i am lookin into bore my fiddy lightly to lik a 75 or somthin and keepin the stock carb just jettin it and throwin a cam in it but i cant find a kit ilek this i want a cheap up like 200 bucks maybe

 

check the sik50s.com site, sanomx.com, fast50s.com and classichonda.com. not sure about pricing but they're out there, $200 sounds about right. 75cc/cam and stock carb/intake are very good choices for a stunter fiddy too.

I'd say go with a 88 light bore It comes with a cam keep every thing stock

I feal its makes great stunting power so much torque it's funny

 

get one from fab5

 

i think jemar paid 200 for his 75

 

i can hook u up on the 88 light for sure. however, if yer set on the 72cc go to dratv.com and purchase the piston and gaskets. then go and find yourself a good used old 70 cylinder. they are a dime a dozen. there's your 72 kit for under $100 easily.

 

the 88 kit fab sells is worth the 275...definitely...

 

Basically somthing like this right? http://dratv.com/xr50to70coki.html

PM me a good place to get just the 70 cylinder?

 

thats it. look on ebay for the 70 cylinder they usually go for around $10

 

wouldn't you have to rehone an old cylinder?

 

it would be a good idea, but im talkin about a low buck job here. it will run. it may smoke if its really hagged.

 

i jus orderd my 75cc light bore kit with cam and all gaskets piston rings bearings and all for 213$ to my front door cant wait for it to com in o ya og it from www.sik50s.com

 

I think im going to do this cause Im cheap, should I use the cam for a 70 also?

 

the cam must be a roller bearing type if used in your 50 head. if u cant locate one i got what u need.

 

I got one I will give away. Pay for shipping and it's yours. It is kind of nasty though.

 

Weedracer, what set up are you running? Whats your thoughts on an 88cc kit with stock cam, carb and exhaust?

I got this one (well before I knew mr fab5 delt)

I got it with the sic50 custom cam
and I can't stress enough keep every thing stock if your going to stunt, the carb air box and pipe (that means the guts to the pipe to keep everything) and sprokets

you ask why

well if you open every thing up like add an air filter or a pipe yes you will gain very little top end a little more if you put a bigger carb but makes it hader to stunt the power is just to broad(sp) spread out ( does that make since)(my mind is mush today sorry)
but by keeping it stock the power is so easy to ride and snappy the torque is crazy you can creep so slow it 1st gear wheelies, you don't have to pull up at all unless you pull it up in 3rd just a slight tug and its up

me and my buddies have tried so many set ups and that is by far the most funest stunt set up

 

so for the 72 kit i found a cylinder head with it too, should i get this too or will my stock head work fine, p.s also will my pipe bolt up to the new cylinder head too? thanks

 

If you get the 47mm piston from dratv.com, they have one that is made for the 50 head. They also lowered the price on it to $39 from $54. Then just get gasket set and your ready. Im not trying to plug them, they have just always been pros when it comes to getting parts to me.

The XR70 stock head needs a dome shaped piston, where as the 50 is flat. So DONT put a standard xr70 piston on your stock 50 head or bad things will happen.
