    Just a couple thoughts on balancing your own self, can anyone accurately measure the inside diameter of a front and rear wheel bearing for the 990 and post here please? With that said, would a steel round bar in above diameters work for balancing at home? the bearings on the wheel would act as, um, bearings, I think. Also makes me wonder if pushing off some of the brake fluid pressure from the caliper or removing the brake pads (also chain for rear), to let the wheel spin freely, cant they be balanced right on the bike providing the wheel bearings are in good shape? :ear

    The bearings on the bike have to much drag to really let you do a good job balancing

    crofrog is absolutely correct. It'd take a significant amount of imbalance to get the wheel to move when using its regular bearings.

    You can get a decent motorcycle wheel/tire balancing setup for about $35 on amazon. it includes a straight steel rod, 2 conical adapters to make that rod work with most wheel bearing sizes, and 2 "feet" with MUCH freer spinning bearings than what is already on the wheels for that rod to turn in.

    I had to cut the small end off one of the cones because our front wheel hub is so narrow the cones were touching before being tight against the bearing.. but otherwise the setup worked great. I could be pretty repeatable with only a 2.5gram change in balancing weight.

    I use lead strips under the rim tape I think it was 75grams for the motion pro lite lock ,

    I don't balance tyres just the rim / rim lock . Makes a big difference , and placing the lead under the rim tape mavens you never have to worry about it getting knocked off or coming off in a river crossing

    I do a quick gravity balance on all of my bikes. Without a balancing stand, just remove the outer spacers to reduce friction.

    I got tired of buying the stick on weights, and I'm a big believer in recycling, so I make my own.

    Just make a rectangular form from heavy duty foil, melt some lead in an old tin can with a propane torch, and pour into the mold to about 1/4" thick. Score every 1/2" with a chisel. Break off the amounts you need & stick in place with RTV.

    that's what I did at first.. 1/2in rod and aluminum machined spacers on my lathe. rolling over two sealed bearing resting on two jack stands. works excellent.

    now I've got a No Mar balancer and Snap-on static balancer. a bit more refined, but works no better than the home made version.

    key is watching video below... shows you a very precise way to balance

    Wouldn't it be easier just to put new double stick tape on the weights you already have?

    Sometimes I do that. Most of the time I found the tape doesn't hold well to old weights. I usually supplement the tape with RTV anyway. I'm of the opinion that my bikes are never going to win a beauty contest, so I pick durability over aesthetics any day.

    FYI, my wife is the one who pioneered the process for making your own lead strips. We pick up old lead weights from car tires any time we see they laying around. A good source is the parking lot at the tire store. On a hot day you can pry the old weights out of the asphalt.

    I have seen this guy duct tape the sole on his boots and ride for 5 days like that....and now I know why my truck wheels were out of balance on the way home from Spodefest.:D

    I am just using spoke weights at this point.

    Happy Holidays Jeff...

    just ask the tire store for used weights. most times they will sell for low costs and/or just give em to ya. got a couple 5 gallon buckets full of old weights for casting bullets.

    for motorcycle been using stick-on weight, lead solder wrapped around spokes and OEM weights that anchors on spoke nipples.

    Not me with the duct taped boots, but I think I know who you are referring to. You have quite the memory.

    Spoke weights.... Hmmmm..... I think I could easily make a form to build those. Conical.... Drill & counterbore a hole down the middle. Slit with a hacksaw. Winter is here & idle hands need projects.

    It's getting harder to find lead weights for environmental reasons. The least expensive material I could find new was the biggest fishing weights. It won't be long before those are also outlawed.d

    I just use goof-off to remove the old adhesive and lay the old weights on a bit of 1/4" 3M automotive trim tape. Bought a roll several years ago, one will just about last forever doing an inch at a time. Been on the same little square of tire weights for years this way. Stuff just has to be clean to stick. RuGlide, oil whatever will prevent the adhesive from working. Goof-off is your friend.:freaky

    You are right....It was John Arnett with the boots.....it was you that wished he had duct taped the door shut on the trailer to avoid people with cameras invading during those private moments we all have.:rofl
