No problem.
As for the clutch, change the clutch jet for a .40 and change the slave cylinder for an Oberon or similar, this makes the clutch lighter and easier to get neutral. As for down shifts, the engine has a sort of slipper clutch called a back torque limiter. It works off a vacume made by the throttle bodies and has a diaphragm behind the clutch cover. They have a one way valve half way down the hose from the throttle bodies, remove this and check it is working properly (blow through it and make sure it only goes one way). The best option is to fit an aftermarket slipper clutch.
