Lifting Hydra Glide Fork

#1

Post by Pan58 » Tue Mar 01, 2011 11:16 pm

Hi everyboby

I would like to lift the front fork by 2" with longer fork tubes on 58 Panhead Hydra Glide fork. Can I use the stock forks? do I need a spacer with the forks? Anybody has some experience about this?

Reason is, I dont't like to scratch with the floor boards in allmost every corner.

Thanks, Pan58

pan 58,

do you have the correct tires on the bike? might save you the trouble of extending the forks!

Hey Pan58,
If you decide to go that way I have a front end with 2" over tubes and matching 2" over cowbells that are new. The parts have never been run but are assembled on a fork I picked up. PM me if interested.

Mine had 2" over tubes when I first got it, so I also have a set of the 2" over cow bells collecting dust, I trashed the tubes. I like the stock look better...Mike

To answer your questions, you can use the stock lower legs, and you will need spring spacers on top of the springs. The spacers are nothing exotic, just steel tubing that fits inside the fork tube, about the same inside and outside diameter as the spring, and as long as the amount of extension, i.e. 2" over, 2" extension.
You will need to remove the dampers from the old tubes, and install them in the new tubes. Not a big deal, just a snap ring holds them in, but it would be a good idea to inspect them before ordering tubes, as they may need parts or replacement, depending on condition.

Robbie, if Pan58 isn't interested, let me know exactly what you have.

Regards,
John

Hi every body

sorry, I didn't answer. I was in L.A. over the weekend. Perfect bikeweather.

I have the correct front tire. That shouldn't be the problem. I have the 2" over tubes, the bells, even a 2" over kickstand.

John, thanks a lot for your advise. So I will grind these spacers and go ahead assembling the 2" over fork.

Wonder how the handling will be afterwards.

I think you'll like the handling, at least at higher speeds. Low speed handling may suffer somewhat, but not radically-- maybe not even noticeably. You are increasing the trail just a bit by adding 2 inches to the fork legs.

I went from 8" over, to 2" over, to stock, on my '50. Obviously, there was a dramatic change from 8" to 2", but none that I was aware of between 2" over and stock length.

John

Hi John

And what about the turns? With 2" over, is there a noticeable increase in "bankangle" before the floorboards hit the ground?

To be honest, I live in southeastern Florida, where the roads are mostly straight, and the speed limits and traffic on our few curvy roads limit the possibilities of scraping the boards. I have yet to scrape them with stock length tubes.
As far as tires go, are you running the original profile 5.00x16, or a modern 130/90? There is a significant difference in height between the two.

John

I'm jealous. I grew up in Western Pennsylvania, and drove over-the-road tractor-trailer in Germany for a little over three years, as well as riding in Europe while there. I miss the curves, but not the winters.

The 5.00x16 would give you more ground clearance, but the modern profile and tread design will probably improve your cornering ability.
If you are good with geometry, and know at what angle your bike drags the boards with stock tubes, you could calculate the increase in bank angle for different tube lengths.

Regards,
John

that's why i asked! if you fit the correct size tire your floorboards will live longer!

I read the Rider Hand Book. There they say, that the 5.00 x 16 tires were supplied as original tires for the Duo-Glide. These tires have the number "100" on it. This number means the ratio between hight and width. So I guess, the "100" tire is higher then the "90" tire. This should lift my Dou-Glide higher from the road...

john, I think that's what you mean?
