Description
The standard non-chrome No. 3.5 slide for the PWK28 controls airflow and carries the jet needle. Its cutaway influences the mixture as the throttle opens, chiefly between 1/8 and 1/2 throttle.
Keihin part N502-11H00, order number 018-582. This is the standard non-chrome valve at PWK28 reference 13, not the optional chrome No. 3.5 valve N502-52H00.
Standard throttle-valve setting: PWK28, carburetor order 016-144, uses No. 3.5. This N502-11H00 non-chrome slide matches that original standard specification.
This is a single No. 3.5 slide, so there is no size dropdown to reorder. Within the same compatible slide family, smaller cutaways give a richer mixture and larger cutaways give a leaner mixture as the throttle opens. No. 0 is the richest end and No. 9.5 the leanest listed end where offered; those endpoints are not additional options for this product.
