Its tough breaking in these small displacement bikes esp when the recommendation is 300 miles and keeping rpm' limited... yea good luck with that, with stock gearing they start screaming over 35mph... for me on the Storm150 i bought for my daughter to learn on, getting gas at the closest station, i need to hit atleast 50 mph in order not to get in the way of traffic.. What i recommend is look at swapping out the front sprocket after a few lessons and adjust the stock carb as they all come pretty lean from the factory. As far as oil changes ive done them at 0 miles, 10 miles and 100 miles and use Rotella T4 15w40, nice and cheap and most certainly does the job. Also, adjust the valves soon after assembly.
