No, just have your sponsor order you a whole 2 Kitaco 117SEs. Than your mechanic can rig up a set up so you have 2WD on your fiddy.



Mad sik...

Oh I am just as serious as everyone takes you as. Im not sure if your brain understood that but what it meant was no one takes you serious.



and IF you were serious about all of this, why would you use a LIFAN crank?

If your to the point your making your own bore kit you should be able to figure out if it will fit. Order some gaskits and try it. If it doesn't fit all you did was waste one day.

Billy,



A 51mm crank and 52mm bore will make a 108.



A 51mm crank and 51mm bore will make a 106.



Use the correct terminology and people will be more able to help you. A 51mm stroker crank is standard to Kitaco, a 52mm stroker crank is standard to Takegawa. It makes a huge difference which one you have, as you have to match the correct piston.



For example, if you run a Kitaco Ultrahead 88cc motor, and want to make it into a 108 Ultrahead motor, you have to change out the crank and the piston, as if you use the 88cc Ultrahead piston, the motor will have way too much compression and it will lead to quick failure.



I highly recommend you do some extensive research on motor conbinations before you start posting any more engine questions, as the information you provide makes little sense.
