Fcr39

Recommended Posts

Will a fcr39 carb off a 06 you 450 work on my 2012 drz 400 s

i doubt it. they might look the same but they probably wont work the same. i had a carb that came on my 09 and it looked exactly like the real 39mm fcr carb for my other drz. but it ran like garbage. the jetting was the same and it still ran terribly. the jetting never got better. its not worth the trouble to buy one and hope it works instead of just buying the right one...

Just save until you can afford the TT kit.  You might get a used carb that works out perfectly, but the odds are against it.  Yes, the TT kit is $550 but it comes ready to bolt on and with everything you need; no fuss, no muss and money well spent.  I am speaking from experience of trying a used carb on my bike that did NOT work out and left me out about $200.
