Bicycle that will fit "Silver Slant"

You really don't need to run that rich of an oil mix to 'break in' the motor. If you read the last couple pages of the thread tittled 'Opti 2 - 100:1 mix' (or something like that) you will get some ideas for a clean running, smoke free gas to oil mix.
I'm a long term Opti2 user and I've been breaking in and running on Opti2 with my gas bikes.

Nice build! im new to motor bicycling and am looking to build an almost identical bike to the yours. Im gonna use the same bike and frame and have been seriously considering buying off of ebay from boygofast. Im curious how fast the 49cc engine makes that bike go? also did you need the universial motor mount for that frame or not? any other suggestions about building on that bike, let me know, thanks!
