One of the things that happens when you "crack" open the throttle, is that the mixture goes a bit lean.  When the throttle is closed the fuel flow to the engine is through the pilot circuit as the engine idles, and when you crack open the throttle the fuel flow needs to come from the needle jet and pilot jet circuit....and it doesn't happen instantly.

So when you crack open the throttle too quickly - the mixture goes lean and it can cause detonation as a lean fuel mixture can "explode" rather than go through a smooth controlled burn.

So.....stop cracking open the throttle!  This is not a sport bike and should not be ridden like one!  You should add throttle at a much slower rate for this big single.  As the rpm's increase you can roll on full throttle......full throttle should not be used at low rpm's.  If you feel the engine lugging and shaking as it pulls - you need a lower gear or less throttle.

I don't jump to full throttle, it seemed only about 1/4 throttle when it happened. Definitely no where near 1/2 throttle. I don't treat it like a sport bike. My last bike was a 4cyl 600cc. I know this isn't that. I have the idle set to a smooth, "quick" idle. It does not lope. I'll take your advice justin o guy and just give it time. Also gonna check the valves at 1000 to see what they look like.

Thank you to everyone. If anyone else has advice it would be appreciated as well.

Knowledge is power.

I went and listened. I don't know for sure, but I Do know it won't hurt to jack up the idle a little. Go ahead and keep it spinning,

I'm 1/2 way (ish) between Dallas and Shreveport,, Longview area.
So far,nobody has ever seen engine or clutch problems caused by running
Shell Rotella T, it's about $13.00 ,available at Tractor Supply,Wal-Mart,
It's cheap and it's good..
As long as it's idling at 1,000 RPM or better, you won't wreck the head because the cam isn't getting enough oil.. Provided the oil you're using isn't thin and failing to maintain a film.

savskat, I'm down here in San Antonio.  If you want to meet somewhere in the middle some Sat or Sun, I could take a listen to your bike, go for a ride on some back roads, chew on some lunch, have a barley pop, what ever.  I'm out riding just about every Sat and Sun.
Let me know.  PM me,

Youz_guys has the same idea that I do.  I live in Killeen.  If you want to meet up sometime, go for a ride, talk about bikes, grab a burger or something just hit me up with a pm.  I'd love to go ride around Lake Travis, maybe hit up 2769.  There are lots of roads around Austin that I've wanted to cruise.

FWIW, your idle sounds nice.  As for your "clack:"  I've previously played around doing 30mph in 5th gear, just seeing how the engine does under that load and giving it lots of throttle.  It kinda makes that same sound if I crack WOT.  If I had to guess without seeing it in person, I'd think it's related to the initial low idle and giving it throttle faster than the engine wants it.  I'd assume that this will change over the next few hundred miles.  Just my $0.02, YMMV
