installed the 450R carb and WOW.....!!!

[Kentang4]

I've been reading a lot of post but I haven't seen the question of year addressed, sorry if I missed it...

Can someone tell me if using the newer slide versions of 450r carbs works as well as the older butterfly models? I have seen mention of a throttle position sensor on the newer carbs as well, is this an issue when putting it on a 400 or can you just cap off the wires and not worry about them?

Thanks for your help.

The older versions (2004 and 2005) are the best ones to use. The newer (2006 and newer) might work but not as well, IMO.

Yeah just cut the wires from the TPS.

Thanks for the quick replies. Any chance you still have an adapter laying around for sale? My hunt for a 04-05 carb is on. I'm working on a total rebuild, Hot Rod crank, 416 11:1, and I think a stage 1 cam, I like torque...

those adapters look great i would like one if you have anymore thanks for all the info if you dont know how to install a 450 carb after reading these pages your in trouble

Is it better to run the 450r throttle cable, or will the 400ex do the job? I've read both answers.

[Zeb400EX]

Idk about using the stock ex cable. I'm sure someone has, but it just easier to use the 450r cable.

I installed a 04/05 450r carb w/ adapter already installed on last week WITH the 450r cable.... take my advise

1) take your dremel either with a xmas tree bit OR a sanding drum and open up your intake boot (theres a lip which will prevent you from fully mating the 2)

2) install 450r carb cable ( the 400ex has a bend/curve at the carb which wont allow a clean install)

3) apply a thin coating of lithium grease just to ensure a easy install

4) you need to keep and use the stock 450r fuel line bc it has a step up in size (1/4 to 3/8?) - cut the final bend out of the petcock end of the hose and it will line up PERFECT with your petcock


im sorry i dont have any pictures, one day i will disassemble and take some shots
