The CRF carb is 41mm and the TRX one is 40mm. Use the CRF one if you have the CRF motor.

Depends on what year trx and crf u have
2006 and below crf's had 40mm fcr carbs
2007-2008 crf's have a 41mm fcr mx carb
2006-up 450r's have a 40mm fcr carb
all the above have the ability to change the leak jet(adjust the accelerator pump)
2004-2005 had a 42mm carb without the ability to change the leak jet.
and the 2009 crf's are efi
Hope this helps

I have a 03 crf carb and it is a flat slide. I also had an 05 trx carb, it had a conventional slide.
