Can the LT5 experts fill me in on..... - ZR-1 Net Registry Forums

Ok, I think I have an idea why, but am not really sure, so can the LT5 experts who have the knowledge and understanding of this engine explain the following to me....
Why is it that if you let the Z sit for a week or even two weeks before you start the engine, that there is not any chain rattle upon first start-up???
I understand why there is chain rattle during some restarts, and that there is a kit available (which I have) that once installed, eliminates that problem or almost completely eliminates the problem.

We had the Z out today, and first start-up, no noise, most restarts after that the dreaded chain rattle.....
Just trying to learn more about the system......thanks for any info........
