i have an aftermarket triple tree on my supermoto i want to fit front forks but the are 48 and the current forks are 47, can i bore my triple to fit the 48?
I’m sure that there’s enough material to allow a 0.040” increase in bore diameter. Any halfway competent machine shop could handle the job.
I think they'd have to be more than halfway competent... Aligning/maintaining center-to-center and offset on top of concentricity with open/gapped perimeter holes? Prolly cheaper to buy one.
It's easy to maintain concentricity. You just shim the gaps and tighten down the pinch bolts. The rest is basic alignment that needs to be done. If the shop doesn't realize that, then they aren't even a quarter-way competent
Just need to indicate each bore for concentricity. That’s what dial indicators are used for. Easy enough setup, too
it's only a PI more in circumference. squeeze em in there don't do it. can't you sell your stock triples and get properly sized ones?
Hell you could get a 40-50mm cylinder hone and hone the triples. And chuck up the fork in a lathe and take a little off with some emory paper. Easy peezy.
