<div dir="ltr">Yes, poor quality after-market parts can cause considerable grief. I changed out my gearbox sprocket on a 1972 BSA B50SS to what was supposed to be a high-quality after-market sprocket. The bike leaked gear lube from the day I installed it.<div><br></div><div>I thought it was the seal or something else and and I tried numerous fixes until I just took it back out again and put a mic on it to find that the seal surface was so far out of round that it was not even being "shined" by the seal all the way around.</div><div><br></div><div>Bit the bullet, found a high quality British-made sprocket for about 2X the price of the first one, installed it and it has not leaked a drop since then. I spent the better part of several days redoing a job that would not have been necessary at all if I had a high-quality replacement part in the first place.</div><div><br></div><div>Bottom line is that there is a lot of junk being sold out there. The money saved by "rolling the dice" on this junk simply is not worth it for me anymore. Additionally, if we do not pay the price for the high-quality OEM-grade parts, they probably will cease to be produced and all we will have left if the after-market junk that is causing us all a great deal of grief.</div><div><br></div><div>I will not buy eBay junk anymore.</div><div><br></div><div>best,</div><div><br></div><div>doug</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 16, 2019 at 5:52 AM Doug Braun via Shop-talk <<a href="mailto:shop-talk@autox.team.net">shop-talk@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>I agree, this certainly sounds like a problem with the reservoir shutoff valve not closing properly.</div><div>If it were a problem with the main seals, a lot of fluif would have leaked out.</div><div><br></div><div>I had the same problem develop in my Spitfire brake master cylinder.
