A question to the RZ350 folks in the room.
Whats the full up weight of the 350 motor?
And I know folks have discussed it before, but any guesses as to the full dressed 500 lumps weight?
RZ350 full dressed engine weight vs RZ500 engine weight.

Re: RZ350 full dressed engine weight vs RZ500 engine weight.
When I shipped my RZ500 engine back east, it was very near the FedEx 150 pound limit. It was complete minus the carburetors and associated fuel lines of course. I believe I had the stator cover removed also. So maybe 140 pounds minus the wood crate.
I have not weighed an RZ350 engine.

One source, gomog.com lists a 350 YPVS as 77 lbs. After hefting my lump around, seems about right.

That seems right. My number is 75 pounds. I've owned many. I've shipped a few. Easy to manage.
The 500 motor weighs a ton and a half. Every time I try to move one I feel 10 years older.

Wow - less than half the weight and 90hp+ potential with big bore/stroker setups.
Can't wait to see unusable the 1RK hybrid will be - although from what I understand, anything outside drag racing short runs cooling is the big concern for over sized 350 motors.

That motor would be nowhere near 75 lbs. Far from it.RC45 wrote:Wow - less than half the weight and 90hp+ potential with big bore/stroker setups.
They run hot stock and more so in even slightly modified form and benefit from the addition of a cooling fan. Highly modified motors as you mention would most likely be running electric water pumps and massive radiators.

Re: RZ350 full dressed engine weight vs RZ500 engine weight.
Maybe I should not say it too loud here... but the RD500 engine is not a sport bike engine in my eyes.
I think you will get the same power out of 250cc if you want (Honda RS250 - 92hp, total bike weight 101kg - ok... this is a production racer).
That`s why I`m not interested in tuning of my RD500 - it`s a nice piece of engineering but nothing more.
