Check out my fork springs!

surfish95747
Hey guys, I was pleasantly surprised to see that my springs were still very serviceable. The manual says the free length should be 20", and serviceable length is 19.4". Mine are at over 19.5, closer to 20". Cool.





I would just like to thank this forum for all the help and advice everyone has been while I've been putting this thing back together.

Thanks for the kudos. Now just for fun, do you know what that little black diamond is for at the 19 3/16" mark on the tape measure?

It is for engineered lumber measurements. However most of the time we space joists and such at 2'-0" o/c. Only if there is a high weight load above do we space at 19.2"

And just some friendly advice, since you have everything apart, drop in some progressive springs. Worth the extra cash.
It's only illegal if you get caught.

If at first you don't succeed, use more lighter fluid

So, with the progressive springs, as an amateur rider, will I notice a difference between my stock springs that still have life left and the new progressive springs? Thanks for the advice!

I have heard nothing but good on the progressive springs, however I have never used them myself yet. That black diamond is for carpenters doing framing. It is for installing studs, floor joists, or rafters, when you do not need the strength of 16" on center, but need more then 24" on center provides. In all my years of being a carpenter, I have only run across its use once.

Haha! That was a good one!

I think I paid about $75 local for my progressive springs for my 76. Night and day difference even when just cruising. Large bumps don't feel as severe. A series of washboard no longer makes the front end feel like it's wanting to fly apart. Even just barreling down the highway felt smoother.

Im cheap. And I'm usually the first in line when it comes to reusing good, stock parts. But Truck is right. Progressive springs are great.

I always wanted to go progressive out back, too, but ended up selling the bike.

Im glad the forum has been helpful to you. And I'm glad to see you really taking the time to do the bike up right. Props right back at you buddy.

Thanks shiny.

Unfortunately, My budget doesn't allow for new springs right now, however it is on my short list. If my stock springs were unserviceable, than they would have gotten first priority, however, my electrical system is draining batteries like my drunk uncle at Christmas! Once I get these forks back together, I'll put the front end back together, sync the carbs and then test the electrical system. Hopefully all I need is a new regulator/rectifier!

I was having the same electrical problem. Cleaning/checking connections helped a lot. Before replacing parts you should test them to make sure they are bad.

Will do Truck! Thanks. Ive got one of those digital voltmeters, I was reading that I need a different meter to test the alternator by hooking it up to the battery? I am so lost when it comes to electrical systems and wiring! I'll just follow the manual as closely as I can.

Well, a typical voltmeter is fine for checking battery voltage with the bike running. Nothing special needed.
Just check voltage before starting bike(full battery of course), then start and rev to over 2000 rpm and check voltage again. Need to be over 2000 rpm for the bike to really start charging. Should be over 13.5 volts, but generally no more than 14.5.

As Truck said, clean the connections, better yet replace them or solder the wires, if you are inclined. I wouldn't just in case you need to take things apart. These connectors, truth be told, kinda suck. New connections can make a big difference.

Also, for your springs, you can get a piece of pvc tubing and cut an inch long piece to go on top of the spring. Pushes the spring down to give it a bit more life. And pvc is cheap. Tide you over till you get progressives.
The ride IS the adventure. The destination is just to get gas!

Thanks re-run! I'll be checking that all as soon as I get my forks back together and the bike off the stands.
