Is it really plug'n play or do I have to add a gasket or something ? (because the squish band of the Polini head is ~0mm)

Thank you

Qisch band 0mm!

Compression!

Insert min a 1mm gasket and test it!

Optional an feed or head!

I want to know if there are simple plug'n play experience...

I read about it here on the GSF, but I just want to be sure it's working fine without any modifications...

Haven't done this until now, but as far as I know, the squishband is a delicate subject concerning the DR-Polinihead-Combo. As already written, use a ~0.8mm gasket first of all. If you are not satisfied with the power/compression, rebuild without the gasket.

In any case: Always measure the squishband, whatever you do!

For a gentle daily rider (DR + Popo head + SI2020 + original Sito Exhaust), what is the best squish any risk ? ~1-1.5mm ?

1,5mm no less.

Marc74 had tested it with a smaller squish. Teh engine became to hot.

Alright for a squish of 1.5mm.

What is the original DR squish size ?

By the way, the polini head is really better than the DR one ??

The Polini head provides more compression, and thus more power throughout the revs.

The original squish varies extremly. I have heard of squisches > 2.5mm, even over 3mm!!!

Hope it helps

Yepp, original squishes at the DR up to 3,5mm.

It seems that the Polinihead has a better layout.

Okay, thank you
