Apparently Fuji San from Suzuki had a similar sake situation.
Lady with a GS1250S Bandit called me yesterday. Couldn't sell her bike as she couldn't find the engine #. This 2013 model with only 3,800km has already been thru 2 dealers in 2 different states.
Dinky di! There was no engine number at all, just a blank space where it should be. Last dealer to sell the bike has a please explain headache to deal with.
Oh, the number goes on the back of the crank case right in front of the swingarm, will be a big job to remedy that one.
