Carburation issues - A possible answer - Anthony Andrews researches...

We know that some of you have had issues with carburation of Triumphs and Anthony Andrews has been on the case...

Pod filters.

The port, arrowed below, needs to give atmospheric pressure to the diaphragm. So using a filter that covers the whole carb intake means the port is subject to ahigher speed airflow. This causes the diaphragm to not lift properly and the bike won't run any sense over 6,000rpm.




To allow the port to remain open to the atmosphere I used the original airbox rubber then fitted a pod filter onto it. With 150 main jets, the needles on the richest setting and pilot screws 3 turns out the bikes runs perfectly and averages 45mpg.

We'd be interested to hear your views and ideas too - head over to our Facebook page where there are some discussions. Many thanks Andrew !
