Hey Guys,
What needle valve size comes as standard in tm r1 ?
I’ve seen sizes ranging from 150 to 350.
Is this something to test out? I only do short circuit stuff.
However there is one track on the calander that would be quite long. Hitting 100mph in the kz class.
I think 300 is standard.
Better to play with atomizers, needle and jets
Partly depends on your fuel pump configuration. Certain configs may not require a return line. It’s easiest to stick with the 300, run either THIS pump of THAT pump, and have a “T” or “Y” fitting installed to allow for return flow back to the tank.
Perfect, Will try that. Another tuner said to try the 150. Yet he mainly does long circuit superkart stuff. He thought the 150 might suit short circuits better.
