yea, from top, side back front, etc...it's a pita...
i just started wrenching on cars again after a long while...mang...so much room! even $#it people call a pita cause of no room has like 50% more room than some of the bike stuff!

 

i would use a 1/4 ratchet with a few different extensions and a u-joint. the u-joint is a must! its not too hard if you know your ways with tools. make sure to put some anti-sieze on the plug threads!

 

go from the top just prop the take, take the air box off and bam your there.. also use the honda spark plug extenstion/socket so much easyer.. if you are doing it on a 600rr.. then only way is to drop radiator and get them because of angle of engine
