I recently installed a LO206 in a child's snowmobile. I noticed it leaks oil when tipped on its side. Is this normal, or is something wrong?

The NHRA and IHRA have approved the 206 create what can be done to the motor to run in the 7.9 class without getting into the bottom end of the motor? Also are the valves the same size in all animal motors: ie world formula?

Asked by: Muncher
The 206 will not run a 7.90 without modifications. General feedback to date puts the engine a touch under 11 seconds in 'standard' trim. This is, of course, dependent on driver weight, exhaust, and so forth. The valves are the same as in the World Formula with the exception of the keeper height. The World Formula, due to its dual valve spring set-up and larger cam, has a higher slot in the valves for the keepers to allow travel without binding.
