Question Final Mods Poll

Ok guys, I have done almost all the mods Im interested in.
(sorry not doing pipes I prefer the look of the stock ones)

(mechanically Ive only done the chain/gearing change and the flapper mod)

The only 3 left are PC III, front fork springs, and ohlins rear shock.

The fork springs and ohlins are gonna be a little pricier so Im asking, with the suspension enhancement is it really night and day or is this one of those "you should have bought another bike" mods where its just spending alot on diminishing returns.

Spend the money and enjoy the ride, IMO it was worth every penny I paid for the Ohlins

Mainly what I want from the ohlins is if I push down hard in a turn, the back end wont protest. Will I get that?

And so much more. After setting it up correctly, you'll simply forget it's even there! Totally worth the money and they hold a strong resale value.

Fork springs alone are not worth the money in my opinion. What really controls the front end dive under braking is the damping so without changing the valve spec too you really are not gaining very much on the 919. New fork springs by themselves may get your sag numbers closer to optimal, but the compromise then becomes the way the bike tips into the corner while trailbraking. When you do the fork springs and the valving at the same time there is no compromise just overall improvement in every aspect Compliance, Traction and Geometry.

Then Ill do fork springs and valving at the same time. If I can find someone in Sand City to do it.

Or do fork springs and f4/f4i fork conversion.

The valving on the F4i forks is no better than the valving on the 919 forks so just changing springs on the F4i forks is going to leave you with the same damping problems.

I'm just asking here, just asking. Aren't the stock 919 springs progressive so you'll be riding way down in the stroke and get a crappy stiff ride? I put .95's in mine with stock valving and 5wt oil. It rides higher in the travel and imo works substantially better.

It's a vacuum operated flapper which opens when rpm reaches a certain point. Only thing it does is keep noise levels down to pass regulations and makes the power band more evident. Flapper mod makes the power delivery smoother.
