What are you guys thoughts on iridium and platinum plugs ?

 

Most of the non-Harley Shops sell Amsoil in the Fort Worth area. I get mine at Bikers Bay which probably has a store in your area.

 

Don't forget to change your tranny oil to Redline heavy shockproof, and your primary to HD Formula +

 

There are several threads on here about plugs as I just went through them looking for recommendations for my 103. The concensus seems to be stick with stock plugs unless your having problems with fouling or other issuses and yes the 103's still call for the 6R12. I've been using all Mobil 1 products without problem 20W50 in crankcase, 75w90 gear lube in trans and 20w50 in primary but may try some clutch approved non-sythetic in the primary next change as I hear its better for the clutch. Most of the bike shops around here carry the Amsoil products as optional but online is cheaper. Cycle Gear also carries the Redline and GearSaver products. Do not have enough miles yet to do plug wires.

Not sure about the 2001's but do not forget o-rings or seals for the drain plugs and any gaskets needed for clutch and chain tensioner adjustment. My o-ring seals seem to be pinched or cut every oil change so I just go ahead and plan to change them.
