Hooligan

Try this maxmekker.com I honestly don't know how much was changed from 05 to the current version.

I googled the one for mine and found a lot of downloads, but since have found some fellow riders who have good versions to share.

The main issue is that the page essentially loads, but does not display the page content and images sometimes. Example: I can access a page, but the screen will be completely white or will still display the previous web sites content. If I move my cursor around the screen, it will change when I scroll over a clickable link that I know is on QC. Make sense? ha

So if I access QC from google, it will display the google page, but if I move the cursor around the top of the screen where the QC drop downs are it will change from the arrow to the pointing finger.

I don't think that if the nut loosened up on the carb it would hold it open, it would actually make it slack and less apt to throttle response. The spring in the carb will pull the cable back when in idle.

I would definitely rejet if it is still stock (notoriously bad stock jetting), I'm about 95% sure it is running lean now. Average setting for these is usually around 165 main 45 pilot and 2.5 turns out on the fuel screw, that will get you in the ballpark.

I'd just try to google a download for the trx manual, I'm sure they are out there.

Turns it in to the yz450f cam timing giving it more power in the mid & upper range. Just gives the motor a little more pop.

Some poeple think the motor doesn't run as hot after doing it either, but I'm not sure if there is any truth to that or not.

You know red heads are crazy right?

Rotate the exhaust cam 1 tooth clockwise. Basically turns the motor in to the dirt bike engine. I should have checked my valves when I had it all apart, so it's a perfect time to check them when this mod is done.

and of course, the YFZ450

I like the kind of riding that goes on when the lights go off. Either that or anything fast where I am in constant fear for my life.

Depends on what kind of power you want. Do the 'cam mod' it's free. Pop the air box lid off if you already haven't. Those and the pipe and filter you put on will give you decent power.

There are tons of other things depending on what you want, like different sprockets, FCI air intake, big bores, etc.

ha ha Correct! Actually I'm just going to FedEx it all to CO

Dyna programmable. I've heard a lot of bad things about the black rev boxes made my Procom (the ones every company puts their own sticker on).

..it comes from a lot of me breaking stuff then having to try and fix it. Also why the quad is in 1,000 pieces right now.

Put a bigger main jet it. What size jets did the kit come with(I'm not familiar with moose brand jets)? The 48p sounds like a normal size, but I'm not sure about main. I used a gytr jet kit that came with my pipe and use main jets between 165-170 and pilots 45 or 48. If you'r screw is out 3 or more turns, you need a bigger jet.

What Bot said. Lube your cables, and check they are not getting caught up anywhere and the slack is set correctly. 450s idle high anyway, so it could be normal..hard to tell not hearing it though. Probably needs rejetted, especially if it's still stock settings.

jetting theory

manual

Do you need a diagram for jetting? Just loosen the clamps on the boots, spin it so you can reach the 17mm cover on the bottom, remove that and you will see your main and pilot jets. Take them out and put bigger ones in (i.e. 165 main 45 pilot or whatever size works best). You should also pop the plug blocking your mixture screw and put an aftermarket one in

Competition. They didn't wanted Honda to be known as the 'R' quad (i.e. THE race quad).

Personally, I like the regular YFZ more. I'm just not a big fan of FI. We'll see how the new YFZ R makes out though, even though it will be more rider skill then quad.

Check stuff like Craigslist or yfzcentral's 'for sale, complete quads' section. With the economy in shambles, a lot of people have no choice but to dump off their quad. The yfz site has a lot that people get rid of each year, or when they get picked up by sponsors and don't have to buy anything themselves (lucky b@stards!).

Anyway, good luck and let us know how you make out man.

We have to have plates here in PA as well, but mine pretty much stays in the back of my truck. Our off road governing body (DCNR) misappropriates funds on a colossal scale. I do not plan on displaying my plate again or renewing registration simply to have my money fall in to an account that does not promote or help out sport.

As far as the license, that definitely needs repealed. I'm 29 and haven't had a license since 2004, does that mean I wouldn't be able to ride a quad in the dirt?! When families stop coming because the kids can't ride, someone will be missing that tourist $$$.

I never noticed that. ?? But will have to check that out. Stealing the R. Pfft. ha ha

I'm starting to like the black anyway, but I even know a Honda rider who does to. hmmmm

I would love to meet up with you at some point Hooligan. I have been known to do some pretty big road trips. My last one was 3600 miles round trip.

Cool, come pick me up!

Oh man, I got one of his buried in the trees somewhere!

You'll have to put one up with the new tires on.

oh man if my quad wasn't in 23409325302 pieces...I'd totally be there. Post pictures!!!!!!!

Duct tape.

I always have a good time when we get together and ride, and it is a mostly superb group of people.

..or at least cleaning the filter that's in there.

I didn't even know you could buy gas in zimbabwe.

We were talking about replacing the piston every 20 hours, not the rings every 30. And if you are a YFZ expert, you know a compression test will not be very accurate. Obviously if you change the oil after every ride you will prevent some miniscule wear, but you will also get a longer life out of a machine if you rebuild it after every ride...both of which are not plausible or in any way necessary.

Anyway, your 04 probably did need replaced after 30 hours if you didn't do any kind of oil modification, but I'm sure you have another theory about that.

I guarantee you will not smoke me, and that's no BS, quit giving out false information.

Are you trying to find out what year it was manufactured or like the VIN #? Here is something random about VINs I came across (thanks Google). The VIN should be on the left side of your frame (shifter side). Not positive about the Timberwolf, but a few of my Yammys had it right on the bottom of the frame.

if you had to replace the piston ever so often, would it be worth even having one?

No. ha ha That is a myth obviously. If they need replaced every 20 hours, and break in time is 20 hours, you would be perpetually replacing freshly broken in pistons.
