I've been running full synthetic Mobil 1 10w40 in my 13 R1 since 600 miles, I'm @ 7k now doing changes every 1000 miles (Oil and filter). I was talking with my friend who has a newer R6 and USED to use Mobil 1 until he noticed some issues of which sounded all too familiar... cold take off slippage, and when very cold (for California) difficult start up (couple tries, almost sounds like a dead battery initially). Has anyone else had these issues? He recommended V300 10w40 from Motul, anyone have any input on that or any other alternatives?

I used Mobil 4t for a while in my r1 without issues. The important question is do you have exhaust? Air filter? If so have you added a fuel controller to make sure your A/F ratio is right? Is it the stock battery? I don't think the oil would cause you to have hard starting as much as maybe time for some maintenance. It doesn't have 40,000k spark plugs in it lol.

I switched to amsoil and never looked back. I like it, I can get it for under 9$ a quart, and it works great at the track. Never had clutch slippage and starts right up unless it's really cold (rare(")

To the OP: As long as your Mobil1 is 4T motorcycle oil, your clutch issues are not due to oil. More likely just the normal 09+ shitty-clutch-problem that is adequately covered elsewhere on the forum.
I use 300V 10w-40, change at 3-7k miles. 1k mile oil changes is overkill, but won't hurt anything except your wallet.
Cold starting issues can be viscosity related, 10w-40 should be fine. The real issue is the starter motor is weak, and the battery is too small to allow multiple cranks.
I keep the battery on a 900mA tender overnight in order to get a single crank fire-up down to 32*F, in the morning. I don't ride when it's colder.
