hi all,
just joined the forum today so hi to you all, i have afew questions for you all, as my ive just had to take my mc15 r5k apart again, i had my barrells plated by langcorts about 500 miles ago and just had a minor nip up, ive taken the barrells off to inspect them and both have marks on the pistons and rings where they have been passing over the exhaust port bridge, im guessing they were never releived after they were plated, my question is can i releive them myself with, say 400 grit paper, if so how deep should i go ? 0.05 mm perhaps ??? and lastly will i wear through the nikosil doing this and does it matter
thanks for any light you guys can shed on this for me
steve
