Maybe, who raised how?

I went a little over +3 on the bars, with stock cables.

Rotate the throttle tube down, and re-route the clutch cable so it goes behind the triple clamp, not in front. That's barely visible in the picture under the tank vent hose and to the left of the left riser.

Later, I swapped out the whole clutch + decomp perch and cables with ones from a KTM LC4. I had to do a bit of bracket fabbing but the pull is much smoother and it gets rid of the separate decomp perch on the bars.

looks good, ill give it a go when i get home if i can.
iirc the throttles were ok, but the clutch and decomp were getting close to max. cant remember if i routed behind the triple though

In stock form that tank bag isn't so hot. Got it here: http://www.rockymountainatvmc.com/p/...Tank-Bag-Black

The tank side is cordura nylon, which I figured would scuff up the tank. Since I'm a tad OCD about keeping my bike as clean as possible I sewed a microfiber cloth to the underside. Still has the problem of no straps going under the tank so that's the current project. It's okay if there's fairly heavy stuff in the bags but if they're too light they flip up onto my legs while I ride. Its incredibly annoying. Here's another shot:

Yup...exactly the issue I encountered....I ended up sewing a couple of "D" rings on the lower inner front corners of the bag, and lash it with some small diameter bungie stretch cord from the boat store

not wonderful...just functional...and being OCD is OK too

A couple bounces and what was left of the tissue paper thick SA bolt just ripped and it's free. Gonna strap the frame my platform ATV jack and see how much the engine will move up and forward and tilt to the side to weasel the engine+swing arm out of the frame. If it does, I'll consider it an act of God. I think the sawzall will have to come to the rescue and "shorten" the swing arm. Fortunately I bought a used one. That's followed by the treat of getting the SA bolt out of the ass end of the crankcase. No pix though

I was able to weasel the engine with the swing arm attached out the right hand side of the frame. Had to cut up the swing arm though...and the alloy in the cast part of the swing arm must have loads of silicon....ate 3 sawzall blades and slashed it up like Doc did

Followed most of Dr. Lewall's guidelines after that....to get the last bit of bolt out of the rear of the crankcase required HEAT...especially on the steel bushing in the rear of the crankcase on the sprocket side....serious rust...once it moved a tad, I soaked it with aerokroil, then polished the part of the bolt that gets exposed when pounding it back and forth....back and forth, juice it up...pound some more...and it was out and done in 15 minutes or so

Talk about relieved. Thanks Doc L for documenting his repair process.

DrLewall · 11-09-2012, 03:59 PM

TADA!! Glad you got it out..now, plan on servicing that booger at least once a year! and if you sell it, tell the new owner to do the same, or not

Yup...that sucker is gonna get plenty-o-lube, and the whole bike will get cleaned up and given a once over.

Noticed my replacement carb choke plate has 2 very significant sized slotted holes in it....has anyone seen one that is blank or a more appropriate size for a 400 engine?

DrLewall · 11-09-2012, 04:40 PM

does the choke plate have the backfire plates on it or does the choke plate just have two holes, like the XRsonly choke plate?

here are the backfire plates

so, is yours like any of these posted above?

btw, I have the XRsonly plate in mine..my backfire plates were abt to fall off and I didnt want to suck anything into the jug...knowatimean?

Ed@Ford · 11-09-2012, 04:51 PM

Mine is like the red one...I went back over the thread and Laramie C4 said 7/32"...DAMN that's small....but nows the time to deal with it...the carb is laying on my garage floor!!...gotta go out there and check to see if it's steel or not......

Bullamakanka · 11-09-2012, 06:34 PM

The "Red" one is the one you want to use. The other ones have a tendency to snap the metal flap off which then decides to enter the cylinder head causing all sorts of expensive issues. Hence the XR's only red one is a modified version to address this issue.

I need to paint my wheels black. Mine looks retro as fuk. The purple adds 3hp though

Wallrat · 11-09-2012, 08:56 PM

Thanks. Its been a good bike and gets a lot of attention.

Just used Engine Enamel 400° for the engine, 2000° on the pipe: http://www.duplicolor.com/products/enginePaint/

Front fender shown there is an acerbis supermoto:
http://www.rockymountainatvmc.com/p/...Fender-YZ-Blue

I couldn't ever get used to the 17" radius of the fender with a 21" wheel so I ended up swapping it out to a regular CRF450 one which I had to trim a few inches off the back of it to clear the frame.

Rear fender is just the standard XR400 one from Polisport: http://www.rockymountainatvmc.com/p/...6-Honda-XR400R

Yep, 450 forks with the Emig conversion stem: http://www.emigracing.com/CRX46.htm

Can see all the parts I've used listed here: http://2wheelsplz.blogspot.com/2012/...fications.html

Cool. Thanks.

My Xr won't idle down all the way to the set idle speed without a snap of throttle. I replaced the exhaust inset but it was doing it before. Really haven't gotten into the bikes mechanics yet as its a good wild ride since I've had it but this seems to be a problem since it doesn't slow the bike down for lights and big turns. Thanks ahead people.

tonusmaximus · 11-10-2012, 06:17 PM

it idles down but just to 1800 rpm or so without snapping it. snap throttle it goes to around 1400 where i want it. it wont go down anymore while pushing down on the wheel where cables meet on carb with screw driver so i believe cables are ok. carb coming off soon to check jetting and cleaning plus choke plate. could this scenario happen with jetting off?
