How Much Pre-Mix
I have 2005 GP1300R that is currently being rebuilt. I wanted to know if its a good idea to add a pre-mix even if I use the oil injection. If so, what would be the ratio?

I was thinking of switching to premix, dont want the oil pump to fail on me.. but definitly choose one or the other, either way works just fine

I have always heard after a rebuild or new motor run oil in gas as well as oil pump for the first few tanks

As far as pre-mix vs. oil pump use, CJ gpr you just opened a can-of-worms . I'm not going to get into the point/counterpoint that could develop now

For break in pre mix first tank 50:1 with oil injection per owners manual. Page 3-13
Link to owners manual.
If you are not running oil injection mix the first tank 32:1.

I look at it this way. I'm going to redo my top end at 100 hours no matter what regardless of the compression. On the other hand I'm going to I want to get the most out of this crank. So I came to the conclusion that I will mix 32:1 regardless to keep my crank bearings happy for the long run.
If you could find the article you mentioned I would like to read it. Not trying to sound like a d!ck, but it sounds like an interesting read and I would like to see the difference in break in's. I have never seen anyone post concrete compression numbers saying said break in was better then the next. I wouldn't really expect it be accurate either as every motor is different.
