if Mike did it, there was a good reason
I've wondered about boring out some PHF 30s to 36. Seems like the castings are all the same (30, 32, 34 & 36) it's only the bore that's different. True? Perhaps the VHBs couldn't be bored any larger than 31?
30's and36 PHF's have the same body, I have a pair of 30's to bore out but I need a bike to use them on.
That's most likely the case, as the vhb's only go up to 30mm. Unfortunately I don't know if this bike is ever used for racing..The PHF's seem to use the same body. However, I found a post about boring out the phf 32's on the laverda forums, and it doesn't seem as easy as you might think..http://www.laverdaforum.com/forum/index.php?topic=89062.0
