2003 TC 88 FXDWG cam question w carb
I did my chain tensioner inspection, at 20K they were looking pretty worn, especially the inner. So I decided to swap out the cam chest for a Feuling OE+ kit, cam plate, oil pump, lifters with new 525 chain driven cams. I went chain because Of the possibility of crank run out being off….after seeing these horrible original chain tensioners who wouldn’t doubt Harley’s quality. I installed Feuling one piece push rods instead of using the adjustables that came with the kit, wanting to avoid being out of wack with the adjustments.
All in all not a horrible job to do. First start though was rough. It absolutely refused to start, I pulled the covers off to make sure I was timed right….and it was. It would only start if I rolled back the throttle slightly, then would back fire if I let it idle. I’ve got the idle set way up from where it was. It sounds flat on acceleration, but as soon as you get above 2000 rpm she pulls like a beast! I’m thinking the jets on the carb are way off now, I honestly didn’t think it would be that bad though as the cam’s specs are not super radical. Does anyone have a good starting point for jetting the carb? Or am I going in the wrong direction? When I bought this bike I thought having a carbed bike would be do cool. Wrong! I just don’t want to spend the rest of the season wrenching this thing…..
Feuling 525 cams
stock valves
stock pistons
stock Kehlin CV carb with 2 jets up from stock main when I did pipes but stock slow jet
S&S stealth Air Cleaner
S&S Grand Nationals slip ons
thanks in advance!

Thanks for the info. This project started out as a tensioner inspection. It’s kind of crazy what I’ve spent on this lol… but I hear you. It’s a nice bike but kind of small for me so I couldn’t see myself upgrading it to a 96 or so… The cam set I really wanted was S&S’s 509, from what I’ve read it’s got some great torque from the start. Oh well, next bike
