ok I'm busted

my mind is playing tricks on me, really remembered the 10 min. Maybe that was the time it took me to decide to repack...
I'll try to do that in 29 next time

I'd be stoked if I could get away with a "new" rear only 3 or 4 times a year. Actually, last year was just about that..except it was due to a lack of riding, not tire choice.

Here in our rocks, I get about 3 to 4 rides on a 756 before it's slickery. When I was riding 1 to 2 times per week...that sucked.

Dunlop 952, Metzler MC5, Pirelli MT16 & 18, and the Maxxis IT or SI rear all lasted about double that. The KDX was less harsh on tires than the KX. One bad day on the KX (spinning up hills) can be torture on the 756. Tire spin was less of a problem on the KDX, especially on a bad day.

I actually didn't mind the 739 rear tire out here, I wouldn't buy one...but, I'd take one.

I agree whole heartedly with CC on the 756 for traction. It's my favorite. I've never run one up front. My fav. is the Maxxis SI up front. It's been the only one I've tried that stayed predictable throughout it's wear. 739 up front is plain scarey for me. No warning, then me on the ground.

The last time I re-packet my silencer, it took me 10 minutes just to fix the Moose super easy, pre rolled, slip on packing that I somehow messed up. That didn't include any of the cleaning time or packing time.

It probably takes me 45 minutes. I clean the insides up real purdy

Two sizes:

120/90x18 about the same size as 110/100-18
110/90x18 about the same size as 100/100-18

If your running the 110 in the 952, it will definately look smaller than the 110 in the 756. Thats because its a 90 profile tire instead of 100...no idea why Dunlop decided to size thier 952 18's like that.

When I bought the D952, the 110/90x18 about the same size as 100/100-18 was the only type available at that time. I remember there was only ONE CHOICE

ive got over 500 miles out of my stock tyres... the rears just bout stuffed but il get a few more rides out of it

QC how long are your rides? I think I have about 300 miles on mine and they are in decent condition and were the cheapest they had. What do you run to prevent flats in all the rocks? I run an old tube b/w the tire and tube but that doesn't work all the time but better than before.

Well I looked at the D756's but went with the Pirelli 44's. As I get into this, I'm sure that I will try new things and come up with what is good under me.

What exactly does the packing do?

riding in desert like conditions in south Texas I have found only one tire that holds up well Maxxis desert IT. I like the 756 good all around tire but three a year was a bad habit. I will try the perelli MT16 next.

Just checked out the FMF site and downloaded and printed the repacking instructions. Sounds fairly simple to do.

1. It muffles exhaust noise.
2. It provides a tuning component to the exhaust (by damping sonics). A two stroke exhaust is 'tuned' to various performance characteristics depending on what is desired. That's why (for example) the two FmF pipes, rev/torque, are physically differently sized. The different sizes provide different sonic characteristics that enhance engine performance in different RPM ranges.

Compare a silencer that needs to be repacked (or was packed poorly) to a freshly, correctly packed silencer and you will find the latter is:
1. Quieter.
2. Improves throttle response and power output in lower throttle ranges.

'More sound, less ground!' is not only a responsible attitude for the ORV community to have, it's also beneficial to the rider.

Rides are typically around 45 miles. Mostly ST and rocky sand washes with lots of elevation changes. Tires would last a whole lot longer if we ever got any rain.

The Hengefeld's own a M/C dealership in Flagstaff. Steve Hengefeld ran a club AMRA race last season on a D756. The race was a Hare Sacramble style race and was approx. 60 miles of mostly ST. The D756 was devoid of knobs by the gas stop...cords were showing at the finish.

His dad was supposed to put on a different Dunlop tire, oops.

Knock on wood! I haven't had issues with flats. I run Bridgestone extra HD tubes. I run 12psi in the rear and 10psi up front. Mostly 1st-3rd gear stuff...on the KX. 2nd gear-4th on the KDX.

riding in south Texas consist of rocks sand roots, cactus and lots of thorny shrubs and trees. when I pull tires off they are full of thorns and if that doesn't try to ruin your day a rock or hard pack with embedded shale rock will try to slice and dice the tire. The standard I have come to use is an ultra heavy tube with lots of Baby powder when installing, the powder helps to prevent pinch flats then after bead is seated I run 8oz of slime in the front 12oz in the rear. I found 8oz in the rear was not enough for the larger tire. I run 12-14 psi in the tires depending on speed and traction of the given day also the amount of rim roll (the black marks from the tire on the rim from the tire rolling up on it) I get.
this has worked for me for 2 years with out a flat on a ride.

Guys,

I installed Pirelli MT32's in the rear and MT44's in the front. Today was the first day out, what a difference they made over the D739's. It know wheelies in third for the first time without clutching it.
