We need way more help then just parts and a gym.
I carried a metal rod in my tool box marked for your 4 lap moto or ten minutes ,regional moto,and Loretta moto.
Putting just enuff fuel in to get thru the moto is a mod that cost nothing
But,Cheng shin used to make tires so light you could flat setting the bike off the stand
Heavier tires would lower weight distribution and aid bike handling
I don't obsess over weight however I did try a Bridgestone X30 and it was noticeably heavier just carrying it around which has caused me to not buy it again.
If you happen to have some tire weights, please share.

I always laughed when I saw guys topping off a tank for a 4 lap moto.
Cut all the knobs off and fill er up with helium,then you could drink 3 more beers and weigh the same
The weight of your wheel assembly matters. It matters to acceleration, braking, and suspension action. That's why mountain bike racers use carbon wheels and tubeless setups, why the MX race teams shave grams off their hubs, spokes and bolts when they can, and why factory guys always seem to get holeshots. It's not always the most powerful bike that wins a drag race; it's usually the bike with the best net power to weight ratio.
"This bike is too heavy, I need lighter tires..."
Comedy gold I tell ya!!
