in the meantime the 'E' taper needle starts a lot lower and a lot later. 4mm anyone?
it cuts straight down and in to a point. this means my frinds that for a short distance the 'D' series is a thinner needle!!!!!!!!! and that friends, is the bit right where the pilot jet works!
thinner needle = needs smaller pilot jet.
just try to think of a wide based cone that cuts in to a pencil point and another that has a narrower base and comes to a fat blunted end.
remember that until you understand it all you don't understand any of it (i think, er maybe)

the problem with the 'D' taper is that if it is on clip 1, 2 or 3 the damn taper start is so low in the hole it can cause a slight bog.
the answer is funnily enough right up the other end. if you lean the MJ off the needle needs lifting. this is why when you read jetting Qs you'll note that there are dozens of jetting changes going on but that the bloody needle bobs up and down like a float on the river!
thus my dig at yami the other night.

Also, can any one tell me what the standard pilot air jet is on the WR450's. I guess I can take it out and look.
