hi everybody

i am still looking for help which is the best crank

how will the use of a packer plate at the cylinder base or head change engine characteristics.

Depends on your riding style, how revvy you want it? or is it more tourer?

If you want more torque less revs go 60 mm.

hi ...

i think that a longstroke crank (45020000) in combination with a PHBH 30 Carb. (40030000)

and an Exhaust SIP Performance New Generation (20019SS)

 

this Setup will give you a high tourqe and lots of Power without using a reed valve system
