Default Lots of travel in forks!

When I brake or accelerate my forks travel a lot. I don’t see evidence of blown seals, assuming they are oil dampened. I’m new to this bike, 06 Dyna Wide Glide w/10,000 miles, so I don’t know if that’s normal travel or if I need to rebuild. Can someone weigh in on this?

How much do you weigh? Typically a bike is sprung for a 14 year old adolescent so if you are man sized you'll need to re spring it....go to race tech and type in your info and see what the spring rate you need is....I'd suggest both the springs and the gold valves...you'll then probably need rear shocks but stock fork spring rates are stupid low....I just did my 18 SGS and stock rate was .72 so with my weight and riding style I needed 1.3 springs....dang near twice the rate.....you'll be happy you did...

I think the first thing would be to determine what the oil level in each side is. It's possible that either or both are very low or not the same. You might not see any signs of leaking seals because there may not be enough oil left to leak out.
If it's not something you can do, get a qualified tech to service the forks to factory specs. It's a good starting point, before you start modding your front end with pricey parts.

The first thing most Harley owners throw in the trash are stock exhausts.

The first thing Harley owners SHOULD throw in the trash is the suspension on both ends.

No oil in the forks could certainly be the problem. It wouldn't be the first time I've seen that.

It's not just Harley riders. It is most people that ride motorcycles. Spend money on noise and show instead of what will improve the ride the most. Harley also has a habit of using mile long springs with heaps of preload. This will give a soft springy ride.

You can drain your fork oil . Measure it to Ruel out a leak. Fill with HD performance fork oil to tie you over until you upgrade your suspension.

I have a set of 49mm Gold Valves for sale in the classifieds if interested. They will make a huge improvement to the performance of your front end.

My buddy just bought an 04 superglide and the front end was diving worse then normal. He bought new springs and when we changed them found almost no oil in the tubes.

Brake dive is mostly a damping issue. Former owner may have changed oil to a lighter viscosity? Not added correct amount? Put in lighter springs? Anyway, address the damping first.

Subscribed. New to me 2008 Super Glide Custom feels the same way. Seems to work okay; but it doesn't take much to compress them. Does anyone know, or remember, if the were like this new?
