JIMS ® CHROMING Here at JIMS ® , we insisted we would never chrome our products, for the simple reason it is too hard to guaran- tee the precision tolerances that JIMS ® is known for. However, now we’re chrome plating with the best chroming and masking processes available. JIMS ® guarantees that there is no chrome in the crucial motor areas. Take a look for yourself.

EVO BILLET, POLISHED, & CHROME 7075-T651 TAPPET BLOCK KIT WITH THE BIG AXLE “POWERGLIDE ™ ” TAPPETS This kit replaces and supercedes black wrinkle tappet block numbers 18622-85A, 18623-85A, and Plain tappet blocks No.’s 18540-86A and 18542-83A. Designed to accommodate a gross valve lift of .655” at the valves, leaving a clearance of .035” roller to block free play (Please note: If using a cam with a higher lift, a simple modification is all that is needed). These blocks will clear most small base circle cams having a lift of .655” or more. JIMS ® EVO Tappet Block Kit was produced to improve the stock tappet and tappet block area. Made from billet 7075-T651 aluminum with a tensile strength 3 times stronger than cast aluminum tappet blocks. These tappet blocks are machined to the center line of the cam and hold ± .002”. Also, the bores are held perpendicular to the mounting flange to ± .0002”. Add the precision quality of JIMS ® Tappet and you can’t buy a better tappet block kit for your bike (Gaskets and chrome screws included). For the ultimate in valve train technology and stability, add JIMS ® Roller Rocker Arms (20 grams lighter than stock) and JIMS ® Billet Cam Cover. Use with any EVO Big Twin adjustable pushrods.
