Uma Racing R4 6.7 Lift


New Member
Hello guys and admin, this is my first time posting on this site, i'm just wondering if anyone can answer my simple question. I have a loaded and modified engine Yamaha Sniper 150(T150)
Engine Specs:
BRT Head 19/22
Uma Racing Valve Spring
Uma Racing R4 Camshaft
JVT 57mm Chrome Bore

This is my first time using this kind of camshaft which is the Uma Racing R4 ever since i used this cams it went from silent to ticking noises. Is it normal to have that ticking sound on the part of the head cylinder because it is a high lift cam ?
