Tuning help
ok I have 2003 heritage classic
it has been up graded to a 103 stoker. 95 jugs and a jims stoker crank and a super E carb 585 cams and dynatek Tc88 ing. Set at 32B and 6000 rpm. I thought this was a good setting but it ping off the line and at wide open throttle. Not sure if timing or carb is lean. It seam the low side of carb is very rich. Acts like it loads up after a short idol

Always do timing first... Back it off. If you are too lean you'll get a cough out the intake.
Make sure the enrichener is closing all the way. You should be able to lean out the idle with the mixture screw. Intermediate jet should be somewhere between 28 and 31... The 29.5 Always seems to work well in the E for me.
Turn off the accelerator pump when jetting the intermediate. You won't be able to whack open the throttle but the bike should run fine at slow throttle openings.
Hopefully you are running a decent exhaust. Drag pipes can be an issue.
Still have problem? Compression check is good. then I'd toss the ignition and buy a DTT.

Roll on and WOT ping. Turn down your ignition. Most will have several options and they seem to run in pairs. With both having same max timing but one with less aggressive ramping. Max timing seems to affect WOT and aggressiveness of the ramping seems to affect roll on.

Ok I'm working on my bike and I am having a prob with pinging on wide open throttle. I have set timing back to 32B from 34b. The carb has a .080 main jet. My ? Is should I go up on main or should I go down one more step on the timing to 30B. My exhaust is Vance Hines 2 in 1 pro pipe. Ing is TC 88 dyteck
thanks for all the help

Sounds like your compression is off,, It should be higher. Did you check with the throttle wide open? Cam timing off?
An 80 main is likely too large so back the timing. Pics didn't come through for me..

yea i I did not tie open throttle when I did Compression on motor totally spaced it so compression could be higher I thought the 80 was awful fat too so I will try backing off time in a little bit more I just picked up this bike he had the Aceloratortor pump way too fat to so I leaned it back so I think that it's a time issue but thank you for all your help

you need to know you intermediate jet size too, i have found that with the super e and a V&H pro pipe they tend to like the 31 slow jet better,,,like max said, tune your intermediate circuit with the pump off, then once you are good there, adjust your pump shot,,,,,you need the timing set up too, sound like you may need a less agressive curve,,,depending on your compression, you may only need 28-30 for max advance, but you need to test to be sure,,,,power output tells you what it wants, better to do it on the dyno then confirm on test ride.
