Need help!!!
Hey everyone, I have a 2001 heritage softail with a SE120R and a SE CV51mm carb. I want to change the cams out to the woods tw-408-6, and have bobby woods rework my carb. should I do this or not?
Thanks

Get the bike on a dyno after cam install and dial in that carb and timing. If it were me, I would likely pull the cylinders and bore .010" OS to true up the bore and install new pistons like JE or CP.The key to this, and I cannot stress it enough, is to have a very good spot on tune. Get her on the dyno and dial in the carb; partial throttle is very important; that's where the motor will live or die.
Do NOT use a SE clutch, that will kill you. Pro Clutch is kind of chintzy. Get a Bandit Sportsman.
Decent exhaust will play into this in a big way. Don't know what exhaust you are currently running but a decent x-pipe like the Fuel Moto or V&H Power Duals and some Crusher mellows from Kury, Jackpot or Rinehart; Or... go loud with a set of D&Ds or an older thunder header.
More than you asked for but cheap information.

I edited my previous post with some details. DTT ignition is good. Custom ignition map or dial settings? If dial settings, where are they set?

Check the dials for initial timing and advance curve; too little or too much timing are both bad. Start at 2/5 and advance initial until you get some ping and drop back one setting, then do the same with the advance curve.

Just saying that you need to know what your ignition map looks like and get the timing in a "happy" place for your motor to avoid risk of damage.

Understand, I run a custom map on my all bore 107" motor in my '02 FLHT. You indicated that your settings were "factory" settings which indicate, to me anyway, that you don't know what your settings are. I experimented with a variety of settings before settling on 2/5 as the best all around setting for my motor. I downloaded the 2/5 map and tweaked it a bit, mostly the WOT settings to add a bit of timing and left the partial throttle settings alone. The motor makes 122TQ/110HP and runs on 87 octane fuel. Mileage is not great at 38mpg but can't expect much better from a carbed 107" motor making that kind of power and is ridden aggressively.

Agree with your recommendation to start tuning at 2/5 position on initial and advance dials.
