250r triple tree question

[Aka_am]

Can stock 85/86 triples be bored out 4mm? i have some 43mm forks i want to use, and i don't have the triples yet. But can they safelly be bored out 4mm? or will i have to sell these and buy stockers, which i'd rather have these.

stock is 39mm btw.

I'll post some pics of them, later tonight.

Allright After much searching and searching and searching, and i'm tried. I've found out, cr500 forks are 44mm and that's a popular swap.

I've looked at the pics and there looks to be plenty of metal, Can anyone post if they have had problems with that setup?

When i wake up in the morning I'm going to fit the forks onto a 250r rim and axle i have and make sure that fits and try and figure out how I'm going to get a caliper onto these.
