Water pump seals, possible infection.

I'm half way through replacing the water pump seals.
I removed most of the seal paraphernalia apart from the seal embedded into the clutch cover housing that was rusted into place..
To do this I had to remove the clutch cover housing ( knocking off the gear change U spring in the process).
The replacement seals are coming from eBay via China, however due to the Corona Virus, my order, although they arrived in Spain a week ago, delivery will be apparently delayed.
I am no expert in viral diseases but mechanical seals should not pose any health threat.

As an aside I was looking at the oil distribution mods whilst I had the clutch cover off but decided against it. I usually ride at a steady 4000 RPM with the occasional increase for an overtake. The mods seem to be for riding at much higher revs.

BTW original Kawasaki oil filter costs $$, However I bought one locally for 5 Euros. Champion COF023.

No trees were harmed creating this message, however some electrons were very inconvenienced.

The 3 banjo bolt replacements or drilling of existing banjo bolts can only improve the KLR engine lubrication system. Kawasaki did this themselves for the KLX series engines back in 1993!

The KLR series engines are the only ones to EVER use the tiny holed banjo bolts. The banjo bolt by the starter motor should at least have 2 holes to properly feed the other 2 holes, shouldn't it?

With more oil feed thru the oil pipe, the 4 camshaft bearings, 5 free-spinning gears, the bushing in the clutch hub, all transmission and upper rear balancer bearings receive more oil volume.

Simple, Cheap & Easy.

Sorry to hear about your parts delay.

Is there a forum topic on the banjo bolt mod?

That does seem like a quick and inexpensive mod.
I don't have any imperial 1/8" drill bits so I'll use a 3mm drill bit.

Still no parts delivery!!!
