Upgrading your Cat Kitty engine can significantly boost its performance, making it more fun and responsive. This guide provides essential modifications focusing on governor bypass, carburetor adjustments, gearing, and clutch maintenance to maximize your Cat Kitty’s potential. Whether you’re aiming for backyard fun or competitive racing, understanding these upgrades is key to unlocking extra power from your cat kitty.
Bypassing the Governor for Increased RPM in your Cat Kitty
The governor in your Cat Kitty engine is designed to limit the engine’s RPM, restricting its top speed. Bypassing this governor allows the engine to rev much higher, leading to a noticeable increase in power. However, this modification can cause fuel starvation. When the engine revs excessively, it can quickly deplete the fuel in the carburetor bowl, typically within about 15 seconds. This fuel starvation results in rough engine performance as your cat kitty struggles to maintain power.
Upgrading the Carburetor for Optimal Fuel Flow in your Cat Kitty
To counteract fuel starvation after governor bypass, upgrading your carburetor is crucial. Installing a 2.0 needle & seat is highly recommended. This specialized component increases the fuel flow into the carburetor, ensuring a consistent fuel supply even at higher RPMs. While 2.0 needles & seats are available from various parts suppliers, it’s essential to ensure you obtain the correct one for your Cat Kitty model. Furthermore, adjusting your jetting from the stock 72.5 (or 77.5 on 1977 models) to a 70 main jet is advisable. Cat Kitty engines often run rich with the original jetting, and this adjustment optimizes the fuel-air mixture for better performance.
Gearing Considerations for your Cat Kitty Across Terrains
Gearing plays a significant role in how your Cat Kitty performs in different conditions. For heavier riders or those operating in hilly areas, it’s best to avoid going below a 37 or 36 tooth driven sprocket. These larger sprockets provide more torque, necessary for climbing hills and carrying heavier loads. On flatter terrain, a 34 tooth sprocket is a safe option, and many riders opt for even smaller sprockets like 32 or even 30 tooth for increased top speed. However, going too low can lead to a noticeable loss of low-end power for your cat kitty. Current sprocket options often require a quick change hub, although re-hobbed OEM sprockets in 37 and 34 tooth sizes may be available to reduce investment, especially for non-racing applications.
Clutch Maintenance for Peak Cat Kitty Performance
Maintaining your Cat Kitty’s clutch is vital for ensuring efficient power transfer. A clean and well-maintained clutch maximizes performance, especially during acceleration. While the clutch spring is durable, it can lose tension over time, even within a short period. A weakened spring lowers the clutch engagement point, which can be the difference between a fast start and lagging behind, particularly in racing scenarios. For recreational backyard use, replacing the clutch spring every couple of years is recommended. For racing, more frequent changes, at least twice per race season, are advisable to maintain peak performance and competitive edge for your cat kitty.
