I would like to know if the e-ton 70cc kit will fit on a e-ton 90cc?
do the e-ton 50,70,and 90's use the same block just differant heads and crank?
I'm looking at the 70 kit cause I heard it was alot faster than the stock 90

 

??

 

have you tried to contact a rep that sells the eton? My son riders the viper 90r and I cannot imagine that the 70cc would be faster?

 

I went to 2 races and the 70 ate the 90 for lunch and both the kids were good riders.I'm just asking I really don't know. I'm new to the whole mini atv thing

 

I would imagine that the whole shot is due to the gearing and not the horse power. The right combination between the different sprokets would make a difference if you ask me.

 

I never said anything about a whole shot.Thanks for the reply

 

Whole shot might have been the wrong choice of word, but if the 70cc were beating the 90cc it might not have anything to do with the the amount of ponies the egines produce but rather the set up. You do not have to have the strongest engine to win an race but rahter the right cobmination ex. tires, gear selection, carb adjustment that works best for that track.

 

It has everything to do with the 70cc bikes being much higher hp motors than the 90s. Most of the 70cc kits have fairly good porting and the 90s have low flowing low duration #'s. A 90 built the same will outrun the 70s fine. There are many other variables and a few 50cc/70 kitted bikes I've done run extremely well and will outrun 99% of the 90s. Same with any good builders ported 50 or 70 kits.
