Note there are 2 variants of the PHM slide – early and current, the current slides will have to be modified to fit the early carburettors.

*** Please make a note on your order if you need the slide to be modified at no extra charge to fit the early type caburettor.

The important difference is the width of the stop screw ramp – please see picture:-

p/n 8639 Ramp slide 4.45mm wide

p/n 11815 Ramp slide 6.2mm wide

Please measure your existing slides before purchasing a replacement.
