FS: GroupK 1390 big bore $1850
yea that price is right. here is some info.
Group K 1390. previous owner recently replaced the crank about 50 hours ago and did the rings. I never got it tuned to run full speed but the power was there. I was going by the forum and thinking I would see a higher speed number but I realized that goup k has a milder port then lowell. I emailed lowell and it was about 450 to have the cylinders done to give it the extra mph. It ran 73-74 bogging and cavitating.
will include the carbs, one has epoxy on it because one body cracked where the one bolt goes in. The carbs need to be rejetted without a doubt. But this is a steal!!!!!!!!!!
no exhaust manifold, that is tapped for the advent data tach.
