FMF FATTY VS SHEARER PIPES 421 SERVAL BANSHEE 2018
HTML-код
- Опубликовано: 29 июл 2018
- Testing out the FMF Fatty pipes. They are a lot more ridable in the trails with a huge improvement in midrange performance. Perform very well on the ported serval. I'll probably throw the Shearers back on to do another seat of the pants comparison. I think for more wide open riding less tighter areas the Shearer are better. All personal preference of course.
Thanks for watching please comment on what pipe setup you are running and why.

I never get tired of hearing a twin two stroke... I could set that sound to my alarm clock :)
the fatties would kick ass in the desert
Then you wouldn’t wake up tho
Nice video, thanks
I ran fmf fattys before on my stock cylinder, a great pipe that is underrated in my opinion, best of all is that you can find a used set for cheap! I now have a 4mm cub on 39mm pwks, and shearers, I dune and drag, so that setup is perfect. If I ever ran a dune ported stock cylinder, I would consider fattys, but believe it or not my builder set up my engine and jetting to where it has almost the same initial snap as the fattys, it’s pretty crazy, but of course they scream up top, a lot of people say that shearers have no bottom, but if your builder knows how to port, jet, set timing, compression for them, they hit hard.
The Fatty's were recommended by my engine builder for my setup. They come on sooner than the Shearers which I like and pull great in the Midrange. The Shearers pull way longer on top which really don't help me for dune open riding.... maybe if I was in Glamis where the dunes are longer but in Oregon everything is short hill climbs. Fatty's are a great pipe on a Banshee and cheap!!
That’s good man, cameron knows his stuff that’s for sure, I forgot to tell you that I’m on 18cc domes, so I’m on straight race fuel, another reason why my setup has more snap as well for having shearers.
I'm running 24cc pump gas domes so yeah more compression makes a difference.
West Coast Roller you should look into slp pipes, they come on hard, but almost make as much hp as a Shearer and CPI pipe, but they make that hp much lower in the rpm curve, so not much overrev, but the power is there, perfect for your style of riding. I only ride a couple times a year at most, so the expense with race gas is no big deal, but if you ride a lot, I could see why you went with a pump gas setup, but the torque curve is much stronger on race gas. I don’t have those clearance issues with my 39mm pwks when it comes to the stinger tubes, I think it’s because I’m running the billet intakes which keeps some decent space between the filters and tubes, they seem to be angled lower, so no melting issues there. My builder is Eric Friend from empire industries, he knows Cameron because Eric started in Oregon back in the 1990s by the name of white knuckle racing, I believe he was out of Boring, now he does custom pipes for 4 strokes, he’s in lake havasu now, that’s pretty much his work now, no more engine building, but he sure knows his stuff if he ever had to do a build again. He left my bike running real sharp, engine so balanced, jetting spot on, great build overall, now I just need to get my gearing dialed in, but that’s all test and tune. Dumont dunes is my spot for riding, smaller than glamis, but not as many people, better for hill shooting, the dunes are dangerous though, horrible angle with the razorbacks, plus it’s about 100 miles away from Vegas, so you’re for sure getting air lifted if anything major happens, no hospitals nearby there.
I've heard good things about the SLP. Haven't tried them. Sniper seems to be the all rage pipe on a serval but all that matters to me is that the pipe makes power where I want it. Thanks for the tip on the billet intakes. I tried a Chariot briefly but ended up returning it due to some crappy design with the crossover plate I didn't like. I would buy a Mattoon next time. The UPP's rub with the Shearer pipes & K&N 6 inch filters. No rubbing with the FMF's.
My buddy had a cub built by Eric when he was in Oregon. Cam is my go to guy but he is only 2 hours from me. Never rode Dumont but I have been there. Wouldn't want to get injured there that's for sure!
421c bb shears love the topend just brought me some t5 the bottom came to life I also have a set of fatty I love to try out
Fatty might have slightly more bottom compared to T5 have to try them all out to see which one you like best but the shearer is definitely a top end drag pipe hands down.
@@WestCoastRoller i will once the spring come around also have a set of dmc916 i am goin to try out this spring can't wait 😀
Tip for the pipes and filters. Silicone hose around the pipe. Think it’s 1” that fits
Yes I just bought some 1" silicone heater hose
Did you go from stock cylinders to the 421? If so how much of a difference did you notice? Thinking of porting the stock or buying the assasins 421’s
If your budget allows it go straight to the 421......otherwise ported cylinders are best bang for your buck.
A ported 421 serval will be more torque and power than stock cylinders....a wheelie machine.
Thanks for the video. I have fattys now and am debating on whether or not to keep them when I build the 421. Mostly a trail bike but will see some drags/sand. Where were you riding in the shearer clip? Looks awesome.
I think I was in Florence oregon riding in that clip. I would definitely try the fattys out on the larger motor. Mine rip down low and have a very good top pull as well. I'm still experimenting with both pipes mostly jetting to get the best performance. I'll do an updated video eventually with what I decided. Thanks for your comment
@@WestCoastRoller Thanks again. Looking forward to the video.
Ive run pro circuit and snipers on a serval and the snipers had just as much low but way more top
Its more the jetting than the pipe
Found the cel needle on the 2nd lean but with the top end of the needle sandpapered in a rotary tool to 1 stage richer(as if needle was in mid clip )was better than anything
That way the needle cleaned up bottom end but didnt lean mid top and then ran 152 main and 48 p
The dyno confirmed with a 12,5 af
yes jetting is key to performance and all how you like it to run...thanks for sharing
I will speak from experience, that it would be better to bolt at the canister vs the pipe.
I had a tab rip off on my turbine cores on my banshee mounted the way yours are.
Bad ass bike bud
I'll be bolting them on at the canisters so they will be more solid mounted. Pies vibrate alot on a Banshee!
Thanks for your comment
West Coast Roller you’re running a serval right? How do you like it? I’m waiting on the parts to show up to build mine
@@stevencarter3290 It's great! Alot more potential power than say ported stock cylinders. I'm somewhere between 85 -90 HP on pump fuel. All depends on what kind I'd power you want to make for your style of riding.
West Coast Roller mine will be set up for race fuel. Will probably change pipes later. And do some 35pwks
Where did you get the water temp gauge? What a great idea.
Redline racing sells them on their website or Rocky Mountain atv should have them as well.
You runningV Force 4s? And have a link for that tank?
yes V force 4............clarkemfg.com/tanks/catalog/yamaha/banshee-350-all-5-5gal-11420/
WhT helmet mount are you using for gopro
It was mounted on top of helmet
I did purchase the velcro gooro mount that wraps around mouthguard
Im running a bone stock banshee, carbs, bore, and all. Im going with the fmf fattys, but am uncertain about the carb jetting. Wondet what jets i go to?
Couple questions......what is your elevation? What type air filters?....Pods or stock in the airbox?
@@WestCoastRoller stock airbox with foam filter. Elevation around 2500 ft.
I would go with 280 mains, 3rd or 4th clip stock needle, stock 25 pilot.
Air screw 1.5 turns out from seated.....you can fine tune the air screws from that setting in or out when tuning off the bottom performance and reving.......make sure your carbs are synced up with each other or it will throw everything off. Buying a syncrometer tool is money well spent to set your idle....slides generally can be set by visually looking to make sure they both open evenly. There are also sight windows on each carb. If you don't mess with anything other than just changing main jets you shouldn't have to do the following. South Texas Banshee youtube channel has good videos showing how to do all of that.
@@WestCoastRoller thanks allot for the info, greatly appreciated
What petrol tank is that?
Clarke
Where did u get that tank at !
Clarke Manufacturing in Oregon
Is that a stock length swingarm
+4
Where do you buy your fuel at?
pump gas 92 octane
The only thing I have about the banshees is the damn wiring that connects from the stator to the cdi!!!! It looks like poop then when you try hiding it hits the pipe!!!
I used plastic wire harness protector and routed it from the stator to the rectifier. No more wire chaffing.
West Coast Roller I’ll give that a try
Those silencers and stringers are hard to find. Now obsolete.
I still have them....yes they will keep going up in price if they never make them in production again...I heard they were going to but nothing has materialized from the new cascade owners.
SHEARERS SOUND A LOT BETTER.
shearers are larger head pipe diameter than the FMF's
Wanna sell the shearers ?
No but if I decide to I'll let you know thanks.
Ok thanks
What are the pegs off of?
2009 or newer yfz450R....I made a video of them it's up on the channel! 👍
I thought it was you.. I've watched quite a few videos trying to find it. Much appreciated sir
@@WestCoastRoller is that a direct bolt up?

Toomey T5's are a much better pipes for just about everything over FMF
.everyone has a favorite pipe.... they all hit a little different according to dyno runs...happy riding.
@@WestCoastRoller i think if you like trails and racing you'll like the T5 i have 2 banshees 1 with t5 and other fattys and id take the t5 everyday
I haven't tried the T5' on this motor...the fatties have a good low end pull and they do pull hard on top surprisingly...I'd like to do a comparison test to the T5 someday....on my video list.
@@WestCoastRoller ive had paul turners, fmf fattys and T5s so far the t5s are my favorite for what they are but ive heard the stage 4 trinitys are just like t5s
Shearer’s won
For all out top end power...yes. For midrange.... fail.
Honestly if your motor is not built you're not going to gain anything with either pipe sufficient I mean you might gain 3 horsepower if that
Its so annoying to hear people call them a bannchee.
Thanks for watching Brian Bannchee
