500R ATC whos got one

[Bozman505]

I was looking to see if any one has a 500r if so who made it, how does it run, how much you got into it, ect.

[84250r]

That would be KASEY.

You should be able to get him thorugh pm.

[ScottZJ]

Yes sir Richard has one and I get to ride it soon! Wooo Hoooo :-D

[hondatrikesrule22]

:?: What is a 500r? I know it is a 250r with a bigger motor in it, but what motor?

[ATC crazy]

:?: What is a 500r? I know it is a 250r with a bigger motor in it, but what motor?

CR500R Dirtbike motor :twisted:

[CHAINSAW]

There are also some 250R bottom ends with 400cc Pilot jugs on them, and a hybrid with a 500cc Polaris jug nicknamed the Polanda... The few I have seen of these are in quads.. never seen one of these motors in a trike yet.

[200x Basket]

i built one. it was fun but to fast for anything but the dunes.

[Red Rider]

There's another hybrid also. It uses a 250R bottom end, who's cases have been machined to accept a CR500R cylinder. I can't remember the name of the company that does it, but it'll come to me eventually.

[CHAINSAW]

MAC racing.. I cant find their website though... they do that mod.. for a measly $4500 bucks.

[KASEY]

$4500,,,,,,,,, thats almost twice what i have in my whole trike!!! lol

[TRI-Zbrian]

it would be kind of cool to put a CR500 engine in a tri z i know it would be a hybrid but it would still be cool i think :twisted:

[CHAINSAW]

$4500,,,,,,,,, thats almost twice what i have in my whole trike!!! lol

It might of not been that much.. but I remember it being some ungodly amount that I couldnt afford..

maybe it was more like 2500, but I know they did not provide anything, except the machine work.. you sent them your case halves and a jug./

[KASEY]

right now i have around $2400 in the 500 that includes a $800 total engine and tranny rebuild ,, keep in mine i do all my own work everything that was done to this machine was done by me,,,paint,welding fabrication, tuning,polishing, building,rebuilding, fitting and lotsa refitting i had a 4" over stock swingarm on it ,,it was to short so i streched a stock arm to 6" over which i like so far,, so if you add in all my time on this project which is alot,,,, then you don't love the sport like i do!!!!!

[sandrooster]

Hey Kasey,
If you truely love the sport, you would have a seat cover that matches the motor on your 500. :-D

[ScottZJ]

Neah he wants to be stealth! LOL :rolleyes:

[KASEY]

yeah rooster that would work,,,, then nobody would line up with me ,,,, they wouldn't even take a chance that they might get beat in front of their fellow riders!! ,,,, right now they can't line up fast enough to beat an old 3wheeler,,, and i like it that way .... besides there are hunderds of big bore 250r's out there!!! and they don't run around with signs flashing sayin they have a big bore,,,, would you line up with me if you knew i was going to blow your fenders off????? :D :D :D :D :D

[sandrooster]

Yes, I would line up knowing I will get blown away by your 500.
At least to see the difference.

Thats how I found out that my 85R is faster than Raptors and most Shees.
This past super sunday, at the usual 1/4 mile sand drag, I killied another raptor. After a couple of runs, the owner just said,"Wow, your bike moves." Then he spent the rest of the afternoon "Watching" my R and two piped and jetted Shees drag race. And I did lose some of the runs.

So Kasey, I understand where youre coming from. I also like it when these new quad riders line-up thinking one thing and end up :oops:.

You guys race a whole 1/4 mile in drags?? damn! Thats pretty far.

[Bozman505]

I also have an 85 250R ATC When I race any of the new 4strokes I make sure we have agreed on the ending point.
I love letting them take off first then screamin past them and still beatn by 5or6 bikes most people are shocked that a 18 year old atc can do that.
Then they want to know what mods I have and I just say its ported
with a 38mm Mikuni and they never belive me.

Hey Kasey
How do you match up with the 350-370R ATCs do they even give you a run.

[short4stuff]

i hate to "burst your bubble" but a stock 85-86 250r will "kill" a 350x ...

[Bozman505]

I hate to burst your bubble SHORT4STUFF but your name is not KASEY .
And I am takling about his 500R running with a 350 or 370 big bore 250R
ATC.

[short4stuff]

well sorry i did not mean to come off harsh on that post, but i dont believe there was a "R" after the 350-370 after I posted, I think you edited that, also I just thought it was a X I never knew you could get a 350 or 370 kit for a 250r I thought the biggest was a 330 kit ....

[Bozman505]

Short4STUFF

ITS ALL GOOD JUST A MISUNDERSTANDING

[short4stuff]

yeah ... well i am thinking that the 500 is still gonna kill a 350-370 R fairly easily, unless they have a load of mods.

[daraji250]

Well I asked Mr.Robert in esr and he told me a 380R non powervalve will easily out drag the cr500 in 300ft, because the size of the piston is smaller than the cr500 which makes it lighter and rev faster...

[atctim]

I have an ATC500R. It was built by Jason Hall - and 3leggeddog.

It runs OK.........doesn't run any better or worse than other 70 Horsepower trikes ;)

I plan on MX'ing my 500 next year. Gotta give Lou a run for his money on his MX 500R

There are numerous people here on the boards with ATC500Rs

Here is a pic of mine:

[Louis Mielke]

am i correct in saying that baskets r is the 250r chassis conversion, and tims and louis's are the 500 frames? i always thought the 500 framed conversions sat higher.
