Anyone know who makes the best manual clutch kit for the fiddy? I am planning on replacing the auto/centrifigal clutch on my sons xr soon with a functional, manual clutch. He will be ready to upgrade to a bigger bike before long, and I want him to learn to use a manual clutch on a bike he is already comfortable riding. How hard is the install? How reliable are they? Is the friction point adjustable? How about total cost? All things I must consider before doing the mod! Thanks in advance for the replies!
