I need a lower fork leg and found this on the bay of theives.
It has an obvious crack at the top of the leg, so how important would this be as to the actual function of the forks/bearings etc. I can get it welded but would seek your advice first as I know sweet FA about these things.

never, ever use anything that has been damaged on a critical item, which the fork is. there may well be other fractures not visible which could prove fatal. keep searching!
-
+1, you have to ask yourself, why did it crack? Would you want to risk? It may be bent as well.
-
Thanks guys, you have just confirmed what I was thinking. Maybe I was getting a bit desperate! :-[
-
I have some fork legs you can have cheap - they have new seals in them too ;D
-
Think they might be later than the ones youre after looking at the ebay page.
-
Thanks for that GJ, do you know if they would be compatible with my earlier forks?
-
Will probably fit and seal OK but the brake caliper brakets and calipers are different
-
GJ, just out of curiosity what are you looking for in the gold coin department? The brakes are not a problem as some dickwad has bastardised mine hence the search for a new lower.
-
Hi Mike...£20 posted? Basically just trying to recoup what I paid for them.
Cheers
-
I would check on CSML for compatability of the internals (using their schematic diagrams) because from memory (when I was sourcing bits for my original basket case), the lower internals are different so if you're using internals from the earlier (upto early k2) they may not fit - worth a check

GJ, I might take you up on that. Do you know what year they are? I shall do some homework on that.
Phil, pardon my ignorance but what/who is CSML?

Mike
Its a Dutch 'Dave Silver' but it has all the parts schematics - Here's the link - http://www.cmsnl.com/honda-cb750k2-four-european-direct-sales_model14369/partslist/

Hi Mike, TBH I don't know :D
I bought them from Bitsa on the off-chance that I could use the fork tubes which luckily I was able to use with the standard bottoms. Only difference is that the tubes were about 7mm shorter than standard so the old girl should steer a bit quicker, not that ive noticed any difference.
Let me know if you need any more photos.
Cheers
-
I think that even if the internals vary the bottom allen screw that holds it together is the same so they should fit, you need to use the internals that go with the steel tubes to get the lengths correct
-
Good day to you sir :-)
You mean the damping rods etc?
I can send Mike them as well.
-
The damping rods and springs yes but they should stay with the relevant fork tubes due to length and end machining differences
-
My main problem here is that I have 6" over forks on my bike and I have no idea how the internals are set up.
As a little Spanish man once said......."I know nothing...K"
-
Hopfully what thay have done is just fit a 6 inch piece on top of the spring.
Main difference is very early ones had a long threaded rod up the inside that joined the top nut to the damper and if it wasn't there or unscrewed from the top nut the sliders fell off if forks lifted too high. Later ones had a reducing plug welded into the bottom of the steel tube and the damper will only come out of the top
-
GJ, could you possibly take a picture of the other side of the forks so that I can see the mudguard fixing points please. :D
-
Will do when I get home later.
Cheers
-
Here you go Mike. Looks like any dodgy threads have been helicoiled too ;D
-
Thanks GJ your a star. I will let me cuz see this and if he thinks it will work we can make a plan. It may take a few days though but I wont forget. ;D
