Equipment Modifications

• The side rails next to the engine will need to be cut in order for the starter and oil filter to clear the frame
• The engine mounting holes will need to be drilled
• The left side panel will need to be trimmed for oil filter clearance.  This trimming will remove the latch for the side panel.  A hole will need to be drilled through the side panel and the side rail at the front bottom corner to reattach the panel. The hardware for this is provided.
