Hey guy's , I noticed two annomilies unfamiliar to me, in reguards to a recent 93' model ,MC21' SP' aquisition? The first is , that the OEM 'SP' fork-tubes have a ''relief'' cut ,with a ''circlip'' installed ,approximately 2.5 inches below the top of each tube?? never seen this before on other MC21 'SE' or 'R' fork tubes? or its purpose? Also , the dry-clutch 'SP' motor, has the HRC ''racing'' logo on the OEM clutch cover , as well as "honda racing'' cast into the aluminum side-engine-case? never seen that on any of my other MC21's either? any info. appreciated.;dave
