needle adjustment mod

[dysfunctional33]

okay everyone... I am wondering with everyone talking about getting the needles to go in a little farther is it possible to just remove the small washer under the E-clip on my 84 VR or would this be to much of an adjustment?

Hey Mark,

Welcome to the VR.ORG Forum! (belated) What the buzz is about is you are trying to "lean out" the main jet so that you get better gas mileage. (with a slight DECREASE in overall performance) The main jet needle controls the mixture of air to fuel when the bike is under load. If you drop the main jet until it comes in contact with the seat, (which is what you will do if you remove the nylon shim completely) then you will shut off the fuel supply when you twist the throttle. The bike may idle, (the fuel comes from a different circuit for idle) but will not run much above idle. As to just removing the washer from the main jet needle, the sir clip will wear into the nylon shim, and the adjustment will not be the same from Carb. to Carb.

There is an inexpensive kit to re-shim the main jet needle here:

Or you can use a stack of washers that are thinner than the stock nylon shim.

OK. That makes total sense I was thinking backwards. But at the same time I don't have a nylon shim. I have a single stainless steel washer under the clip.

It sounds like it is already lean if the only thing you have is a steel washer.
