(3) bikes, (3) plugs, (1) possible pre-mix ratio? Leaving tomorrow.

Starting tomorrow, for (4) days, we'll be hitting the Mojave high desert out here in CA. Temp will be mid to high 70's in the 3300-4k ft range mostly.

We're going to have a number of bikes out there, and (3) of the bikes will be 2 strokes.

An '87XC430, a '96360 and a '04WR250.

I need confirmation and recommendations on the below based on the above fact it's higher dez and in the 60's and 70's degree F:

1: Confirm a B9EG is the correct plug for the 430

2: What plug for the 360? Non resistor type right?

3: BR9EIX came with 250, but from the lengthy discussion on http://www.thumpertalk.com/forum/showthread.php?t=614722 I'm unsure really which one, but it seems possibly the B9EG is the way to go on this one?

Maybe all (3) can use the same plug type?

All gaped the same too by chance?

Also, I've read a number of threads on pre-mix ratios for all these bikes, and it's all over the map.

Is there a safe/recommended pre-mix ratio I can use on all (3) these bikes?

I'm more for reliability and durability than I am all out performance by the way.

Or do I need to break them out some?

I realize jetting plays into this too, just assume jetting we would leave on the richer side or just shy thereof.

Thanks for the help guys.... :D

a standard on the safe side mix ratio would be 32-1 with a good quality oil like klotz r50 or spectro etc.

I've been out of the 2 stroke game for so long, but is Maxima Super M considered a high quality pre mix oil these days? I have a few new quarts of that, that's why I ask. If I need to go out and buy something different that's more accommodating for these bikes, I will, just need to know.

Is 32:1 too conservative, or just right in your mind, for all 3?

I run the same plug BR8EG in 88 WRK 125, 93 360, 87 WR250, 02 wr360 and 44:1 good sythetic for all. We do want a ride report with photos. Have fun.

Of cos. I will do my best to get some actual pics, etc. Full report as well.

Have you changed (tried) to the non-resitor type in any of these bikes?

That thread I posted above seemed fairly strict about saying the R plugs don't do well in the 250 analog ignitions.... Although it did say the WR125's did like the R plug in the upper RPM's, and they weren't sure why.

Thanks for the feedback too! :D

I would run the 9 series plug ( take a box of the 8 series also incase they foul ) , Weather it be the Iridium NGK plug or basic NGK .

40:1 has work perfect for me , using Synthetic Oil's & 92 octane rating gas.

Oil's have come long way's form the 80's & 90's.

Just Make sure you use a Full synthetic 2 stroke oil ( AMS oil , Motorex , Belray, ect . . . )

Have NEW or Clean Air Filter's on Hand for all the bikes.

Change gear fluid on the 2 strokes, Top Off the Radiator fluid OR flush it out and add Fresh Fluid.

Brake fluid Check & top off.

Chain Lube -

Grease everything that need to be, Inspect all .

Take a Tire Patch Kit & Air Pump .

Pretty much it ... you should be good to go!

Thanks cease.... great feedback and thanks for thinking of the little extras too!

I just returned some Super M and picked up Yamalube 2R, but it's not a full Synthetic. Now I will go and see if I can get something else in the interim.

I don't have Amsoil on hand, but would like to try it, my dad's a dealer so we can get it as wholesale, since we have so many cars/trucks, he needed to be one in order to get the better pricing.

Ryan, I have been using Yamalube 2R since day one on my 125, and when I replaced the top end the powervalvle was not gummed up whatsoever, the cylinder was also in fantastic shape.

I will second the 40-1 vote especially on the range of bikes you are using.


Dope. Good deal surfer. I ended up picking up 2R and taking back the Super M, but hadn't yet seen ceases' comments about 100% synthetic. Good thing, as a kid, I used 2R religiously in all my old 2 strokes, blasters, banshee's, 250R's, etc without hiccup, and the husky's have an older school design, so I should be ok for this trip.

I am also going to try the Amsoil dominator stuff I think too.

40:1 is what I'm going to try based on the feedback since we have the bikes a little on the richer side.

40-1 is a good universal ratio.

      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

      I'm just putting the finishing touches on my streamlined version of the BOZZA DRAFT shop manual for the 610. I've removed everything but the english language & made it easy to find what you're looking for. I re-wrote the part about the computer with many thanks to Xfool but I'd like a little proof reading here. In particular I'm not real sure about the Service Interval section. If any of you would be willing to double check what I've got here & report back with any errors or omitions I'd be greatful. (I added another section on adding & removing screens) Also I don't know if it's legal to post this for public consumption but I'd be happy to share it with anyone who want's a copy.

      10/17/08 UPDATE! I posted more photos on page 2. Not all pictures are on page 1. I will constantly be adding more photos as I go along.
      Many of you have heard of my starting/idle problems with the 610. Carburetion has been ruled-out time and time again. I sensed something else was going on. The engine has never wanted to idle down, sounded like there was a load on it even in neutral. Since I had metal filings in my oil when I first got it, I have now decided to overhaul it and make everything ship-shape. It turns out that I was correct- there is some valve damage that I will talk about later.
      I don't like to take apart dirty engines and get the dirt inside 'em

      A little gross.

      My cleaning station:

      A little better now

      Clutch removal:

      after removing springs

      bottom of pressure plate

      everything looked decent as far as wear

      after removing plates

      basket after removing hub

      Area after removing basket.

      Removing the starter gear with snap ring pliers

      More to come. I'm uploading pictures of the case splitting, etc...
      I'll try to ease off on the photo-over-obsession. The next batch of info/photos will be a little more interesting.
      Comments and suggestions are appreciated. I'm already ordering parts from George so before I know it, I'll be just waiting on new parts (after a little more cleaning.
