Fork swap. Any surprises?

I snagged an '85 VF1000 when I got my '84 VF700F. Like the headline says, I'm planning on swapping the bigger forks and a few other parts.
They look identical, but for the diameter, and the rotors and calipers seem to be the same as well. Does anyone know of any snags I might run in to on the rebuild or whilst riding?
Thank you in advance,
Gator

 

I've no experience in this specific swap but the most critical thing is likely to be the steering stem length (If not the same) as you'll need to swap the triple clamps and handlebars across to match the fork diameter. You can always swap the brake master and calipers as a set too. I did a hybrid swap of a VFR VTEC front end onto a VFR800Fi and the only area where there was any issue was the steering lock as the ignition barrel ended up at a slightly different height and the locking pin wouldn't engage the socket in the frame.(fixed with some shimming with washers)

 

That should all bolt right on. Distance between discs mounted on the wheel is the same between the two, front wheels are identical.

Triples are identical I think except for 41mm vs 39mm.

Swap over the TRAC stuff from the 1000. Calipers are your choice, they are really the same expect for "HONDA" vs the crosshairs casting like the old HRC race bikes.

1991 - 93 VFR handlebars are a slightly sportier choice. Just a little material removal near the fuse cover to get them at the right angle. Have them on my VF1000F.

 

Thank you gents. I had planned on swapping the triples, wheel and calipers just to be sure. My biggest concern is wether there is enough of a weight difference to matter or some weird tuning issue to deal with.

Any firmer springs from the heavier bike will be welcome. Honda springs are always woefully weak in the 80s and 90s.

And goodbye 39mm.

Oh... you said "85". Is it a VF1000R or VF1000F?
