- Both the R3 and R4 motors are easily lubricated with a little disassembly. Metal bearings should be lubed every six race weekends or so. Ceramic bearings should be lubricated twice as often. Again when you lubricate, use the minimum amount of lube!
- The R5 series is easier as the timing side bearing has an inspection hole in the standard edition on the timing end cover. If you have the 'Dirt Cover' option, then use the R3 & R4 steps for timing end bearing lube.
