I’ve not long had my bike and having thought I’d sorted most of the issues to make it useable I seem to have an oil leak either from the tank or oil feed pipe, I’ve had both out and looked at them but can’t find anything obvious. Is there anywhere on either of these that is common to leak that I should inspect more closely and are new lines available anywhere as Fowler’s website says they are no longer available. I don’t fancy using it with oil leaking onto the swingarm in front of the back wheel. Thanks in advance.

What is most common is people over fill their bikes, should be checked right after a ride (engine hot) with the bike upright (not on its side stand) it is not common for the oil lines to leak.

Give it a good de-grease & pressure wash & keep an eye on where its coming from, it could be a pin prick hole in the tank?

Mezo.

Without a picture difficult to say - but if not what Mezo has said then I would just drop the oil, remove connections, for those with o rings fit knew, and those face to face make sure very clean. I have had leaks from old orings and for the bottom engine one from excess paint which was affecting the small oring from sealing. The orings should be exact not a similar size! Look forward to a picture......good luck

Just a tip, check a small 10mm head screw under the starter towards the stator cover , that fixed my leaking nightmare. was'nt any line or hose, but that screw that was no there

May be damper oil from the rear suspension, if the boot is oily on the inside
