:thumbsup:

One of the last things I would do is the oring mod. Can't believe anyone would do such a hack mod. Do you think Bubba had this done on his 450 last year? Don't think so.:cheers::thumbsup:


I did the oring mod about 2 days ago and man what a difference. But still i need to rejet no mater what.

But i have been looking on ebay for the 06 cdi and i cant find nothing but i guess im going to have to wait.

I'm either looking to get the DRD or the fmf 4.1 with the megabomb header.

I was also looking on yoshis site but is the Rs2 a good pipe or should i just stick with drd and fmf.

I'm also thinking about a rekluse but i only ridden a 250f with one, and i thought it was pretty neat but i kept pulling in my clutch going around a tight bend. About the rekluse, can you adjust it like where you want it to engage? I heard of people saying that they can make it like "slip" itself when ever coming out of a bend?

That's why I bought 4 06cdi's on eBay before this mod got real popular.
As far as the Rekluse, I feel it is a must have in any type of riding. They are that good.
I don't care if the oring helped, it still not the right way to do it. It's a hack job way.

I haven't tried either the Dr.D or FMF exhaust on a 06-09 YZ450f. I chose to purchase a LeoVince complete stainless system. I chose the LeoVince for their built quality, sound levels, and willingness to stand behind their products (They have also really stepped up and supported local-national racing organizations). It adds power everywhere, and fills in the low end the stock pipe lost, but is very smooth and linear. It may not be the most powerful system, but I've yet to see a pipe with better built quality and durability (Akrapovic is comparable but much more expensive). I've never seen a LeoVince exhaust fall apart, but can't say the same for either FMF or Dr.D.

You want to send me a 06 cdi? :thumbsup:

Im just kidding but im just going to keep looking. Now if i do this mod will it really affect the reliability of my bike?

Now people have told me to go MRD, are they like the same quality as fmf? But only reason i ask is because i heard that their prices were pretty good

The CDI swap WILL NOT affect the reliability of your bike what-so-ever. And like I said before, any aftermarket system will make a very noticeable power increase, trying to figure out which is best is more a matter of personal preference.

I haven't had a MRD pipe, but I would guess that their build quality might be better than FMF ?

As far as the Rekluse goes, my buddy has one and although I think they're somewhat interesting I always ask if he's running his "spode" (noob, flake, sissy etc. etc) clutch. This is just my personal opinion, but I think an automatic clutch is something that should be saved for the 50's that my 4 & 5 year old ride. What's next, traction control, or maybe a sensor that cuts the throttle if the front end comes up ?:thumbsup: There are a lot of people that like them though...

The Rekluse definitely has its place. Owning one, I doubt I'd be interested in it for MX or any other kind of track riding, but for the tighter, slower, more challenging sections that get tossed into a lot of the desert races, it really helps.

As far as all that other stuff, I don't know if you realize it, but there are actually a lot of traction control systems in place in automotive road racing, and some of the World's best drivers use them. (a ZO6/ZR1 Corvette is almost undrivable without it turned on to the first level) 4 wheel ABS systems are nearly universal in many forms of racing, too. Turning your nose up at such stuff is like being a fighter pilot and saying you don't want anything to do with radar guided missiles or self leading gun sights.

Well said Gray. I would just like to add that my brother used a Rekluse for motocross and loved it. Helps in many ways there also.
And to the guy saying it is for old people and young kids is just plain being ignorant and closed minded and once again making a judgement with zero experience. I just don't understand that point of view!

Sweet thanks to all the info guys!!!!!! I have to finish paying my bike off but that won't be long.

But I'm going to look into the rekluse, exhaust and 06 cdi.

Would you guys recomend carbon fiber for a skid plate or aluminum?

There's so many things I want to get but I only have some much cash at a time. I think I'm going to get the exhaust and cdi first then down the road the rekluse. Hahahaha

Any other ideas?

Grey,

Are you a fighter pilot by any chance? Just wondering since this is a great quote!

Me turning my nose up at an auto-clutch won't get me killed, can't say the same about ignoring radar technology in a fighter jet.

I am very familiar with traction control, I started road-racing before I'd ever owned a dirt bike and it's becoming more and more mainstream. What was new when I last road-raced was slipper clutches, they worked great but at the same time they take something away from the art of riding. You need less skill to go as fast, plain and simply.

And to the guy saying it is for old people and young kids is just plain being ignorant and closed minded and once again making a judgement with zero experience. I just don't understand that point of view!


Whoa whoa, hang on there. #1) As I stated, that is my personal opinion - like it or don't, it makes no difference to me and should be the same for you. I DID NOT say they don't have their place, I don't ride trails - I ride MX. They might be the best thing since sliced bread in the trails, and that's great. But, IMO part of the skill of riding a dirt bike on a track requires the knowledge/appropriate use of the clutch, if you automate that.. well like I said, why not go with a sensor/system to keep the front end down ? And yes I've had experience with riding a Rekluse equipped bike, don't remember saying I didn't have any.. but none the less.

There's no need to get upset about this, there great for some people... just not me :thumbsup:

But I ride woods and I'm going to be racing harescrambles, and I need more low end snap and more mid range. The top is good but I mainly need more low and mid.

Alex


Ok, don't take this the wrong way but I have a question.

1) Have you ever raced a harescramble? Have you ever seen a harescramble track?

I race harescrambles with an 08 YZ450f. THE LAST THING I NEED MORE LOW END! I am actually considering going with a different bike just because of that. It's great in the starts and wide open stuff but anything tight or sloppy it is the worst bike to be on. That back tire wants to break loose by just breathing on the throttle. Now I will admit I am not a pro rider or anything but even everyone I talked to says the same thing. Harescrambles are not trail rides, there is some nasty tight stuff in them.

I have done a ton of work to mine, in fact it's in the shop getting ready for the next race now. I don't know what flywheel comes in the 09 but by far the best thing I did to my bike is buy the heaviest flywheel they make for it. It was night and day difference. You can't compare a MX race to a harescramble. 2 totally different animals.

If you want to know what I did to mine send me a pm. Basically if you want to run a scramble you need to 1) get a new set of tires, the stock ones won't work, 2) cut you handle bars down, trust me 3) heavier flywheel(depending on stock weight) 4) Bark busters, no doubt 5)skid plate, if you value your engine.

The 450's are allot to handle in the woods. I'm 6'2" 215 and it tires me out.

Once I get the bike back, this time, I am going to decide if I am going to keep it. If I am it will get a rekluse. Don't listen to the guys that say they are sissy clutches. All and I mean all the top 25 GNCC pro's use one. Argue with that? Pa isn't dessert racing and this ain't no mx track.

And you may have the wrong idea about desert racing if you assume it's all wide open spaces, put it in fifth and pin it stuff. Lots of tight spots, rocky climbs, etc., where the Rekluse really helps you get away with that high first gear.

I have seen a harescrambl but i never raced on one. But i do ride a lot of singletrack and stuff. But i just got the bike about 3 weeks ago, and im more than happy for what i have.

But i just want to try a race, just to see how i do, but i got to get the bike payed off and i want to get some skids and some other protective stuff for it, and i still need bark busters!:thumbsup:

Also i saw there was 2 rekluses, a z-start pro and a Exp? Now would the woods guys use the z-start? Or can can I use the exp?

Also im running engine ice in it as well.

They've never been a problem for me, nor for anyone else I know. The plastic free standing ones are worthless except as roost deflectors.
