Magnum .15 XLS

[John Rist]

Has anyone had any experience with the RSM Magnum .15 XLS.  AS I understand it RSM has converted it to a CL setup.

Hi John;

I prefer that engine over the LA.15 because it has twin ball bearings, and is a true ABC. Pop a custom designed venturi in the crank case, run a ST needle valve through the hole and you are good to go. Never had a problem with any of the ones I have sold over the years.

Regrettably the XLS ABC piston/Liner fit is variable. It ranges from acceptable to terrible. The OS .15 LA fits are much more reliable.
