Oil Channel Bypass Lines for Head KZ650/750

Regular grade gasoline is just fine, and paying more for higher octane is a waste of money.

Where the engine has been modified to have higher compression ratio, higher octane gasoline may be required to reduce or avoid pinging under acceleration loading.

Good Fortune!

Seems that it would be relatively easy to reproduce a reasonable facsimile.
Short length of aluminum bar stock drilled for a longer cross bolt, with tapped hole for threaded stud in the other end.

But not as easy as the eye bolts. :laugh:

When making up an external feed for the 650/750 you need to include the oil restrictors somewhere in the system to retain the correct oil pressure.
Remember that the restrictor jet on each side of the barrel feeds one half of BOTH the inlet and exhaust cams.
Due to the small bore of this item you should be able to use braided brake line and banjo's for the pipe work which would make for a fairly cheap job.
For ease of fitment you could make up a simple alloy splitter block that sandwiches between the return side of the oil cooler and engine then bring the feed pipes off that.
By using a double banjo bolt for each sides pair of pipes you could then make each banjo bolt the restrictor by ensuring that the holes in them match the diameter of the original restrictor blocks.
Remember to block off (dry block) the now redundant original oil passages.
Filling the oil holes in the original restrictor jets with lead solder etc would be a quick reversible solution.
