Kawasaki H2 750 1975 on 2040-motos

I purchased this motorcycle in July 2009 and immediately started restoring it with many NOS parts.  I’m an engineer by training and performed the majority of the work myself with the exception of some specialist services.  The restoration was completed in October 2010 

I've only put a handful of miles on the clock since the restoration due to a new family addition and work demands.  Everything works as it should with the exception of a carburation issue - the engine idles extremely well, but hesitates in the midrange.  Its something I just haven't had time to fix.

The motorcycle was fully stripped-down and the following work was performed:
