Terms Conditions & Warranties

We strongly recommend that all motor parts be installed by a qualified mechanic with experience working on these types of motors.  We send out installation, tuning and break in instructions with our motor kits.  Failure to follow those instructions may result in motor failure that will not be covered by warranty.  Warranty does not cover any failure that is a result of improper installation, improper tuning, improper break in, or misuse.  For any warranty to be considered the part(s) in question must be sent to us for inspection.
