Forks - Amount of travel

Is it bad to change the length of travel - at the mo I have 100mm. Have seen 2007 recon 327 for £170 in good condition, right steerer length etc but its 120mm travel. what effect will this have on the bike (Hardrock 2007)
thanks

Increasing travel can invalidate frame warranty, so if this I'd contact Specialized before you fit them.
Also, an increase in travel doesn't necessarily mean changing the goemoetry. Axle to crown length of the fork is the more pertinent dimension. Probably is longer, but it's worth checking.
