I've seen a few of 'em runnin in the dunes. I recall an article on one in Sandasation Magazine about 6 years ago, I think it was a Lager built with white plastic. Anybody know what it takes to build one or if anybody builds a conversion kit?

What year CR500 is the best to use?
What fork do you use?

Any other tips would be appreciated.

There one in the trader for sale, it looks real nice

Most of the motors from like 86 on are the same. Watch out for the older bikes the waterpump housing corrodes away to nothing. If there are white rocks in the radiator, its the waterpump housing going away. It happens on like everyone. Other than that, they are pretty much the same. 88-90 were mean 90-02 were damn good motors bone stock. Seems like a lot of work.

The Bomb has a 250R four trax with a 500 in it. He might be a good one to get some pointers from. I was told that the motors were slightly de-tuned as the production run went on through the years cause the motors were to powerfull. They were hurting people, the bike wouldn't hook up, etc. If you plan on porting the bike or raising compression, I wouldn't worry about it but if you are going with a stock motor, you might want an earlier motor. Not sure how they were de-tuned.

I would also appreciate any info on this as well. I have a friend that wants to get a 86 250R ATC and throw a CR500 motor in it cause he can't hang with me...

Thanks.

You will need one long beefy swing arm, the header might need to be modded to fit same with the muffler, electrical, suspension will need to be dialed for your weight and swing arm, alot of fabrication will be done

Anyone know of a bike like this that is for sale?

I believe The Bomb is selling his. He is in the sandrail forum. Has a V8 rail being built. Do a search and PM him.

there is a guy with a cr500 85 atc with white plastics that hangs out in the atvconnection chat room sometimes. last time i talked to him he was still trying to sell it. i think he usually rides around the buttercup area.

Ive seen that guys ATC 500 run. it runs real good, but he says it vibrates the sh!t outta him though.. Maybe you can get it done, and i get mine done(next dune season), then lose to my 420 cc tri z lololol honda.. pffff.

CR 500, more like Cee ya 420...

01,

I built a TRX500R from the ground up, 86 TRX salvage yard frame, 87 CR500 salvage yard engine, bike is entirely gone through. over 10,500 invested. Runs like a raped ape on steroid rage! I ended up with having to replace all case halves, rebuild crank, new bearingsseals, shift forks, Hinson clutch, hydraulic clutch-too darn hard too pull cable, sent head to Trinity for port/polish/bore, about 75hp, with 50/50 gas, running boseyn RAD reed cage, 39 mm Keihn carb.

Back to install-Larger is an ARSEHOLE, called them before I started this project 4 years ago-they didn't sell the conversion kit anymore, they wouldn't even sell me the plans, it toke over 12 phone calls before they returned my calls, and then they told me tough shiat! Screw them. I mounted the 500 motor on the swing arm pivot bolt-slide it all the way to the left and the sprockets will line up perfect. Then use on of the stock collars in the 500 motor mount and it is the perfevt length spacer for the right side.

Now fab front motor mounts, reinforce everywhere on the frame you might think it needs it! Yes it vibrates like crazy, but once you start riding the adreniline kicks in and you forget all about that! Some guys have mounted the motor in rubber or poly bushings, I read about that too late....it might help. Spray bomb the frame until you ride it for a season, so if it has weak areas you can correct it without a big hassel. The pipe is another ordeal, I used a FMF CR500 pipe for a 98 model, CR racing wanted $500 dollars for a custom pipe...right!! All I did was modify/replace the 2 small down tubes by the radiator, and some slight mod to the exhaust can...no problem....alot cheaper!!

My quad is quite unique, RPM rear end parts from a ATC250R, Bomardier radiator (1/3 the price/twice the size..very cooool!), 400EX plastic, tons of new TRX250r chassis parts, billet this and that, cromoly swingarm/a-arms/steering stem. I only have about 6 hours on the bike, but the more I ride it, the more I'am thinking about keeping it. I've left modify Banshee's in the dust. The quad really shines in the rough stuff..set up like a desert runner. It's hard to drag because of the wheelie factor....did I mention wheelie in the first 4 gears at will!

One last thing....it is a typical CR500...a biatch to start, I'm still learning. Definitely not a girlie's man's bike!! A lot of work...maybe worth it. I'll be at Dumont for the clean-up if you want to check it out. I'll be camped with the v8Rail gang, big red International medium duty semi truck. E-mail me, I can send you more pics/info. I'm starting to get my grove on the bike, and I plan on kicking some major ARSE on this trip. Stop by.


THE BOMB

01,


Almost forgot, I wouldn't put that motor in a ATC, that's why I parted out my ATC and went TRX. I like alot of suspension and fast over rough stuff, aTC will beat you to death!!


Roostking, I'll smoke that hillshooter anytime in the dunes, you keep that trailer poser at comp where it belongs!!!


THE BOMB

Oh, dont fret, itll go back in the banshee frame in about 20 minutes. so i got your number at comp and the dunes.. we all know a stroker banshee motor is much easier to ride than a single cylinder bike.. I get 73 hp all day long, without replacing the motor twice over, and it dont vibrate like a b!tch to boot! Got pipe???

'01, go to Go here, track down Kasey Kasye has an ATC 500 and imsure hell be more than happy to help!

roostKIng...

RK is right Kasey is the guy when it comes to cr500ATCs.. I think the frame has to modded in some way to get it to fit..
Heres his.

Thank you Toy Collector, thank you veeeerrryyy muccch!! I'll be at Dumont over clean-up weekend (3/13), if Roost King can trailer that low rider out there. See if he can take the whoops taped in fifth gear. Bring that Banshee chassie also. Just remember it's clean-up weekend, so you'll have to help. We'll be camped at the announcing area for the door prizes. Loser buys drinks.


THE BOMB

My trike is still under construction, and the 417 stroker motor is down for some freshening..

Halloween? Thanks giving?? Im good then!
