How do I slide forks up to fit clip ons

[273nic]

Hi All,

picked up a CB750 K2 just 2 days ago and started big pull down to overhaul.

I need to know how to slide the forks up through the trees to fit clip ons.

Thanks for your help.

The trees clamp on to the fork with a bolt. You'll see the bolt at each seam where they clamp. Put the bike on the center stand then jack the front tire off the ground before you loosen the bolts.

Thanks mate, are they the bolts at the bottom front of the headlight ears - or at the bottom/side of the fork just above where fork joins the wheel? Also when you say jack up the front wheel how would you do this, jack the bottom of the fork?

Thanks again

you are only jacking up the front enough to take the weight off the front suspension, otherwise when you loosen the pinch bolts it can slide uncontrolled all the way down.
 It maybe easier to put the bike on its centerstand and put some weight towards the back, or have a mate sit on the back of the seat to raise the front. you just need some daylight under the front wheel.
 Here are the 4 pinch bolts you are going to loosen, once you have the bolts loose you may need to GENTLY spread the yokes open with a flatblade screwdriver or such.



Now that said, sliding the fork tubes up in the yoke also lowers the front end, reduces your suspension travel, and changes the geometry, you can go too much and the steering become unstable! Tank slappers are no fun. You should also go exactly the same on both tube, not eyeball, or ruler close, but within a couple .001" on a set of vernier calipers / Mics
 Clip-ons were designed go under the top yoke and you not have to slide the tubes. They make different height... but that will mean not using the factory headlight ears, the make aftermarket ones that are from $15 on up depending on how nice you want.

If you do slide them you may want to lower the rear as well to keep the changes less than an inch difference between front and back. Although I LOVE the looks of this CB750, "Anvil", here is an example of too much. There is virtually no suspension travel left because the fork tube are slid way too far. It may look Cool and mayeven be ridden, but not in the real word where I live, pot holes, railroad tracks, even speed bumps would bottom it out and I GAR-un-TEE the rake / trail / catsor numbers are crazy unstable.

Wow, no front fender, pods on CV carbs, insane lack of suspension travel....

That is a show bike if I've ever seen one.

That said, maybe it's just unfinished?  It also doesn't have a seat.

Lets not go into scared child mode so soon grass hopper.

As for the seat all you really need is a piece of black 1/2 inch closed cell foam.

He's removed all but what looks like 2 inches of travel.  How would you deal with that?

There are quite a few motorcycle forums on this vast internet. Some of them are friendly,some of them are not.This is one of the friendly ones. And it will remain that way! The name-calling of other members and putting down of their opinions is not going to happen here. Everyone is encouraged to share their views,but in a cordial and respectful manner. Teasing one another can be fun,just so long as it's done in a friendly way.

Thanks for the detailed instructions and photos made it much easier.  I''ll give the slide a try to see how it effects travel etc and also consider change of ears as an alternative.

Cheers

I feel partially to blame for showing a particular bike, eveyone has the right to do as they please to their bike... but wanted to show an example of what I consider excessive.
Yes, it is a real bike, Anvil Motociclette is it the name of the Italian shop that built it and others. http://www.anvilmotociclette.com  This particular bike is SELVATICA although partially unfinished as shown here, it is ridden. I am sure the rear pit stand compresses the front end and aids to the illusion. But it gets my point across.

Damn, I wonder how it runs/rides? Would a lot of pre compression or super stiff springs fix the bottoming out?

It sure looks good anyways.

oh, and I've learned to selectively ignore some of lucky posts. I chalk it up to him being a grumpy old man
