Does anyone know what the thread size is of the fuel screw, 2007 CRF450X?
The threads on the carb are messed up and the new fuel screw does not want to go in... I would like to tap the boss if I can figure out the size.
Thank you in advance!

Does the stock one go in? Just checking if maybe the new fuel screw is the issue and not the carb.
I can't help with the tap number that would be required but if no one else knows I would bring the fuel screw to the hardware store and find the nut that fits it and then a tap that fits the nut.
Hope someone know more

Thanks for that, ordered one and it cleaned up the boss nicely.
Waiting for a new fuel screw, going to give the RD flex jet a go
Cheers,
