the only part of my quad that i haven't had apart is the carb.. that will be very soon tho:no: my airfilter took a dump :fart:in the last race and now i've lost some compression, not sure how much, but i can tell a diff in the way it sounds and feels. it's not smoking, but i'm not going to give it the chance!! I think its time for a GYTR high comp piston, GYTR full stainless exhaust, and GYTR air filter and jet kit:cheer2: that should bump it over the 65+ HP mark:wink: gonna be some dough tho!!!!!!!!!!!!!!!!!!!! atleast i'll have an excuse to tweak the carb!

So While your in there YFZ450.................. check on some of the GYTR stuff, its high, but its the best!

Oh yeah, if you do more screaming than lugging, be sure to retard the exhaust cam one tooth from factory settings to give it the YZF style topend, it will cause it to be alil more cold natured but will really wake it up on top end.

I just got thru going thru the headache of the left case my self:aargh: i did all the work in a friends basement(minus machine shop work) it is a pain, but it's not that bad with a repair manual. after all the research i've done, from 04 to 08 all parts are interchangeble, some parts have improved since 06:yes: some have degressed since then(i cant verify it, but i beleive they changed the piston for better reliablity, and i beleive a loss of power) but thats just my :twocents:. the change in the cases is a plus. the 06 up has an added oil jet that lubes the bottom of the piston:yes: but you can get a kit to upgrade the 04/05 cases too. i'm not sure exactly about dirtbike to quad conversions, but I dont believe so.. the YZ has a smaller flywheel and stator, the YFZmotor is based on the WR version, but i dont know how close, i think the cases are different due to lack of oil res on the dirtbike.. DK for sure...

alright for the task at hand..... the cases are matched from the factory:aargh: so you have to have a matching set to ensure proper alignment of everything (bearings and coolant chambers).. after the head and jug are off, if you dont have access to any special tools, leave the fly wheel ON the crank if it doesnt come off easily your supposed to have a puller to do it properly..(left side) the engine disassembles from the right side Up:bangheadc: the left case is the "base" so after you remove the right cases,(inner and outer) and the tranny,,,,, whether you got the fly wheel off or not you then take your old left case to somebody that has the tools and the stuff to Press the old crank off of the old left case and press it into the new case:rantc: be sure to have the head and valves checked and adjusted while its off and easy:wink: be sure to lube, loctite and torque every thing to spec, and stay calm while reasembling the tranny shift forks and shifting drum:err:..

Good luck with it! Keep me up to date on your project! Holla if you got any questions, I do the best i can to help out!! I'm out of breath right now..lol

Keep a close eye on your oil level!!!!!!!! i just got through replacing my cases this spring on mine due to my chain coming off and busting around the clutch shaft:no: I got a set of used cases off ebay for around $150.. you can get a new set for around $300. just keep an eye on your oil, keep a light left foot, and just remember, if you ride on hills, the faster it will dump!! good luck with it! keep us posted!!

hey, i just fixed that issue on my 450, it would do nothing but turn for a second and start clicking even hooked to the charger.. that really baffled me, i even got a new solenoid with no luck, but if i bypassed it with a wrench it would fire right up, there is a starter relay tho!! mine was burnt up and causing the low voltage on the trip wire to solenoid!! that sounds like your prob too. I found one off a warrior that fixed mine!! but from yamaha their only $16 new! i would definately try that first!

I was an after school varsity cheerleader coach and personal trainer:cheer::cheer: she was a pro! ..she didn't make it to state in 02 tho, she kinda had more important things to deal with..:rolleyes:(Mini-Me)!

It must suck to get beat by a black boy with hemorrhoids????lol!!!!!!!:smackbum::doa16:

lol... i have no room to talk, i only got to play little league baseball.. football interfered with my families deer season:no:

if your really looking for a deal on tires keep an eye on ebay for a set of razr or razr II take offs from a race team. i got a set of razr2 fronts on baja rims and razr rears on ITP 10" beadlocks for $191 (after shipping)off there with 75% tread and no holes!!! Racers post them at decent prices to and sometimes you can even find them with up to 90% tread left, i know some teams that dont put more than 2 races on a set then sell them for that fresh edge on the lugs. keep an eye out on there you never know what you might stumble across.. I would go with maxxis over the ITP holeshots, they have a lot more durable compund, and get awesome traction too!! Good luck, and great job on the silver bullet!! i'm going to take a nap now from getting caught up on this novel of a post..lol. take care!:bow:

what year is your YFZ? I run stock 08 shocks on my o5, the 07 BB edition has the better shocks to. The stock shocks can be revalved and resprung(by the right ppl) to compensate for your a-arms and will handle just as good as the elkas, they can even be extended for longer travel.. and that runs around $800 all the way around. but as for elkas, if in doubt and you can afford it, go with the better ones, the what ifs dont hurt as bad..

best racing pic(definately!)... ugliest quad pic(lol).. wildest injury or scar pic....... stunts...etc...

Do any of the other gears Pull?? that sounds like the classic 660 tranny nightmare:confused: if its not your clutch, 3rd gear is the most common to drop first, but not all the time, especially if rode hard or raced. Good luck with that aspect. now the rev box is a different story, they not only extend the revs, but they also change the spark curve, if it doesnt sound right, then its probably not right, changes in timing could cause other existing issues to surface(leaky valves, piston slap) but also they could be more minor like air/fuel mix or octane deficiencies causing spark knock from the newer more progressive spark timing. Good luck with it! Keep us posted!

:beatdeadhorse5c: why dont they go try to levitate the poor up off the couch so they can make their own money...

Get A CLUE People!!

wow, i didnt see how old this post was!! Well what did you end up doing??

i have a straight DS. i love it, (well whats left of it anyway) I've definately got my moneys worth out of it! it is unstoppable!! except for the stock battery, and i've broken 4 stock front shocks, and the rear is busted at this time.. But technically the frame should be broke and i should be dead as hard as it has landed! never bent an axle tho.. Motor is cold natured but once warm, cranks instantly, very easy to ride.. they're just not the rig for jumping 90 foot triples:wink:.lol It makes for good war stories tho!! Good Luck, let me know if you want to know anything.. I'm about to tear mine down for a ring and a valve job due to cracked intake boot:mad: Good luck and stay safe!
