Asalamoaleykum
No doubt the work done by nadeem bhai has become a reference if anyone wants to do it in a genuine way....
I have gone through same and facing problem with cylinder and sleeve issue...
I want to take opinion in the light of all comments from xulfiqar and msabbasi..
Mostly the sleeves istalled are of cast iron...
I think the original sleeve is of stainless steel... So i want to put a stainless steel sleeve in my GTO cylinder with proper and accurate intake and exhaust holes.. Im sure its gonna work awsome.
Please comment on making steel sleeves and any place in Lahore who is expert in this type of fabrication.
