I have a theory that is has to do with the pulses of the alternator and the injection pump but I really don't know. The high compression is probably also a factor.
The G60s have a record of spinning their crank gear. They have a bit more junk attached to them though.
It's going to take more than 4.2% to smooth that over.
is that REAL 'shine, or the crap you get at the booze store?
Looks like real shine to me. Those be the infamous Mason Jars
You can buy 'Shine at the liquor store now'a days, even comes in a Mason Jar..that stuff does indeed look like the genuine article tho, and not some knock-off you could legally buy :-p
