Please note that this jet is a so-called "tuning part"and consequently has to be chosen with care.
Changing the jet, changes the mixture that is being fed into your engine.

If you have not modified your engine but simply want to replace a worn jet (they do wear and do age...), then replace it with the same reference as your old jet.

If you are unsure about which jet to chose, then please contact us and we will gladly help you.
