here is a drawing of the carb bore i used when making an adapter plate for a spectre air filter. the dimension are as good as they will get. the plate was cut on cnc and was a perfect fit. i may have missed some dimensions so if i did let me know and ill fix it

Greg, where did you get the idea for the Spectre filter and the adapter?

Yup, right about 2 months after I posted pics of the one I made in 11/09... LOL
The main difference between the two is the one I made is a two piece design that has an attached collar that still uses the rubber boot on the filter vs removing the collar and bolting it to the back of the filter itself.

But... neither of us was the first one to use the spectre filter on a VTX by any means, there was already a few guys using them. I liked the look of the filter but I just didn't like the idea of using some glued plastic or a PVC pipe end cap as the mount so I made one with steel then switched to aluminum after people started asking me to make them one.

Edit: If anyone is going to try their hand at making one, the biggest tip I can offer is that you don't want to make the filter centered on the carb. It has to be offset below the carb throat at least a 1/2" so it will clear the tank, if you center it it will rub on the tank seam. Keeping the rubber boot on the filter also helps bump it out a touch to help clear the tank, but it's still only about a 1/2" further out than the stock airbox cover was.

How does this compare to the hypercharger? I am only talking about knee clearance. Would my knee be annoyed but this sticking out?

i thought about using the pvc end cap but couldnt find one that fit the filter so i came up with the adapter. this drawing is for the carb bore and will work to make any adaptor

+1 Being the market is flooded with aftermarket intakes designed to fit HD's this style mounting plate can be used to make just about any inatke out there fit a VTX with a little work.

On mine it doesn't stick out much more than the stock airbox did, without using the rubber boot on the filter it would be pulled in about another 3/4"

In this pic the measuring tape was held up against the tank seem. My leg does touch it just a little bit on the back end, but I don't even notice it and it's never been an issue with comfort at all.

Awesome and thanks for those pictures and info. What can you use to cover it from heavy downpours? Like most of those big air kits being a rain guard? Not sure if that crossed you minds! You guys have seemed to already thought about every angle
