I bought my current engine in late 2009, had it on another bike I had for sale. Well, That's about the time the economy tanked so it never got sold and I just rode it around for a while. It was an OCC chopper build and just too hard of a ride for me. So I got a 2011 Cranbrook and slapped everything on that. It starts with 2 kicks of the pedals when cold, 1/2 kick when warmed up.
and unless your 49CC bike can do close to 40mph I don't think you could touch me. I ride at least 35mph everywhere I go. My average ride is a 20 or 30 mile round trip. Heck, My girlfriends place is 14 miles from my house.
But I KNOW yer right about one thing, The oil mix is the key, go just a little on the heavy side on it. Your entire engine depends on getting the lubrication it needs from the mix. 2 oz. of synthetic may be great for a clean burning, fast running top end. But I don't see how that could be enough to get enough oil to those chinese bearings. I figure they need all the help they can get. So I use REAL oil, (the cheap stuff,) and run it a little heavy. I don't really keep track, but I know I have well over 2000 miles on it, no problems.
