Well after at least a year of riding different bikes models and just about everything under the sun I bought a bike. The current state of my 03 turned dire. It's the begging of the racing season and I cannot keep up with the repairs from a moral stand point anymore and the poor old girl is so loose sometimes I wondered If the wheels where falling off.


So after being frustrated as hell for quite sometime I was looking around on craiglist and I found a bike that called to me. I cannot quite say what it was, It could be I was thinking about how I wanted to take a hammer to my 03 and how I was thinking how I don't know what to buy and then it hit me, Keep it simple stupid, Stay YAMAHA YZ it's what you know and like. So I called the guy and inquired about hours and what not and it all sounded good and I was on my way. Upon meeting the guy it was clear he was a 3 big weekend a year rider and after a check over the bike I was assured it was most likely under 40hrs without a problem. He was asking 3500 for it and I got him down to 3200 without killing him. To be honest now that I have it home and have tore it down I ALMOST fell like sending the guy another hundred bucks. On my way home I called my suspension tuner and lined up a meeting for tomorrow morning. In pulling all the suspenders off I realized there was no tool marks on any of the bolts on the front end, even the axle. Upon pulling the rear shock I found the top and bottom shock bolts have basically no wear on them where the shock rotates on them. Over all the bike has some scratches from some tip overs and dumps, but mechanical it is as if the bike has about 10 hours on it. To say the least I'm very, very happy. So much so I thought I would share.


Specs as far as mods, current


FMF Mega bomb Ti header.

FMF 4.1rct Ti muffler along with ti mid pipe.

Both in very close to new condition.


FMF Jet kit.

I'm not much for jet kits and I think I will put it back to stock. As my 03 with FMF set up runs great with stock jetting except a one size larger pilot. 


Future mods,


Reckluse clutch I want to investigate pulling the one out of my 03


Stabilizer Gpr v4


Desert tank


Skid plate


New flex bars, the ones on my 03 are as wore out as the rest of the bike.


06 clutch mod, need to investigate how that will pan out with reckluse.


18" rear wheel, I just found out that the 09 has a larger axle so maybe have to lace one up.


Any advice is greatly appreciated as far as how to desert sled this bad boy out.1512431_10202979922409127_715516828_n.jp1508089_10202979922889139_1945950883_n.j1513315_10202979923249148_1600674689_n.j

Good deal! Stoked for you.

Chain and steel sprocket set (if stock), nylon chain guide, case saver and al shark fin. Radiator cap and waterless coolant if you think you might get stuck. If you decidet to buy lower or rear offset pegs, I'm in need of some 5HD/stock 450 pegs for my 250.

Which Rekluse does your '03 have in it? It should work either way, just curious.

The 03 has the Z-star pro in it. I was looking on ebay last night and found a new in box Core EXP 2.0 for the 09, snagged it for under 400 bucks . So now I guess I can form an opinion on which I like better and sell the other.


I have 2 question, Will my Barnett clutch basket out of my 03 work in the 09? The current basket is mint but my buddy needs one and I would rather run the Barnett. I see on their web site they list the 03 different from the 04-09+?


As far as the 06 clutch mod, since both recluse units come with new pressure plates and springs, do I just need the actuating arm, fibers, and steels off the 06?

The two Rekluse units are interchangeable between the two bikes.  You'll like the Z-Start better than the EXP.


The basket fits either bike, but the primary gear set was changed in '05, and your older gears don't match up with those in the '09.  You would need to remove the basket from the '03 gear and install it on the '09.

Congrats! I just picked a low hour 09 too. Rode it for the first time at Monster Mountain on Monday and I absolutely love it! Happy to be back on a 4 stroke for sure.

I have only put about 45 seconds on mine so far. This is how she sits as of now. I just got a large load of parts in the mail today that I need to put on. I also get my suspension back tomorrow as well if things go as planed. l hope to log some good desert miles this weekend. I wanted to make the first round of the National Hare and hound series but I'm going to hold off and learn the bike a bit first, I THINK lol. O yeah I got the z-star pro from my 03 in there no problem, thanks Greyracer. We are throwing the core exp 2.0 in my buddies 08 with the barnett basket saturday and he is racing sunday. Fun Fun

Is that the stock rear tire?

  • f150jokerstyle

Posted January 23, 2014 - 08:32 AM


I don't think so because it's a MX 71. I'm not positive but I believe the front tire is the original one though, it is a Bridgestone.

I found out even when trying to swap gears from the 09 to the 03 basket it does not work. The 03 gear is a 1 piece design that has an outer gear/inner gear made out of one chunk of steel. The 09 has a 2 piece gear design, It has the inner pressed into the basket(with splines) and the outer gear riveted to the back of the basket with the pillows/bushings.


First image is of the 03 set up.


Here is the 09 style,

Well last weekend I made it out and got some miles on my ride. I guess the first question is, is it an improvement over my old ride? Short answer is absolutely. Suspension is wildly better than my 03. I hit some stuff at speed I thought was going to end my week let alone day and it took it without any complaints. Chassis and ergonomics is a large improvement. Stability at speed is better and the steering is much more precise. At high speed the handle bar feeling threw whoops was a tad nervous but the stabilizer should fix that up. To be honest the bike is better everywhere with the exception of maybe one department, the power, but the jury is still in deliberation on this one. I'm not sure if it is just that the power is delivered so much more smoothly over the rpm range than my old bike. Or possibly the fact this is a true 450 with 12.3:1 compression, where as my old bike is a 470 with a 13:1 piston in it. But the bike feels very weak on top to me. The reason I say I'm still not convinced this is the case is I ran it in the desert with stock gearing 13-49 and the shifting was quite quick and may have given me the impression of a flat top end due to it getting there so fast. My old 03 I was running 15-47 and it just seemed the bike pulled hard until it would start surging off the limiter at around 90mph. This 09 with the stock gearing I never experienced that. I ran it wide open for some time and never found that limiter bounce. I have since installed new gearing on the 09, 14-47 and I'm looking forward to testing again this coming weekend. I do think my perceived lack of top end was due to the gearing but I will know soon enough.


A few more parts added since last ride and up date are.


New sprockets, Outlaw racing steel units. Gearing 14-47


New chain, Rk exw. A little note about this chain, It is HUGE!


GYTR skid plate


Scotts stabiler mount. I opted for this over the GPR I wanted to try out for a few rasons.


#1 I already had one and liked the way it worked, but not how it mounted.

#2 The GPR required you to run the bars in the #1 bar position(closest to the rider) and I'm 6'2 and I like my bars further out.

#3 The scotts mount let me have the bars in the 3rd position.

#4 Since I already had the stabilizer it saved me about 4 or 5 hundred bucks.


The last bits I want to install is a 18" rim and new tires and thats about it.

A couple updates:


The 14-47 gearing was stupid tall, I don't know what I was thinking. Now at 13-47 and it's perfect.


The gearing did help the perceived power thing I was talking about. The bike absolutely rips.


When I installed the stabilizer I somehow over tightened the steering stem nut from Scotts and I ruined my steering bearings. They felt fine after I had it adjusted but after leaving the bike still for about 20 minuets the steering would lock up then feel smooth again. It was quite weird to say the least. I'm not sure from me over tightening them, maybe crushed the cages some, or there is the fact that there was some sings of water contamination from a pressure washer from previous owner, but new bearing and races fixed it right up. Also it might be worth noting as well this 09 had the old style upper bearing in it.


The use of the stabilizer has enabled me to take another link out of the chain and move the rear wheel forward at least .5" or a bit more and also move the forks up in the clamps around 3-5mm up from the line. I also added the Pro Taper Windham bend bars. I cannot say if one move did more than the other but it is stupid how well this bike now turns. 


I also added the GYTR FFW this helped the bike from flaming out even with the Rekluse and helped with power delivery in super choppy/rocky sections. I did not think it would be that worth wild with the Rekluse but they really compliment each other.


For the first time ever I tried some Kenda Washougal sticky tires. To be honest I have never really heard many good things about Kenda tires but a buddy had a line on a good deal on some so I gave them a go. I honestly feel stupid for not giving them a chance sooner. I only have one good ride on them so far but I actually like them more so far than the normal Dunlop's I run, D952,mx71, AT81rc. I cannot believe the traction that the rear produces in the terrain I have ridden so far. In the sand the only thing I would chose over this tire is a paddle tire. I went with the 120/90/19 and the 80/100/21


Last but not least I bought a Scotts oil filter. I'v herd good things so we will see.
