  1. Hey TT'ers, hope you don't mind me posting this! Figured some might appreciate! @FMFRacing73
  2. RANCHO DOMINGUEZ, CA – March 8, 2017 – (Motor Sports Newswire) – Rocky Mountain ATV/MC stopped by the FMF Powerhouse last week to sit down to discuss some history of just what makes the FMF Brand tick. See what fire, metal and fumes have created over the last 45 years and let FMF’s own Don Emler Jr give inside scoop on what it means to be 100% Made In America. “Rocky Mountain ATV/MC brings you an Inside Look at the Flying Machine Factory. FMF was there in the days when the singleshock and watercooled engines were huge innovations and we’re glad to be here now for the aluminum chassis and electronic fuel injection. Our goal will never change – take the most advanced machinery to its limit by building the world’s best performing exhausts. And it’s a fact, we build every exhaust by hand from start to finish right here in the U.S. The biggest reward for us is knowing we’re helping our customers get the most out of their riding experience. We still ride every chance we get so we never forget why we got into this business in the first place.” Follow us: Instagram: @FMF73 Facebook: https://www.facebook.com/FMFRacing/ YouTube: http://youtube.com/user/FMFRacing1973 Follow Rocky Mountain ATV/MC: Instagram: @RMATVMC Facebook: https://www.facebook.com/rmatvmc YouTube: https://twitter.com/RMatvmc About FMF Racing Established in 1973, FMF Racing is one of the most dominant and influential brands in the world of Off-Road Motocross Racing.

  4. This video shows how to install the spark arrester on the FMF Powercore 4. There is no known video or instructions that i could find for this exhaust model. Very simple install. I couldn't notice any real sound difference between the spark arrester in or out. If you like my video please subscribe, like or share this video. for comments or questions please leave below. Make sure you check out my channel. Thanks for watching.
  5. I have a 2012 YZ250 with FMF Fatty and Shorty combo right now but I’m not National Forest friendly here in NC. I mainly want to hear from those that have direct experience or knowledge with the FMF Fatty and PC 296 spark arrestor and how it plugs and plays. But also any arguments against it and recommendations are also welcomed! #yz250
  6. Has a Wiseco top end, v force 3 reeds, 11oz Steahly fly wheel weight, FMF Gnarly exhaust, and a FMF powercore 2 silencer. This is one of the best dirt bikes I've ever owned and ridden. It's a bullet proof motor and it's never left me stranded or gave me any problems. I'm planning on getting a Lectron carburator or a Smartcarb carburetor because I hear they are like fuel injection for a 2 stroke.
  7. Hello tt members I'm not new but I'm new to posting had account for I would say I'm well over 2 years anyways I have a 2011 rmz450 and looking to and alil more hp or speed to it so I currently have a full fmf 4.1 to mega bomb rct pipe on it and trust me sounds great so my first thing I want to do to engine is hot cams stage 2 now I here it adds more mid-top end power I want to know have anybody had this done to thier bike or similar and want to know does it make a big noticeable difference and next I want to add a pc5 and also wanted to know if this make a good difference I know alot of people say Suzuki s have like the slowest 450's but I see that it has potential to be faster than what it is thank you so much all the advice would be great
  8. Can anyone explain to me why the mid-pipe on certain XR600R/XR650L exhausts gets substantially bigger before attaching to the muffler? In most cases it is actually the same size as the muffler where it attaches. The XR's only mufflers are a great example of this and so is my White Brothers E series muffler. On the other hand you have the more traditional mid-pipe shape from companies like FMF for the same XR600R. The midpipe is relatively the same size from the header to the muffler connection. Even high performance street bikes use this approach so why is it different with the big single? I've been looking at replacing my White Brothers muffler lately because it doesn't have the discs nor the backing plate to make it USFS approved. I've been back and forth between the FMF Powercore 4 and the xr's only mufflers. I was wondering if the odd mid-pipe shape helps the XR's only mufflers flow better. From what I've read the XR's only mufflers are stupid loud and that would warrant a quiet insert for me and thus choking the high flow muffler, right? Also, for anyone wondering- the White Brothers header that was installed on my XR600R is VERY CLOSE to the same dimensions as an XR's only header at both the cylinder and mid-pipe connection.

    3x3 Drz400sm lost grunt

    I am stumped on what to do and looking for guidance. i have a 2018 Drz400sm. put it through the first service then went through with the 3x3 mod with JD jet and full FMF pipes. followed everything the jet kit said and tuned for sea level with blue needle in 3rd position 160 main and 25 pilot and fuel screw 2 1/2 turns out. Took the bike for a spin and it ran like crap. Idle is fine . But the bike just has no power anywhere and feels like a 50cc machine. Top speed was 95kmph on the road. So following this a took the carb apart and tried more jetting combos thinking it was just running lean. No success. Still slow with no response. I put the bike back to complete stock jets and exhaust and taped over the 3x3 hole to replicate the snorkel back in. And even then it ran the exact same no power and weak response. So currently the bike is sitting back at full fmf exhaust , blue needle in 4th position, 160 main 25 pilot and 2 1/2 turns out with 3x3 airbox standard air filter. All to which it runs slow like the throttle doesn't work but every now and then it surges in power for a second and dies away. i looked into the TPS ( throttle control sensor) and it is running the correct resistance of 5 at closed throttle and 3.9 open. What could be the problem? help would be much appreciated.

    250SX Exhaust

    I have a 2017 250SX and was wondering what the best exhaust is for motocross riding. Is FMF 2.1 or a Pro Circuit system more suited to track only riding? Any help is appreciated. Thanks guys!

    2001 YZ125 Exhaust Setting?

    I am planning to buy a FMF Fatty for my 2001 YZ125. I heard that once you install it, you need to rejet your carb. What jet should I change and what size? Thanks.

  15. I've tried searching and didn't seem to come up with any answers. I'm wondering if a Pro Circuit silencer will mate to a FMF Fatty head pipe? I'm considering the Pro Circuit Nature Friendly silencer. Like everyone I'm on a budget. Problem is I have a 93 Rm250 and I need a spark arrestor. I have a Gold series head pipe and Power Core silencer and they don't seem to make spark arrestor kit for this. I didnt come up with any results when I searched for an FMF silencer that would work on their website. What are others doing for Spark Arrestors? I had a KX 250 in the past with the opposite setup where I ran a Pro Circuit head pipe and a FMF silencer. Thanks in advance
  16. I have just bought a new FMF Gnarly for my 2012 KTM 200 XC-W, it works great but i want to use it to its full potential to get my moneys worth. So i need some advice on jetting my carb for the Gnarly pipe. Any ideas on jetting for my bike? Thanks

    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

    Bought a gem of a Dr350

    Hello TT! First post on this forum, only because someone has already answered every single question I've had in the past year. Seriously you guys F'n rock! Very anxious for the snow to melt so I figured why not share my Dr with the world in the meantime. I wanted to pick up a thumper last August to have a dualsport to take to class and mess around trails when I was up at school. Nothing nice, just something dependable with mostly original hardware for under 2k (broke college kid budget) did my research, it had to be a Dr. So I trekked from southern NH up to Maine to look at a '99 Dr350se with 14K on the OD... I know 14K is a lot, but the pictures looked great. The guy selling it, who was only the 2nd owner, said it had just about no rust and he had only done 1000 mi on her in the 2 years he had it (which was actually true I have the title) The bike looked perfect when I got there other than that blowby on the tail. But for a '99 with high miles I figured she would at least need rings and gaskets soon. Wicked cool guy no BS, he never touched a thing on the bike besides battery and registration stickers, the thing just ran. He insisted I take it for a test ride before I even consider making an offer so took a little cruise up the dirt road and left my girlfriend to lay down a little pre-negotiation charm on him the wife. By the time I left wifey was bringing me to the shed to grab all the free spare tires and wheels the four of us could carry, and they were all in usable condition. Next hands me 3 soft binders, one was a general maintenance manual, one a model year specific manual, and one stacked full of documents, receipts, title and handwritten parts lists ended up taking everything home for $1200, $200 lower than the asking price just because he thought I was a good guy. (Total wheels and tires I got for free was a complete front and rear set each with 50/50 on/off tires mounted, as well as 2 rear on/off tires and 1 spare front mx tire) But wait there's more... Of course I'm dying to see what receipts are there so lets have a look... Everything with a receipt was dated from 2008-2013 (could be worse right?) we've got: Both sprockets (stock gearing) Chain Discs & pads Fork boots Front fork seals Clutch Clutch cable Now I start getting into the nitty gritty... no receipts or dates but after doing a little sleuthing: DynoJet stage 2 or 3 kit (found the 'in box' installation instructions, plus the jet sizes are scribbled down on that paper i mentioned) 1 1/2" exhaust mod (found email printouts so I go check the bike, sure enough 1 1/2") and for the Holy Grail... Yes that's right ALL of the emails back and forth regarding shipment for the 440 big bore and sleeve May I add, when that guy said no rust he wasn't joking. There's a flake or two on the exhaust but everywhere else is paint. Every nut bolt and connector on the Dr440 is completely stock, right down to the alien antenna mirrors. The bike obviously couldn't have been ridden that hard, I broke those mirrors off that first week... Airbox has the big ol holes of course. It has a K&N reusable air filter pretty sure that is not stock correct? It had motard tires when i first got it (in that pic by the river) but I am taking this spring to gear her a little more for more dirt. I just wrestled a brand new DOT track tire onto the main rim and I have that mx tire mounted on a spare rim sitting on deck. It'd be awesome to get some input from you guys, maybe do's and don'ts on modifications I can make from here? Also let me know what you think of my plans, I'm open to all (most) input. Right now my grocery list is as follows: -1 in the front (currently sits at 15/44) FMF pipe (what's the best option for Dr? is there a full FMF system for a '99 Dr or just slip ons?) DynoJet Stage 3 (if I don't have it already, how would I go about checking the jet size?) RaceTech rear shock spring ( 7.2 kg/mm or 7.6 kg/mm constant rate? suggestions?) POSSIBLY swap for RM fork or just revalve? (is it still worth doing rear and not front?) Thanks a bunch guys, I'm dying to hearing what you think

    How can I make my bike faster?

    I've heard if you put VForce Reeds, properly jet your carb and clean the carb, change the exhaust pipe, clean the airbox and put a new air filter, and properly fix the shocks to match your weight, you can gain a ton of power?
  20. I'm reading up on these.. Anybody have one?Can you compare it to a Gnarly or a Fatty for a YZ250 or 250X?
  21. I'd like to step up to the Powerbomb header on my XR/L but have ruined/burned holes in a few pairs of riding pants on the Powerbomb on my last bike (KLX250S). I am pleased with the Q4 on the XR/L and believe there might be a little more to be had with the FMF header, so I'd love to hear and see pics if possible of what kind of shielding you all have used or created for the Powerbomb on this bike. Thanks in advance! TC

    FMF or Pro Circuit?

    Hey what's up guys! I am planning to change the exhaust system on my 2001 Yamaha YZ125. Now here's my question. Should I put a FMF Fatty Pipe with a Turbine Core 2? The total is $350. It sounds insane with the combo. But if I purchase the Pro Circuit Platinum Pipe with the R-304 Shorty, I will gain horsepower. But it will sound like trash. I trail ride and I like noise. What combo should I buy? Thanks.
  23. I'm sure this topic has been abused but...I have read that the FMF FACTORY 4.1 RCT Slip On improves the low and mid performance. Does it rob the top end at all to do this? Has anyone that has installed experienced any loss in their top end? Does it still pull as long in 5th?
