Other choices are glass wool, which is next in temperature resistance, and "rock" wool or mineral wool the highest temperature resistance. How tightly packed the "wool" is affects how quiet it will be....loosely packed generally more sound absorbing, but lest durable. I further assume FMF sells materials to repack the muffler. Such designs require occasional rebuilding (re-stuffing). So much for how these mufflers are designed....the bit of steel wool looks like a wad of steel wool that was left loose in the muffler during a sloppy packing job, rather than dislodged during usage. I'd email FMF and see what they think. Again...all my opinion.
Here's a hot tip, find a Refractory company in your area, they specialize in high temperature brickwork, castable compounds and insulation. Ask if they'll sell you some ceramic wool, repack your muffler with this. Heavy duty stuff will last longer than the bike and will be good at keeping the outside of the muffler cool. Easy to work with too, but wear gloves as it will itch like a MoFo. Used to be a refractory mason so I gots some first hand experience with it.

I believe it is often called "rock wool". I've seen it here in MI where it is used as insulation in making kilns to fire pottery, or in the ovens that heat glass for glass blowing and decorative glass making. But also Rocky Mt ATV & Motorcycle may have sold repacking kits with it

yeah rock wool is exactly what the name implies, minerals heated to melted temps and spun into wool. I've used Kaowool too but the stuff I was thinking about was much tougher, we lined a whole Visbreaker with it and it's still in there five years later. There's varying strengths in it.

I have noticed this on occasion with mine. It was chain noise. The spec in the owners manual...IN MY OPINION is too tight if set with no rider on it...if set with weight on the seat it's better....but since this bike is so short on power, at speed, on and off the power, chain slop is quite noticeable. This noise is noticeable IN MY OPINION because the bike is so quiet. If you have a 13T sprocket without the rubber on it like the stock 14T,there will be more chain noise. (The rubber is to reduce noise). Also look for sprocket misalignment and side wear on the teeth.
FORGOT TO ADD: Do you have an aluminum aftermarket bash plate? They buzz as bolts loosen up....and help reflect/amplify engine noise

New CRF250L owner. Picked her up last week after a solid test ride. Had to have her. Only thing I've done is remove the snorkel and backfire screen from the filter. This helped smooth out higher-speed driving a lot. I will be commuting 25 miles per day on the CRF and using it as my weekend toy.

Yeah, the chain if adjusted were you think it's good, will be wrong when you get on. If you can be someplace with no traffic, pull the clutch, and hit the kill switch, and see if the noise stops. Loose chain is better than tight, you'll toast the output shaft bearing.

I like to adjust with me and all my junk on board,if I cant reach down while I'm sitting on the seat I use a coat hanger to pull on the chain to make sure its loose enough,better to loose than to tight.

Anybody getting ready to get a new tire(s), 40% off Dunlop, 31% off Metzler. Plus 5% off of that, using those codes. Expires 7/31 11:59. http://www.motorcycle-superstore.com...vid=1160297728

If you've got a skid plate then it's most likely that.

They do this every now and then. When I got one in the spring, the discount put me below the free shipping number, and they charged me. Sent off and email to CS, and they fixed it. Then others posted they wouldn't. I didn't even need a tire at the time, but figured when I did need one, no sale. Yeah I went with the D606 120/90-18. The front has a lot left in it, not sure what I'll go with when the time comes.

2013 DR200se vs CRF250L {stock/brand new} adv touring

I've given up on finding a 400lb Dual Sport to replace my car as my primary vehicle. I just can't find the right bike. Honda came close with the engine of the NC700X, but are going the wrong way with the 2014's that have 50 more cc.

I'd like to do an eduro this Winter
The trip would be for several months (4-8). My dream car for the journey would be a used 2013 Subaru XV Crosstrek. 148 HP, good fuel economy for the AWD.
A lot of hipsters bought the car brand new and seem to be disapointed in the lack of power, and the loud engine noise. Both of which I'm cool with seeing the purpose I have for her. If I can't find one for a good price, I'll get a MC. Note, the winter trip would start two months earlier on a car.


The trek would start in VA, and go into the Deep South, then hug the Gulf Coast, and then cross the C. Divide (in New Mexico), hit the Cali coast and into N.W. Washington. From here, I'd take a ferry to Skagway/Haines Alaska, and then back down to Juneua, then west to either Homer or Whittier. The temps will easily get into the teens and be mostly in the upper 20s in Alaska, even by April.
As the summer approaches, I'll ride The Dalton.
Afterwards, I'll see where I'm at and ride back east taking a Northern route.

I orginally wanted my primary DS MC to have a less is more type of ethos. Less Skynet Technology and Gremlins to go wrong.

However, I'm thinking the Honda 250 would be better for the type of trek I have planned. Sure, the Gremlins are there with the FI, and computer display, and much more, but I'd have a warrenty for such matters. If I'm having problems with the bike, and can sale her after the journey, if the bike is great, I can keep her for a communter.

Now for the brief comparison.
DR's pros:
The 200se allows a much better range. I'll say the miliage is about the same on gas, but the extra 1.4 gallon tank puts the DR beyond Thunder Dome.
I plan on purchasing two, 2 gallon rotopax tanks for the journey (they would be set up on the foot pegs. This would have the bikes well over the 500 mile range.

Moving around with engine off: Lighter: 278lbs weight vs 230lbs wet. Keep in mind, this is not even adjusting for gas. Furthermore, seat height is 31.9."

Parts: More avaliable. Granted she was gone for two years.

Better online support. Honda just came out.

Way less Gremlins to trouble shot.

Display: Tachomoter is present.

seat and rear area looks bigger and flatter to store gear.

__
Honda Pros:

1. 50 extra cc, give her that extra 10mph the DR needs for high way riding. Note, Innterstates should be still avoided.

2. After the initial 600 mile oil change, I'm good for 8,000 miles. ( I read this on this thread. this seems too good to be true.)
I'm really interested in low maintenance.

3. 6th gear for crusing on America's highways.

4. FI for those cold morning starts. Granted, most of the temps will be well above 0 degrees C.

5. 34.7" Seat gives commanding views while on the go.

6. Seat is more comfortable.

7. Heavier weight provides better stablity in windy weather.

8. DOHC for smoother rides at higher RPMs.

9. Better ergos.

__
I was shocked at the price of the Honda, I figured it would be $2,000 more for such a new bike. __

$4,199 vs $4,699.

I know, you'all are biased, what brand new bike would you recommend for someone not mechanically inclined and riding alone?

Thanks for reading.
