Someone talk to me about L&T clutch for a mac 101 on a sidewinder. Good or bad? one disk, two or three? You guys have more experience with disc clutches than I do and the Horstman is getting to hard to find and get parts for.

The L&T is a great clutch for a 101. The three disc is the most durable but a two is a little faster. For a 101 you will want to find a 10 tooth #35 chain drum and you will want to change out the springs to a lighter (smaller wire diameter) version. With the standard springs typical of the clutches used on KT100s you won't be able to set the engagement any lower than about 9,500 and that is too high for the 101. With the softer springs the range of adjustment will move down the rpm band so you can set the clutch to engage in the low 8K range.
A realistic evaluation of the skill of the driver is the best way to decide on what version to buy. Basically, the faster the driver, the easier it is on the clutch. If the driver is slow through the corners then the clutch will have to work harder (longer) pulling off each corner and the heat builds up. With more discs there is more material to spread out the heat so the three disc is better unless the driver is quick ( and light). The three disc is the most common so you should not have much trouble finding one.

Steve you said in your post "the lighter springs". are you talking about a set from a different clutch? I ask because looking at the L&T website they don't show a lighter spring just springs from different clutches.
