I did some digging to answer my own question...
On Ebay, I found an ad for an XG750 engine. Strapped to a pallet & wrapped in plastic, the shipping weight was 178lbs. A google search showed those pallets weighing between 33-48 lbs. The pallet in the ad was on the heavy side with particle board nailed to both sides & supports for the engine. I estimated the pallet & wrappings to be (roughly) 42 lbs.
The shipping weight minus the estimated pallet weight yields an estimated engine weight of:
136lbs +/- 5lbs
The engine in the ad did NOT include: exhaust, intake parts, starter, or ignition parts. Draw your own conclusions for a total weight.

Where does all the weight come from?
Steel Frame, steel forks, steel swing arm, dual shocks, huge ugly exhaust system, It all adds up.

My 1986 Yamaha SRX600 is just as above and weighs 361 pounds wet.

I had to google a SRX600, everything on that bike looks appropriately sized and designed with purpose. Nothing bulkier than it needs to be (it makes a nice looking bike too). Our Street Rods... built like a truck!
I've been researching powerplants to use for a light-sport aircraft or kit plane build & the 750 is a front-runner currently. Good weight, good power, fuel injected, water cooled, compact, smooth running with the balance shaft, easy to work on, & cheap!

This bike (#238) was purchased March 10, 1987 from Don George’s Sports Center in Clarence, NY (near Buffalo) for $2,160 ($4,870 in 2019 dollars). Most all parts on the bike are genuine Yamaha and period-correct. This bike has been modified as follows:
- Stock airbox removed to fit dual-tuned intake system 1
- Intake runners tuned to 2nd, 3rd, and 4th harmonics 2
- Stock 27mm carbs with Dynojet Stage 3 jetting
- Stock muffler replaced with SuperTrapp slip-on
- 27 pounds of parts and pieces removed
- Small lightweight 3.3 AH SLA battery
- Progressive Suspension fork springs
- Proper Static Sag and Race Sag
- Larger front counter sprocket
- Triple-Disc brakes are stock
- DeCarbon shocks are stock
- K&N crankcase breather
- K&N pod intake filters
- Weighs 361 pounds
1 Primary side is smaller/longer and secondary side is bigger/shorter
2 This intake system is designed and tuned to enhance power from 3,500 RPM to 7,000 RPM. 2nd harmonic tuning results in 10% pulse strength and up to +4 PSIG on the intake side. The effect is the same as a small supercharger/turbocharger over narrow RPM range. For this system 2nd harmonic occurs between 5,700 and 7,100 RPM.
