    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • This forum is for placing reviews for parts, accessories, gear and service as it relates to your GS motorcycle. The key here is "GS Related". There is a bit of latitude here but we don't want to see a review on Maytag washers just because that's what you use to clean your riding jacket in.

    Keep your review as factual as possible and please refrain from personal attacks. Posted articles will be reviewed by the Editors and may be removed at their discretion.

    So let's make this a useful addition to the forum! A special pat on the back goes to Hap Call for coming up with this great idea.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

You sure you ordered the RIGHT front springs?? The 1100s use 1107s... the 1108s are a full 2 INCHES LONGER than the stock spring for the 1100....the 1106 are also longer, but only about an inch and aquarter... Ask Posplayr...he put the wrong ones in his...had to stuff em in there with no spacer..and the bike doesnt even so much as shift its weight off the stand... Ooops (tho, my fat ass will be getting 1108s next time.. I am running 1107 and have my preload adjustement all the way up)
 
Where is the best place to get progressive fork springs?
Ten days? God I could drive there and back in that time.
I've gotten parts from Japan in two days!!!

According to the progressive website they are correct. If you take the progressive spring and add a 4" spacer(as they recommend), they are the same length as stock. Don't forget I have an L model.

Dennis Kirk, for example, wants $84 plus 7.99 shipping for the fork springs. Delivery from them is about 3 days. Since I have not had much time to work on the bike, I was not concerned about the wait. I'd rather save the money.
 
FYI the 1108's fork springs will fit

Good point. I just get hacked about ridiculously long delivery times. I know what you mean about time, and I'd like to have the part waiting for me rather than the other way around. Thanks for the ling and the part numbers, that's probably the same things i need. Could try telling them you didn't get them wink wink! just kidding
 
Google up progressive's website...they'll show you specs on all their springs for Zook...You want at least a LITTLE spacer in there tho...

Why four? I mean if you lucked out and got the exact right length and sproingitude to give you the proper sag would there still be any benefit from running a spacer?

My new favorite word: sproingitude. :D

Thanks, man! It'll go into my mechanical vocabulary right next to gription and burnyness.
 
I wanted to give an update on the progressive shocks and fork springs. It's been about 500 miles since the upgrades were installed.

For the forks, I used a 4 inch spacer per the instructions, 15w fork oil, 6psi air pressure. Sag in the fork is 1.5" inches with this setup.

Rear shocks using the 105/150 springs, preload is set on 2nd notch from bottom.

New tires are Pirelli RT66 100/90-19 front @32psi, 130/90-16 running @34psi

All I can say is..WOW what an improvement. The rear of the bike feels like its on rails. No more fishtailing at high speeds. There is so much more road feel in the front end, not overly sensitive but you can feel pretty much any ripple/rut in the pavement. With the suspension mods and the airhawk seat cushion, I can actually say "the bike is now fun to ride".
