.One of the easiest and most reliable ways to improve the performance of a 4-stroke engine is to replace / upgrade the camshaft. According to Hot Cams, depending on the machine, a performance increase of about 5 - 10 % can be achieved.
The camshaft specialists offer two tuning levels for most motorcycle models. Modifications to the camshaft result in larger or longer valve openings. The Stage 1 versions offer more torque especially at low end speeds. The Stage 2 camshafts are developed for power gains in the mid to high rpm range.
This type of racing camshaft requires a relatively high level of mechanical know-how, as it is recommended to also optimize the carburetion / injection to achieve optimal results and to maintain the reliability of the engine!
Technical Specifications:
- CNC-machined from case-hardened 8620 forged steel
- Designed utilizing state-of-the-art software
- Developed and dyno tested in the USA
- Replaces original camshafts (drop-in) using stock valve springs (unless otherwise specified)
- 5 to 10% power increase
Attention! Some models require a slight modification of the cylinder head. Please read instructions carefully!
Camshaft and valve timing
The camshaft and valve timing are important components of 4-stroke engines. The camshafts allow the valves to open (i.e., to draw in the mixture and expel the gases) and are driven by the timing chain, which is in turn connected to the crankshaft.
Incorrect timing adjustment interferes with valve opening and can severely affect engine performance and reliability. Therefore, we recommend to intervene only with appropriate technical know-how.
Maintenance and tuning
Maintenance and care of the elements located in the cylinder head, including valve timing, is very important. Even though the timing chain generally has a fairly long life, it is still necessary to regularly check chain wear and wear of all related elements.
Camshafts must always be in perfect condition. You can also use tuning camshafts; the shape of the cams is revised to increase the valve opening times and thus provide more power.
