I love your fearless attitude with do it yourself mods. I want to do the fork mod you described. I have already made some dogbones. Since I am not as fearless, but a true cheap bastard, I looked up stock fork springs online at www.zanottimotor.com (which I think has the best OEM prices anywhere) and the springs are only 14.33 new. That made my mind up to go and try your mod. Quick question, pipe nipples..like this

*image link removed*

or coupling

*image link removed*

you dont use the treads, right? Do you grind off the treads?

Thanks, Ray

Hay Badfish2,

These guys have done right by me so far for OEM parts, and they're a few bucks cheaper too.

This link will go directly to their 2002 FZ1 microfiche.

I glanced at it and I do like the web site set up. Zanottis web site is a pain, you have to have the yamaha fiche up to input the part numbers, but the few items i looked at (fork springs, cowling panels) were cheaper at Zanottis. But that might not be the same for everything, and I like cheap and good service. Thanks SO FUN for the site.

Badfish,

The nipple. Buy two a bit longer than needed,I haven't found a source for the exact length that was as cheap as a standard length of 4".

Then cut and hand grind to size. Treads are un-important.

I did Raven's front fork mod today. Everything was real straight forward. Since it was my first time digging into front forks I thought it would be a little more difficult than it was. The carbs are still out of the bike and there a few other mods to be taken care of before I'm back on the road.

Raven and everyone else,
Thanks for the help

There is another thread on the subject of an allen for the front axle.

Go to the local hardware and pick up two coupling nuts that measure 3/4 " across the flats.

One for the garage and toss one in the bike tool kit.

II had to wait around last week for my new rear tire (pilot pwr) to arrive so I preformed this entire mod. It was a huge difference; the bike is quite a bit more agile than before. I also replaced the front brake pads with EBC HH at the time and the front end dive is reduced allot (with the new pads I was expecting more diving). This is giving me more confidence to go deeper into the turns. The whole bike feels much more stable even in the straights. I do not doubt that reworking the forks with different valves and an expert helping with the spring change would be great, but for the small amount of time and money this mod is so worth it. I also have a better understanding what is inside my forks and a sense of accomplishment (should have had the Discovery Channel filming my "Fabricating skills"). Plus I was amazed on how filthy the fork oil was at 9K miles.

Yeeee Haaaaaa

Thanks for posting how it worked for you. I was so pumped on how well it came out I just had to share it with the board.

But I wanted to hear if some one else found it as easy to do and how they felt it worked for them.

I'm so glad you feel it was a good improvement for the time and money spent.

I know I was amazed how it transformed the total feel of the bike with so little effort.

That stock oil really is not as dirty as everyone thinks. It is a molibdinum disulfied based oil (actually very good,just not the correct wt) and stinks even when new.

Glad it is working for you and that you 're happy with it.

For anyone on a tight budget or just wants to improve their suspension themselves for cheap it is hard to beat.

Thanks again for giving it a try, and posting your results.

No, Thank You for showing me the way.

I knew about the smell of the fork oil may not be a good indicator, but I had quite a bit of black sludge. And the new fork oil was bright and clear.

raven,
the flat stock you used for the dog bones is thicker than the stock bones, did you have to replace the mounting bolts with longer ones? Or does the nut thread fully onto the original bolt with the thicker bones?

Broke & poor,like me.

No worries,the stock bolts will work just fine.

Full thread engagement as required,with just a bit to spair.

I measured everything up before making the first set.

Raven,
I'm still not sure how this would work for me. I like the idea but need to settle a few things in my mind first... the main problem being a 'paint-shaker' thing my front end is doing at low speeds (25 to 50 mph). The front jumps up and down rapidly.

I don't think it's the tires. It started with a set of BT012's, I thought it was the tires and just decided to deal with it until they wore out. Well, the day came and I replaced them with Michelin Pilot Roads, and the paint-shaker persists, perhaps even a little worse. Had both installs done at a shop and I'm sure their balancing is fine also.

I'm thinking a comination of bad front bearings ( I'm pretty sure they are bad) and I need to change the fork oil.

Now I can do both of these myself. But being only 150 lbs dripping wet I'm not sure the spring mod would benefit me. Perhaps I'd be ok just dropping the trees a little (5mm or so) since they are currently only about 1mm below the top of the forks.

I'm also not sure about the dogbones... I'm only about 5-9" or a little shorter... seems like it would put a little more weight on the front but may be a little extreme geometrically for my short stature.

Do you have any thoughts on how this mod might be done differently based on the fact I'm short&skinny? (maybe I should change my login name! ! !)

thanx

First,the front shaker.

Dude,I would bet money they did not balance your front tire.
If the bearings were that bad you'd have been on your a$$ long ago.

Pull the rim and tire and take it to have the balance checked or do it your self.

I use two 5/8" ID bearings, a piece of 1/2" aluminum round stock 12 " long and two jack stands to hold the bearings.

The springs may be OK for your weight ?????????

I'd leave the springs,change the fork oil to 2.5 wt,but fill to my spec. level. You'll get a lot less fork dive under braking.

Yes,drop the forks a bit more,and try it. You can always pull the spring and shorten it.

On the rear,the stock spring is still a bit light,so you could try the dog bones anyway. They R & R in about 10 minutes or less.

Just start with the preload on the rear spring backed off about 6 - 8 clicks.

Worth a try.

Woooo,

Made a mistake on the spacer diameter for the front.

NOTE: The correct diameter is 3/8"

Should be 3/8" diameter X 4" then ground down to 3.602"
Sounds off,but the 3/8" nipple is large enough to fit over the damper rod and make good contact with the lock nut.

Sorry about that guys.

The diameter is not critical,it just needs to not slide over the dampening rod to fork cap lock nut.

Raven,

I tried to use a 1/4" fitting when I did your mod but it wouldn't fit over the damper rod....ended up using a 3/8" fitting and placed a washer between the new spacer and nut. I really don't see any reason to take it apart and mess with it again but would like your opinion.

No worries. I would have done that for sure.

NOTE: (3/8" is the correct diameter.)

It's just a spacer. The 3/8" spacer I used was a steel threaded

pipe nipple.

Raven,

I received your dogbones in the mail yesterday and will be installing them post haste. The bike is going to be on the road today and I can't f***ing wait. Even with a mild winter it's been a long time coming. Thanks for all of your work on this. I really do appreciate it. Now that the we're on the cusp of the season we need to try and get together for a ride sometime.

Todd,

I went and looked at those pipe nipples and I think I ended up using 3/8" as you did.

Wish I had taken pictures.

I'm scrambling to get my bike back together.
New LEDs,hugger,fender mods and the like.

I'll send you a pm when the group is getting together. Soon I'd guess.
