Mono tubes would do the trick but expensive. Intiminators also work well. Oil change would also help. I added prog. Springs and new HD type E juice. Maybe not the best option but way better than stock (total less than 100.00) 2010 fxd

 

you might try a little lighter weight in the saddle. i was up to 290 and dropped down to 250 and it helped a lot in my control over the bike. hope to lose about another 40 lbs. with the front brake having the most stopping force, isn't it designed to shift the weight forward when the brake is applied. if you're bottoming out, guess that would be a bad thing. hope you solve the problem. i'm 61 and at that age where its a pita to lose even a pound. not easy for sure.....besides, i like beer. not being a smartass, just found it to be true.

 

You must be confused. I(the OP) weigh 180lbs!

 

Oh, I've had a few rider courses in my 44 years of riding. A few racing courses during a 12 year racing career as well.

Perhaps you should get 'thee' to a physics course.

 

The two extremes of weight shift: The "stoppie" where the rear wheel leaves the pavement under braking force from the front wheel and all weight is carried by the only tire in contact with the ground, the front tire.

The wheelie: when under acceleration, the front wheel leaves the ground and the entire weight of the bike and driver is on the rear wheel. Still no such thing as weight transfer?

A spring in compression deforms to a certain length when a certain weight is applied. The only way to further deform the spring is to apply more weight . Hence, when stopping, the front spring compresses and the rear spring extends directly demonstrating wieght transfer. The suspension springs could just as easily be springs in a scale, you know what happens to a scale as weight is added and removed.

 

I recommend 15w Bell Ray fork oil it's the best on the market. You can also add preload to the springs. I used a 1" piece of pvc the size of the springs to increase the preload.

 

I'm going to try the Progressive 1" lowered front springs and Belray 15w oil first. If that doesn't satisfy me then I'll add the Intiminators. Sound like a good plan???

 

I would go with racetech springs over progressive!

 

The problem is the 1972 suspension on these bikes! Solutions vary by effectiveness and price. Heavier oil will help dive at the espense of ride. Intiminators help a bunch as do racetech emulators etc. I have no experience with monotubes.

...and weight transfer is a real thing for those that are confused!

+1 on Racetech!

This has been the single best mod I have done. Completely different bike now. The best thing is it's tuneable and you can change the height from 0" to 1" or 2" drop with the springs included in the kit. Man I wished I had done this on my others.
