I guess leakdown and compression checks are in my weekend forcast. Maybe swap MEFI and/or Throttle bodies??

Seems odd one engine can burn 19 gallons more than the other one and no difference in performance and no soot on the transom. I still say the cross-over valves are open when they should be closed.

Sounds normal to me.

Mine have always done what you describe - before and after rebuild.

Hey Bobby, How you feeling? So sorry to hear about your accident.

I smacked the chit out of my mechanic and cut him off on the
Bud Lights. That'll teach the ratbastard to pay attention.

Take care.

In Chicago this week for PackExpo.

Dragged the Cig home Sunday for the winter. Had a nice ride Sunday, ran up towards Point Lookout and then back to Smith Point but it was a bit chilly.

Hang in there and take care.

Any obvious things/areas to check? Thanks
