1987 Suzuki GS450L oil leak

External Since: Oct 14, 2007 Posts: 3

My recently purchased 1987 Suzuki GS450L has an oli leak it seems at
the head gasket on one cylinder. The bike still runs but on my last
ride it took a mile or so before that cylinder would fire. The blue
exhaust pipe would seem to indicate that cylinder is running hotter
than the other. This bike has only done 5k miles. Any ideas as to
what the problem could be - blown head gasket or is there an oil ring
there that could be broken?
