Liters
Originally posted by Steve View PostOK, continue on with your math, if you want to correct somebody.
There are 3.78541 liters per gallon.
Divide that into the 6.1 pounds per gallon, you will see that each liter weighs 1.61145 pounds.
Since we are getting more technical, let's also get precise.
That gallon of gas is actually 6.073 pounds. Divide that into liters, each liter weighs 1.60432 pounds.
In other words, you are both correct, but you were thinking he was wrong.

I was having second thoughts on 630 vs 530 vs 520 chains, I was thinking maybe a 520 chain might be a good idea (aside from shorter sprocket life on our heavy bikes especially with a hot rodded engine)
I'm wanting to keep my tire options open in case I decide to ditch the 5,000 mile super sticky tread on the awesome $77 140/70 (5.5" wide) Shinko SR741 in favor of a 10,000 mile tread $115 Avon AM26 RoadRider in a 150/70 (6" wide).
It may be nice to have it already set up with a 520 and maybe 1/8" spacers behind the sprockets in case I wanted to go for the 150 ever, and would certainly benefit weight savings. I have yet to price 520's that are equipped for a 480 lb bike with full tank and 150 lb rider, and being propelled by a hot rodded 920cc GS engine with mega-traction in the rear... $$$$$????'77 GS750 920cc heavily modded

Holding a hefty stock GS cast steel footpeg in my hand (guessing 3 lbs/pair, looking at fleabay at really nice 99-07 Hayabusa rearsets for $30 per side... I bet they will weigh half as much installed, plus I can actually shave down a lot of the bulk off of the frame in that area down to just the cradle tube, and weld on a flat plate for each mounting bolt, or maybe a a threaded sleeve welded to the frame cradle tube (much stiffer!). I'm gonna say 3 lbs weight savings in addition to chopping the entire rear passenger footpeg frame assemblies off, about 7.5+ lbs total I am guessing? I would be chopping the extra top parts off of the 'busa rearset mounting place, not sure of mounting the brake master cyl to the frame or the rearset. Hmmm?

there are a few members here, including me that have fitted GSXR complete footrests. yes they are a lot lighter and work really well. i cut off all existing mounts and welded on new plates to fit mine whereas some have made up mounting brackets that use original mounts.

How is the riding position with your feet 5" back from stock? I feel like your seat would be much more comfortable with a forward slope. Those are some sharp rearset brackets, they look super high dollar! I think I may consider mounting them more forward and slightly lower, so that the top mount bolt is in the crotch of the frame gusset where the swinger pivot is, just below and to the rear of the swing arm pivot bolt. Slightly higher than stock but to not interfere with the kickstarter.
Can we see a larger picture of your brake side rearset?'77 GS750 920cc heavily modded

what's with the polished aluminum non-remote rear brake master cylinder reservoir??? I tried searching ebay for GSXR750WP rearsets, and nothing came up with the WP on the end, and none of the other GSXR rearsets had that reservoir setup!'77 GS750 920cc heavily modded
