    Depends on the wheel, width, hub type etc. if an SM rim is not offset properly it will rub assuming you are running wide rubber. Mine is offset to fit the 150

    I'm looking for stock 2.15 rear rim and stock hub offset, S model. I don't need to offset for chain rub.

    I have a couple sets of S wheels.
    I can go lay a steel rule across the sprocket and measure down to the edge of the rim. Will that tell you what you need?

    A few years ago I installed the 12 O'clock Labs edge tail light upgrade and noticed that their signals in the tail light ran out of sync. I emailed them and they sent me a set of those (pre-production model). To get the lights in sync they are ON all the time and turn off with the flash signal. Simple yet effective. They really do increase visibility on the DRZ and I highly recommend them. The guys at 12 O'Clock are awesome to deal with :thumb

    OK, I went out and measured my S. One set of wheels is on the bike and one set is not.
    On the left side of the swingarm it measures 2.5 inches from the inside of the swingarm to the edge of the rim. My other set of wheels measured 2.350 inches from the outside surface of the sprocket to the edge of the rim.
    Hope this helps.

    Thanks a lot :D If I could ask one more huge favor, if you could also measure from the rotor side on both sets of wheels.

    On the right side it measures 2.25" from the inside of the swingarm to the edge of the rim. The other set measures 1.35" from the outer surface of the rotor to the edge of the rim.
    Disclaimer: The wheel that is not on the bike may or may not be true. I never checked it. The wheel on the bike is true.

    Yep, I want all the help I can get in sand (plus fully loaded). The Pirelli MT21 140/80 seems like an option?

    Thanks Numbers, useful feedback
    Eddy, that Kenda looks nice. I need have a fairly long trip planned, so (perhaps wrongly) I'm figuring the less aggressive MT will last a few more miles.

    Apologies everyone for talking tyres :D
    Cheers

    Nothing generally goes wrong with the seat, so you should be able to just replace the needle and o-ring.

    So, a friend brought me a dr-z he bought cheap with a blown engine..

    I open up and I find this:


    <a href="http://www.flickr.com/photos/35291439@N07/8514574969/" title="IMG_4344 by okipouros, on Flickr"><img src="http://farm9.staticflickr.com/8229/8514574969_9591ef8c06.jpg" width="500" height="375" alt="IMG_4344"></a>

    Also the cams and head had signs of severe lack of lubrication, so then i found this:


    <a href="http://www.flickr.com/photos/35291439@N07/8515678390/" title="IMG_4337 by okipouros, on Flickr"><img src="http://farm9.staticflickr.com/8511/8515678390_983577a3e7.jpg" width="500" height="375" alt="IMG_4337"></a>

    And I noticed the following issues:

    - Its plastic and cooked in oil
    - Its drafted (see picture below) due to injection molded manufacturing process, so the the load is not shared equally
    - Being plastic, it can have manufacturing faults such as material impurities, bad process which can cause a number of problems that lead to an early failure


    <a href="http://www.flickr.com/photos/35291439@N07/8514565295/" title="IMG_4340 by okipouros, on Flickr"><img src="http://farm9.staticflickr.com/8370/8514565295_10e0fcee9e.jpg" width="500" height="375" alt="IMG_4340"></a>

    So I got one made from steel, which will last forever.

    Machined in molybdenium steel alloy used for gears by a specialist shop that only does gears

    Tried it, and it feels like there is much less friction compared to the plastic one, and that it meshes smoother



    Also thinking of adding 5 holes to ligthen it up, machine shop told me its $6 extra, and can be done if needed, personally, I dont think it will make a difference, cause there are much heavier things in there, with even larger moment of inertia to lighten up

    If people are interested I can get some made, but the bigger the order the lower the cost, so let me know if you are interested

    Cost is estimated at €42/£37/$55 +p&p (about $5 extra)

    That shouldn't matter, as the float valve should still prevent overflowing.

    just did a 1600 km trip over various surfaces on a rear Kenda 760 11 . I liked it. about 1/2 worn out, but there was a few hours of high speed sealed roads included in the trip.

    I agree but it seems every parts source only sells them as a set. The o-ring should be easy to find. Do you know where to get just the needle?

    Theyre plastic for a reason, or do you honestly think suzuki just got lazy and said, hey lets just make some of the gears plastic.
    Fyi its not a load bearing gear, it just spins a pump.
    If the pump fails it breaks a plastic gear, if the pump fails (or the gear fails)and the plastic gear dosent break you wont know it until your engine seizes. But good luck with your revelation...

    Head on over to thumpertalk youll make billions and that will be the latest and greatest "must do, or babies will spontaneously combust" fixe.
