The Cyclery Paul Weyres Racing Cams IOE 1917-1929
The Cyclery Paul Weyres Racing Cams IOE 1917-1929
Your old IOE machine will benefit from a performance cam, too, especially when combined with a later style 1-1/4” or 1-1/2” Linkert carburetor. Higher lift lobes and longer duration will improve breathing and easily free some extra ponies. The W&W Wrecking Crew tested this cam shaft in a 1929 JDL and the results were highly satisfying, with overall performance nicely improved on both public roads and occasional race track missions. Excellent European made quality.

The set comprises 4 cams, generator idler gear and the pinion gear.

The Cyclery Intake Housing Ring Nuts
The Cyclery Intake Housing Ring Nuts
Quite a cool thing that The Cyclery has invented and presenting here. Instead of simply offering replacement ring nuts for the intake housings of IOE models, they have addressed the problem of loose intake housing nuts. Until now, the solution to this was to weld and/or rework the threads in the cylinders of the pocket-valve V2 engines.
The ravages of time, unilateral pressure from the inlet tappets and pushrods, heat that weakens the structure, a lack of care when retightening the ring nuts - all these factors contribute to the fact that after about 100 years, the threads in the cylinders into which these nuts are screwed have widened and are no longer cylindrical, but often also conical. So it makes complete sense to offer oversize nuts as an uncomplicated solution for such maltreated threads. This way, reworking, welding and similar costly repairs can be avoided.
The nuts are manufactured in different outer diameters and you order two or three sizes to check which one fits your cylinder best. Of course, we will take back the nuts you don't need, as long as you have treated them well and screwed them in with a suitable tool and not with a pipe wrench.
