I had the tw6-6 in wifes '10 tri glide, and it ran good but decided to change oil pumps about the time the tw555 cams came out so i instaled them and it runs even better. I use the thundermax/autotune, great unit. If you used adjustable pushrods you might want to readjust them to see if it quiets down.
The tw6-6 cams i put in my '09 fat bob and they are great for that 96".

Thanks for the info.
Initially, I adjusted the SE adjustable pushrods (24 TPI) to 21 flats as recommended, but there was too much noise.
I increased the from 21 to 22 flats, and the noise reduced very much, but there is still some.
I will try to increase a few more flats to see what happen. I still reuse the stock lifters.
The change that I concern most is the MPG has gone down bad.
I need a new map, but it is hard to get from Fuelmoto. I am waiting for their email.

Best thing to do is just call Fuel Moto. TW6'S are fun cams! You should be able to get them quieter than stock.

I agree,. I think you need to start over on your adjustment, dont keep turning them down. You need to have a feel of where to start adjusting.

Lossen all the rods up and turn the engine over(with spark plugs removed) until the cam lobe for the rod you are adjusting is at its lowest point. Adjust the rod out untill it is just snug (no freeplay). Now adjust the rod out for .120 t0 .130 of travel. to get the number of turns we use this calculation: 24TPI equals .042 travel at 1 full turn of the rod. Lets take the nomminal travel of .125 and divide by .042. that equals 2.976 turns of the rod to get the correct travel. So now adjust the rod out 3 full turns (forget counting flats) and you should be good. Repeat the process for the other three rods. You can be a little more or less on the three turns.
Hope this helps.

Yes, that's the procedure that I have been doing, start everything again for any adjustment. My problem is I have read many different suggestions, in terms of turns, or flats, so I don't know which one is the best one to start with.
I picked the 3 turns, then 3.5, and the last one is 3.6, but I never try the less than 3 turns set up.

I have a pair of these going into my 96 and I am bolting a pair of worked heads on too. That dyno sheet above doesn't specify if the heads are stock. If so that means my combo should be be good for 100 square.
I just got really excited and subscribed

Most say that the 6's don't even begin to come on until 2900 or so..
I was gonna go with em' and had em' but ended up going w/the 525's that I have now. Couldn't be happier. Cams come on @2000 and go out to 5900.

Sorry!
I really don't mean that. I was thinking about the previous email, which I sent out on 01/01, and got you response on 1/13. For sure, I know that you were busy, and I have bought the power package from you for more than a year.
No problem at all! I always admire your super service.
Thanks for your helps.
Nick
