Good afternoon guys hope your all well
,I'm not very good with bikes but yesterday I was checking my piston through the exhaust port to see how good condition it's in and the threaded bolt that comes of the engine came off I tried to screw it back in and it wouldn't go in I'm guessing the thread is ruined
Are these meant to come off as I have another cylinder head and it looks like they are welded on and you just bolt on the exhaust I hope I explained this well enough I managed to use a bigger bolt and get the exhaust on just not the best fit but will be doing a full top end rebuild anyways
My question is where the exhaust goes on are the threads welded on to the cylinder head or screwed in as mine was like a 2 way thread one in to the engine and then one for the exhaust to go over then bolted on.
Cheers guys
