05 400ex oil leak near manifold

[Snyder]

i just recently got an 05 400ex. it has quite a bit done to as far as i can tell. i know for sure it has a LRD pipe and header. it also has a cam. i imagine it has quite a few other modifications done to it because it will out run my friends yfz 450 at top end. anyway, it leak oil near he manifold when it gets really hot. it will drip all over the manifold and smoke. heres a pic to better illustrate where it leaks. the blue circles parts are where it leaks.

it uses some oil, but not alot.
any ideas on how i could fix it?

You will have to remove the top cover and re-seal. Use 3 Bond. Yamaha Bond or similiar. It's a grey sealant and never had a leak again after using it. Just a thin film is all that's required. Don't overdo it.
