[QUOTE="Peter Holmes, post: 154197, member: 302"] The oil leakage from the oil filler cap on my D Comet drove me crazy, I tried all the things you have tried, and nothing was 100% successful, at its worst it was bloody dangerous, covering the RHS of the rear tyre liberally with oil, the problem always manifested itself at its worst if I had been engaged in what we might describe as spirited riding, lots of revs, in the end I have managed to cure it once and for all, I did have to sacrifice a FT130 to achieve the remedy, I don't own a lathe, but managed without one, hacksaw the threaded projection off the FT130 to leave you a thick flat disc, reduce the diameter of the disc to exactly fit inside neck of the oil tank, drill a hole through the disc to correspond with the chain oiler adjuster screw, countersink a little the threaded centre just to clear the filler cap, although that might not be necessary as it will sit quite low in the oil tank neck, then to the side drill and tap a 4mm thread, this is to enable removal of the disc when required, I leave a 4mm x 20mm socket cap head screw loose on top of the disc, always there when needed, and it can't go anywhere. A very low tech, Heath Robinson solution, but it has completely solved the problem for me, I can now rev the nuts off it, especially when chasing my Son on his NSR 250 (no chance whatsoever) but when I check the top of the oil tank it is as dry as a bone, and removal for checking oil level and topping up is achieved in a thrice, and without the need for any tools.
