That's what I did I had one off a wildcat 650 I bolted the boot onto the 250 then just stuck that carb on. You will have to get a throttle cable I made one.

Since that system just feeds oil into the gas line ahead of the carb, all you need is a T fitting connect it up.

A 36mm would be the best size to use with that engine and should be real close jetting wise to start with.

Ok I remember now. But the pump is moved by a little metal rod that works off the throttle linkage opposite where the cable hooks up. Idk how you could still work that. Maybe a double throttle cable and some sort of linkage? Probably wouldnt be hard.

seems like a 32mm carb was a good match for that sled. fuel pumps from the phazers, enticers, or srvs delivered fuel well.

didnt read through all the posts, saw something about some 38's as a substitue. what i was saying is a mikuni 32mm roundslide would be a good replacement for your existing carb along with a fuel pump from the the sleds i suggested.

the carb you have now was replaced in later years like the early eighties with a keihin butterfly carb along with a fuel pump that you are more likely familiar with.

one thing about the bravos, theres plenty of them out there available for parts if you want to upgrade to the newer components. the old "all in one" carbs were and always will be a pain to service and the replacement parts seem to diminish in quality. seems like you can hardly remove a diaphram from the package without it having a pinhole or tear.

ya the carb is a big pain!!
well i figured i had to put a pump on, i think
thats my best option, i want it to start first
pull for the kids, i hated being 9yrs old, out in a
blizzard, pulling & pulling!!!

so i need a cheap single outlet pump. anybody??

well couldnt sleep, so got carb off, and
the new diaphram that was installed in feb
has a small split in it. sled was never ridden,
and only ran for bout 45min total.
the sled ran perfect for that time then
no fuel. what cheap parts!!! yamahadad,
u were correct. thanks so much.

moral of my story?? a new part, can be the problem!!
dont think because u replaced it,its fixed. dont rule that part out
because you took it outta a sealed box, and just installed it.

all im asking is, please learn from my mistakes!!!!
