I am listing this for a guy I have been teaching that is going all electric.

When I bought one of these he had to have one too.
After 3 gallons a piece of the wrist pin keeper broke off and went into the piston.

It was just bad enough to have to replace the piston and ring.
YS warrantied the parts and I did the work since I am sponsored by them.

New piston, ring, wrist pin keepers, rear bearing.
After I rebuilt it I put it in one of my helis and ran a gallon in a half thru it to break it in.

It runs like new and has great compression.
We are running 15% Power Master.
The pipe looks like new.

He wants 425.00 for the set or 175.00 for the pipe and 275.00 for the motor.This is a smokin deal for somone that wants to get into a 120.

I rebuilt this and broke it in so I can vouch for this motor to run like it did from the factory.

I must have 40 gallons thru mine with no issues.

He removed the top fin on the block. dont ask me why.
It is under the head so it can not even be seen and does not affect the performace in any way.The seal is on the head gasket liner and the head.At this altitude and the right tuning it almost makes the power of an E

Also if you are planning to put it in a Align 700 then he said he will include the moded fuel tank to run with the ballon and suringe for removing the air for free.

This is a must for this motor it will not tolerate air bubbles.
With this mod it runs very consistant

I'll ship priority mail with ins. and delivery conf.

Check my feedback and buy with confidence
I will ship to USA only
I take PP only
