2004 Harley Fatboy 88b motor. Bike was running fantastic was going to do my spring maintenance found that my inner tensioner shoe was shot. Got the whole kit to upgrade two hydraulic tensioners everything went great new cams them went in perfect. New lifters new justable pushrods everything went in beautiful I put a new plugs after everything was said and done I went to fire it up I hit the button it fired up immediately. What it does now is at idle and if you give it just a hint of throttle there's a miss and if you're riding and you let off the throttle there's a miss like when you go to downshift. Otherwise at Mid throttle there's no miss it runs beautiful. The new plugs I put in for them iridium plugs. I thought maybe that could have been a problem so I bought another set of NGK plugs gapped them to 40,000 and 18 foot pounds no difference. My question is what could I have done? Or mist? Thanks in advance. So I just took out the coil in checked resistance the coil is good. I also checked the wires they are within spec. As I was thinking about it when I replaced the pushrods with adjustable pushrods the Screamin Eagle pushrods wanted two and a half turns from zero Lash I did that but if I was off a little bit on the front cylinder could that possibly caused the problem?
