When I wanted to weigh my Boss Hog V8 motorcycle, I built a raft and floated it in the pool at the local Days Inn.

Then I loaded my bike on to the raft and measured how much the raft sank.

Then I removed the bike and loaded the raft with M&Ms till the raft displaced the same amount of water.

Then it was a simple task of counting the M&Ms and multiplying that number by the average weight of an M&M.

The nice thing about using M&Ms is that you can use this method year round.  Even in the summer, they won't melt in your hand.

However, if you choose this method, learn from my mistakes.  Don't use regular M&Ms.  Use the ones with peanuts inside.  They are larger so you won't have as many to deal with.

Around here the highway weigh stations have a digital read-out that stays on when the weighmaster is gone.

Wait for a quiet night drive out and park on the pad.

The pad is large enough for the whole bike.  And you can stay on the bike for a total if you like.

I would guess it is pretty accurate...

Not cheaper than me ;D

Buying a track bike (and not just a beaten-on Gixxer or SV), replacing the motor with a fresh 900, trying to rationalize a multi-thousand $$$ CNC milling machine ... and you won't drop $15 on a scale at Target?

My compliments, sir -- seems to me like your priorities are spot on!!!  [clap] [clap] [clap]

Thank you, thank you <bows>

I don't recall mentioning a CNC mill.  I can rationalize anything ;D

But maybe I posted on here about a bridgeport knee mill?  Can't remember.  Still though ;D

Ok, Ill get the damn scale [roll]

The good thing about having 2 scales is you can compare them to each other, then worry about which one is *right*.  ;D

Then when you're pissed at the GF you can swap in the scale that reads a few pounds on the high side.

Every analog bathroom scale I have seen could be adjusted.  So, theoretically you could set the scales to be even.  But then you have to worry about repeatable precision.

I just weighed my M695 using a thin digital bathroom scale:

~ half tank fuel
~ Termi low CF pipes

R = 194lbs = 51.1%
F = 186lbs = 48.9%
Total = 380lbs

Now I'm curious how things distribute with me on there, but I'll need a helper or two for that.

Use a front and a rear stand alternately. . .

Ok, I did not get a second scale.

I weight the 750ss tonight.

354 pounds total (half gallon or so of fuel and no oil, chopped frame)

Just to update with me geared up on the bike (180lbs) and a slightly different fuel load:

R = 308lbs = 54.6%
F = 256lbs = 45.4%
