I own a '84 Yamaha FJ600 that I use mainly for fast rides on
back roads. I have been experimenting with the front suspension,
specifically air-caps. The '85 FJ600 comes with air-caps, the
'84 doesn't. 

Recently an amateur racer, who also rides an '84 FJ600, 
suggested I forget the air-caps and install progressive springs 
in the forks and bump up the fork oil from 10w to 15w. He claims 
that tuning with air-caps is impossible since the air expands and 
contracts due to temperature. Also, air tends to leak somewhat. 

My question is: Is he correct?  Why then do most sport bikes 
now come with air-caps? For hard, fast riding, which is more 
likely to improve handling, the air-caps or progrssive springs?
Would some combination of the two be even better?

Thanks,
Jay
