Note: never, EVER mix a low ratio pre mix oil at high ratios to overcome an oil spitting issue.
You will rob the engine's internals of proper lubrication and the engine will get ruined quickly.
i had the same issue during the break in period, once i started to ride the bike more often and use the 1-25 ratio i had less problems, make no mistake though it will continue to happen unless you purchase a high syn oil which is much more pricy
