KIBBLEWHITE Valve Guide - Manufacturer Ref: 30-30610
Bronze C674 valve guide designed for intake applications on off-road motorcycles (enduro/cross). This Kibblewhite insert offers machining characteristics suitable for modifications and repairs: a softer material than the premium C630 series, it can be bored and honed more easily with common tools (electric or cordless drill and ball hones).
Ideal for mechanics and DIY enthusiasts looking for an easy-to-adjust guide when refurbishing cross or enduro cylinder heads. Particularly suitable for Honda CRF 250 R/X models (years 2017-2018) listed for compatibility. Use appropriate honing tools to achieve optimal sealing finish and ensure the longevity of your valve train.
