One advise.
Use Ravi Piaggio own valves.
Do not let them alter other bikes valves and install it in yours they will leak and won't last past 4-5k kms.
As they shave away all the hardened and treated surface from it.
I had a post in one of Ravi thread about it. Search it for more details
Do share prices for items.
I bought rpm cable for 250rs in pindi.
