I weighed Blanca this morning by a couple diff methods.
Would like to throw these out and hear your ops on them.
1st.
2009 Hayabusa.
Brocks full 4into1 exhaust(supposed to weigh 8lbs, but on scale at shop was closer to 9 but ok)
Marchesini Forged Magnesium wheels with Michelin HPX tires. (savings of approx 7lbs over oem) https://www.hayabusa.org/forum/gen-ii-busa-information/121272-blancas-new-shoes.html
Relocated regulator and removed belly pan and bracket (1-2 lbs savings)
Removed rear fender and made simple tag bracket (1-2 lbs savings)
With 108 miles gone on tank which I know by exp will be 4 gallons back in to fill it would leave approx 1.5-2 gallons in tank.
I have one scale. A digital bathroom scale. Before anyone doubts its accuracy. My wife usually travels. We use it to get to the 65lbs bag limit .
I weigh myself, then hold bag and subtract. Its right on.
I have 5lb certified postal block I use for mailing. Scale says 4.8-4.9lbs every time.
With both feet evenly spread as compared to just the ball of one foot it is within .5lbs. So it is not sensitive to whether load is properly spread or in a single point. I will elaborate in a bit.
Now the methods:
First method I simply rolled front wheel onto scale while rear was still on ground. Then took reading. Then rolled rear wheel onto scale while front was still on ground. The took a reading.
results : 266 lbs on the front
248 lbs on the rear
total of 514 lbs total..
Ok so you say bike should be level or I should use 2 scales.
If bike is and was level in 2nd method but still I use one scale is it not the same just more work ? See pics.
Second method
Put bike on both stands as seen.
bike is level as seen by level on bike.
Place scale under front wheel and slowly lower it onto scale. ZERO weight held by stand and take a reading. Lift it back up onto stand.
Place scale under rear wheel and slowly lower it onto scale. ZERO weight held by stand and take a reading.
results of 2nd method : 257.5 lbs on front
241.5 lbs on rear
total of 499 lbs
Now when I use the stands I notice obv that when one end is down it seems to be jacking more weight onto that end.
So you would think if its not level and this theory is correct the weight figures would be higher than they should be.
To test this I used 2-3 hard books to spread out weight of tire for anyone who thinks that just the contact patch of tire was not reading correct as well as make sure that even when one end was down with other end still sat level.
Same readings as 2nd method..
So I ask which if either method do you think is fairly accurate .
Rolling onto scale one at a time for a total of 514lbs
or using stands and letting one down at a time for a total of 499lbs
I am leaning toward 2nd method as it seemed more exact ?
???
See a lot of threads about supposed weight but cant find one where anyone actually weighed their bike on certifed scale with both wheels on like at a dump or truck stop ?
