Hi when I got my TTR, it had a slight weep of oil from the front sprocket area...
My local bike parts shop sold me a seal but I was never really impressed with it so
after a quick email to Brian a genuine yam seal was delivered next day..Brilliant service Thankyou MR & MRS TTR
Today I stripped the sprocket off and delved around inside..
I found two seals pretty much worn out..so completely removed all traces of old seal and not knowing what I was looking at...
I phoned Brian for some great advice who confirmed everything was as should be so I followed Brian's instructions and refitted the original seal and then the second seal backwards as it were...refitted sprocket and new locktab..After a short test ride... No More Leak.. yippee!
