Yup... It needs to be dropped at least 2 inches i reckon...
The story behind the 1641 is that this 1303 came with a 1300cc originally and during its time here was swapped with a 1200cc... Dont know why as there is no scarcity of 1300cc motors or parts at the kabaria's...
Since i bought it, it felt way too underpowered for my liking and luckily i came across this gentleman name Aamir Tirmizi who happened to be swapping out this 1641cc from his car with another 1600 having hydraulic tappets... i drove his bug while the engine was still in it and fell in love with the performance...
Its currently running 87mm pistons and crank is at .50mm... Carb is a 28PICT with larger jets and will be swapped with either a 30 or a 32 PICT one...
