Check StockDesigned for carbureted F6/F7 models. Since the exhaust valves open at such a high rpm on the carbureted models the mid-range power is sacrificed dramatically compared to the EFI models. A recent dyno session at Dynotech has proven that our spacers drastically improve mid-range power by 10-14 horsepower. It adds a lot of mid-range power at an extremely low price. They also work well on 800cc big bore kits to allow exhaust valve clearance from the piston without machining. Machined out of aluminum, sold as a pair and comes with an easy install instruction sheet.
