recomendations to do fork overhauls

Folks,
After 3 different trips and $350 to get my forks on my 82 750 Seca to stop leaking less then 200 miles since first overhaul. Dealer will not do it for free any more. This is all within 1 year. Well he doesnt take any more of my money. Can anyone recommend someon who can overhaul these and stop the leaks. I am a mechanic but not sure I want to jump into this. Please let me know.

In the FAQ Suggestions section there is a great thread about overhauling the XJ750 Seca forks (I didn't write it but I used it). The most important thing is to not DESTROY the wave washer when you are driving the oil seal out (i.e. don't slam the fork down...only slam it up - and I posted this at the end of that thread). The wave washers are not available anymore.

It's not a bad job. Mine actually are leaking again, but I think it's because the chrome is marred on the fork tubes. How are your fork tubes?

 

My chrome which shows on the tubes has a few pits which I couldnt rub out. I wouldnt mind taking it to another dealer and having it done right. that is if I could find someone who stands up to thier work. I figure I already have 3k into this rebuild. Way more then a average joe would spend. but this was my first bike and I would like to keep it around for another 20 years.

Did the anti dive system cause you any fuss? Maybe I will get everything from Len and take it to another dealer. When I dropped these off the first time it took them 3 weeks just to get the parts in. Putting togeather a list of things which I should change is the question.

 

Nope.
Graduate to "Leak Proof Seals"

"Leak Proof Seals" are the best, I had similar problems with both my XS and XJ. No leaks since I put them in. If your fork tubes are pitted you will still have leaks no matter what you do. You can live with the leak of find another set of tubes.

 

Ok...know something about chrome. Chrome is a surface coating, much like paint, which protects the metal underneath from oxidation.

Unlike aluminum, where the oxidation can be buffed off and the surface smoothed, pitting is not the chrome oxidizing, it is the chrome FAILING and the metal underneath oxidizing.

Once chrome fails, it's all damage control. You can remove the iron oxide that wells up from the pits, and you can fill the pits with wax (chrome polish) to keep moisture out, but you cannot restore the surface without RE-chroming it. Those pits have sharp edges which will dig into the seals every time the seals pass over, damaging them and allowing oil to leak. You could always try to get another set of forks (I got a used set for$30), take your chances on getting better tubes, and lots of spare parts.

WHOOPS...it's not in FAQ Suggestions, it's in XJ chat - Chorca is the author: http://xjbikes.com/Forums/viewtopic/t=1 ... seals.html

The thread covers everything, including the anti-dive units on the forks. Really nothing to it, only REAL gotcha is the oil control valve wave washer. Also, it REALLY helps to have a helper for some of the more dexterous tasks...like removing e-clips

 

RickCoMatic,
It looks like they only can be bought from England, Do you have any suggestions on what internal parts I should also change or just try these first.

Thanks

 

If you have pits in the fork tubes you might as well replace them. Otherwise they'll keep ruining new seals. (Whoever serviced them should have pointed that out first time!)

Chacal can hook you up.
