supercharged yfz

[fuelcustoms]

@badbanshee1 WOW! You must have the badest lawnmower in town then!

[badbanshee1]

4strokes sound like fucking lawnmowers!

[kill2liveman]

@badbanshee1 2stroke sound like weed eaters what do expect

[binkaslt]

My bad its really yfz

[binkaslt]

Its honda TRX,not yamaha! Dunlop tires,original from fabric..

[green2stroke]

@binkaslt ur a retard look at the jug on the motor its a yfz

[quadracer1243]

@binkaslt honda, suzuki, yamaha, kawasaki, pretty much all the makers use dunlop stock, so no, its a yfz.......

[p3kranger98]

wait isnt a superchager a fan thing that forces air into the intake?

[r1i1o1]

Nothing is wrong with the quad its a powersurge from the supercharge and i would say a cam too

[mountianbikeer]

fuck man id trade my 700 grizzly for that any day

[trx400r6]

i used to race for rossier! haha i live about 20 minutes from the shop... you can actually get a roddier pipe for just about anything.... just call the shop and ask for joe and tell him what you want and he will make it... everything is done on a flow bench to make the most HP possible...

[YFZRIDR91]

what kind of exhaust it that, it sounds really nice

[fuelcustoms]

Its a rossier. very nice exhaust system

[petthekittyz]

why not just mod a raptor?!?!?!???!?!!!!??

[penorwrinkle]

cuse this is a better quad

[petthekittyz]

its the SAME CHASSIS, the raptor has a bigger better engine, that isn't legal in GNCC racing...

superchargers aren't legal either...

why not start with the better engine?

tuning fuel injection is much simpler, the hp created with forced induction would be MUCH higher on 700cc, and in no way is the 450 a better quad, its just different.

[ajd2466]

horsepower or cc is what sells a quad, torque is what wins races

[petthekittyz]

@ajd2466

and torque comes, usually, from displacement.

I'm sure this thing is a blast to drive, but moding a fuel injected raptor is soo much easier!

[bitedummy]

@petthekittyz Sorry but the Raptor Chassis and the YFZ chassis are not the same

They are not even close. The raptor is legal in several gncc classes and race against 450's all the time. Also the five valve system in the yfz is far superior to that of the 4 valve system in the raptor which is outdated. Im not sure where u get your info but most of it is off. The yamaha 450 motor is state of the art check your sources

[petthekittyz]

@bitedummy No shit the 450 is badass, but not for boost, you dont take a low displacement high compression engine to boost.

yamaha has been doing the 5 valve thing for years! my R1 has it, and now they have gone back to 4 valves because they realized the increased valvetrain is using more energy than it is making.

[bitedummy]

@petthekittyz you are right yamaha has been doing the five valve system for years since 1984 to be exact. They have recently switched to four valves in their fuel injected systems due to efficiency. That much is correct . They claim that while the five valve system is capable of much more power and stronger bottom end that the increased mass makes power less controllable. I do see your point as far as displacement but I dont think it is as simple when your talking YFZ450 vs. Rappy 700.

[petthekittyz]

@bitedummy when it comes to spending the money on pushing forced induction into an atv, there is no question the raptor is the better application. I'm not saying its the better quad, but the engine, valve timming, compression, displacement, fuel injection, everything about it is SOO much better for boosting, I cannot fathom boosting a 450 dual cam with 11:1 compression.

[moinvestment]

@petthekittyz is there any way to supercharge a 125 Chinese made ATV. just wanted to know if i can add major power to it.

[petthekittyz]

@moinvestment You would likely have to modify the case, somewhere, in order to pull power from the crank to spin the supercharger, usually directly from the case but could pull power from cam or anywhere that is powered directly from the rotation of the crank. Turbo would be a much better forced induction application for random application, although I would recommend getting a larger engine, or selling it and getting a bigger bike for best all around everything

[jmb145]

@petthekittyz cuz they have HORRIBLE bottom ends

[petthekittyz]

@jmb145 the YZF does?

no doubt, but the raptor would take to the mods better, MUCH better

[kayla72409]

@YFZRIDR91 it a boobo pipe

[moto38rider29]

sounds amazing

[TheBiggamer16]

looks like the exhaust is upsode down haha

[mxer4life21]

lovin the blower surge sounds badass

[rcbadazz]

ok i need help my friend just bought a second hand quad and we were wondering if it is jetted any1 know how we can check? its a yfz 450 btw.

[fuelcustoms]

Does it run good? If does then i wouldnt worry about it. Check the end of the exhuast pipe, is i really black or greyish to white color..?

[1FMF2]

@fuelcustoms Hey random a bit here my warrior has black? is that bad

[digzie1]

if its runnin pretty hot or poping alot when you let off the throttle, its lean

get bigger jets or raise the needle ! if it bogs alot its too rich.......

[countryboyG]

i have a 1985 honda trx 250 fourtrax and it runs hot and pops alot but if i push on the throttle too much it wants to shut off what should i do o.O

[digzie1]

if ur yankin my chain-lol if your serious, sounds like its lean if it ran good and just started i would

clean the carb first, probably loaded with

dirt, ive also seen the float needle get

fuel tarnish-varnish (covered with gunk)

and stick,then it will idle great but when

you take off it wants to run out of fuel and get HOT, clean clean clean......

"countryboyG"

[countryboyG]

lol ur too late!! i already did that and i adjusted the needle up one so its giving it more gas and its running better than ever i spun the tires through all five going down the lane my brothers having this problem now so im going to try to clean his carb.

[digzie1]

sweet !

[450God]

thats amazing

[YFZRIDR91]

how do you get it to idle like that, is it a stroker crank?

[kevjt]

It's called blower surge.Most engines with with a supergharge does that at a low idle.

[metalalien79]

love it... I love the way the engine breathes when at idle... my bike does that same thing..
