KPMI® 2014 Product Overview



Kibblewhite HD® Evolution™ OEM Styl Seals & Tools Kit

Harley-Davidson® Twin Cam™ 88-103 Fat Stem Valve

  • Some later model Harley Twin Cam™ heads using 7.0mm valves may have a tendency to crack in the port end of the valve guide boss. This has been noticed on heads with the number 332 embossed on the cylinder heads.
  • KPMI® is now producing Black Diamond™ Valves with +.005” oversize stems for engine builders who need to reestablish correct valve stem to guide clearance, but do want to take a chance on creating a crack, or worsening an existing crack by changing valve guides in these heads.
  • The valve guides must be reamed/honed to set the correct clearance, and then a valve job should be performed to insure proper valve sealing.
  • The oversize portion of the stem does not extend into the keeper groove area, so the OEM keepers may be used.

Harley-Davidson® Twin Cam™ 88-103 Wrist Pin Bushing

  • Designed and manufactured by KPMI® to original OEM dimensions with Kibblewhite® Quality and Precision. Wrist pin bushings need the correct combination of characteristics to perform properly in their high load environment. These bushings have excellent anti friction qualities, as well as good hardness, and resistance to wear and deformation under high loads. KPMI® wrist pin bushings are held to tight dimensional tolerances, offer excellent machinability, so the optimum surface finish may be obtained, and have a tapered lead on each end to ease installation. These wrist pins will meet or exceed fitment and wearability of all other replacement style bushings available.
