Installing 92mm feracchi high comp pistons

[2or4strokes]

Hi

 

Have any of you install the feracchi high compression of 92mm bore which he claims is a slot in pistons. Is it any good ? How much more power can you gain and most importantly is it relaible.

Its all about the mid range- ignore the Ferracci hype about extra peak power, but you will get a big shove of grunt just where you want it.

 

I know a few members of this forum have fitted them with no issues at all. I have sold my V11 but it never had any problems with the new pistons in the 15000 miles or so since they were fitted.

 

Take a look at this thread:

Absolutely!! You will find the throttle response and roll on acceleration are so much better - and the exhaust note is a little sharper too! Great improvement!!
