Putting weight in certain areas of the weight will add or decrease engine braking. I like to keep most of my added weight to the tips of my weights for less engine braking. (weight on the tips more equals shifting faster and holding the weights out longer).
Profile of the weights is critical also, plus what springs to go along with the weights. Less spring with heavy weights will make engagement very low and engine braking is basically gone. Use a stiffer primary spring and less weight in the primary clutch and your primary will have all kinds of engine braking.
@jonlafon1 - What primary spring are you running now? How are your weights set up?

I Asked the tuners last year in a thread about tuning more engine breaking into a flash, but it never gained any traction. I'm sure if there was enough demand for it they would get it done. Maybe just start up a new thread directed to the tuners and see how much interest there actually is

I really like my TPI orange secondary, orange primary, glide washer, TPI roller setup with the stock weights running @ 8900. Great backshift and not much belt dust with this setup and have seen 122 on the speedo on the lake. The stock setup on my friend's 50th seems very lazy in comparison and will not run quite as fast on the big end(118 speedo) I finger walk him above 110. His rpm's are about 8600 which is probably the difference on top end. As soon as I break in and hit 9000 or more I will switch to the heavy hitters.

Interesting.....I run orange TP and a 33/35 currently and stock primary setup last weekend, and the EB was NON existent.More helix angle and the Orange thunder secondary spring and you will damn near go over the bars if you completely let off throttle. I found myself having to almost ease off the flipper as It would back shift like crazy. Conditions surely played into this some also as the base was thin. In five hundred miles(ONLY thing different then my end of year set up was Thunder orange secondary spring) I might have used the brake 3 times.
Sitting at 3100 at this point
Not sure the weights are the factor.. I run the thunder weights, and eco trail tune.
I need more for sure...hate using brakes.
Hoping my STMs and dalton spring will get me some EB....

Dan, you will find it. I have read a lot of your posts. Which takes time! Your going to have to play with clutching,and your a details guy. Don't sweat it. I have set up listed and feel it back shifts like crazy. I know it sounds crazy. But I feel it's the helix and weight placement on the heavy hitters. More angle means less back shift traditionally correct? I don't have a clutching book. I go by my speedo and butt feel. So not sure I have it right all the time.Interesting.....I run orange TP and a 33/35 currently and stock primary setup last weekend, and the EB was NON existent.
