The kit comes with the pistons and \ rings already fitted.
\ This kit is only suitable for \ original 2cv etc. engine with full 9 blade fan and all engine cooling ducting \ fitted.
We do not recommend fitting to any application where \ the engine will labour, e.g. an AK400 towing a trailer would be really bad, the \ fan must be kept at a busy speed relative to forward motion.\
We do not supply larger jets for this performance improving part but you may need to increase petrol metering jets.
