[Crosswind]

Any explanations on the following?

For performance,

1. What's better? Flat top piston or dished piston?

2. What's better? higher the final drive or lower the final drive?

I can answer your first question. if you use flat top pistons your engine will perform very aggresive.it vill be very fast. very quick responce. accselaration will be very high and also you can hear your engine beat without a beat silancer.

AND ALSO

because of flat top pistans the presure inside the engine will be high. you have to use a good packing set for your engine (british packing set) and the oil presure of your engine is high. do not put oil higher than the MIN mark of the oil tester. and you have to use a fiber washer in the engine oil nut at the sump.

if you follow these it will work fine. this is all through experince. in my mini I HAVE A MODIFIED FLAT TOP ENGINE. IT CAN GO UP TO 80 KMPH IN JUST 10-15 SECONDS. OH!... YEAH IT FEELS GOOD

have a nice day.
