Motorcycle Wheel Balancer

[jono49]

I used to get my Bike tyres fitted at bike dealerships, and Tyre fitting centres, Until one day I got a rear fitted to my old Kwaker ZR7, The guy that fitted it said he had no balancer but he would improvise.....He used two trolley jacks at full hieght with a 12mm round bar through the wheel and supported on the Jacks.........So i thought if it's that simple I'll Make one but a little bit Posher..But only!!!! just knocked this up in an hour one Quiet nightshift and I've never had a comeback yet from any of my mates ( Surprising how many you can aquire when the word gets out) The principal is The out of balance bit (The heavy bit) will settle at the bottom when it stops, Mark opposite for reference then take it to quarter past and let it settle again and see how fast it drops! then guess a weight ie: 10grams repeat and add weight where you've marked until it stops wanting to fall and stops still ( Use insulation tape to hold the weights on until your satisfied it's right)....I think thats the easiest way to explain!

Nice idea if a bit crude but there's no way of testing the dynamic imbalance, is that not an issue on bike tyres?

Your wheel bearings are not good enough with the seals in to allow for proper balancing. Make an "A" arrangement with two bearings without the seals at the end of each upright and run your spindle over them. I'll post a pic up when I have done a bit more decorating in the lounge!

Simmilar to the one i use, though mine includes cones and bearings,

rarely do I ever do the rear though, never found that it makes any difference

Balance

Yes your right Jim the rear was photographed on there but it was spot on with the old weights
"Wozaaah" This method was used before the dynamic machines were invented...But I know where you are coming from, but I can vouch for the front being ok to *68mph
RichardM Yes I've had this with an R1 front and the bearings were tight on the seals but I still managed to get it Spot on despite this and the owner really rides the Bike!
Oh and the guy at the tyre place who made it look so simple fits Motorcycle and Sidecar outfit Tyres at most Cicuits in britain and the IOM and the NW200

The one at the shop has cones that push into the wheel centre and lock there and the spindle rests on two bearings at each end and it is very accurate. Static balancing is fine.

Simple static balancer's like that are used a lot to balance aircraft props, so if it's good enough for an aircraft it's good enough for a bike. The ones i have seen used on props are are no more complex than in the pic.


Very simple, but very effective................ more importantly cheap and does the job admirably.

Well done.



Kind regards,

Good bit of kit that I made a similar one. You should balance your rear tyre
as well as the front if only to reduce wear and tear on the shock absorber.

just jack the front wheel of the ground and spin it on its own axle and bearings to balance thats all i do
