I took the connector pipe that goes from the head pipe to the muffler and replace it with a 2.5"piece of stainless steel flex pipe , I cut 1.5" of the end of the head pipe cut about 3 " off the muffler welded in a piece of 2.5" pipe connected it together, work's good no clearance problem the trike sounds so much better is so much cooler.
The original connector pipe goes from 2.5" to 1.5 inside diameter, the exhaust is just stuck there trying to get out . never found any body to do a tune I got a tune from Dyno Jet Then did 4 auto tune's it runs good now, spark plugs have a nice light tan color, ended up wit a 128 11.1 compression screamin eagle head's screamin eagle 64mm throttle body 5.5 injector's redshift 472 cam stock gutted head pipe wrapped the exhaust S&S race muffler's .
there's a swap meet coming up in april if the dyno guy is there I will get a dyno run to see what the torque is ? it is rideable at all speeds the woods 408 cam does not work in a trike! The power is crazzy , getting around 30mpg Now Im HAPPY I will try to post some pictures this week end .
