What do you need to know.
First of all we need to know if you got the old Picco based Collari Innotech, or the new Innotech Rossi based engine. The Picco based engine is very fast engine but had carb issues and wore relatively fast, used to run it with a Nova carb. The rossi based engine i don't have experience with.
By the way those Collari Innotech Rossi engines are not made by Lamberto Collari Motorsport. There is a legal dispute about Innotech still using the Collari name.
Lamberto Collari Motorsport makes Sirio based engines now, Standard and Modified version done by his father Mauro Collari. very very fast engines. They are distributed by www.werksracing.com
There is a thread here about Coillari engines some post down. check it.
