[Group] YAMAHA Fazer

[SiaoSter]

it was $80. not sure if it's the cheapest but still better than $140 at HKL, $120 at racewerks n $280 at AMK. i asked bikeworkz as well n they quote around $60-$70 but requires half a day to do it. Unique did it in half an hour......they said for FZ its easy cos no need to cut or re-weld anything. just take off the end can n mid pipe n knock the honey comb off......

 

the airbox mod.....hhmmmm....i'm not aware of it till now.....haiz.....

 

 

They didn't advice whether issit good to have the airbox mod?

[konspire]

So u decat ur midpipe? Me tomorrow thot of sending my fz6 for engine oil, spark plugs, brake pads, coolant change. If got xtra time would like to decat also the mid pipe or change to scorpion exhaust. All because bonus come in lor. Huhu

 

my cat is at the front header, at the end of it. midpipe onwards all hollow. where u doing the servicing? my personal advice, i've heard FZ6 with twin scorpion installed. like no sound ley.....unless u want quiet quiet la......if not LV or others that sounds more nicer....

[konspire]

They didn't advice whether issit good to have the airbox mod?

 

on my DRZ yes but not on the FZ.....now i'm asking if they do it or not.......if yes, then after work return lor......do it one shot....

[konspire]

bro, LV pipe comes with a decat midpipe:angel:

 

evil sia.....

[Yatz86]

evil sia.....

 

how can say evil.......i very guai guai one:cheeky:

[konspire]

They didn't advice whether issit good to have the airbox mod?

 

ok, they replied. they asked me to ride n feel first after this de-cat. aftermarket air filter should be ok as the air flow is much better. i think that's why i felt no more popping sound.....but the popping sound make it more fierce ley....

[SiaoSter]

on my DRZ yes but not on the FZ.....now i'm asking if they do it or not.......if yes, then after work return lor......do it one shot....

 

What abt adding of pc?

[konspire]

how can say evil.......i very guai guai one:cheeky:

 

yeah rite....n for ur best interest, if u ever need to park overnite at the "MSCP" again, make sure u put coupon hor....cos that area, the stealth parking warden usually do their rounds at midnite to 2 am n they drive car one, private car hor....so they r very stealth......tips jus for u la......n applies to whichever comes first....

[konspire]

What abt adding of pc?

 

as what i got from our superbike mechanic cum lacer ah dolf last nite, he said putting PC is always good n dynotune it as well.......unique didn't recommend me as they know i'm not that hardcore....hehehehe......just nice nice here...syok syok there.....

ya lo...i also saw once the fong fei fei drive a normal saloon car....stun liao....but park there quite okie luh....this year only tio once there..

Thats true enuff.....as we discuss yest, Bro SprSpeed Offered WaveFan to do it DIY as long thers tools to get it done plus the AirBox Mod too......hahaha. $80 seems its in the middle price Tag but shld be ok Since 30mins itz Done......If only i was there juz now, Confirm u get yr Airbox Oso Done.....heheheheikz

 

DIY bro, with the help from the superb buddy cum adviser, a 15-20 min job...

i did these (AIS, air box mod, flies, v-stacks & cable re-route) a week before my akra arrived and change air filter & de-cat while fixing my akra...

something like that la...

 

Hah ! guess it.......as i could recall in the older post, u did some mods whilst yr Akra was arrivin to be part of your Black Angel. Nicely planned and done !!! Upzz.....

just to decat the header area $280? or stock pipe also decat? i decat my stock midpipe for less than $100, + other things done also.

 

decap stock mid pipe + labour only.

hahaha...poisonous sia u.....if meet u must wear ear muffs....those used for aircraft repairing ones.......

 

no la. in the end they told me aftermarket should be enough pushing the air through........they are the mechs so i trust them......then i trust my butt to get feedback from the bike....

bro, if you like to decat your stock, let me know.

 

anyway for those thinking about doing airbox/air intake/ram air mods;

 

1. The ducting needs to be very smooth on the inside with no sharp bends or rough surfaces. You want smooth (laminar) airflow for the entire distance.

 

2. Location of the intakes is critical. You need to find a location that sees high air pressure while riding. You could check this out by mounting a sensitive pressure gauge to the bike with a hose going to the place where you want your air scoop. Go for a ride and note the air pressure at a set speed. Compare with other locations.

 

3. Crosswinds can create a venturi effect across the intake opening. This will reduce the airbox pressure. (It's like blowing across the top of a beer bottle.) This is why modern ram air intakes have more than one opening, to compensate for the crosswinds. One of the original ram air bikes had a single opening and crosswinds created a dip in power that could be felt by the rider.

 

4. The opening needs to start small and smoothly increase in cross section as it approaches the airbox. The reason for this is that you want to smoothly decelerate the air as it approaches the airbox. This is counterintuitive at first.

 

The air at high speed has a lot of energy. It's flowing through a narrow pipe. As the pipe widens, the air slows down because it no longer has to flow through a narrow pipe. The wider pipe can handle the same amount of air at a slower speed.

 

Conservation of energy states that the kinetic energy of the air has to go somewhere. It is converted into potential energy in the form of higher air pressure.

 

A sudden increase in size does no good, as the airflow becomes turbulent. It needs to keep flowing smoothly to make a good transition.

 

Another way to look at it is by thinking about Bernouli's principle. Faster moving air has a lower pressure that slower moving air.

 

If the bike is moving at 70mph, than the air entering the ducting is moving at 70mph. And it's at 14.7 PSI (Atmospheric pressure.) As the duct widens it begins to slow down. Since it's slower, its pressure is higher. And high pressure is the name of the game.

 

So to summarize, what you need is smooth ducting from the front of the fairing, with no kinks or sharp bends, into the airbox via two ducts that increase in size as they approach the airbox.

 

The only way I can see to do this would be to cut holes in the frame and route ducts through them. You get into issues with weakening the frame when you do this, so plan on reinforcing the cut areas.

 

The fake scoops on the front of the fairing might work for ram air, but I suspect that they're too far back to work properly. Better to build all new scoops that mount below the headlights.

 

Once your ram air system is working, you'll most likely have to retune to take advantage of it. The stock ECU might be able to handle it OK, but don't count on it. Yamaha didn't plan on ram air with the FZ6. It may not know how to respond to pressures above one atmosphere. The MAP sensor may not even be able to read pressures above one atmosphere.

 

It would be a serious project to make this work. In many ways, it would be simpler to just fit a turbocharger! The plumbing is not as complex and the power returns are several orders of magnitude greater.

nO wOrries.....i got antidodes for minor poison infection. Im still a Newbie....lots of things to be learnt and understood Before doink sum Mods on my own bike. If i do and do.......den skali 1 new rider come by me and ask each of the function of my Mods....den i do know whats its use MALU liaoo !?! Confirm may face red all the way....Paiseyy like Hell.

 

 

Heyy bro......abt the JB Petrol Ssion . Im goink Tmrw Midnite wif my clicks......sorry cnnot make it after work hours, got an Appoinmnt in the North. Or Else u can Buzz me around.......hmm u noe who rides the Naked FZ1 that always parked at the Pavemnt near the Basktball Crt ??? Or is dat u.....hahaha sorrie KPO again.

reading the points makes me felt that i'm going thru lectures again sia........

[ghost04]

i just did an impulsive buy...

i bought a bagster tankbra+ DNA air filter at motoworld just now...

then my mech called me he ordered BMC air filter for me liao...

so now suddenly i got 2 air filters....

so anyone interested in the DNA air filter?? $100 take n go!!

btw its for FZ1 2006 onwards...

hahaha...antidotes ah...must need a very strong one.....maybe a whole suit condom.....if ppl ask just redirect them to Charles or ah dolf lor.....or the seniors here....just make a reference...hahaha....

 

ok la...next time then. cannot go midnite, i still hv my research paper to do n cannot afford to sleep late due to work in the early morning. for the naked fazer.....i didn't realise there is a new on parked there. so far, it's only the grey S version parked at 351. mine is S version, not naked. i also just realised last nite my MSCP has a new fazer1 S version wif box starts to park there......

u went to motoworld @ lavender? me n charles were there at lunch time..

lol no...i was at kaki bukit...

[konspire]

hahaha...so i guess every one of us were having a bikeshop lunch just now.....only different bikeshop....

[dolf]

Interesting topic today hahaha.. I think there's been a big misunderstanding, I only supply tools:)

decap stock mid pipe + labour only.

 

Decat the muffler is much more involved than the midpipe as you have to cut the muffler to get to the cat in the link pipe, right after the exahust valve. Throttle feels lighter and nicer/louder grunt. Not as loud as some aftermarket slipons with no baffles. Even with the carbon covers, it's cheaper than buying a slipon. You don't get much of the weight savings though but I like the shape of the stock can and with the sound level, road safe
