arnt all these 70cc bicycle motors the same

I can't help but wonder if all of these kits come from the same factory anyways.
The joke is on us, I think!
I think that the bottom line is that if you get a couple of months out of any kit, you will have had more than your share of fun. Many go out to a bar and spend the money we spend on these kits in one night out. Honestly, what's a couple of hundred bucks when you compare other forms of fun and transportation. A bus ride is almost three bucks one way in Toronto for god sakes.

These engines are not the same. Not even close. There are at least 50 different factories and each factory has their own version. The stroke is different, The bore is different, Porting is different, Connection rods are different, Cranks are different, Pistons are different, Exhaust pipes are different, Carbs are different. some use 6mm cylinder studs, others use 8mm, Counter shaft sprockets are different. Some have larger cooling fins, and more. Now..With that said... Here is what items I have found that are similar and can work with most of the other engines. Side covers, Magnetos, CDI's, Spark Plugs, Carbs. If you buy a 70cc ring set from me and think it is going to fit a 70cc from another factory, think again. Also..There is no such thing as an 80cc 2 stroke Kit from China. It does not exist. Period.. If someone is selling an 80cc engine kit 2 stroke bicycle kit made in China, they are lying and misreprsenting their product. If you have any other questions on this. Feel free to contact me or email me. Thanks..Enjoy the ride..

Wow, that blows my mind! Imagine how many kits are pumped out every day if each factory were to put out just 50 kits per day..(50x50=2500) 2500x365=912,500.
That is very useful info, about parts interchangeability. That can be very scary.
Now I know why some clutches have round pucks and I don't.
"thanksdax"

I can only comment and say I have bought three from that'sdax and they are really worth the price. I don't know if you could make one good enough to charge much over 200 dollars U.S. shipped.

Parts between different engines aren't always compatable.

dax engines all have the roller upper too.

There are no sellers who "help to keep this place going", it stands on it's own. Unless you are talking about paying for advertising....but that's not really"helping to keep this place going".

Don't take it the wrong way. i guess it's more of a hangup I have than anything. Not wanting to recommend a brand, knowing that an advertiser will be reading my post. Sort of like being on "a Ford site" and recommending a "chrysler" and knowing that Mr. Ford will be reading it.
I hope that cleared that up.

Yes. I only recommend the that'sdax engines because I have bought three. I don't "disrecommend" any others.

Now, If I bought a kit from someone and it sucked, I would surely say so.
I just go with what I know.

great, so thats what i was asking. i have no issue spending money on an engine that others have had good luck with. Doesnt mean that i believe engine a is different than engine b, just means i am willing to spend more on engine a because of its high feedback. i think il go with the dax kit, its pretty cheap.

I've bought engines from kings motor bikes, boygofast, & powerking.
Boygofast & powerking both sell PK-80's.
Of the engines I have tried, I like the PK-80 the best.
I have no knowlege of how anyone elses engines perform.
