hello all.., I've been reading up on all the topics of carb jetting and tuning and what not, and I just realized I dont have a brass washer under the main jet! Can this cause a big issue or can I just throw in any small brass washer to suit?

Also....my savage ran perfectly before starting my winter bobber build...in the meantime I've added a cheap ebay cone filter, and a harley dyna. My current set up is 155 main, 47.5 pilot. I live in Toronto and my riding area is about sea level with the occasional trip climbing 1000 ft in elevation. Anybody have any ideas what jetting changes I may have to do?

Thanks

Tony,.. I would get the factory washer... The thickness changes the distance between the main jet and the slide needle...
... or somebody with a carb apart, might be able to measure one for you...

I don't think the thickness of the washer will affect anything.  It does not change the height of the jet needle - it will just raise or lower the main jet a tad..however the change in height will have no effect on the level of the fuel in the float bowl (which is a potential way to make fine fuel mixture adjustments in the CV carb).

The needle jet (tapers needle attached to the slide) does not extend down into the needle jet (holds the main jet) - so raising or lowering the main jet with different thickness washers won't change a thing.

thanks nof, that would be great.

Ive got some good shots of the project that you'd all love to see....is there any possible way to upload images straight from our computer?

Go visit your local bike shop. They'll have 'em. Dave is right, the thickness wont matter. I had my carb off yesterday and thought of this thread. Other then being made from brass, there is noting special about that washer. I wouldn't hesitate to use a properly sized (no wider then the jet itself) zinc plated washer.
