ATC 600X ... '87 XR 600 Conversion Project

[sandpuppi101]

Well I've been researching this for quite a long time and I finally got a chance to finally do this project. It started out as an '87 XR 600,the guy who had it lost interest in it ,so when I found out about the bike I had to get it.The motor was already out when I bought it,he had the tranny rebuilt and a new Barnett clutch and basket put in he said,the crank and rod are also brand spankin new also,the bummer... NO Head !! But I have everything else.
So far I stripped it down,and put on the frt end off an '86 350X and got the swinger on the rear ,it was'nt too bad of a mod so far.I am sending out the rolling chasis this weekend to get the rake brought back 3 inch's. I would tackle that but.. this being a 600 motor the downtube and the upper part of the neck are the oil resivoir,thus I figure I will let a pro welder tackle that,and I am planning a 4 inch extended swinger.I have modded a '85 200X swinger and with the help of a couple bushing's ,it look's like the sproket will line up pretty nice.
As far as incorperating the motor into a 350X frame,that ain't gonna happen and be safe. I am worried about the torque this motor is gonna have so I am gonna go with the existing frame and take part of the sub frame off a '86 350X frame,so when all is done the stock 350X tank and fenders should work.As you can see by the motors side by side ,350X on left /600XR on the right - the only thing these have in common is the Honda name if you ask me. I am planning for a drag only machine but maybe this could be a Wild Trail machine,I guess I'll see how all this goes 1st.. I'll keep posting pic's .

try changin it to a trailing front axle insted of a leading like you got it now.. that will get it closer to what you want.

[sandpuppi101]

Yeah I agree on changing the trailing ,but it's still gonna put me a few inch's off. I was actually thinking of the R set up for the frt.

[SpeedBump]

I luv Conversions!!! Keep at it, and we'll line up all the wild rides at TF for a group fOtO!

I agree with the others....I would just go with a 250R front end.

83-84 250R front forks in the 350X triples will get you the rake you want and no cutting on the frame. The 350X triples have no rake built in to them, where-as the 250R triples do.

If memory serves me corectly 83-84 R forks will fit right in the 350X triples.

Looks like a fun project!

TRI-Z forks will also fit.

[sandpuppi101]

The Tri-forks are literally the same size as the 350X are'nt they? Yeah I hope it's gonna be a fun project,I hope..

[200x newby]

yeah i wouldnt mess with cutting and welding the rake looks fine and if you want to drag it like you say then you want a little more rake to spread things out

[4cylinders]

hey, I'd leave the front end as is until you've ridden it. you may need that extra weight out front. looks good so far.

[jeddy]

If you want a cut down frame I would sell you my first one. I lowered the seat mounting part a couple inches, and cleaned up the rear down tubes. I also made a new upper shock mount to clear the lowered seat. I went back to the original XR600 frame so I could use the XR shock and linkage (the other used a YZ250 shock with no linkage). I can send you some pictures if you want.

I also thought about going to the rear mount on the front end since I'm using 350X forks, but I figure the length will help me since I plan to mostly just drag race it in the sand.

If someone tells me how to post pics I can put some up. Mines a '93 XR600 with parts of an '86 350X...

L8,

[4cylinders]

hey, post the pics so we can all check them out. go to manage attachments to add pics.

[jeddy]

See if these show up...Obviously the engine is out of it now. I replaced some gears and put a new crank/piston/cam in it. Should be up and running again by this weekend. I will take some pictures of other frame. Let me know if you can't see these. Thanks,

i like the stance of it

[sandpuppi101]

Kinda hard to see with that angle on the frt rake Jeddy.. Is it about the same as mine,and what swinger did you go with.I was thinking of extending 4 " ,but your's looks further.How fast does that thing go anyways. What gearing are you running.

here's "My Mutt"......

1980 xr500 frame conversion
