about to change my break in oil now at 5 hours, what all do I need to grease at this point too? thanks

pull the drain screw and pump old grease out and put new grease in. I'd grease the zerks on the pivoting shaft a little bit too. Change the clutch oil if you feel you need to as well, although you probably don't, its cheap and easy. I run my motor really hard so I try to do oil, clutch, and shaft grease every 10 now and new spark plugs once a season if the carb is running right. I'm pretty new to these gtr's as well though so maybe a more experienced voice can help more

You don't have to change it that early you can go at least 10-15 hours before you change the oil, but all people are different, the shaft grease you don't have to do right now until about 15 hours and then you can back the shaft screw out(if you don't and you pump grease in the zerk then you'll blow the seal) and put grease in your shaft till you get a steady stream of grease flowing out of the shaft. The clutch oil is the same as the oil that you run in your motor, not gonna hurt anything, But i suggest going back with Rotella or Mobile 1 or go back with Amsoil, its up to you
