Maybe they moved them to the back so they wouldn't look like posers..

but I think the big orange building defines their allegiance... boy did I get some dirty looks..

I got some interesting looks myself when I accidentally pulled into a Harley Dealership a few weeks ago thinking it was the Yamaha dealer that ended up being just down the street. They didn't seem to understand what kind of bike I was riding (black 2009 WR250X).

man, that is a home run.
you might think the other 3 big 4 might take notice and be working on something. it just shows how stale the japanese small bore ds offerings have been for awhile.

I just got the Shinko 244's mounted up on my WRX. Good looking tires. I had the tire shop spin them and they were so close the shop didn't want to add any weights. I had Ride-On TPS in my last tire/tube setup and it worked very well. It's on backorder, but I'll probably do that again here.

Since I could not find info from Shinko on the tire dimensions, I measured the outside diameter of the tire to double check while it's off the bike. I figured that's going to be the most accurate way to get the O.D. and it could be difficult to get an exact measurement while ON the bike.

Also, the knobs are pretty tall, so I'd expect the diameter to reduce quite a bit through the lifetime wear of the tire.

The 5.10-17 Shinko 244 Dual Sport rear tire I'll be using has an outside diameter of 25-1/2". That's mounted up on the wheel and at 22 psi.

I'll be starting with an RK sprocket/chain set from the Sprocket Center with 13/43 sprockets. This is a similar on-the-road drive ratio (similar RPM at a given road speed) to the popular 13/46 sprockets using the significantly taller Dunlop D606's on the WRR 18" wheels.

It's not exactly equal, but in the ballpark (plus 0.06:1 near as I can figure).

I just bought this WRX with 2500 miles on it. Unknown why, but the chain guide wear is at the opposite end of the guide from what people typically show on WRR's. I figure that'll change with the new sprockets/chain and with me probably tensioning it differently than the PO.


OK, rambled a bit. Recap: 5.10-17 Shinko 244 outside diameter is 25-1/2" when brand new.

I forgot the rack the day we visited the dealership for those pics. I will get a pic of it tomorrow, as I have a WR in the shop.
Thanks

Is this accurate? can you field disassemble the pump? How does it connect on the high pressure side? Could be a good idea...

It would make trail replacement take a couple minutes longer, but the pump would be a lot easier to carry less likely to be damaged.

I don't know for sure, but someone took a pump a part to produce the picture. Looking at my new spare pump, it looks like popping three plastic tabs and being able to replace a small black hose between the two white pieces of the housing is all it would take in the field. If you prepared ahead of time I don't see why it couldn't be done.

The Zuma 125 pump is an entirely different animal than the pump for the WR.

...seem endemic to FI bikes. Noticed this KTM thread while looking for something else:

Not as different as you think. Look at item 13 in the fuel tank schematic located here:

http://www.bikebandit.com/houseofmot...125zl/o/m18967

Looks pretty similar to me with exception of the Zuma pump having a float instead of a simple sensor.

Your top picture is very similar to the silver and black part that can be seen inside the white plastic housing shown in the other photos.

Krabill how about taking your dead pump apart so we can see what the actual pump looks like outside the of the plastic housing.

What size did you use for the front tire? I assume the 5.10x17 is on the back.

I've been running the shinko's for a few rides.. they've worked ok for me. I've got a 4.60 on the front, & a 5.10 on the back.. both 17" X tires.

Here they are in moab this june:


2 of my riding buddies in moab had kenda 270's.

Here's a group pic:


Mine has the windscreen.. i was heading out for the long ride home to Az.

Hey rydnseek ...

Those WR250X's look great with the knobbies !
Are you using the stock wheels ?? Did you have to trim anything to get them to fit and run without rubbing ?? Since you rode that long distance to and from AZ they must work and handle great on the road ..

Great pictures !!

Thanks ...
