I have a Polini 154 and looking at getting a tune / blueprint on it, as lots of casting imperfections and it could be much better. Also I read the standard Polini compression is too high, so are people modyifing the cyl head to suit?

Read the leaflet that comes with the kit
You have to work out the compression and volume and lift on gaskets to suit and maybe machine the head
The pollini is from far a bolt on mod
