My revitalized XR4

Recommended Posts

The bike looks awesome man! Got some nice touches on there, black frame and all. Looks to be very well done.

How's it perform? I'm pretty satisfied with mine with the Edelbrock pumper. I hope someday to have the money for Hotcams and a 426 or a 440 kit. Should probably get the suspension redone for my fatass though first.

Looks Great!!

I sure wanted the A-loop kit when I was working on the new look but it is a chunk of change. How does it help your riding? It appears that it would allow you to move around alot more than stock.

The 426 kit ups the compression quite a bit and along with the pumper, I'm able to just "nail" the throttle in second and third and the front end comes right up. I'm quite satisfied.

The a-loop kit is awesome, I decided I needed it after I squashed the jewels after a hard landing with that turned up seat thing that comes stock. Give you a lot more room to move up on the bike. Make the bike feel like a nimble motocrosser.

The front forks weren't tomuchof a hassle, Got all the parts off Ebay, whole front end in fact, Found a local machinist to turn down the steering stem to match XR specs, and it all bolted right up. You can get by with the XR brake caliper. You can find info in the forums, just search for CR fork conversion,or USD forks on a XR400, etc...

StillKickin,

Dude,I saw a picture of your bike and I was INSPIRED!!, Of course I had to go all the way with extras. My wife realized she should't have denied me a new bike. I was looking at a Husky TE510. I much happier with what I got now. Minimal maintenance, and it boogies. Tip to all you guys out there. When you want to rebuild your current bike, Just tell you're wife you like to get a new one and she will be happy to let you fix yours up.

I'll have to remember that. Wait, I'm not married, so I don't have to worry about it :ride:

I've considered the A-loop kit for that same reason (came limping into the house one day) but I can't bring myself to spend 500 bucks for less fuel capacity (kinda nice being able to hold enough for about 100 miles when I'm out dualsporting)

Oh yeah, that previous tip is for you married guys out there, but you may end up gettin "bitched" at anyway for spending to much time in the garage and forgetting to pay bills, takin out the garbage, feedin the kids....

Isn't that what the wife is for?

:ride:

Perhaps that's why I am still single :banana:

Hey if you get bitched at and she kicks you out to the garage, that's just more time to spend with the bike.

Here is the question that hasnt been asked yet, how does the e start do with the stage 2 cam since you dont have the auto decomp anymore? DO you have to pull the compression release on the handle bars to get it to spin over?

yeah, ocaasionally I have to use the DeComp lever, but it's no big deal. Got all the parts off Ebay from a 400ex, Cut the wiring harness down to fit my XR and wired it to the Baja Designs Kit.

Sweet bike!

Please tell me more about the e-start. What parts did you need/replace from the ex400 quad?

And please tell me more about the CR forks. Did you have to use the clamps from the cr or can you use the ones on the 400? What years cr 250 forks can you use? What about the Brake Caliper and Wheel fitments?

I also have done a lot of mods to mine (Barnum Pro built bike, 416, Pumper Carb, Heads, Valves, Clutch, Suspension Re-valved and springs to match. The only thing that has not been done is to replace the forks with Cr forks and add electric start. I would love to not have to kick this thing over. I am only 5'8" and it's a lot of bike to kick over with a stage 2 cam in it. You have to use the De-comp lever.

OK here goes

For the E-Start

2 options

1) Joe Racer Kit... go to JoeRacer.com, I chose not to go that way, too expensive for a rinky-dink adapter but lots of good information.

2) 400ex parts.. The way I went. There is an abundance of these parts on Ebay.

The following are needed from a 400ex:

Crankshaft and Balancer (don't know why the balancer is needed but I got it anyway)

Stator and pick-up coil

Flywheel, one way clutch assembly, starter ring gear

Starter motor with gears

Left side cover

Starter gear cover

All left side cover bolts

Complete 400ex wiring harness including starter relay,CDI, battery cables. I also included the key switch on mine.

Complete engine gasket set for a 400ex, lower gasket set for XR400 (easiest way)

New crank bearings.

New seal kit.

A 400ex service manual (search for 400ex service manual pdf)

Time

Did I forget anything?

This will require a complete engine tear down, not to difficult, have a clean work area, take your time, read the manual carefully, get some zip lock baggies, don't disassemble things that you don't need to (transmission, etc.)

After tear down, reassemble per the 400ex manual.

ALSO: purchase a flywheel puller, and you will need a bearing puller to get the bearings off the crank.

You will also have to get a Yuasa Battery (can't remember the part number)the that is installed in the Airbox. I made a killer bracket for mine. More info at Joe Racer.

The wiring for the kit is a liitle tricky, I rigged mine up to work with my baja designs front wiring, also used a start button from a CRF450x.

Now the Front forks.

Again purchased all parts through Ebay. Look for Ebay store KEEPITROOSTIN. They have late model parts in excellent condition.

You will need the forks,clamps, handlebar clamps and the front wheel and front axle. You can use your existing Brake Caliper. Also get the fork guards and bolts.

There is 2 ways you can modify it to fit your XR.

1) Have the stem pressed out of your existing XR bottom clamp and pressed into the CR bottom clamp, You will have to have a bushing made so it will fit. (The XR stem is smaller than the CR stem). Here's a link to that MOD.

http://www.4strokes.com/forums/topic.asp?TOPIC_ID=20125&SearchTerms=cr,forks,,XR400

There are other threads there to give you ideas also.

I chose to have the CR250 fork stem turned down to match the XR4 stem. When that is done, everything just bolts right up.

Hope this Helps

      What’s up guys. Totally new here picked up an XR400R I live in the desert so I’m riding often and enjoy it. But I am having some issues with my  01 XR400R. I brought it out this morning for a putt and it seems to be choking up in the top of second. Like a bog an go bog an go. First seemed fine and third I didn’t make it high enough into the rpms to see. Before I brought it back to the garage. Yesterday I also changed the air filter back to an uni. I had seen the other one had a hole in it and the box was dirty gunned up and oily. I removed the airbox gave it a good clean out wiped everything down very well put a piece of screen over the snorkel Or where it used to be I should say. “Lightly oiled the filter.Also the spark arrester an tip for the bike it did not come with I ended up making one with a piece of flat steel and drilling holes. Whilst doing this. I found also a crack in the pipe. It almost sounds as like there’s a vacuuming or whistle? When revving.The first one I had made worked fine I had no issues. This one I am wondering maybe if it’s a cause of a little too much back pressure.So I’m assuming it’s either a Carb or exhaust problem. Or something that could totally be minuscule. Or major issue. Would definitely like some second opinions and any advice would be greatly appreciated. Thanks guys! 
      TWISTIN THROTTLES & CRACKN BOTTLES

      My lanky 14 year old boy started showing an interest in riding MX/Off-Road so I sourced the best beginner friendly, yet dirt worthy, bike I could find: an Ol' Honda XR250R (2004). So far I've replaced a few clutch levers and perches with stock parts. That's gotten old and I'm looking to upgrade to an ASV or Torc1 type fold-able clutch/perch brake combo. Went to purchase online today and to my surprise there were no such parts listed for the XRs. I saw plenty of CRF/CRF-X choices and they seem to differ depending on generation. Obviously I can use nearly any perch/clutch combo as long as the two match; but I was wondering if anyone knew which of these levers was closest to stock? Also, will the first gen CRF250X brake lever work on the XR? These may be stupid questions to some; but I'd rather ask a dumb question than drop money on an ASV brake lever I can't use. Thanks for any help.

      Im currently in the market for an xr400r, and considering buying one that's had some heavy engine work done. The current owner claims to have bought it from a friend who's an XR enthusiast. The PO installed a big bore kit and high comp piston, as well as a xrs only pumper carb, rsw triple clamp, aftermarket clutch, street lights, and a whole bunch of bling.
       
      My main concern is the effect the upgrades will have on the engine's longevity. How much quicker will I be going through top ends with the setup on this bike as opposed to a stock setup, and should I be worrying at all about bottom end longevity as well? I wouldn't mind having to eventually redo the top end, but I don't want to deal with a race bike type top end rebuild schedule on an XR. 
      Is there anyone here who's running a bike similar to this one who can give some advice?

      I have a 2001 Honda XR400R. It has a whirring/grinding sound in the lower end and a vibration in the top end. I pulled the valve cover and everything looks good. Decompression lever looks to be in order. Anyone know where I should start looking or just rebuild the whole engine. Ballin on a budget, but really love this bike. It looks like it’s new otherwise. Oil was jet black and thin. Thanks in advance!
