SK, men kisi ko bhi apni bike berbad kerny ka mashwara nahi dena chahta becuase if you ride is running fine then why bother, but if you ask me what engine I would use for my RP then thats what I can tell you, I am going to swap it with a CG200 lifan engine.
you will think why ?
1 - Its spare parts is all avaialbe in local market
2 - Its long lasting as its lifan and we already see it getting quite abused on rickshaws so its like a certificate of power that it really pulls.
3 - Its 16BHP with 15nm of torque which is going to make RP dance with power, what top speed it will get thats can only be found out after its installed
4 - Its water cooled and there would be not heating issue whether you take it to karachi ..
and thats what me and angel82 are going to do today InshAllah! @saad.bukhari1 angel82 told me u r also interested if so you must call him before 1pm because we would be placing order by 1PM. becuase aik dafa order place ho gya then dubara possible nahi ho ga becuase it cost would be over all calculated including shipping and many other things.
Price ka abhi humien khud nahi pta market men its 38k but the angel82 importer links we are using we might get it some where in 25k +/- .. InshAllah.
