Klaviatura 1000cc vysoký zdvih

The smaller bore motors of A-series range of engines have a cylinder head with valves that are spaced much closer together than the 1275cc. Thus if you have a 948cc or a 1098cc cylinder head then you probabaly can make use of these special 1.5 ratio roller rockers that are setup for the small bore heads. This is a full roller set and thus has roller bearings both on the rocker shaft and on the tips of the rockers that contact the head of the valve. The full roller set has less drag (more horsepower) and better response time then those with bushes on the rocker shaft.Spare parts are available -adjuster screw C-AHT442, nut C-AHT443 and the shaft C-AHT445.
