Thread: WR, WLD, WL cylinders

    Re: WR, WLD, WL cylinders

    So the cylinders on my 38WLDR are the same as those on a WLD (assuming there correct 38's).

    I had the cases machined on my new race engine to take the roller bearings however if I do something with my other set of WR barrels I wont be going to that expense again.

    1940 WL (Race Bike)
    1944 WL

    Dave, if your cylinders are stock to your '38 WLDR they are NOT the same, early WLDR cylinders changed almost every year. '38 cylinders are unique to that year. or at least for late in the year They are small fin castings with larger intakes (1-7/16) and factory porting and relieving. WLDD and '40 up WLD cylinders are Big Fin and did not exist until late '39. Early WLD cylinders are the same as WL except for relieving and were used with high compression iron heads. WLDR cylinders were done in the race shop, WLD were stock production.

    What are the casting codes on your cylinders?

    Robbie,
    Guess it was just the angle of your first photo that made the WLD exhaust larger than the WL in the same photo.

    Ralph, they have really wide relief cuts around them and I think the shadows exaggerated them.

    Roller bearings are also known as cylindrical bearings and are not the same as ball bearings. 30 years ago when I had my WR engine rebuilt the engine builder converted it from ball bearings to roller bearings for extended life.

    Dave, those look like '40-'41 WLDR cylinders on your '38. Largest port size, straight valves.
