i see the rake angle on the 07 has changed to 24 degrees, anyone know how the did it? - is it just new fork clamps? and i think they have re-valaved the forks - anybody ridden both setups? | ||

As far as I know, all they did was change to a progressive spring and the oil level. | ||

According to the 06 and 07 owners manual specs, both have 23.5 degrees of rake. Progressive springs were added in 07 which required an oil level change as well. No changes to valving were made, but the guide for setup was changed in a few places. I recently swapped in the '07 springs and it was night and day. The '06 springs in my bike were crap and would bottom out under brake dive. I could never figure out the suspension until I swapped the front springs and then everything else was easy to sort out. | ||

Oh crap I'm glad I read this post. I've ordered the springs from the dealer (over two weeks ago, still not in) but I didn't realize there had been a change in the fork oil level. Can anyone send me the new specc or changed figures in the manual? The 2006 manual says to add 9oz pump to feel resistance then add 90z more. Then adjust to be 4.45 in from the top of the fork tube.) | ||

I asked my dealer about the '07 upgrade and he said "if the forks are set up correctly, then you don't need the '07 springs" | ||

Yeah, I heard that they just had a bunch of progressive springs lying around and needed to use them up. | ||

I have the '07 fork springs and they do make a difference in dive (or should I say the lack of it) and it handles riding 2 up much better as well. | ||

I too would like the fork spring/oil update. I was thinking of going that route, I ride 90% time 2 up. 1) Do you need the fork spring compressor to dissemble & install ? 2) Forks off or can be done on the bike? Thanks,Dave | ||

Brake dive is my only real complaint with my Uly. Has anyone posted (or could you) post a project to upgrade to the '07 springs? | ||

"I asked my dealer about the '07 upgrade and he said "if the forks are set up correctly, then you don't need the '07 springs"" BS. The '06 springs sucked huge ass. I had maximum dive no matter what I did with the settings. So did several others I know. All we did was swap in the '07 springs and replace the oil to the new level and voila it handles like a dream. If you have an '06 with no dive then it was overfilled with oil from the factory or you weigh 50lbs. They changed the springs because there was a problem not because they "had extra's laying around." Now I have very minimal dive even under maximum braking, but at the same time it is more plush over my rutted dirt road as well as feeling more connected to the road. You do need the spring compressor and a oil level tool of some sort. Loosen the top nut before removing the forks, then remove the fender, wheel, caliper, and beak bolts. Remove the forks, disassemble per manual, throw '06 spring in trash or use on childs' toy as it was designed for, install new spring in place and reassemble per manual. Much easier to do than I was expecting, but you will need an extra hand to install the spring holder. Search for progressive springs topic and the new oil level is in there. | ||

Jmhinkle, which end up for '07 springs, tight or loose winds? I forgot...  | ||
| Teeps |
We discussed this before. I though we decided to install one up, one down to split the difference. If it makes a difference, and I doubt anyone here could tell, I would put the heavier end of the spring on the stationary side of the fork. | ||
| Birdmanrh |
A progressive spring does not know what direction it is placed, it simply is weaker at one end and stronger at the other. That means it will not matter if you put one end up or the other. | ||

Hyperpro progressive springs indicate they should be installed with the closer coils at the top. I'm guessing the Buell progressives are similar and should be installed the same way, but can't confirm that... | ||

Wilbers sez put the close coils up on a conventional fork. How is that for muddying the water  | ||
| Gotj |
It seems to me that the Wilbur's advice is consistent with Hyperpro's in that the close coils are both in the non-moving part of the fork. So when you hit a bump, there is less spring weight to accelerate. What am I missing, if anything? |
