Oil change blues

Hey guys. I changed my oil a few nights ago with castrol 10 40 4t semi synthetic. I never pulled the oil screen thing out cause i didnt know it was there, the engine did not like the 10 40 so ive decided to try 20 50 v twin to see if it would quite the engine down and keep things lubricated well... Ive decided to remove the oil filter screen.. And i have come across a small problem the evious owner completely stripped the head of that bolt... Does any one know where i can find an extra one?

You can go to the Kawasaki main site, then head to the support pages. There you can enter the year and model of your bike and get full diagrams with part numbers. The oil filter cap part number appears to be 11012-1483. Found a few on eBay just looking for that number.

Let me just go back to the very beginning, as this makes no sense to me unless you live in -20 degree Artic weather or a 120 degree Arabian desert.

The engine did not like 10w40? It was designed for it.

You probably confused ACCT noise with .. some weird notion that the oil caused a noise. Don't waste money on "vtwin" oil and crap like that. This is an 80s bike designed for bog standard 10w40 dino oil. 10w40 synth is even better. You won't fix anything by playing with nonstandard weights and specialty oils. (The Rotella line of oils is good, though weights vary a little bit like 15w40 for the dino oil or 5w40 for the synth, they're still a-ok in my book.)

If your engine is clacky, service the ACCTs. Also the petcock has been known to echo through the tank (tap tap tap tap) as it opens with vacuum. VN750s are loud sewing machine motors anyways.

thank you for that info. I should have mentioned i changed the oil a few days ago. And upon start up with the old oil it made no clacking noise.. The noise does not continue much with the 10 40 bee oil i put but it concerned me.. Its an old bike and new clacking noise may have caused me to over think. Ill do my self the favor and just put the 10w40 back in. Ill look into the acct's and see.. Ive read that it was a pretty popular thing to put manual tensioners on there..
