Cardinals camshaft 125-155 R125 - MT 125 - XSR 125 VVA
(0 review)

Cardinals offers you a Racing V63 camshaft for Yamaha Minarelli 125 4T LC Euro 5 VVA (variable valve timing advance 4T) engines.
This is recommended for use on prepared engines from 125cc to 155cc. The camshaft is one of the most important elements on a 4-stroke engine.

The Cardinals V63 camshaft will give you a performance boost in terms of throttle response and high rpm. Can be fitted to the original cylinder heads but also to the racing ones.

Technical advice :

To remove your camshaft it is necessary to remove the water pump from your bike. We advise you to buy a water pump housing gasket. Be careful, if you use a high compression piston you will have to check the gap between your valve and your piston when fully opened.

1- To install the "Cardinals Racing Cam" V63, the original (OEM) valve springs must be replaced with Racing valve springs that support at least a 9.5mm compression camshaft.
Failure to change the valve springs may result in damage to the cam lobe.
2- Must match cylinder kits with a recommended bore size of 52mm to 58mm and the cylinder head must have 19mm exhaust and 22mm intake valve sizes.
3- To get the best performance from the engine, it is recommended to use a degree disc to adjust the camshaft (with an adjustable timing wheel can further improve the fineness of adjustment).
4- The best recommended compression ratio is between 1:12.3 to 1:12.6.
5- Please make sure that the valve spring lift is accurate, otherwise an unusual engine noise may occur and the camshaft may be damaged.

An adjustment manual with diagram is included in the box with this product.
