About how much would a Honda CBR 300 engine weigh?

I'm looking for a suitable engine for an APU (auxiliary power unit) for an EV (electric vehicle) range extender. I've came across some wrecked CBR 300's for cheap and they seem to be just what I'm looking for. I take it the engine and transmission are one unit which is ok. But about how much would one weigh? I'm looking for something that's light, low emissions, and with close to 20hp/15kW continuous power.

Thanks! About how much would a Honda CBR 300 engine weigh - 1

Tire changing without lever?

I have a 2003 honda xr100r. Its in pretty good shape but over the winter the tire became flat. I pumped it multiple times but it didn't work so i removed the tire from the bike to change. However, I do not own tire levers. Is there any way i can remove the tire without the lever? (its the front tire).

APPROXIMATELY how much does motorcycle insurance cost in michigan?

I was thinking of getting a dual sport bike, specifically a used honda 250 or something similar. I just can't seem to find a good clear answer on insurance prices. I'm 22 have 0 accidents 0 tickets 0 anything really and it wouldnt be my DD. Just something street legal to get me to the trails as i don't own truck and really have no desire to as i have a long commute and my car gets over 40 MPG. I drive almost 20,000 miles a year so i'm not getting a truck just to haul a toy and i know insurance on a truck will be more than on a bike lol.

i'm not looking for an exact number, people alwasy assume i want a solid number and say 'omg how are we supposed to know?111!1 it varies! I'm just looking for a rough ballpark. What do you pay?
