Guys,
I assume that I just did the right thing (help me here). I just bought a used stock YZ400F carb (FCR 39mm) in great shape for my motor that should be coming next week (10.8:1 416, stage 2 cam Hot Cams, etc). Stock jetting from what I have read is 45 pilot, DBNVR needle at 4th clip, and a 175 main. From the searches I've done here it looks like I should prob start w a 168 main and 52 pilot (please confirm). I'll also have to eliminate the throttle position sensor, etc. Rocky Ridge sells a kit of this. The carb also looks to have a plunger style choke mounted on the carb (that I prob can't even reach). I got it for $200. I know a lot of guys have done this with the stock CRF carbs which are pretty much the same as this one. So am I ok here? Any advice? Thanks in advance!!!
