The right cylinder head for the grand sport piston

Hi,

I have ordered a 136cc malossi kit, grand sport piston for this kit and the mmw cylinder head. Now i ordered this 38543700 while i believe i should have ordered this one 38543800.

Will this head still work with the grand sport piston or better to send it back and swap it for the 38543800?

And another question is if i need to make any modifications to the cylinder barrel using the grand sport piston. I am running a direct reed valve onto the barrel.

Thanks,

Dingeman

Hey!

To use the GS piston you need this head: 38543800

The other one you ordered would not work with the piston because the combustion chamber is different.

Okay thanks for your quick response.

I will return this head and swap it for the right one.
