Výfukový ventil, velký zámek 850 998 1100

Early Large cotter groove exhaust valve.Most small-bore engines seem particularly prone to burning valves, it is highly recommended to replace the exhaust valves when you do a valve job! This 1.0″ valve fits most early 948cc, 998cc and 1098cc engines. These are better than the originals but for 998 Cooper 12G295 heads we stock the best quality AEA400 as well. These have the wide rectangular groove to accept the original 2A11 cotters which are no longer available.
