WHY ????
Seriously Really WHY???
Are you some desert racer Rally God??
If it is to say that you have one? In that instance, save your money and just buy a sticker
If you are going around the world? Just fit a new standard clutch with a new slave cylinder and an 850 final drive (to give you better low speed torque instead of lots of clutch slipping***)
Then all your worries are covered
*** Edit of course unless you have a GSA with the lower first gear
