The bolts on the early Zephyr 750 head have a slight penetration and will cause oil seepage and oil leaks through the threads. Oil leak prevention bolts and pre-coated bolts are special bolts coated with micro capsules, unlike liquid gaskets and liquid locking materials. When tightened, the capsule collapses to create a sealing and thread locking effect.
Heat resistance temperature of orange precoat: 150°C
If the oil is leaking from the camshaft plug Replace together with the head cover gasket and camshaft plug.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
One year has passed since we started using it. For now Oil bleed etc. etc. There is none. Oil bleeding from the under hole of Initial ModelHead which had been plagued for many years was easily stopped, so I am satisfied with Large change. It is an atmosphere that it is likely to have until you open the next Head cover.View Detail
If you thought about giving up, this kind of thing from Mr. GOOSE. So far Gasetc. Although I tried variously, the Oil bleeding from the preliminary hole which is Penetrating for some reason did not stop. I tried using Bolt here and it stopped just fine. How long is the durability after that?.View Detail
