ok guys I have a good one for ya, I did some learning at sandfest with the banshee, I found my cutting out problem but still have another after fixing the obvious. when first dynoed it would be perfect jetting then at 7500 rpm go lean on the left, so we found the crank seal was leaking so I split the cases on the picnic table and put new seals in it. So next morning go dyno it again and pull 46.96 HP with perfect jetting but now it goes lean on the left side at 9500 rpm, you can drown the motor with carb cleaner and not find any air leaks but then again it dont lean out till 9500 rpm, I have tried float settings on that side as well as made sure its getting good flow of fuel to the carb. Has anyone experienced this or have any ideas on it, I have covered the obvious and know this could be fun to find. So the jetting question has been ruled out since it all shows perfect on the exaust analizer all the way on the right side but of course only to 9500 on the left
