couple of questions

[marcboy62]

hi ive recently think about buying big bore cylinders and sell my pistons wiseco 795, my stroker crank and my ported cylinders who are too much ported for me . I will buy the 392cc athena big bore cylinders kit with pistons but i also want a stroker crank to make it 421cc i want to sell my old stroker because its also long rod and i would need to change the new pistons..

so let me know what you think about this. i have a couple of questions to ask too.

2.does stock ported cylinders are much powerfull than non ported big bore cylinders?

3.what is the difference between PWK and air strikers Keihin carbs?

4.what is a serval cub?

5.should i keep my coolhead with this kit or the head that comes with will be similar?
