● PROGRESSIVE DOUBLE VALVE SPRING & TITANIUM RETAINER SET (110CC & 125CC EURO-5 ENGINES) (14751-K1M-00T)
● The YUMINASHI Progressive Double Valve Springs in the set are intended to replace the stock single valve springs, and this to avoid floating valves when you run higher RPM's than the stock 9,500RPM ECU limiter.
● These 14751-K1M-00R double valve springs can be perfectly installed in the Euro-5 110cc and 125cc engines, and they make a powerful match with the YUMINASHI SS241 camshaft (LINK) (these Double Progressive Valve Springs can be used for racing/competition applications).
● If you have a cam which makes good power above 9,500RPM then you will absolute benefit from these 50% lighter titanium valve spring retainers because with reducing the reciprocating mass your valve springs have less weight to deal with, so you make it much easier for your valve springs and your engine in general to rev higher, and to get some slightly extra "free" horsepower in the higher RPM zone.
● The Yuminashi Titanium valve spring retainers are machined out of a high grade 6AL4V titanium, so they can run without any issue in combination with the double valve springs installed on your engine.
Titanium retainers are as light as aluminium valve spring retainers, but they are as hard as steel, so they won't break as aluminium retainers intend to do with double valve springs installed.
※ This set is also available in an edition without the Titanium Retainers in the package (Part Number 14752-K1M-00R).
※ A rule of thumb is to replace the valve springs each time you replace a piston...
● THIS PROGRESSIVE DOUBLE VALVE SPRING ET IS THE CORRECT SET TO BE INSTALLED IN THESE EURO-5 ENGINES:
