. hopefully this wont abort our first trip out to go ride it this weekend.

    Silencer science

    I have a 2005 yz144 with a pro-circuit pipe and pc r304 shorty silence. I’ve always thought that a short silencer improves low end power and longer silencers improve top end performance. Would the factory yz125 silencer perform the same as pro-circuit 304 silencer? Any thought would be appreciated. Would Jetting need changed?

    LEXX MXE exhaust uh oh

    Hello all and welcome to my first post. I've just acquired a DR-Z 400 E and without realising the difference between a Z400 (quad bike) and my humble DR-Z 400...I went and ordered a new Lexx MXE exhaust ...For a Z400 SO, nothing I can do as it's on it's way and I live all the way south in South Africa so I need to make it fit and the DR-Z 400 Lexx MXE from Australia is a whopping AUD400 Does anyone have any pearl necklaces of wisdom for me?? Anyone know the pipe difference (as I find comfort in the fact that the actual exhaust is the same)? Look forward to hearing from anyone out there. Cheers NotBlueSteel Cape Town
  13. The graphics on my exhaust side number plate keep melting off where the header and the muffler meet… I tried moving the heat shield that was included in the plastics over a little bit but nothing seems to work does anyone have any suggestions?

    1980 DR 400

    I've just bought a 1980 DR 400, I need an exhaust for it, I have the header pipe for it and the muffler but I can't find either the soup can middle section or a "S" pipe to fit it together. Does any one have any suggestions? I'm willing to put a new exhaust on it if I could find one. I used to have a 1977 DR370 years ago it was tractor like bike, but I bought a Hooker header for it back then and can't find anything like that now. Any help will most appreciated.

  16. Hey all, Just installed my yoshimura rs2 full system and have been having alot of backfire on deceleration and engine breaking. The bike has a 3*3 mod and jd jetting. The kit says to use the 165 vs the 155 if you have full exhaust. Could the issue be having the 155 installed and not the 165? Or could it be a header leak. It looks like the flange on one side is just barely not flush but it will not tighten anymore than it already is. If you think it is a header leak what is an easy way to test that? Im thinking its the jetting, but thats just my amateur opinion. Any thougts?

    Another big bore question

    So Ive decided its time to pull apart my favorite machine and freshen it up, and I'm looking to make some improvements in the process. I already have a 3x3 mod and a JD jet kit done and it seemed to have changed the world. The stock bike just plain sucked and now its a lot better. I never expect 450 race bike power here but I know there is a little more and I'm wondering if the juice is worth the squeeze. I already plan to add a header and exhaust, an FCR39 carb and stage 1 hotcams. After some research it really seems like those places are where the gains actually come from, so would it be worth it to throw a 434 big bore kit at this bike or just stick with what I already mentioned and a new stock bore top end??? Also my rides are often solo and pretty isolated,how much of a reliability headache can I expect with these mods?

    YZ125 Missing Exhaust Bridge

    I bought a 2004 YZ125 a couple years ago and the bike has run like a charm. Anyways a couple weeks ago I was riding and the powervalves snapped and hit the piston and I lost the top end. Anyways I ordered a new top end and replacement powervalves but as I was inspecting the cylinder I noticed something. The cylinder bore survived just fine and just needs a deglazing but I noticed that the entire exhaust bridge is missing. The cylinder has been sleeved with an LA sleeve and the exhaust bridge on the inner bore of the sleeve is perfect but the original aluminum exhaust bridge in the cylinder behind the sleeve is completely gone. Is it ok to throw the new powervalves and top end in or am I looking at needing a new cylinder? Also thinking about it now, if the exhaust bridge had just come completely out as I was riding would I have lost it in the pipe? There isn't any evidence of shavings or pieces of the bridge anywhere in the exhaust port or the pipe. Also, the piston has no damage other than from the powervalves hitting it. It makes me think the exhaust bridge has been missing since before I bought the bike

    Looking for a cheap TTR90 Exhaust

    Hi Everyone, I just picked up a 2000 TTR90 for my son. the previous owner had the exhaust fall off while riding and a guess left it in the desert. Anyway I want to pick one up, cheap. I'm not looking for extra power or anything. Ebay has a ton that say they fit, but I don't see how they fit the support bracket, and the exhaust pipe is 26mm, but these all seem to only go down to 38mm. here are some links so you can see what I'm talking about. If you know a good link for one please let me know. https://www.ebay.com/itm/Universal-38-51mm-Motorcycle-Carbon-Fiber-Exhaust-Muffler-w-Removable-Silencer/332167907200?fits=Year%3A2000|Model%3ATTR90&hash=item4d56c00780:g:WSQAAOSwzgBY23oo&vxp=mtr https://www.ebay.com/itm/28mm-Exhaust-Muffler-For-90cc-110cc-125cc-Dirt-Pit-Bike-TTR-CRF50-SSR-Thumpstar/321988125687?hash=item4af7fce3f7:m:mtBWjDVUEnYxJPki7bidl3Q&vxp=mtr https://www.ebay.com/itm/Universal-38-51mm-Motorcycle-Carbon-Fiber-Exhaust-Muffler-w-Removable-Silencer/232615617126?fits=Year%3A2000|Model%3ATTR90&hash=item3628f8a266:g:WSQAAOSwzgBY23oo&vxp=mtr
  21. I have a 2008 CRF150R Expert and am trying to find a way to get more power on straights, any ideas for modifications?
  22. So I just bought a 2006 YZ250F and it has an older Dr D Carbon Fiber exhaust and I noticed that it did not have a spark arrestor which is needed to ride trials legally here in Oregon. So I did some research and I saw that you can't put one in there because it will damage the pipe. Does anyone know why this could damage it and is it possible to even put one in there? Thanks, Talon

    Dirt bike Exhaust

    Hi I'm quite new to dirt biking basically I haven't really payed attention to the bottom of the exhaust but there is a hole on the bottom at the end of the silencer is this normal ? Would appreciate any replies thanks.

    Head pipe cracked Help!

    I have a 2005 CRF450R, It cuts out when you get on the throttle when taking off from a dead stop it cuts out near the bottom end. After some research one of the suggestions was to check for an exhaust leak. I replaced the gasket between the head pipe and the silencer and still no fix. Then I noticed there is about a 1" crack right at the 1st bend coming out of the barrel. I don't want to spend the $500 on aftermarket exhaust so am trying to find someone to weld it. Nobody around here welds titanium. Does anyone have any ideas or suggestions? I have found some full aftermarket exhaust for 270 for a 450X would this work on a 450Rif i re-jet? I have seen that in the 2005 the exhaust is interchangeable between X and R, Could I use a factory 450X head pipe with the 450R silencer? Thanks folks.
