750F fork alignment
« on: September 05, 2010, 01:15:29 PM »
Hello forum friends,
I have some photos to share and sorely need some advice.
My 1976 CB750F front-end is not aligned.
I welcome all suggestions to resolve...thanks
Mr. Mac

A little more info would be awesome. Did you crash the bike and the forks are bent? Is your fender crooked? Did you just buy this bike this way or did you mess it up? Im not sure what is wrong just from looking at a few pictures and a vague title like "Fork alignment".

Thanks.
The bike has 2900 original miles, was not crashed that I know of.
Purchased recently and the prior owner swears it was fine when he shipped it to me.
Top right fork tube looks out of line with the bottom tube. The fender is a little crooked.
When viewing from the front or when riding, you can see it is not tracking straight.
It doesn't look right to me or the guys down at the local Honda shop.

Loosen the top clamps straighten everything up and do up tight. You would be surprised at what people ride without noticing any thing wrong....Get someone to help hold everything straight while you tighten the clamps up.

When I rebuild my forks I leave the springs out and mount the forks and the front wheel.  Then I raise and lower the wheel to feel if there is any binding.  Its important to have the wheel mounted correctly.  Next I install the fender/ fork brace and recheck.  If the wheel goes up and down without binding you are almost done.  Mount the brake and adjust and recheck and you are done.  Put the springs in and button up.  Yeah, it's a bit anal, but bike shops do not have time to do it this way.  I assume every thing torqued correctly.
If there is binding the triple clamps may not be aligned or the tubes could be bent.

Well, starting with the obvious are the fork tubes level at the top clamp in the triple tree? It also looks to me that the bottom clamp on the left looking at the photo is a bit lower than the right.  Notice that the yellow paint on the bolt head is missing on that side also.

Damaged in shipping, maybe but you would think there would be some other sign of damage.

Seller lying to the buyer, it happens.  There is some reason the bike has such low miles.  Was it parked for many years after it took a hit to the front end?

Like retro says losen things up, get the fender off and see where you are at.  Looks like a nice find and will be well worth the effort to get it straightened out.

Thanks to you all.
I feel that there is hope and that I will be able to ride straight soon.
