What else could the bogging be caused by?
Seems like it is not getting fuel to one cylinder. have checked fuel pressure all is good.
Sometimes it runs like a raped ape and then it wont go over 35
try to isolate if it is fuel, spark or compression issue. make sure the whole fuel system is working and not plugged. Check compression both cold and then hot. Check all electrical connections. Make sure they are tight and moisture free including grounds. SOme guys end up finding a broken or frayed wire somewhere in the system. Check the stator using the following how to videos I made. also, unplug the 4-prong connection to see if there is something else that is effecting the electrical system. Unplugging the 4 way bypasses all switches including the tss. Just shut it off by choking it. Did you check clutching components? Did you check for a broken spring ect..? Does it just bog or does it backfire to? check all of these things and get back to us on what you find.
