    Rim Lock Placement

    Rim Lock Placement

    Eh, I'll take your word for it. I have basic body of the rim lock already cut.

    Rim Lock Placement

    Funny you mention the screws; I've been toying with that option as It seems like they might be easier to deal with on the trail. I have a Sun 17x3.5 on the rear of my DR and I've had to make a rim lock for it (although not done yet). Either way I'm gonna point a drill bit at my pretty Sun rim. Perhaps the screws will be less hassle in the end. Highmarker: I'm not familiar with the terms "j rims" and "e rims"; could you explain?

    Rim Lock Placement

    That's what I was thinking, and I don't mind balancing the wheel; I've never seen it directly opposite which always seemed counter intuitive to me. I thought maybe someone might have an opinion or industry knowledge that advocates it be closer to the valve stem for reasons better than balance (keeping the bead stable closer to the stem, etc)

    Cush Hub Issue

    I think we're both talking about the same thing. I was referring to the sprocket hub as the "carrier". The spacer is typically sitting inside the sprocket hub's bearing allowing the float. I'm surprised to not see one in the pictures.

    Cush Hub Issue

    do all three bearings have an identical I.D? All of the cush drives I've dealt with have a carrier bearing with a larger I.D. and a spacer to separate the carrier from the hub and also center the carrier on the axle.
  7. Every wheel with a rim lock I can remember seeing has had it placed to one side or the other from being diametrically opposed to the valve stem. Is there a reason for a location as such? I have a DR650 which does not have wheels drilled for a rim lock and I intend to install some. I'm just curious if there is a particular spot that is optimal.
  8. The DR650 is a solid choice. Mine has yet to let me down. The seat sux, but I fixed that with a Procycle unit. The other major item I put on it is an Acerbis 5.3 gal tank. Those two items will make you a fine ADV tourer.

    Do all rims match all hubs?

    My experience has been that with 17s you *can* lace a given rim to a hub but as mentioned, the angles may be off. For example, I laced a Behr 17x3.5 that was once on a Talon hub on the front of my YZ, to the rear Talon hub (from the same set) for use on my XS650. The angles are slightly off - enough to notice if you look. I rode the bike on Buttonwillow for a day and didn't have any problems with the spokes at an odd angle. Doesn't mean it's necessarily ok, I just got away with it. I've got a similar thing going on right now with the rear rim I've mounted on my DR. On larger rims, it hasn't been much of an issue. I've laced a 19" rear rim onto the front hub of a YZ125 and didn't notice any issues with the spoke angle as it left the nipple. Perhaps the hub diameter is close enough front to rear, or the longer spoke shows less misalignment. If you're buying rims, I recommend ordering them for the end of the bike you're putting it on. To answer your question directly, I don't believe they do. If they do, consider it a happy coincidence.

    Hot rods crank kits

    I've used the entire assemblies and rebuilt stock cranks with their rods. I've either been doing it right or have gotten lucky. All told, at least a half-dozen of the assemblies and a bunch of rods for rebuilds. Some for my bikes, some for customers. No failures I'm aware of. The only thing I can pick at is that I do check the new assemblies for runout. Some have been dead on, and some haven't but were still within the tolerance called out in the book. I straightened out any of the ones that were out to dead-nuts or as close as I could get. Things do change though, so it's possible quality could be slipping. I don't think I've done a bottom end for 8 years.

    General Air box mod

    Just out of curiosity, in regard to reckoning the intake hole vis a vis piston size, how might the formula change if one has a twin cylinder; more precisely, a parallel twin where the pistons rise and fall together, but only one is pulling air on a given rotation? Same deal - one piston's area? Double that? 1.5X piston area? Just has me wondering about my XS650. I have lots of room for a custom airbox, but it may not be so necessary on pavement (for the sake of dirt, etc.) - goes fast enough now.

    What innertubes do you use?

    Ugh; during the building boom out here in the AV back in the 2000s, there were nails all over the road. Often seemed to be in intersections where a box would likely fall off of a truck pulling away from a stop sign.

    What innertubes do you use?

    When I began riding my YZ250 in flat track trim on supermoto tracks, I was experimenting with tire pressures that were too low to responsibly post on a forum. This was with my cheap IRC tubes I was buying from a chopper shop. The tires got hot, but they didn't go flat. With proper supermoto wheels/tires I ran the same pressures you are and all was fine except for the one flat mentioned a while back. This was in the SoCal desert with sharp edged rocks and all the other crap out here. I always applied baby powder liberally and if I did use any lube, it was the vegetable based lube I got with my No-Mar tire changer. If you're using something like dish soap, it could very well be drying them out and causing these mystery flats. I would be astonished if the mechanics you're dubious of would be able to pinch the tube and it would still hold air...for a while. I'm with the dudes who are suspecting you've got some spoke ends poking the tube, or perhaps a chewed up wheel/stem hole.

    Head Shake ktm 525

    Tire balancing, fork health, and even the aerodynamics are good suggestions, however, be sure your shock isn't tired as well; whether a supermoto or a roadrace bike, you'll get tank slappers if the charge is low on the shock. I had an 05 SMR 525 and didn't have any wobbles. While it had the adjustable offset trees, I never messed with them.

    Motard using Dirt tyre hub.

    I dunno one way or the other, like I said (or implied); I just sorta assumed it was for the transmission. Triumph used bumpers in their clutch baskets at least as far back as 1959. I guess it would be worthwhile to know if the OP was asking in reference to cush drive or quality of the stock hubs...before we get off topic arguing cush drive,
