Difficulties and ObstaclesDifficulties and Obstacles
• Problem: Many dimensions were immeasurable because of their location, i.e. valve guides, Solution: Dimensions had to be inferred based on function and location.
• Problem: Imperfections in machining meant that not all corresponding dimensions were equal. Solution: Dimensions had to be adjusted during assembly to facility function.
• Problem: Establishing a cam follower connection between the cams and the buckets. Solution: Rounding the surface of the bucket left for an easier 24 connections.
• Limitations of DSV lab computers made extensive cam/follower connections very difficult.

Difficulties and Obstacles (Cont’d)Difficulties and Obstacles (Cont’d)
• Not having the valve shims, it is very difficult in achieving the proper valve timing for the 4 stroke cycle.

Improvements and ModificationsImprovements and Modifications
- This engine will be used for drag racing, therefore instead of straddling the engine, the rider lays on top, eliminating the need for angled intakes. This also increases air flow into the cylinder head.
- Drag racing runs an engine hot for only a few seconds. Maximizing surface area to dissipate heat on the engine is no longer needed, though we still added minimal fins to act as heat sinks.
