if you down shift and over-rev .. say hello to valvetrain damage.

I do seriously try to avoid it, but dang it still happens once in a while...

I was just worried about valvetrain damage. With a MN6 in first it gets to redline so fast that if your not paying close attention you will hit and sit on the rev limiter for a sec or two. I have had it pop about 4 or 5 times and it doesn't sound good to the engine but I guess it's better that going over. It's never a problem with any other gear, just first.

You will know it cuts in and out real quicky it is bouncing back up and then off 3-4 times a second.

So is that what I am hearing? The rev limiter kicking in? I was thinking the ignition was breaking down at the higher RPMs. Now this has only happened twice to me, so it's not like it's an every day thing. It just winds up so FAST in first that I'm just not ready when I should be. Just need to practice more I guess and get my ears tuned to where the shift point should be.
