just wondering if anyone knows the HP rating on these little rascals and if they are worth the money over the lifan 125?

YES!!!!!! there is no comparison to a 125,,,,, these things RIP!!! I LOVE MINE

Between me and boys we are running 4 of them
They are awesome.
And there 3 times the motor.
I started running them after my kids screwed up second gear on 2 lifan 120 motors.

OH my gawd I wanted to get one of these motors!!

They are AWESOME!!!! .....also the 150 Piranah estart....that baby rips too and has the magic push button!

You can get them with race heads and cams for a HP rating of about 18-20hp. I have the 150 elec. and it kick the smack out of my 125. the head and cams double the HP of what I have. I couldn't even image double the HP from my bike in a A+.

How does the Piranaha 150 estart compare to a TB117 with race head kit? Just wondering if it would be worth it. Ireally like the auto clutch too, so thats one of my reasons for holding back.

thanks for the input. were can I get them with the race heads? or do you just buy the head seperate from the motor and build it your self? Anybody know where the best deals on these motor kits usually are? T-bolt usa maybe? thanks..

tbolt is great I have bought stuff from them and very helpful. I bought my E150 from http://stores.wholesale-cycle.com/-strse-C.../Categories.bok. real nice guys and very helpful as well. They will do the race head and cams there and fully install. only an extra $350 and doubles the power they said. I really don't think I would want double the power of my 150. OK maybe just alittle. get the oil cooler off ebay for $16 and run it. under $1000 for EVERYTHING for sure. good luck and post pics.

I was told that we need to stretch the frame for this motor not to rub the front tire? thought Id ask before I order a motor. thanks.

I have a 150 in a non-stretched 70, as long as the tire isnt overinflated it just fits. You'll need to cut or remove the front fender though.
