When I ordered the twin I asked (coz the twin page said you can upgrade the carbs) Sean said "oh they come with 1107"
But when I got the motor it had 929??‍♂️.
I mailed him and complained? . Sean sent me a pair with the new crank????
They sent the 1107s for free?

Cool. That's good customer service. Glad it looks like your all sorted now??
 
It seems like the rc GODS ??? are testing my grit every step of the way?
Check this out?
In the pic are the original crank (rmck)
And the one that was sent straight from Korea ? now here is the the thing??
The small end of the con rod is not the same size ? 20200523_083150.jpg20200523_083232.jpg
WTF ??‍♂️ In the small end there is a roller bearing and X2 retainer washers that go on the inside of the piston.....like so ??20200523_084628.jpg20200523_083329.jpg
So when I put it all together and put on the piston it's such a tight fit ? ......so iv done this to one side now onto the next one ??20200523_083301.jpg
Iv sanded to two washers with oiled 600 grit paper to get it all to fit with enough movement for it to work properly ????
