x 24 TPI threads for the freewheel to mount onto it, and I see that it is not threaded to accept a freewheel so I so not know of any way to mount one to it.

VAlso the hole that was machined for the jackshaft bearings was too large for the bearing allowing the shaft and sprocket to wander and jerk around.Each BBR Tuning bicycle engine kit comes with a digital installation guide that takes you step by step through installing, adjusting, and fueling your brand new engine kit for the ride of your life.

Sorry hellboy i wasn't trying to poke fun at you sometimes i just can't help to be a smart A** I wasn't trying to insult you at all, i know how impatient you can be waiting for a new bike I'm on my 3rd bike and everytime i get a new one i try to find out as much info in advance as i can don't take it to heart i was just messin with ya a little, it will be very obvious when you get the bike like i said it's on the left side down low on the block and mine actually had a long white sticker on the top of the motor on the transmission case that had a real long number on it but the serial number was the very first part of the number on the sticker so check both places and let us know what it says also look at the number cast on the head. the problem is that a lot of the engines stamped 48 and 49cc are actually 72cc, when you remove the head you can measure the bore size and you will notice that almost every engine stamped 48cc that I have come across is actually 72cc.

If you’re looking for a tough, reliable, long-lasting bicycle engine kit look no further than our BBR Tuning 5G 4 stroke engine! this 49CC kit was a BIG SURPRISE how easy and how much power it has, I weigh 215lbs and it zips along around 22 mph (40 tooth sprocket).c. = more bottom end torque) but i can catch him once we get going and stay side by side with him at 25-28 mph. of the sellers have no idea what they are talking about and put too much jibberish out there that people listen to. If you would like I can make the kit without the sprockets and chain, and you can choose those when you pick up the kit? If you sit the piston on a flat surface and measure to the top of the wrist pin hole then that will tell if you have a high or low hole piston.
