    Hi all, I've redesigned the luggage rack for the WR250, and am offering it in black powdercoat now, along with the brake parts protectors and skidplate. Here's a pic of a set of black parts I made for a WR250X.
    Thanks! http://www.bandbmoto.com/

    Trust me. The Japanese are trying to cover their own asses on their home market first. We will probably get the recall in about 2012 when most of the 08-09's sold have been replaced at owner expense.
    They do not want to eat this whole mess at their expense. For everybody who replaces their own fuel pump they might get something like a $25 gift card toward yamaha accessories:evil and a customer loyalty survey.

    Those that want to carry a spare pump, but are worried about the size and fragility of the whole assembly, could just remove the pump from the assembly like the picture above. 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.

    There have been responses to this quote. I personally would not use carbon fiber material or any composite for a heat shield. You will find that the high temperatures will toast the epoxy resin in the material at about 450 to 500 degrees.:baldy It may look ok on the "cool" surface side, but will be compromised. This is especially true if it supposed to be a structural part, ie a rock shield. The material will not have the original structural properties.

    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). :clap

    I just got the Shinko 244's mounted up on my WRX. Good looking tires. :clapI 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. :eek1 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...

    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.
