In November I was able to find a Laguna in the backwoods of Missouri. The guy who I bought it from gave me conflicting reports as to what the problem was. To this man's credit, he has worked on motorcycles for many years and knows a lot about bikes. He thought they're was too much side to side play in the crank and or the bearings were beginning to "sing".
After taking the bike home and cracking open the engine, everything looks to be real nice. The crank spins around freely enough, but I'm not sure if has really gone bad yet. There appears to be a teeny amount of crusty rust on the crank, too. There is side to side play, but I don't know how much is too much.
So, I've been wanting to rebuild the engine with performance crank so I don't have to rebuild it again down the line if I decide to upgrade. However, if I can't get the performance crank, I will settle for the stock one at this point. I just like to see the thing move!
