after spending countless hrs making sure everything matched, had a better flow path, removing imperfections etc i found to my horror a bastard crack from kips port to exhaust port
yet another setback, does any one have any quick barrels with good plating for sale, i know im pissing in a force ten but worth a try cheers matt

Matt - they still run. Just rub over it with a bit of emery paper and it might be ok. My good set were cracked and I think I ran them like that for at least a couple of races and two dyno sessions with no probs.
Early TZ V-Twin barrels do the same.

mark, always good to hear some sort of reassurance, thanks! tbh i dont see any step and have been plated recently hence why they appear smooth. prob been that way years, just annoying when things look nice and new to see a hairline crack spoil the image! anyway on that news i'll proceed with fitting pistons etc and get the thing ready! also have some barrels as per t/sparrow (04 i think) with some marks on the rear facing bore ( near boost/r.transfer) will these be usable with new pistons+rings? gonna get replated soon any way. cheers matt

Probably - bring them to Cadwell and I will have a look.
What pistons and head are you planning on using?

looks like i''ll be using 4dp now (if peg located correctly) as i have a good source off mate! the barrels in question need squaring/tidying up as i need to get correct tool, fancy earning a few beer tokens?lol
will see you at cadwell anyway, cheers matt
