Tools? Groove dimensions? Location? PDF Print E-mail
What kind of tools do you use to make the grooves?
 How do you know how deep to make them?
 How long to make them?
 And Where to put the grooves on both two strokes and four strokes?


ANSWER:
The first grooves were started with a jewelers saw and finished out with a small triangular file.

The depth is dependent upon creation of a straight shot from the plug to the squish area.

Length is also.

Usually in symmetrical orientation. Every engine is different and research will need to be done on all scales. Grooves may be added and benefits received until a certain point. Next time do one less. :)
