I just recently purchased some new air cleaners from Motorcycle Accessory Warehouse.
http://www.mawonline.com K&N part numbers RU1370 and RU1371 $33 and $38 (you need one of each). They also have Russell Cycleflex front brake line kits for $86 but you had better hurry as they are listed as closeout.

has Andrews cams and C gears, PBI front sprockets and they used to have Arias forged pistons in 9.5:1 and 10:1 compression ratios. These are available in three sizes: .010", .020", and .040" over. I only know that they still have the 10:1 .040" size since I purchased a pair earlier this year. The price I paid was $275, not too bad for pistons, pins, and rings.
