Yes, exactly!!! We would build up our MX bikes and run them stand still for 10-15 mins while reving gently just to make sure it didn't sound like a box full of rocks. 3.5 ounces to the gallon for the first tank. After the first 10-15 minutes at stand still we would take off and wing the crap out of them.

3 ounces of oil to the gallon there-after...never had a problem!

I didn't have any problems breaking in the motor on our shop bike. I went heavy on the oil 16:1 as recommended for the first tank and then changed the plug and went to a high grade of synthetic at 20:1. It works great!


BTW: My all time favorite road bikes were the RD series from Yamaha. They were light, handled well, and had a great power-to-weight ratio.
