i was just curious why all you guys run a stk fiddy motor then add to it when you can start with a 70 motor and do twice the stuff with it
and its alot more durable
first thing i did was yank the stock motor
and put the 4 speed 70 motor in they arent that hard to find
yall spend all this money when a 70 motor will do the same thing
for half the price
just askin

 

it's all about heart and soul. it obviously ain't a fiddy if it started life as a 70...
B

 

it aint a 50 if its got an 88 kit either

 

Old guys with bootleg Z50's just don't understand.

 

I'll take a 70 motor for half the price!!Ya know where to get one?

 

i d go to swap meets and bike junk yards
thats how i got mine
get in good with someone who werks at a honda dealership too
trade ins are always agood source
hehehehehe us older guys
thats always been the way to do it

 

The junk yards around here are picked claen or they know what they have it sucks!!!

 

I think most people start with the 50 motor just because it is what came with the bike. It is more economical to make baby steps as well. A series of nickel and dime parts seem cheeper than a whole new motor.

 

yeah jonny i hear ya since the fiddy boom has taken off they really getting scarce the one i got was a complete xl 70 that had a rusted out tank and the guy couldnt get anyone to fix the tank and a new one was more than he thought the bike was worth from honda so he took a couple hundred bux and walked away
the other one i swapped in a group with a couple of old z's
ill keep my eye out for ya if i find one ill let ya know

 

Dont pay attention to my profile it was a joke.I am really from nor-cal.I am friends with Craig Mason the owner of fast-50s.About lets see I guess it was 99 we went on a mission and raided all the bone yards, they were almost giving us the stuff.We raided ct's sl's Z's atc 70s anything that looked like it might work.Now there all onto it and its hard to get a good deal anywhere around here.We did have lots of fun mixing and matching cylinders pistons heads just to see what would work.The 1st real kit I bought was from powroll a 72cc cylinder and cam,piston and gaskets it was 499!!!!I told them i was going to get a 70 carb and they were like hmmmm good idea lol.So i got a xr 70 intake and had to make a few different cuts to get it to work but it ran great in the end.That bike 2000 xr 50 with pegs, shifter,clamps,bars,pegs,gripper seat,tires,72cc turned all kinds of heads now its just another 50.Sold it 2 years ago and gave it away for 1000 nobody wanted it!! how times have changed

 

yeah you guys are bad
we kinda did the same around here
im still running the powroll 100 kit in an 72 xl70
got a couple of those motors
still screamin
i let some fiddy guys ride it
they acted like theyd never seen a clutch on a fiddy
put a atc 90 intake on it with a xr100 carb
its a stump puller

 

Powroll was the first to offer a complete kit that i know of

 

i had a 90cc ko back in 71 that i dirttracked been using em every since

 

71'.......MAn I I thought I was old I wasn't even an itch in my old mans pants yet!!!

 

Is there a weight difference between the 50 and 70 motor?

~nick

 

not sure to be honest
never weighed either one
i would think if there was it
would be minimal

 

I just bought a almost new 2003 xr50 motor for $350, is that a decent deal? Its pretty darn clean, cause its basically new. Also came w/ some extra random parts.

Nick

 

did it come with carb and all?

 

when I bought my fitty. I bought it to wheelie, because I meet Rodger & the control colition boyz at the 1096 stuntshow last summer.... after seeing the rocking the 50's I had to have one..... 5 months later I am totaly rebuilding my fiddy, with MX suspension and a 88cc big bore and 70cc head,
because now" we stunt em, jump em, race em and dump em!" Want to stay competitive with the local boyz.
summer 2004 MFM will MX, Stunt, & Supermotord our 50's for prizes, t- shirts, hats, patches, etc.....
I have to compete with NiNer and his 110cc stroker....

 

88 wont run with a stroker motor
unless hes a chitty rider and your like a pro
im just going by displacement
i dont know either one of your setups
i run a stroker motor and i pass 88's like they are backing up
