I know there are several different variants from Fast50's.. one is the one that comes with a cam and everything.. Anyone know how this thing runs compared to the basic 88cc big bore?

thats the one

 

As long as the motor is going to be apart spend the extra couple of dollars and get the 88cc kit. Seems like a waste otherwise.

 

Fast 50's motor kits are so overpriced its redicluous. Contact Fab5Fiddy and get a complete 88cc kit from him with cam, 20mm carb and everything for like $275. Its a dragon racing kit just like I have in my Fiddy and I couldn't be happier.

 

Well, from what I hear the 72cc kit from Fast50's with the cam will hang with any standard 88cc kit.

I'm just asking cuz I can get that kit for $100 instead of the regular price of $399

 

For $100...buy it RIGHT NOW...Thats a great deal !!! .. $399 definately is not.

Keep in mind that that is a high compression kit and YOU MUST use race gas with it. If not you will wreck your motor in no time........

I still think you might be better off with a standard 88cc kit with everything for $275 and you will have lots more torque......For Stunting and general riding you don't need such a high compression ratio. I think that Fast 50's kit, is just made more for top end power.

 

how does it compare to the 88

 

see above.....that Fast 50's kit is a track only kit.......... Not really a daily use kit.


I find it hard to believe you can get that kit for $100

 

i dont wanna run race gas, but from what I hear almost all the big bores say to

 

Thats not true.......

That is a wild looking piston..... I bet it is a 13:1 or more compression ratio.

A lot of those 70cc kits have to be used with a 70cc head because of the dome shaped pistons most kits have.

I would still buy a 88cc kit......

Remember

There is no replacement for displacement

 

You dont have to run race gas with it, you need to run high octane, like pump 93. You run race gas with massive ported and super hot cams and such with it. And Mx racing 4 stroke gas is only 94 octane anyway. And i heard the 72 kit does hang, and maybe faster, than most 88 kits. It doesnt have as much botem end as the 88.

 

Yo does fab5 sell his kits on ebay I been wanting to buy the 88cc on ebay but the guy only take paypal my wife fooked up my account and does not remember the password and im to lazy to fax them verification and I dont have a fax machine anyways. I been looking all week for a good kit and only want to send about 300

 

dood, u dont live far. ill meet u somewhere and u can give me cash or whatever. hit me on a pm if u want.

 

I dont even want a big bore.. I'd rather have stock.. just knew i could get it cheap

 

just go get a 70 motor and be done with it
anymotorcycle junkyard will have one ,but probably not for a hundred bux
anything over 10:1 needs race gas or hes right itll ping itself apart

 

thats funny my big bore kits are 11:1 and run on 87 all day long

 

yeah these fiddys will run strong on whatever you put in the tank! sometimes i get cheap and just use sugar water...
B

 

Heheheheh
Not For Long

 

running any motor with over 9.5:1 compression ratio on 87 octane is asking for trouble. maybe not today but it will happen eventually.

 

these bikes dont have enough ignition timing to do damage. i havent heard a single ping out of any of the 88 kits ive put together.

 

nags...are you going to buy that kit? or you want to pass it on to me?
