(these are all approx estimates but are super super accurate and close to reality of expenditures whcn you import some thing related to Automobiles.)
a 4 valve 160 or a Daytuna 200cc (zongshen 190) which can fit bolt to bolt has a factory tag price of 480$ these days
Which translates into:
1 - Factory Price (complete kit): $480 X 170(TT) = 81,600/-
2 - Shipment of single unit to 5 units (in case of zongshen it is 45 sets) is almost the same as it is considered sample order = 22800 (average)
3 - Custom Duty (evaluation on 35% ~100%) = 40,800/-
4 - 17% GST on (fac price FOB shipment) = 18,900/- (approx.)
5 - special, W.H.T, various tax, other taxes = 10,000/- (budgetted)
6 - Clearance agent fee = 20,000/- (ideal minimum mostly its 40k and above including speed money if and where ever needed)
This makes it a total of 1,94,100/- (AIK LAKH CHORANWAY HAZAR AIK SO) Rupees make a plus minus of 5~k to 10k and thats about it... this estimate is this much accurate for a legal way to import a 200cc or a 160cc 4 valve engine, now let me know if u r interested, I will share all the paper work with you and the day to day progress as well so you know what you paid was spent for real..
I have brought these in the past though they used to cost 88~90k at max but not any more, as factory price is almost that now.
then thee is an illegal way of importing engine in which it is hidden b/w other things but that is a risky engine and I never did it, but hear that most chinese 'Heavy' bike show room owners are doing it.
