Here is a link to my 92 resto thread. The motor is out of the bike at the moment and apart on my workbench cylinder and head is out to Carl Bartlett.

Also there are lots of companies that make great pipes for the lt250r. Shearer, ftz, dynoport to name a couple of the best, there are also some other names that may be coming up in the future. Aeen also makes a nice pipe.

Your bike has an FMF pipe, it is the correct pipe for the year depending on the exhaust flange that might have been your issue. And yes the lt250 pipes are tricky to get in and out of the frame
