BSA Valve Guide Set 68-0809 Bronze STD Standard 1962-70 Lightning Royal Star
USA Made BSA 500 & 650 Unit Twins Standard Bronze Valve Guide Set. This is as good as it gets! Machined right here in the USA using the best quality materials available! There are other guides being sold here on the internet but not of this quality! We recommend using these guides as the material (Phosphor Bronze) is compatible with alloy cylinder heads and provides a tighter & more accurate tolerance then your standard guide! Valve Guides are "Standard" and have a Diameter of .501". Fits all BSA A50 & A65 Twins (Lightning, Thunderbolt, Star, Rocket, Royal Star, Firebird, Hornet, Wasp, Cyclone & Spitfire) from 1962-1970. Please refer to your parts catalog for proper fitment.
*****Please note that this set (recommended) will replace the early cast-iron valve guides! Set is not compatible with OIF models from 1971-1972!******
