What engine would you choose?

Aussiejoe · Post by **Aussiejoe** » 12 years ago

If you could graft any engine into your Raptor, what would it be? I think picking a Ducati would be self defeating, and it has to be something that has a chance of fitting, so no 2.4 litre Trumpy engines or Kwaka Z1300s.

For me, either a 883 Harley Skirtster or an Aprilla RXV550.

I would change me 650 engine with a 485 cc rd based motor from downunder...

110 hp and a torque that can get your hands 20cm longer...

Aprilia RSV4?

the TL lump is a peach standard and has plenty potential if you want more.

It also suits the bike and looks good.

I had a Buell XB12R which is a similar bike with a tuned sportster engine but its still a bit of a tractor.........................

If anything I`d go lazy and fit the Triumph Thunderbird twin engine. (doubt it would fit without getting out the gas axe)

Likewise, I think the TL lump is as good as it gets. The only engine that can out monster it, is a Hyabusa engine, and if I'd wanted one of them, I would have bought a Hyabusa.

Always fancied a V4 but there's none of the current crop that I particularly want to own. So it would be a VFR 800 then. Like the TL, another example of a fine engine in a crappy psuedo race style bike.

well with everything you have all done to the good ol rap the engine must be the last thing to try and change?

I'd take the VFR750 engine, over the VFR800.

How about a Brittan lump?

Yes, sorry Britten.

I'm seriously considering doing this in the future, I'm a metal fabricator so actually fitting it wouldn't be that hard, and I'd make the engine mounts so you could adjust the position of the engine.

No parallel twin or V4 would fit inside the frame rails(unless it as a very small capacity), and there is no way I would modify the frame at all, that can just lead down a road to major problems. The engine also has to fit in high enough so you don't lose ground clearance. The engine also has to be a stressed member that imparts some rigidity into the frame. I just want to build something different to what everyone else has.

A Britten, now that is more like it, know anyone that might have a spare one lying around Araf?

A single would also fit in, maybe a 2 stroke single dirt bike engine like a CR500 or an IT495.

Being a woman I don't really understand the question

Don't you just buy another bike

How about a ktm 990 lump? Having said that, an rsv mille V2 would work, but why not just tune the devil you know rather than faffing around with new ecu, exhausts and wiring etc? I believe the tl lump is pretty bombproof.....

It's the challenge of doing it, and I'm a guy, we have to stuff with things

I just want my raptor to be different, just like I'm looking at getting a rear wheel hugger for it made up like the one on a Bimota Mantra.
Was going to customize a pop up head light Suzuki Katana and make a a triple pop up headlight fairing out of alloy and graft in a bored GSX1100EFE engine. The only reason I didn't was because I had to use it for my courier bike, and someone decided to do a u-turn in front of me while I was doing 60 km/h. The frame got bent in the crash. I'm also looking at the possibility of racing it and exploiting some rules or being able to race it in a different class. I will also look at getting a different tank, probably make one out of alloy, so the original doesn't get wrecked. I just love that chassis, and even if I throw everything else away and replace the lot with parts off other bikes, it will be fun to do. I'm already in the process of doing that cause Cagiva stock no spare parts in Australia, it's a 6 to 8 week wait , but if I can put aftermarket or parts from another Jap make on it, it will be easier to source parts in the future.

Thanks to everyone for the creative responses, the question obviously got people thinking!
