Title: S40 engine swap
Post by dustin1455 on 04/07/15 at 16:04:41

has anyone ever put an engine from another motorcycle onto a savage? i am interested in doing the cafe kit from ryca but i am a bit skeptical about the performance capabilities of the s40.
has anyone ever looked into doing this? what kind of difficulties may arise or what kind on mods may have to be done to the newer engine or the frame to make it work. any feedback will be helpful.

thx. :) :)

with a stronger engine you need stronger brakes, stronger suspension, and a stronger frame, all of which you can get, more easily and less expensively, by starting with a faster bike
You can do anything, anything at all, with enough money and skill, the question is, is it worth it?

I have a Cafe with a modified Savage upgrade (piston, cam, carb, some head work). It will make it to 100 mph if I ask it nicely. The Savage frame and handling really wouldn't be able to handle much of an increase in horsepower.

It is fun bike....but doesn't handle like a sport bike.

I like the idea of a GS500 twin in a Savage Frame . Vertically I'm sure there is room and the crank case's are about the same size ??? But I don't have a GS500 engine --- yet . ::)

Ride of a Savage and power curve of a 500 twin ! :o

why yes, Shawn, yes you do
Are you connected to Ryca, or just a fan?

I'm sure you could shove all sorts of engines into the ryca. Wouldn't be any worse framewise than those old over powered under framed UJMs from the 70s and the brakes,while not amazing, get the job done. I kinda like the giant single tho....
A brit twin would look nice in there but no real performance gain,just pain.
How about a modern Bonneville engine? That will get you noticed.

I was thinking that you could find a crashed out Hayabusa cheap and swap out the engines.

I think that bike looks nice enough that you should just leave the motor right where it belongs! The GS500 will outhandle and outbrake the Savage any day of the week.

Go find a crappier donor bike.

Not sure which UJMs you're referencing, but all the ones I've ridden would smoke a Savage in the twisties; CB 750 four, 750 nighthawk, Z-1, current XS1100 (a touring bike no less) adding power would make that worse, without upgrades. and a brake setup that's 'adequate' for a 30 horse engine is not, for a 60 horse engine

And a 'Busa engine? total death trap

Yeah I was trying to point out that UJM's in the 70's had stonking engines but the frames were a bit weedy (hello Rickman, Seely etc) and the brakes were not as effective as on a modern bike. Nevertheless, People managed and a good time was had on them. So, following that line of thought, I don't see any problem putting a more powerful engine into a Savage so long as the builder/rider knows what they're getting themselves into and ride accordingly. People on this forum are building bigger engines, hotter cams etc and putting blowers on their bikes to power up the savage donk so I don't see what problem there is swapping to a more powerful engine, if that's what an owner wants. Good luck I say. A 'busa engine tho, I agree that's just silly. Only UJM's I ever owned were a CB750 and a Suzuki GS 750. Both were really nice motorbikes.

you have a good point there
when someone brings up engine swaps, though I assume, maybe wrongly, they're talking a LOT more powerful engine
of course souping up a savage motor doesn't add a ton of power, but I could see swapping in, say, a DR 650, which is significantly stronger but not ridiculously so
I also assume they want that extra power to go faster, and I think the brakes / chassis on a Savage aren't up to going a whole lot faster
RycaShawn of course has a brake uprade, and the bike can be made to handle better, just not a whole lot better, unless you're going to spend a lot of money, and if you're going to drop a ton of cash, you could afford to just get a faster bike that designed for higher speeds
Like i said before, you can do anything at all with the right skills and enough money, and I guess if it's worth it to you, there's no reason you shouldn't
It's still simpler to just get a faster bike, and probably cheaper, too, depending how fast you want to go

You can achieve a nice 50% bump in power with a performance cam, jet kit and exhaust, plus intake and exhaust head porting with the big bore kits. Still not a monster, but 45 hp on a bike that is sub-400 pound range is pretty nice, especially with peak torque at 3000 RPM. That being said, the frame on this bike isn't the strongest and is riddled with welds, some not of the best quality. I'd be extremely hesitant to put a hunk of metal much heavier than the stock engine (which isn't cream-filled by any means) into a non-stressed frame.
