Dune Quad

I ride 100% sand. Some of the things I’m sure would transfer over to other types of riding. But as I said before this quad was built for the sand and how I ride it.

This quad came to where it is in a back handed manner. I had a long standing order with my dealer for the new R sight unseen. Most of you all know how many times the rumors of a new R were in the various magazines, aftermarket or secret testers… I was about to pull the trigger on the Yammie but just couldn’t bring myself to do it. Yeah I’m pretty prejudiced when it comes to Honda. I’ve owned an ’86 R since picking it up off my dealer’s floor in November of ’86. My wife and daughters all have 400ex’s. I just know Honda’s and am comfortable with them. I’ve had Suzuki’s, Yamaha’s and yes I was one of the idiots that thought Cannondale could make it. I just always came back to the old R and Honda.

When I picked up the new R, I was under whelmed with it. Sure it was better than the EX but it wasn’t near my old R so I thought I would be selling it quickly. The kick start, the rear end, lack of oh sheet! speed… But the more I rode it the more I began to appreciate it. It really felt like it had the potential to be a really capable quad. I told everyone that I was going to leave it stock but for the HRC kit, yeah right! One thing lead to another and it just seemed to get better and better. I decided that for my riding I wanted to go wider and improve the suspension. Since I was doing the arms I might as well pc the frame and since I was doing that I should really clean up all the factory welds. At the time there wasn’t really anything for the motor besides the HRC kit, FCR carb, and aftermarket pipe(s). So for the time being that was pretty much it motor wise.

After the new suspension was done I really fell for the 450. The first time out to Pismo I was hooked the thing just did so much so well and so easily! I headed for St. Anthony’s and rode the crap out of it. The old r sat in the trailer the entire trip. The 4stroke was just so easy to ride. I could ride longer and harder with the new R. For all around duning it was great and really didn’t need anything more. At Sand Mtn. Nevada the need for more power reared it’s seductive head. Sand Mtn. Has some decent riding areas but it’s really all about the hill! The 450 just couldn’t hang with the semi fast guy’s there or my old R. I needed more power! A 13:1 piston and some head work along with a crf ignition system. Then a 480 big bore. Various pipes have been tried and now another motor was purchased to sacrifice to the hp gods. More on that later…

I have quads that are faster up the hill or in a straight line. Some have more brute HP. But what I’ve done to mine so far has made it into the best all around performance quad I’ve ever ridden or owned.

Very Nice.
I can't wait to see it in person.
I also can't wait to hear about the TBA engine
Thanks for sharing, and thanks for the help!

Oldsandman .. that R is simply a work of art. I fell in love with it at first site Congrats on the sick ride


BTW .. a couple pics weren't working .. I fixed the links

St. Anthony's:

That's 450R bling at it's finest. With all that polish and chrome, everyone in your group must have tinted googles to be able to ride with you.

Outstanding quad OSM!

Thanks! I couldn't figure why they wouldn't work....this stuff is over my head!

The famous pic! There is it! (My old desktop wallpaper)




-The Kid-

That used to by desktop wallpaper as well. That is by far, the best R that I have ever seen. It just looks so good.

I too fell in love at first sight It is a work of art.

Beautiful ride. Represent the West Coast. Anytime you head to Pismo post it here and I'll meet up with you. Sweet bike man.

He won't be hard to find! He'll be the quad riding around that looks like a moving sun from all that bling

It looks great OSM, thanks for telling us your opinions on the 250r/450r differences.

Looks awesome man, i love it, one question, could you possibly write us wat you think about the magura hyd clutch and ease of instalation in the product review, im intereted, but once again awesome quad.


BTW.. I have a Project Underway :D


Ryan

Very Nice!!!!!!!!!!

Very nice, so whats up with switching the esr exhaust to sparks, which produces more power, in low-mid-top ?

Thanks everyone! It's pretty funny where the st. a's picture has turned up. It's amazing how far these forums reach.

...i cant say anything that hasnt already been said. except i love the trim job on the front fenders!

Thanks, hopefully the motor goes together without a problem!




I'll try to let you know next time I'm headed down there. Right now my daughter is on spring break. Once she heads back down there to school I'll head that way.




I like the hyd. clutch, I've had on on the old r for a few years and on street bikes for a long time. I've heard some gncc racers say they don't like them but personally I've only had one problem over the years. The magura line doesn't like anything hot touching it! It melted through very quickly on my old r's pipe. The best fix is sleeving or changing to braided line and being careful routing the line. I'll see if one of the mods will let me review it.




I'm currently running the ESR. The sparks was pretty much the only game in town when I got my 450. Their is nothing wrong with either pipe both are decent pieces. I personaly found the sparks to be annoyingly loud. It also didn't have a sparky which can be an issue. I have both the esr "race core" and the quite usfs sparky pipe. I haven't dyno'ed them, I going to. As for the butt dyno the esr and sparks open felt close on top with the esr pulling harder bottom to mid. The esr plugged gives up a little to them both but I tend to use it the most. In Oregon and California noise is an issue and I just prefer to let the LEO's deal with other people. The fact of the matter noise will be an issue everywhere soon. I'm just trying to do my part to keep areas open.

Feel free to do a review on the magura clutch in the review section OSM, i'm sure a lot of people would like to see it! :D

hey OSM wernt you going to put the PC on it? just wondering. ive said it befor and ill say it again, that qiad is bada$$!!!

As soon as I get the other motor done I'll probably try some more pipes. The pc will probably be one. I've been looking forward to the stealth version coming out and seeing some reports on that.

In case you are interested:

Stealth Charger Thread

Kam is the only one with a report so far. There should be more in there and in the pinned thread in the Engine Forum over the next couple weeks ...

Very nice OSM.. And just think guy's.. I've seen this quad up close and personal. Seeing it in person is way better!! Picture's never seem to do justice!! :D

Rico

I added some things to the r. I put a temp gauge on it. You can see it peaking out, I think I'll trim the plastic a little. We'll see how hot we can get!

I also added a gps mount from IMS.

the stealth version is great. its real quite. it sounds the same as the regular just without the loudness in high rpms. it does take a smaller jet, but i couldnt feel a difference between the two. and dan didnt seem to lose anymore in the drag catagory.

Where did you find that temp guage OSM? I used to see them around some but I haven't seen one for a while.

Thanks man! Your's is looking pretty good for an MX'er :D




ESR has temp gauges. I have one on my 330 and thought why not on the 450.

Thanks!

OSM, that subframe is... amazing. Very very good job on that thing. I always wondered what the Tag silver/black pad would look like, guess now I'm even more happy I ordered it!

OSM-

That is the best looking 450 by far.....ever. Keep it up!! I think your shop is the ultimate "dude heaven." I keep joking with my wife that I'm going to build a shop so I can get some "dude" time after our daughter is born in June, I'll be outnumbered 3 to 1 then. Seroiusly though, what a work of art!!!

Thanks! I have to have my sanctuary! I was outnumbered 3-1 also but all in all it was great! You sure miss them when they're gone.

Whats better OSM's quad or Angelina?
Tough to call that one.
I have 4 sisters, and now a wife with 3 sisters. The garage is a MUST!

ohh angelina!

Angelina is so hot! But I'm sure she can be just as much a pita like all women can be! Except of course my daughters and wife who are perfect! Ok she stopped reading....At least the quad doesn't talk back and is always ready to go! :D

Well after last weeks testing the exhaust left standing was:

Man, that thing looks great, I like the black can, its stealth looking.
Do you think you will have a good Oregon pipe now?
If I am not mistaken, those are 21" tires, that thing was smoking up the hills huh? :D
That whole thing looks so damn nice, thanks for another wallpaper!

This pipe will work probably anywhere! I had plenty of comments on the sound too! All very positive with lots of "it sounds throaty but not loud". Lots of what is it ?'s too. Especialy after handing plenty of a@# whoopings with my stock bore/stroke motor! It really surprised me what I was beating. The pc pulled so well in the middle through top, it really worked well on the hill!
The tires are 21' 7 paddle and I was running 13/39 gearing. The CRF ignition was finally dialed in too! All in all it is a screamer and I'm done with this one. Now it's on to a bigger motor!

The ignition is nice huh?
Bigger things to come!

The pipe look awesome with the black plastics for sure! :)

pimpin!!! :D

got any action shots?

ha! pretty sly there osm!!!

Oh yeah! Really like the ignition, well worth the work. Hopefully the next motor will hurry up and come together.




Thanks for getting the stuff to me so quickly!




I'm the one who takes all the pictures so I never get any of me!




Gotta be a little sly when you're outnumbered by women! Just a self-preservation thing!

Is this not what the old 450r use to look like hehe. Haven't seen you around in probably over a year now OSM. This guy builds some mean quads

That was the before! It was about a week old then! I don't remember posting that picture. :D

Still one of the best looking quads I have ever seen!!!!!!!!!

that is exactly the tire and gearing setup i ordered for booster for silver lake!

i'm guessing it works pretty good for yours??!!

my wife was walking by when i was checking out the pic of your machine and she said "DAMN!"

add one more quad to the list i'm jeaolus of!

It works really well going up the hill! Really made a lot of people notice. I tried a few combinations that week and that was the winner.
Thank you and your wife for the compliment!

Well here is the next step in the evolution of my R. I really don’t know what to call it now besides an R, it truly is one now! My second engine has now become a 510cc fire-breathing monster! I’ve only had it on the dirt so far but it pulls like a freight train! It still is very tractable and isn’t peaky just a very linear but brutal acceleration. It still has the 4-stroke feel pulling all through the rpm range. It flat out destroyed my ESR330Rpv. I can’t wait to sling some sand with this one!

I’m extremely happy with the motor and can’t recommend Steve Polk’s Pinit Motorsports enough. Pinit deals in “package” builds. He wants to build complete engines not just bolt on some parts or port heads. Steve was willing to share information and his experience with the crf, trx and yfz. All in all it’s a very informative experience spending time with him. We learned a lot from this build that I’m sure will add greatly to the next one. Considerable time was spent on his dyno tweaking the motor. Everything from pipes, carbs, ignitions, airbox to different length intake boots. The time Steve spent dialing this in was amazing and like watching a master at work.

Steve performs all motor work, which in my opinion is a very good thing. Think of how many top builders do it all themselves. Usually you’re paying for some guys name and a nameless assembler is doing the work. Basically cookie cutter engines unless you’re a “name”, pro or big account. Having one person accountable and standing behind his work has really become rare these days.

This build is not cheap…I’m sure some will question the cost but it was an exercise in giving a great builder quality components and letting him work.

I’d also like to thank jjk450r for his help it was greatly appreciated. I owe you!
