84-99 Evo Big Twin with carburetor (NU)
Part Description
S&S, 84-99 flywheel assembly for OEM 80" engines
4 -1/4" stroke. Stock replacement for 80" (1340cc) carbureted Evolution Big Twin models. Used with stock or stock weight pistons like S&S 536052 series. Re-balancing is not required. Note: These flywheels are not notched and therefore not compatible with fuel injected models. Note: For 90-99 models, with stock 3-piece flywheels with non-removable sprocket & pinion shafts, it is required to use pre-90 pinion shaft parts when converting to any (early) 5-piece flywheels assembly. S&S offers these parts as 904148, a '90-99 Pinion Shaft Conversion Kit'. Note: In any and all applications the technician must be able to judge components for their suitability in combination with the other engine components, prior to installation. It is of importance that a knowledgeable mechanic will install & make adjustments as required.
