I always run 30% in my Saitos and YSs. I even run it for break in. You will be fine. Just run it a bit rich at first. The Saitos need to be leaned down quite a bit on the low end. Even during early running.

You'll be fine to run the 30%. Any you won't believe how much better your engine will run. Not only more power but better transition and idle too.

Thanks
