If a mini is considered an iron pony, and an pony is relatively half the size of a horse. Does that mean it only has .5 Horsepower?
you can also get the pull start adapter from the DR
tbolt has a 88cc kit for the 70. Comes with evrything you need. They also sell a stroker seperatly to make it 108cc. I have heard the 88 kit from them is very nice.
with the correct piston you can use a stroker crank for a crf50 and swap in a modern cdi setup. my avatar bike is an atc70 motor punched out and stroked to 117 with a cdi crank
Just add a second lever and run the clutch cable to that, I moved the brake to the throttle side an put the clutch on the left.
Do you plan on using the stock thumb throttle?
You should order the engine from a forum sponsor like Wholesale Cycle.....that way you will have someone to talk to if you get in a jam
Seems an electric start would make things tonnes easier. I've seen both over and under mount starters on the 125 engines; however over mount requires rev'd intake mount a la KLX110. Don't think there's room under the tank for that; actually if I recall real estate under the tank is REALLY hard to come by on ATC70.
Yes, very true, I had to dent the underside to fit a vm24
I used a shortened stock Z50 kicker on my 125 ATC70 when I had it. tmas is right- a small foot helps... I have a size 10.5 shoe and if the plastics were trimmed correctly you can do it.
Also, I had a manual clutch and it was WAAAAY more fun for snow, dirt and mud. It was easy to dump and break the rear end out. Typing this makes me miss that little guy...
