New to me - 2000 Cagiva Gran Canyon

[koko64]

The Gran Canyon’s run the ‘W’ heads (750 cams & valves).

But a 900ie version of the W heads, so the 900ie heads with big valves and hot cams should be a straight swap if ever required.

How does the bike feel for torque? I thought about the low rpm grunt the motor must have with those heads.

Head swap = 

But, you would need to revisit the air/fuel mapping...  I think it runs a Magnetti / Marelli 1.6 ecu.  Not sure on the pin outs, but it could swap with a SS900ie ecu.  Or Monster.  Or nothing works and you’re hosed.

Check a GC forum as you won’t be the first should you go down that road.

Tunable Eprom chips iirc.

Thanks to both of you for all the info and  ideas about head swaps...

I've got limited seat time so far (and still need to put a license plate on it, which will take a day-off trip an hour into town), but I really enjoyed the feeling on the ST2 that you had freight train torque available from pretty much any reasonable RPM, and the Cagiva seems even more willing. Much of the non-city part of the 2 hr ride home was swinging along gentle curves in 6th gear at 95-100 kph, and the first time I went to pass a car I downshifted but after that I just left it in 6th & twisted on another effortless 25-30 kph.

The one issue I have noticed so far - and this may be as much a comment on my limited dirt experience as anything - it's tough for me to keep a steady throttle on rough gravel/forest roads. With me bouncing around a bit, a goodly bit of that torque is coming on and off with each bump.

Cool ride!

I'm weird - I put plenty of stickers on my old cars, but am really hesitant to put anything on a bike. But a residential sticker seemed like an appropriate accessory for this one, and it lets me bypass the entry gate:

You get a pass. That one fits the attitude of the bike.

I finally got around to the obligatory photo:

The regulator under the luggage rack?

Thinking about it, I would only swap heads if I fitted hi comp pistons in order to keep the low rpm tractor torque. The torque comparison chart shows that strong bottom end grunt. On the other hand, the hotter heads would soften low end power making dirt roads easier while increasing higher rpm power. The instant torque helps haul the bikes substantial weight around. Swings and roundabouts I guess.

The regulator under the luggage rack?

That's the one - probably SLIGHTLY better in that spot than tucked up under the fairing, completely out of the wind like it was on my 1998 ST2 before I relocated it beneath the bottom fork triple. It's a known achilles' heel on the GC's electrical system, well, one of a couple.

Or V2 heads w carby 900 cams?

I rode one in Varese one year we were traveling.  Loved it, but it is more like a mild MultiStrada and certainly not like the Elefant.

Cagiva made some great designs but they couldn't stay solvent (COCAINEISAHELLUVADRUG).

The Cagiva Navigator was the next step from the GC -- using a TL1000 engine.

So any news or updates on the bike? How's it running?
