Topic: New Member...Question about Weight Savings

[ProTeal55]

Now that my bike is pretty much done ( 4 Now) , I think I am gonna lean towards making it
as light as possibile. I need to weigh it now and see how much I have seved thus far, then see what else I can remove.

I know this has been asked b4 but what does a CB750 weight in at in stock form "wet" ?

Shop manual for the early K's lists curb weight at 517.3 lbs.

Drilled the rotors for the "two Halves" cafe project and lopped 1 lb off each one

2 pounds off the front wheel aint bad

That's pretty impressive!  Were you running helium in the tires?

No, it was suspended from the workshop roof, just hovering over the scales.

When an expert bike mechanic/builder/engineer/scientist or whatever the proper nomenclature is these days builds a CR750 with the express design intent to make it as light as possible and gets it 4 pounds below 400, I stand by my earlier statement that a mere mortal is unlikely to make the same target.  I have NO experience to back up my statement - it was purely a gut feel, and it turns out I was pretty darn right that it's near impossible to make a 750 weigh less than 400 pounds.

So piss on my parade or in my cornflakes all you like 

Tintin, I am a much lesser mere mortal than you are and it dose weigh what it weighs and it could have been lighter had Chris requested it.
So if you call me a nomenclature again I will send Chris round to piss on your cornflakes, he's a very big guy

You can also have them turned down but don't over do it.
Have just one disc, save the weight of the other.

Lots of places to drill some "speed holes" under the tank, around the coils , etc..

Well I weighed my racer project today, and I'm happy to report that it's well under 300 pounds! I can hardly wait until I get the engine in it, man that thing is gonna fly!

Terry,

Is that 300 without the engine?

[Terry in Australia]

Well, duh, that thing weighs a ton!

What a concept!  You'll really get great mileage too.

I don't have any experience with this modification but it looks like it will save some weight.

Hey tahnks for the link mate, I just scored another ARD magneto for another project bike (1166cc "K1 Kruiser") while my endurance racer project will be running a dead-loss system for lighting, the "Kruiser" will see more commuting duties, so will need an alternator. Cheers, Terry.
