  1. 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?
  2. So I went to change my oil today and after trying to get the Allen key into the bolt head (and stripping a couple times) I gave up. The bolt on the top right of my oil filter cover is completely blocked by the header pipe of my exhaust! Luckily, I just changed the oil filter so it doesn't need it just yet. But what should I do? Do I have to get a new pipe or should I just try to bend it back? And if so, how do I bend it back? Please help!! Any suggestions greatly appreciated.

    So I just got done rebuilding my 2000 rm 250 bottom and top end. Its bored over 2.10mm to be a 265 (I believe). It has a Pro circuit header, FMF shorty silencer, and vforce 1 reeds. Its just barely broken in maybe an hour or two on it so far. It keeps fouling plugs and sounds a little rich. Its running a 160 Main (2 up from stock) and 48 Pilot (1 up from stock) with the needle clip on the stock setting. Should I change my needle clip position? Any help or tips would be greatly appreciated!
  4. Bought my 2015 EXC-F brand new 3 years ago, and haven't gotten to ride her as much as I'd like, but just got back from a 4 day trip in the Utah desert, and for the first time saw some of the shortcomings on my bike. Brand new I just got basic parts installed like a grab handle, skid plate, LED blinker bark busters, etc., but nothing to modify the way the bike performs. After doing some desert riding and some hill climbs for the first time, I think it would be nice to have a little better hold-up in the suspension, and better low-end torque/power delivery. I've changed the gearing over to 13/48, which seems fine for all around riding. My local riding areas are more woods and trails then open desert, but getting out in the desert and on some of the whoops (and riding my buddies '17 suzuki 250 MX'er) I realized how soft the suspension is. So there's two things I want to look at. First would be the suspension. I haven't even touched the clickers on it since I got the bike, as I'm 170 pounds and I'm told the bike is basically set up perfectly for me from the factory. That, and I had a bad experience with my old Yamaha where I never could get the suspension set up right and I'm kind of afraid of messing with it to a point where I'm lost and can't get back to the pretty good factory feel. The suspension seems set up really nice for the trails, but it would be great if it held up a little better in any jumps and whoops. Comparing to the MX bike I feel like I have to time my body position and throttle just right to get a smooth ride in the whoops, where the MX'er you can just power through. So, if I go a couple clicks in one direction or the other, can I keep the plushness in the woods and improve the performance on jumps and whoops, or do I need to start spending big $$ to get a noticable improvement in this department? On the power delivery, when I got the bike the dealer offered to put on an Akropovic pipe and re-map the bike to match. They said it would run a little cooler and bring on more power. Since I hadn't even ridden it yet, I figured I'd put some miles on it and decide later. After talking to the same dealer last week they said they can no longer adjust any mapping, but they could put on the pipe. I don't see what the point would be of bolting on a pipe if I can't adjust the mapping to take full advantage of it. I'd like to increase the low end torque, mostly. So, what options do I have to improve the power output and delivery? Thanks in advance! And because every post is better with pics... Here's one from Swingarm City in Utah
  5. I have a 2016 YZ250F. I ride/race MX. I'm looking to wake up the motor a bit and am looking at different exhausts. I haven't been able to track down a good pipe comparison for my bike - The best I've found is an MXA shootout for 2014. That shootout rated the Yoshimura the best but gave the pros and cons of each pipe. Is there a pipe shootout for my bike that I just can't find, or am I stuck with digging up individual reviews? If so, could somebody please send me links to some of the reviews? Thanks in advance.

    Recent purchase of xr650r

    Hello all, been here a long time ago when I had my 2003 xr650r. I had to sell that one a few years back and I have aquired a 2002 xr650r. My 2003 had a powerbomb header and fmf pipe. I am going to purchase a header and pipe for this 2002 but want to know your opinions about if I should go with FMF for the header and pipe? Any other suggestions? Best combo for uncorking? I plan to uncork it ASAP. So I will need a jet kit or maybe I can get away with spending less on a kit if someone knows the exact size jets I would need for full uncork and 6000' elevation? Also need a rear rack. I had a Baja designs rack before and I really liked it. Any others worth mentioning to me? Need buddy pegs. I ordered some before but dont remember brand or where I got them. They did the job and tucked up pretty nice. Anything there? I've seen some 650r's with the side panel that covers the air cleaner having holes in them. Are these homemade or does someplace sell them? My 2003 was never uncorked so what should I be expecting when doing that? I appreciate any and ALL info you guys can provide. Links welcome. I am in the USA Southwest NM. Thanks all. and GO BRP!!!

    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.
  9. Fo many years ive tolerated the sound of my kickstarter slapping against the top of my 2 stroke pipe. I can no longer take this. Here´s the issue explained. Somewhere along the life of my 300 xc-w I hit the pipe on some log or rock and ever since then the pipe and tip of kickstarter have been in slight contact. When I rev or ride the bike the point of the kickstarter makes the most annoying "ching" on the pipe. Please help me fix this. And no, im not going to buy a new pipe. (Mine is perfect as is)

    Dirty header FE501

    So, my header has gotten "stains" on it from riding in the rain. I'd really like to get it looking all shiny again.. Any pro tips?
  11. Wanting a more progressive torque curve, more traction, more low - mid range power. Not sure which ones of these pipes is better. I was told the FMF Fatty was the way to go, but reading up on the Gnarly makes me think perhaps its the gnarly? Anyone actually have experience with both?

    1991 DR350 Dirt model FMF Exhaust Q's

    So I recently purchased a 1991 DR350 Dirt model. It has several things on it that are upgraded. It also has several things that I am fixing so that I can ride it. One being the exhaust. So my question is (I know this is subject to opinion) which way to go with the FMF Megamax can? I know there are a lot of these out there on bikes that are in the same condition as mine without any discs or end cap. I have searched everywhere and have not found any used ones to be purchased that are within a decent price range. To me the can isn't worth spending $75 or more to get the missing parts when I could put a Powercore or something else on it and have the same or better performance. On the money saving side, has anyone put the Powercore cone on the end of this pipe and made it work? I have access to a machine shop and tools. The other option is if I were to make some discs and end caps (because the material and time is basically free using ends of metal that get scrapped anyway). It would be just as easy to make 50 discs as 10. Are there that many that would be interested in getting some to fix their FMF pipes. I'm not looking to make $ just trying to help out fellow riders. Just an idea. I know this option is a lot more work. On the other hand, a tight budget and having to work more to make more money also creates more work. Let me know what you think?

    What pipe should I get?

    I've been looking into getting a new pipe and/or silencer and I'm wondering which ones have the best all-around gains and are suitable for all types of riding. I'm currently running a pro circuit platinum pipe with a turbine core 2 silencer which is alright but the silencer is in pretty rough shape. Any suggestions? Any suggestions are welcome.

  16. I have an '08 200xc. I absolutely hate gnarly pipes. I like the KTM/FMF pipe (which is pretty much a fatty pipe I think) but now they are really hard to find. Some pipes say they will fit 06-10 or 03-04 or 04-05 or 06-07 or 00- 06 or 00-05 or 04-15... you get the idea. Whats the real deal here? Ideally I just want a fatty pipe on this bike or just something that isn't focused on low end torque.
  17. I feel like ripping my hair out! I bought a 2005 cr125 years ago, brand new. From day one it was a fouled. Eventually I had it tuned kind of good. A couple of years ago someone stole my bike. Obviously I recovered it. My crank bearings were shot. So I split the cases and changed them and both seals. After assembling the bike it smoked and bogged like crazy. I thought I may have fudged up the right crank seal when I installed it...nope changed it and still smoked and bogged and fouled. It sat up for about a year and I just broke it out again. It doesn't smoke as bad. If I idle for about 10 seconds it'll blubber and shoot out smoke before fouling a plug. The strange part it that it rides pretty good on the pipe, but out of the blue with blubber and eventually die. Now After cleaning the spark plug and kicking it, it'll turn over for a sec and die. The spark looks weak so I check it with a new plug and it looks good (so I'm assuming it's not the ignition system) anyone else have this problem? I'm beginning to think this bike is a money pit...but on the same hand I feel like it's something small causing all of this. Oh and also it's dripping that black crap from the tailpipe and plugs are always wet. I went down a size on the pilot...didnt help.

    What brand exhaust is this?

    I purchased this for my 2005 Honda CRF450X and need to know what brand or mfg it is. It's a full system with carbon fiber end cap, spark arrestor and long header. It's way too loud and I need to ID who makes it so I can see about getting a quiet core insert.
  19. My 2011 YZ250 is undergoing a full engine and chassis rebuild and I have decided to go with a 300 kit (the bike needs a new cylinder anyway so this is a good time to do it). The current YZ250 power curve/delivery is good so i'm not aiming to create a torque monster that doesn't rev, just looking to add more power throughout the current range. I primarily ride MX, intermediate level. My questions for those run an Athena 300 kit are below: Has it been reliable? Is there in increase in bottom end/crank problems? What pipe/jetting do you run/recommend (for MX, 0-1500ft altitude)? Anything I need to watch out for during install (I've heard Athena circlips are bad)? Did you have custom porting done and if so who do you recommend for that? What octane of fuel do you run? Thanks in advance!
