February 21, 201412 yr Hi all, I have a 199B spitting fork oil out of the vent holes in the caps. I am used to a little around the holes but these are spitting oil onto the tank and engine etc. - Any ideas how to fix this? - How do the caps come apart to clean the vent valve? Thanks! Keep your feet up!
February 21, 201412 yr hello ive never known this to happen may be theres to much oil in the forks. should only be 180ml in each fork. to clean the fork caps take them off there should be a tiny nut on the bottom undo it be carfull theres a small spring and ball bearing inside soak them in some wd 40 then dry spoke the vent hole with some thin wire then put them together. but my gess is theres to much oil in the forks.
February 21, 201412 yr Author Thanks for the reply! I changed the fork seals and put 180ml of 10w in each fork leg. I will drain and recheck. I too have never seen this before. I took the nut off the fork cap and the spring and flat disc. I can't see any ball bearing. I have swapped the caps with my other 199B so will test ride and see. Thanks again.
February 22, 201412 yr Mine used to spit oil out - it was the balls in the caps. Maybe you can find them because they are siezed in? You can get new ones if needed, about £30-40 from memory..

Thanks again. hi, happy to be corrected by those in the know but i believe if you have the washer and a spring then you have the earlier type, the ball and spring type have the countersunk screw in the top. the washer and spring type flap valve arrangement were fitted to the earlier bikes. however i would guess the problem is the same though regardless of type, it is probably too much oil i hope this helps
February 22, 201412 yr hi these are 1 off my 199bs forks ive just serviced with new seals and springs and new damper parts caps are the closed typ with just the breather hole wich work well.
February 22, 201412 yr Hencam is right - its a thin washer - there are four galleries behind from memory.. Nice forks Bondy, you much be good a polishing!
February 22, 201412 yr hello smelling thanks for the comment but cant take the praise i had them polished for me. i did polish another pair of forks witch look ok but not as good as the onces above.
February 23, 201412 yr hello smelling the polishing cost me £75 by pitted fork in Luton. i had both yokes powder coated £120 this was for polished sliders and powder coating and door to door carriage. i had the forks hard chromed to. Edited February 23, 201412 yr by bondy
February 23, 201412 yr Author Very nice Bondy! Should look great when it's back together! Don't think the washer and spring are old style fork caps. I have 3 B's and all are the same?? Either way new caps fixed the problem. Thanks everyone! Keep your feet up!
