Hey guys
I have a set of pro circuit triple clamps for my 2007 Cr 250
So obviously they are for the 47 mm forks
I have a set of 48 mm forks I want to use on the bike
Has anyone machined the bores to fit the bigger forks
Any problems anyone knows of before I go ahead and do it
Cheers

As long as there will be enough material left you should be fine.

Measure the clamping surface of both forks to know where you stand. The size of the lower tubes has nothing to do with the clamp size. You may need to bore one or both clamps, may need to sleeve one down or they may slide right in...

Both top and bottom clamp need to be bored mate
I have not yet measured them as my verniers are in my work but I will in the next couple of days

Gotch'a, just letting you know it could go the other way. I've seen plenty that were bored with no issued so I'm sure you'll be fine!
