Thank you all for the quick replies! I'm glad to hear it's an easy swap, I just ordered the parts needed for my bottom end rebuild, so this will have to wait a little while but I'll keep my eyes out for a good deal on a carb w/ the hot start assembly.
Couple more quick questions I just thought of, when swapping over to a new year does the jetting need to be changed? Or will the stock jetting for that newer year carb work for my 426? (I've tackled just about every job on this bike accept jetting lol)
And what year did yamaha
go to EFI? Wondering if I could go for the last year carbs were put on the 450s
I am about to put an 07 450 carb on my 01 426. The carb is on the bench now. I will be install it this week. Looks like a very straight forward swap if you have the throttle cable and hot start assembly in hand. The old throttle cable will not fit correctly on my 01. I will post my results when it's done.
What timing! Sounds awesome looking forward to hearing what you have to say about the difference in the power delivery/smoothness thanks!
