dude there is no way your bike is only putting out only 59hp and if it is then I'd sugest finding someone else to do your mods

Ya because his bike has only won 2 four stroke wars in its class,and MMAD his builder.The bikes he setup only won king of the hill and damn near every class they entered.But hey whos counting.Must be the 5/8 fuel line

dude there is no way your bike is only putting out only 59hp and if it is then I'd sugest finding someone else to do your mods.

My bike dinoed out at 57hp after putting on a DMC, edlebrock carb with 5/8in fuel line , full aluminum intake with a K&N, and running a fuel mixture of 2/3 110oc 1/3 100oc, and I run all redline fluids.

after that I put the rev box on, custom made cams, redid the VVT to match the the Toyota celica GT motor, and played with the sprockets on the dino tell my hp topped out.

(If your looking for custom mods look tawrds the celica GT, the motor that is in the 450 is the #1 cylinder on the GT motor)

No offense but that is a very crappy setup,i guarantee your bike isnt putting out nowhere near 60hp.Thats just crazy.Whoever dynoed your bike,his dyno must be reading 20hp high.I have tons of experience with YFZ's and you have to have a high dollar build to make 60+HP on a 450 based quad.Ive dumped a pretty penny into mine along with plenty of testing and it runs very hard but isnt making 60hp,maybe 54-56ish if im lucky.1badyfz has one of the fastest stockbores in the country for example and is making 59hp.Whoever told you your bike dyno'ed 62HP should be slapped.

lets race for titles if your so sure that its impossible...

Ill take you up on that say when.I agree,thats total bullcrap.I have a built yfz thats very fast and it sure as hell isnt putting out 62hp.

Only 9 views,hope you guys are running your stock flywheels,lmao!!!

Over Presidents Day weekend a friend of mine was at Dumont racing up the hill when his 04 trx450r stalled out.He couldnt get it re started and felt like it had low compression so he called it a day.When he got home he pulled the head checked the topend and replaced the gaskets but it wouldnt start still.Then he figured out it had no spark.Thats what led to checking the stator and flywheel.Thats when he discovered the 2 piece flywheel.He has been running it for about a year.It was on a built stockbore.It was shocking to see this.What could have caused this.

:shocker: :shocker: :shocker: :shocker: :shocker: :shocker: :shocker: :shocker:

What do you think??

I see you made it to dumont.How did it run?

After the sandrail crash in the bowl,everyone scattered and alot of us got left behind.I had to go after that,and didnt get a chance to say bye.That was a really fun day.Perfect weather.

Ive ran both comp cut padla brats,haulers and UL Haulers.The padla brats are 10x better duning tire than the haulers.They slide way better and are the lightest sand tire you can get.If you are worried about holes dont get them grooved.I duned my comp cut brats for a very long time with no holes,they are a 4 ply tire.They also offer tire slime in them incase they do puncture.If you are careful not to blatantly run things over it wont be a problem..The padla brats are the BEST all around performing tire hands down.The best hillshooting tire IMO is the UL haulers.I dune my 22" haulers and its no walk in the park because all the sidewall flex.If you go with a regular or UL hauler i would recommend a 21" 6 cup on 8x7 or 8x8 wheels.If you get padla brats i would get 6 cup comps on 8x7 wheels.The brats cant match the top speed of the haulers and the haulers arent are nice to dune as the brats.Pick your preference and get them.I would order them from Fullerton Sand Sports.You can get there number in the search on the net.Ask for Joe.He has both haulers and brats in stock with a nice variety of wheel sizes.

cool vid the girl on the raptor was kicking everyones tail or was that the yfz 450 i know there real similar now

The girl you see me racing over and over is ruth from utah,she has a built up yfz as well.She won the womens class at 4 Stroke Wars last year.Best female rider/racer ive seen.

sweet video from tech with its last day in action.

Music

I think this is the tune you were looking for JK ..Man be careful,i keep having this vision in my head of that belt snapping and slapping you across the face For performance sake i hope it works,that would be awesome

IT'S ABOUT TIME!!!

I really miss duning with some of the old school peeps like yourself, Aaron. The bike looks sweet and I can't wait to do some riding next trip out. All we have to do now is get Mike B back out there (yeah good luck) along with other peeps we used to ride with (Smitty, Justin, Chris Jones, & hell even Dave Reynolds haha) and we'll have a damn fun group of peeps to ride with along with some of the cool mofos we've met on DDR. :xmas_lipsrsealed:

When is your next trip out?

Im hoping to atleast daytrip new years...You know 4 stroke wars is at dumont this year in January dont you. After new years that will be the next trip.I cant wait to test it out.It should be sweet.

I just got finished taking a couple steps back from hillshooting .I ditched most of my drag parts to get back to duner status.I ditched my billet axle for a Durablue x-33.I ditched my Woods drag pipe for a Sparks big core.I also ditched my Shaws for some Elka Dune Editions.The motor is still the same :xmas_lipsrsealed: Mostly just some chassis switches to make it a nice riding duner.Hillshooting is in my blood but i really missed duning.So i had to meet somewhere in the middle.It will still haul a$$ up the hills but it is totally duneable and i can finally jump again.I took my Elkas and polished the red out of them.I painted the header with a high heat paint and polished the silencer.I also cut the turndown style cap on it.The X-33 looks real nice with the chrome and also has the billet hubs.Last trip out i was pretty bummed when Pete and Bert tried to get me to go duning but i couldnt with the shaws because the dunes were so rough.So after that i decided i would take a few steps back from the drag stuff.Here are a few pics of what i did.

Polished Elkas

X-33

Sparks Big core before end cap trimmage

After

Im really looking forward to some haulin a$$ dune rides,its been a while

The turbo bikes ive seen run werent impressive and most were on nitrous too,they took too long to spool up and by the time they did the race was over.Im sure they will get them working eventually and be awesome but until then save your money.

here is a link for some comp cut padla brats with wheels.he is asking 325 shipped which is about 100 less than new.

call fullerton sand sports,they can get you haulers in any size,they also sell the best all around tire on the planet for dunes,the 21x12x8 6 cup comp cut sand tires unlimited padla brats.For pure duning the sand skate 1 on a 20x10x10 wheel is awesome.If you go with haulers i would get a 21x12x8 6 cup regular hauler.Call and ask for Joe.....714-898-2049

i have never seen a fast predator at dumont or glamis :yeah_whatever: are we talking fast in a straight away race,or up a hill?my friend sold his predator for a yfz and said the predator was a total turd compared to his yfz.ive seen some fast ones in the midwest that nicholas cycle built but none out west.

I just wanted to clarify what i meant in my QOTM post to nick(ISBB).What i was saying wasnt about the past winners,lol.I was talking about i understood the frustration of for example onefastkawies bike having a laundry list of mods and not getting many votes as opposed to girlwithhorns not so flashy bike almost beating mine for QOTM.I am very happy to have won and think the people that have won in the past have deserved it IMO.At the same time though its a public forum vote and thats the way it goes.Another thing you might consider is a picture of the month contest.Lots of sick pictures get snapped all the time and would be cool to have on the front page.Anyway the old QOTM thread got locked so i just wanted to clarify what i meant.

yea thats what i have heard. i am hoping to find someone at dumont on thanks giving that has a set that will fit my ltr to try out. or try there bike but we will see. just wish i had known before i spent 300 on the set i have know

Dont feel bad ive spent thousands trying different tire,pipe,and motor combo's.When i first started i had no clue what worked good with my YFZ.The more i read on the internet i finally started understanding what i needed to do.All i can say is EBAY!!!I would just sell my old stuff on ebay and buy what i needed.I can tell you right now what the difference will be by changing your rear tires.Your bike will accelerate and pull each gear longer with the 21x12x8 6 cup haulers.On dune rides it will take a little more effort to turn but your bike will run so much better overall you wont care.If you want the best overall hill/dune tire get the Sand tires unlimited comp cut 21x12x8 padla brats on a 8x7 wheel.They are pricey at $400 a set but are the lightest tire on the market and dune way better than haulers.If you want to save money just get the 6 cup regular haulers on a 8x8 wheel.They are alot cheaper,just dont quite dune as good as the brats.Ive had both and the brats are the best all around tire,and just give up a hair on the hill.I sold mine to get a taller tire for hillshooting.What you are running now is ok,just limited in what they can do.You can do alot more gearing wise with the 21x12x8 haulers,and the brats are so light(9.5lbs each with the wheel)You can get away with taller gearing and still run the hills very hard.You will notice a very big difference in the way your bike runs just by changing to a lighter tire setup.Night and day....

I was running a 13/36 on my 06 ltr with a 20x10x10 extream 7 paddle

i just put a 38 rear on it so we will see how it does now at thanksgiving. from what i have heard fullerton sold me the wrong tires. everyone says i should be running a 21x12x8 tires

Ya 20x10x10 7 cup extremes are a good duning tire,but 21x12x8 haulers will give you alot better mph up the hills.If you decide to change them i would go with a 21x12x8 6 cup regular hauler.You really dont need extremes.6 cups will also make duning a little more pleasant on an 8" wheel.The tires you are running now are about the slowest style haulers for the hill speeds,not to mention alot heavier.By cutting down the rotational mass on the rear end your quad will accelerate much quicker which makes all of your duning more enjoyeable.

I was wonderin if anyt of you guys change your gearing for the dunes .... I have a 06 trx 450r , i run 14/38 in the desert and dune's i can pull comp in 3rd sometimes 4th ...stock is 13/38 ..........but it seemed too low in the desert i was always searchin for a higher gear in 5th ...........So should i try different gearing for dunes to pull 4th?? or will it be the same as runnin 3rd with the gearing i have now?? Sorry for all the questions just i've never messed with gearing ........

Also what kind of bike do you have and what gearing are you runnin??

Dude i thought you had a REAL quad A REAL quad pulls 4th no problem,even with a 240lb rider,LMAO!!!......JK.... Seriously though if you are close to pulling 4th with a 14-38 you should start adjusting your rear sprocket to fine tune it.Maybe a 14-39 or a 14-40 depending on how much more you need.Dropping teeth on the front sprocket on the 450's is usually overkill and overdoes whatever you are shooting for.Good Luck.

OK, we now have an official Halloween banner I made up. :dunce:

Don, I'll add it to your post in the beginning of this thread.

I can't wait for some night time fun at comp! :shocked2:

Nice Banner Pete!!! Ill be out for the day,if im lucky ill be able to stick around for the night fun too

Man i had a super fun time.Im really sorry i didnt get to hang out and talk to you guys more,but i only had 4-5hrs to stay and ride.Hopefully im freed up for Halloween and can visit more.Awesome Pics Pete!!!You guys have grown into a huge camp,its pretty awesome To think a few years ago there were like 5-6 trailers and now how big it is...Pretty cool.

Dyno...you dont need no stinkin dyno :freakin_nuts: My 450 has never seen a dyno yet.All my tuning was done on the a$$ dyno.

That turd will need all the spray it can get to run with a piped YFZ
