Hi, am about (well thinking about) to get a set of Keihn FCR's but I was wondering what bore size.
I'm looking at FCR D33mm.
Has anyone got any experience with these or experience with FCR's in general.
These are the proper FCR's and not SP's.
I will contact my engine builder for his advice as soon as I can find his number, phone wiped out this morning :smt013
These are for a race bike.

Thanks
Jonesy

You have a PM

So what is the difference between SP's and Proper FCR's cause I thought the FCR's on my SP were proper items.
