Decided to do it myself... watched some videos on youtube, looks pretty easy.  [coffee]

Hey, watching Bubba Stewart do a triple at a SX looks pretty easy too.  [laugh]

Seriously, have someone who *knows* how to change a tire by hand show/help you.
And by *knows* I mean someone who's done way more than one or two tires.
It's 90% technique.

hehe.. i just think the love for your bike, gives you patience and will to do anything...  :)


just came back from coffee , was talking to one of my friends abt it .. he told me that the balancing by hand is not going to be accurate bcoz he thinks
the balancing machine they have in the shop spins the wheel faster than hand or smth like that .. is balancing my hand using this : http://www.amazon.com/gp/product/images/B0040HE8OS/ref=dp_image_0?ie=UTF8&n=15684181&s=automotive and this technique How to Balance a Motorcycle Wheel is going to be good enough????
and he also said that if you change from 1 brand to another (in this case im going from Dunlops to Michelins) ... the balancing should be done differently..

The balencer in the video is a static wheel balancer.  Wheel speed itself has little to do with how to balance a wheel.  There are two wheel balance issues.  One is static imbalance, which is imbalance in the axial plane (heavy on the top or bottom) and causes the wheel to bounce up and down.  The other is dynamic imbalance, which is imbalance in the radial plane and causes the wheel to move from side to side.  In your car static imbalace is usually felt as a rapid up and down movement at the steering wheel, usually at about 55MPH.  Dynamic imbalance is usually felt as a side to side movement at the steering wheel at a somewhat slower  speed. 

Modern "spin balancers" calculate both static and dynamic imbalance and tell you where to put the weights to compensate for both.  The balancer you are looking at is a static balancer, definitely good enough for the narrow front wheel.  Since race teams use static balancers, I think it is safe enough to assume it is good enough for the rear wheel too.  One trick is to split the weight between both sides of the wheel.

For balancing I'm trying the Dyna bead coolaid, installed in my Pilot Powers 2CT's last weekend.

I'll post my impressions but I won't be riding for another month possibly.

I sprung for a Cycle Hill changer with a No-Mar bar, pretty pleased with it. I figure on 3, maybe 4
tires changed per year. Plus a few buddies tires will mean free beer.

Hey good luck if you invent a new technique! Let us know how it works out!

After reading this post and thinking back on my tire changes.  I think I'm gonna spend the money on the Cycle hill changer as well.  It'd be nice to not  wrestle with a tire on the ground and to never contribute to my local tire shop's weed habit again.  Takes em 6 hours to change a tire, and they say "dude" a lot, so I'm just filling in the blanks.   [cheeky]

Jarvicious

I agree with He Man.  While I may pick up a balancer eventually ($50 is nothing by comparison to the rest of the bullshit I spend money on :)) I threw a tire on, torqued the wheel and put 600 high speed miles on it before I picked up a nail.  Took it to my shop to have patched from the inside and when I got it back, my tech said that he went ahead and balanced it again because it was sooooo far out of whack.  I never even noticed.  The bike ran better than before actually (Diablo to Pilot Power 2CT). 

Modern wheel/tire technology is worlds better than it was even ten years ago.  I'm not saying I'm going to install a tire and instantly hit the slab and punch it to find out if it's balanced, but give it a time or two and you'll have the change down to an hour or two max, with or without balancing. 

That being said, breaking the bead and removing the tire is nothing.  That's the easy part, but the one piece of advice I'll give in regards to chucking that thing back on is that whenever you've got the one side of the tire on and are working on getting that last little bit of bead around the rim, push the opposing side of the bead  (the part of the tire that already has both sides of the bead within the rim) as faaaaar towards the center of the rim as you can to give the rest of the bead that little extra slack.

I'd also give yourself at least 3 hours to do the change, which includes spare time for cursing, rubbing bruised knuckles, and grumbling under your breath while staring at your tire changer and drinking beer.  You'll need it.

If you live near a Cycle Gear and can mount your own tires, they will balance them for free. It's company policy.

It's not too hard.  Lots of lube, good tools.  As mentioned, the warmer the tires, the better.

What Jarivcious said, good advise there.

Yup, keep the opposite side in the deepest part of the rim and it will be much easier.  I've made a few changes using only tire irons, a Wonderbar, and a couple rim savers.  The rim savers are very useful.  I've got black Monster Dark rims, and I really value keeping the paint on them and the rim savers help a lot.

I should be posting some images & commentary from my latest tire change within a few days.

He Man

^^ jarvicious mentioned something that people just dont do even though its common sense.

once u break the bead, when you push and deform the tire on one side, it gives you more room to work with on the other, I always do 2 man tire changes. Just makes life easier. Once you get one edge off that stays off, just pull on it with your hand and it will come loose.


I know this may sound stupid obvious, but you might not think of it, but the WHEEL IS SMALLER THAN THE RIM!!!! Just remember that!
