R1 engine swap

[AyJay]

Not the same because the character of the Gen 2 engine is that of the 2006 R1 (might be a bit earlier), not the brilliant carb'ed original.  The 98/99 R1 has more grunt everywhere than the Gen 1 Fazer despite Yamaha saying the latter was 'retuned for more torque'. 

I realise that, Mike. Toothy grin. I was just mixing it up a bit for the fun of it! I rode both the 2004 R1 and Gen 2 Fazer (matching architectures, in the same way the 99 R1 and 2001 Fazer architectures match) when they came out and the power deliveries of both are very different in character to the preceding models. I'm trying to think of a metaphor to describe it, but all I can come up with is the later models feel like a 600 with 40% more top end but only 10% more torque. Wildly inaccurate in the face of the actual power and torque figures, I know, but they don't feel like litre bikes, somehow.

They don't have the same gravitas and solidity as the older engines, the delivery feels thin and reedy rather than solid and robust. Something went missing when they started chasing revs to increase the power, probably the midrange. Midrange doesn't matter if you can pile on the revs really fast, you just gear the bike down a bit, which is also a 600 trait.

Have you ridden an MT-07 yet? That engine feels just like a Gen 1 Fazer's younger brother. Lovely power delivery.

A 4XV R1 motor in a Gen 2 frame ... now that's an idea!

Mission impossible. Can't be done.
Arf!
