T120 exhaust adaptor
One of the screw in exhaust adaptors just pulled out while I was tearing down the motor. The bike sat for almost 20 years, so there was quite a bit of rust and crap all over the bike. I picked up a new adaptor and after getting the cylinder head back from the machine shop I attempted to install the new adaptor. It doesn't fit!! I even removed the other stock adaptor to see if it will fit in the other side, no luck. The exhaust port is too big for the adaptor. I've double checked the part numbers, everything is right. Not sure how to fix the problem. Is my cylinder head done? or can the threads or opening be fixed? Hopefully I've explained this good enough to understand. This is my first triumph build so I'm learing as I go. Thanks.
