Rockstar Energy Husqvarna Factory Rider Starts his Quest to Defend Cross-Country Rallies World Championship
March 15, 2018 – (Motor Sports Newswire) – Rockstar Energy Husqvarna Factory Racing’s Pablo Quintanilla will re-start his 2018 international rally racing campaign on March 24 to 29 at the Abu Dhabi Desert Challenge in the United Arab Emirates. Working hard towards returning to full competitive fitness following a foot injury sustained during the closing stages of the Dakar Rally, Pablo’s teammate Andrew Short is expected to join the Rockstar Energy Husqvarna Factory Racing squad at the 2018 Merzouga Rally in mid-April.
With the Abu Dhabi Desert Challenge playing host to the opening round of the 2018 FIM Cross-Country Rallies World Championship, the event in the UAE will see Pablo Quintanilla begin the defence of his FIM Cross-Country World Championship title. Securing eighth overall at the 2018 Dakar Rally in January, the Chilean rally star is already looking forward to a solid return to racing aboard his FR 450 Rally machine.
Successfully wrapping up his debut participation at the prestigious Dakar Rally with a top 20 result, Andrew Short has been recuperating from a fractured tibia and fibula on his lower right leg. Resuming his training sessions in the middle of March, the American has his eyes set on making a return to racing at the Merzouga Rally on April 15/20, in the dunes of Morocco.
Celebrating its 28th edition in 2018, the Abu Dhabi Desert Challenge is a six-stage-long rally taking place in the southern part of the United Arab Emirates. Kicking off with the traditional Super Special Stage on Saturday, March 24, the event will continue with five more days of racing in the Liwa Desert before competitors reach the finish line inside the Yas Marina circuit on March 29, 2018.
Pablo Quintanilla: “Abu Dhabi will be our first race after the Dakar and I’m really looking forward to it. It’d be good to start the season carrying the #1 plate on my Husqvarna as the reigning champion. With it being the first race for the new season, it is important for everybody. My goal is to get a good race pace from the beginning in order to be inside the group of leading riders. The season will be long and my plan is to continue improving my pace as the racing goes on. I want to get back my racing speed and also remain strong throughout the event in Abu Dhabi. Taking place in deep sandy dunes, the Desert Challenge is always a tough event and it is also highly probable that we will have to race in high temperatures. It’s going to be a challenge but I’m looking forward to it.”

Looking for some Wiring Harness, Connections and Installation assistance for installing a Tusk Universal Under the Fender LED Taillight with Brake Light on a Husqvarna 2017 TX300
The UTFLight comes with a plastic connector that would work with the tusk enduro lighting kit which i'll be removing so that I can plug into the stock harness.
I've been told the stock harness is the same as what would be included on the TE Model, minus the actual headlight/taillight being present; which is the case for the headlight wiring . it's all there ready to go. For the taillight/brakelight however there is a bit more to be done. There are NO wires running to the rear of the bike or within the SubFrame as some have noted
I'll need to run to existing wires, and could use some guidance for which connectors are needed, if a supplementary harness is required(if so which one) and which wires to connect to on the existing harness. There is very limited info in the manual (for either bike: TE/TX) or complete color harness diagram with info and connector information anywhere that I could find.
I also picked up the Tusk Brake Switch Banjo bolt for the Brembo brakes (two wire, bullet connectors) - https://www.rockymountainatvmc.com/docs/Brake switch instructions.pdf
On the Brake side under the front/bottom of gas tank near radiator there is an existing connector (I think for radiator fan) and from it, two unused wires, I would say for tapping into the existing harness. 1 Solid Brown, 1 Yellow/Red -
Shifter side, near the bottom rear of tank I found taped up cylinder style connector (Someone can enlighten me) i think switch wires ? maybe some terminator, each with the same color wire in as out. One is Gray/Black and the other White/Black
Under the cdi box is a three plug connector with two wires, 1 Brown and 1 White, third unused- i was hopeful this could be the tail light connector but am unsure
Help on harness, connector names /types and setup is very much appreciated
If you own an XR250, many of these tips will apply, however, the carburator jet sizes will be different.
PLEASE ADD YOUR BIKE (eg. XR400) and LOCATION TO YOUR PROFILE.
It really helps others answer your questions.
ALL OF THE LINKS ARE BROKEN!!!
I will fix them as time allows.
Until then the Search Feature and enter "kevin's xr400 mods".
The results will bring up most of the links.
Here are some frequently asked questions I have answered before.
Which XR should I buy?
The longer the straights, the taller the hills, the deeper the sand; the bigger XR you want. The tighter the trail, the smaller hills, firmer terrain; the smaller XR you want.
The XR400 has a great motor that will pull you almost anywhere. You can be sloppy on a hill climb on an XR400, where you have to keep the 250 singing. The XR400 weight is most noticable when you drop it or try to stop it going down a long downhill. (Moooomentum!)
The XR250 feels like a mtn bike compared to the XR400. My friend rode his XR250 for years before decided he needed more power. Even then you can add a 300 kit and get good power.
If you were heading to ride fireroads in Baja, I'd tell you to get the 600/650.
To the tight woods, get the 250.
A lot of both, the 400.
Dual-sporting? Go bigger for more freeway, but don't show up at the trailhead with too big of a bike.
All of the XR's are great. Pick the one that fits your needs.

Gordon's Mods for XR400
The changes to the XR400 have been listed here several times. This list appears to be complete.
In addition, HairyScary discusses how to tell if a part has been updated by the part number. Good tip!
Getting the Spark plug out
It seems the MotionPro spark plug socket does not work on the XR400R, but works on the XR250R.
There is an OEM tool kit being sold on eBay that seems to work.
717448 XR400 oil change
Here is a way to make changing the oil much cleaner.
This tips is really handy if you have a skid plate.

XR400 FAQ by Paul Gortmaker
Paul usually has very good info.
BE CAREFULL with the bolts on the oil filter cover!
An oil covered bolt will not torque at the same rate as a dry bolt.
The friction doesn't build up, the force simply builds until the threads strip.
This is the reason many people strip out these bolts.
Here is an execllent website on bolts, oil, and misc values.
Did you ever wonder why a 8mm box wrench is half as long as a 18mm box wrench?
It is shorter as most 8mm bolts cannot take very much torque.
I highly recommend getting getting an 1/4" socket set.
I bought the Craftsman set at Orchard (owned by Sears), which tends to sell them for less.
What is the Snorkle?
This place has a description and pic, it's easy after you pull the seat. I siliconed a piece of coarse screen (fiberglass) over mine to keep bugs and stuff out. - NORTEXT
717439 XR400/250 Pre-Filter
After pulling the snorkle, there is a big hole on the top of your XR400. My friend showed me this prefilter trick.
767409 XR400 Engine Bog, Pilot jet, and the Fuel Screw
On XR400's twisting the throttle from fully closed to wide open will cause the engine to "bog" or in some cases die.

Inspect and adjust valve clearance while the engine is cold (35C, 95F).
389095 bigger jets (Lists stock jet sizes.)
96-97 XR400's were jetted assuming you would remove the intake and exhaust snorkel.
98 and later XR's were jetted assuming you would leave them in.
739907 Cheap Tool for Setting the Fork Oil Height
There are some really nice tools out there for doing this job.
This tool costs $4.49 at Kragen.
392932 high altitude jetting
There are two big factors for jetting, elevation and temperature.

Allen screws for the XR400 carb
This lists the screws you need to convert the XR400 carb to use allen screws.
Screws for the brake and clutch after removing the stock handguards
TBD - There is a post with the shorter screw part numbers for after the stock handguards are removed. Use search.
Very quick engine hop up
This is a very minimal change that should take less than an hour.
Most of that time is removing the float bowl (3 screws).
If you decide to do the full "Gordon's Mods" later, you will need to replace the jets again.
o Pull the intake snorkle.
o Add a UniFilter.
o Pilot jet to 55, main jet to 155. (Assuming sea level and moderate air temps.)

Pull the intake snorkle, UniFilter, 60 pilot jet, 162 main jet.
(Depending on altitude and temp.)
What to add to a new XR400 or XR250?
Acerbis wrap around style handguards (saves levers and bars as they don't dig in)
Baja Designs skid plate (Made by Utah Sports Cycle)
Acerbis fork/disc protector
Grease headset and rear linkage
Spend you money on the suspension, not a pipe!
First get some stiffer fork springs (96-97, 98-99 years)
Fork revalve (cost: 2 qts of oil & time)
Shock revalve (cost: oil, nitrogen, shim stack, friend who knows shocks)
Jetting for Altitude (XR400)
Assuming at sea level and 68 degrees, you would use a 60 pilot and 162 main.
At 5000 feet and 68 degrees.
5000 feet and 68 degrees.
Main 0.96 * 162 = 155 -> 155 main
Pilot 0.92 * 60 = 50.6 -> 55 pilot
Due to your elevation, you have less air and less fuel.
Your bike will not behave the same as a bike at sealevel.
First, check the fuel screw. If it does not affect the idle speed, you have the wrong one.
