Yes I replaced the bolts, I used some sprocket bolts counter sunk in the plate.

Steel is steel it's only hard if you don't have the proper tools; bench vise, drill press, hammer, muscles.

The primary leads have a coupling, and basically you just have to route it in the same fashion under the tank, just from the other side.

I checked the newer bikes out last night, pre 12+ YZ use a coil on plug setup and the 12+ YZ mount the coil to the frame down spar right between the radiators, they can because of the rear slant engine and the intake track goes upward from the front of the engine.

I had been following your bike lightening routine as well, I never weighed mine but it did make a difference on the trail.  I could out climb anything once I figured out the clutch.  But then I crashed, bad, have since decided to dual sport my bike so everything went back on and then some.  I haven't rode since Valentines day so i'm itching to get out there and see the difference the weight makes.  My advice to all us aging kids... keep riding till you can't, then, just slow down.

 

Some transformer steels are extremely hard and can't be drilled by normal means.  Happy to hear the coil mount isn't made of those.

 

The coil on lug design was abandoned with the move to FI.   The new coil used on the 2012+ WRs, the 2010+ YZ450F and the 2014+ YZ250Fs.  I checked the electrical specs of the coil on plug.  It is NOT compatible with the FI ECU.

 

Sorry to hear about your crash.  I'm a safety first rider, I have nothing to prove.  No big crashes since I bought the bike a year ago.  Presently my right shoulder is sore, but I can't attribute that to a big crash.

 

 

 

My advice to all us aging kids... keep riding till you can't, then, just slow down.

That is great advice.   Once you stop doing something because its hard, you'll stop doing it forever.  Do whatever it takes to keep riding.

 

I've been doing a bit of cross training this summer.  30 miles a week on a hybrid bicycle and 1 challenging trail ride every weekend.  Its been great.

You know, I did not verify the gas like I thought I did.

I will have to re-meause

I thought I topped them all off, but when I looked today.....not.

Would be interested to know the front tire and back tire weights. I just can't see how they would be that far off (your WR to mine). Maybe I am f'n something up but it's not rocket science. Push the front tire onto the scale and take the reading...rinse and repeat for the back.

I tried it with my KTM last night for yuks.

 

2014 KTM 250 XCF-W

 

123 + 134 = 257 lbs

 

KTM claimed wet weight, minus fuel = 232.6 lbs

 

I have about a half tank of gas in it, so add say 6.5 lbs. = 239.1 lbs

 

I have Cycra bark busters, BRP top bar clamp mount for Scotts damper (and damper, of course), Unabiker rad guards, plastic KTM skid plate, and a rear grab strap. That's the only weight I've added.

 

Somehow I doubt all that stuff adds up to 18 lbs, but maybe? So either I did it wrong, it's inaccurate doing one wheel at a time on a bathroom scale, or KTM's listed weight is off.

 

I'll try to do my WR soon as well.

Well, I wouldn't think this method would be more than +/- a lbs or 2 at the most.  If you get the exact same height board to put the opposite wheel on so as to not force any additional weight to the other tire it can't be off a material amount.  Just my thinking though....I didn't stay at a Marriot Express or anything :goofy:

So don't get on the bike :p   It's just an interesting exercise to see if the weights we think and espouse on the inter-web are actually anything close to actual.

I did use a 2x4 on the non-scale wheel. It was pretty close in height.

 

I don't think all my armor/damper weighs 18 lbs, but it probably does weigh around 10 or so? So that would put me within 8 or so pounds of what KTM lists. I'll post up my WR numbers when I get a chance to weigh it.

I think when they say "dry weight" they mean no fluids at all, not just empty gas tank.

Yeah so there would prolly be a quart of motor oil some radiator fluid and some brake fluid.

Probly about a quart in the forks and shock too.

Thankfully nobody uses the old 'dry weight' anymore. The Big 4 have all gone to 'wet weight' to include full of all fluids, full tank of gas, ready to ride. KTM is same but no gas. Not sure on Husky or other boutique brands.

If your going to do it you might go with a empty tank. Since some are large tanks. Also list what bike you have. There are lots of KTM's and WR's.

I edited my previous post to reflect that as well.

Trimming weight is well worth it but a good suspension job will work wonders on the new '12+ WR too.  Stock suspension is good but can be a lot better.

I moved my ignition coil to the same place openbook215 did, except that I removed one of the embedded nuts on the engine mount and placed the coil inside the engine mount.  There is about 1/4" of clearance between the coil and the engine.  Its about 1/2" inside the frame now, pretty protected.

 

I removed the rubber boot from mine as well.

 

Total weight lost was 0.44 pounds.  I kid you not, though I should have maybe left a bit more steel for the magnetic circuit.

 

My bike now weighs 239.06 pounds without fuel.

 

The advertised weight of a 2014 KTM 350 XCF is 237.4 pounds without fuel and it doesn't come with a skid plate.

 

I installed 20mm offset triple clamps as well.

 

I have (poor) pictures of the coil setup if anyone wants to see them.

Have you actually weighed your bike?

Yup you need to weigh the bike. However I have seen wishful internet weighing before.  :smashpc:

Yeah, it's the honor system. Any idea how accurate the truck scales would be for something that weighs ~250lbs? There are 2 public scales within 5 miles from me, been thinking about talking to them to get there opinion on it. I have taken my Motorhome to one and weighed it multiple ways (left front, right front, both...etc) to get an idea how the weight was distributed. Just wonder how they handle lighter weights. It wasn't that expensive. I think I'll inquire.....
