Boyesen ?

Recommended Posts

Ok so I was thinking about getting a boyesen accelerator pump cover on my bike sometime soon and was wondering what exactly it does and if it increases power? Ok so I've heard it eliminates the bog and better throttle response it that it?

I WAS looking at getting one too, but I hardly think a "cover" is going to give you all those enhancements. However, I never owned or used one so...:D

do a search for "leak jet" it will do the same thing, but save you about $80.

you were thinking about getting one soon but you don't know what it does nor do you know if it increases power?

type in "boyesen" under search, 3 seconds later...

i got one on my yz250f and to be honest, i couldnt tell a difference. its just supposed to let more fuel in the accelerator pump, but i think u can just do the ap whatever mod thing on thumperfaq and it'll do just about the same thing.

Its a more efficient design that the OEM cover. It does what it claims.

You can use the search engine as suggested, but here's the long and the short of it, according to those who use it.

The Boyesen cover helps the AP resevior refill faster. This keeps the AP from running out of fuel if you need to flick the throttle open rapidly several times in quick succession. For instance it would be beneficial skipping over the whoops.

The Boyesen cover does not eliminate the bog, increase power, cure your jetting woes, or water your lawn. It is not built to do these things. Flying through the woods or putting down the trails, you won't need one. Save the $$$ for something else.
