I have a friend that got one of this engine kits and it vibrats so bad that it radles off nuts and bolts. But, when it is running right it flys.

I loved the way this kit went together. it,s easy to build, beautiul to look at, and it runs perfectly. you include all that is needed too. this is my third kit the other two were notany way as easy to build. each from a diferent company. yours is by far the best. as soon as this one is sold i'll be ordering more. Great product and perfect instructions!!!

IT TOOK ABOUT 5 BUSINESS DAYS TO GET MY ENGINE. IT TOOK ABOUT 4 HOURS TO GET IT PUT TOGEATHER AND STARTED. I HAD TO MODIFY A FEW PARTS TO GET THEM WORKING PROPERLY AND THE INSTRUCTIONS WERENT ALL THAT DETAILED, I WAS SURPRISED AT HOW EASY IT STARTED AND WAS VERY SURPRISED AT THE POWER IT HAS!!!!! ALL IN ALL IT WASNT AS BAD TO PUT ON AS I THOUGHT IT WOULD BE. I WILL GIVE IT A 4 STAR WOULD GIVE IT A 5 IF THE INSTRUCTIONS WERE A BIT MORE DETAILED.

I just got my new motor today 6-4-10. I like how it was all packed in. I open it up started looking at all the parts and i was in shocked this is my 2 motor kit and this one is so much better built then one i got at gasbike.net.. i will not got to that site anymore. only thing bad was the intake pipe was sligtly to large for the carb. lucky i had one that was a bit smaller just had to make a new carb gasket the engine is running really good and this is the best kit i ever found it was also cheaper then the first one i bought and it was a 48cc kit give it 4 rating cause of the intake pipe issue

I ordered this product, and it took roughly 7 days to get to me.
Overall, it's not bad at all, and BikeBerry's service was right on the target.
Just so there's no mistake, this is truly a do-it-yourself kit engine. Some of the parts are 'not' well 'finished', meaning you may have to do some minor filing and so forth, to get them ready for prime time... and this engine is NOT just a 'plug and play' item.
You really have to pay attention to detail and install it right. The installation instructions are 'decent', but that said... they are NOT completely clear in places... so you have to have your thinking cap on, and THINK about what you're doing when you install this bugger.
Since I got it running, it's done well. I'm still breaking it in, so I haven't gone to full speed with it yet, per manufacturer recommendations. That said... it does NOT turn a bicycle into a moped or motorcycle... it turns it into a BICYCLE with a little helper motor on it... so SPEED is NOT my concern.
You have to watch the parts, especially the clutch handle and housing... because it's made of pot metal and IS subject to breaking easily if you put too much stress on it, trying to force it onto a powder-coated handlebar like I did.
THAT said, the engine has completely lived up to my expectations and needs. It shaves about 10 minutes off of my normal bike commute time (which was 40 minutes and it's now down to 30 minutes, depending on traffic lights/traffic). And more to the point, my legs aren't spent from pedaling uphill, since the engine does that work for me.
This do-it-yourself kit IS a winner, for what it was made for, and I'm completely satisfied.
Only suggestions for improvement I have... are to get an after-market brake lever that lets you actuate BOTH brakes by pulling the handle... (This lets you pull the clutch with your left hand and actuate ALL of your brakes with the right hand... as opposed to just pulling clutch with the left and only using your rear brake with the right hand.
Including a head/tail-light kit that WORKS with the engine would be a great thing too, since most jurisdictions require a head and tail-light at night, and some even require them all the time.
Including a chain-break tool in the kit that's made for the stock chain, would also make assembly easier.
Otherwise... it's a good kit and those suggestions I've made, are just minor ideas that came to my mind during the build process.
